Hey mac just started watching some of your videos, i jist got a shed built, 9 " cavity blocks, do i need scud coat before scratch coat? Chers bud, Ger dublin
Great skill sir and very informative video, i did my wall before i watched ur video wish i had watched video then did my wall as i messed up on scratch coat left it 2 long couldn't get the scratcher in scratch coat for next i know to put mortar on whilst scratching it but thanks for sharing ur knowledge best of luck in wat u do 👌
Hi mate hope your doing well, Than you for the support man we learn from our mistakes next time you do it you'll be way ahead :) Thanks again for watching and commenting :)
Oh so cool man have you make a video on it? for sure hawks / plastering hand boards can be very helpful tools the more tools we have the easier our job become I think anyway :)
Thank you colin mate have a good little video out this Sunday kind of the next stage of last Sundays video :) And thanks again for the support Colin mate
I see a lot of rendered block walls around now where you can see all the joints cracking through the finish-i put this down to the pre mix bag renders that people are doing around 5-7 mm thick and only one coat.We always did Scratch and finish coat on Block which ended up around 15mm thick at least.
Yes buddy i am the same always do the 2 coat system much superior job all round i think minumum for 2 coats is 10 mm to 12.5 mm but older walls do tend to take a little more ,thanks for watching buddy and taking time to comment
@@macplastering been hunting everywhere for thickness recommendation! Watched heaps of your videos now - thanks mate! My Dad was a plasterer but passed away last year. I’m about to have a go scratch coating a garden wall I just built for first time without him so your videos have been guiding me through!
Fair play mac,theres a lot of bluff and bluster on a lot of other videos,your straight to the point and clear demonstration of the skill,I've seen some plaster donr which dries with a map of hairline cracks barely visible, what causes this,is it too much cement in the mix?.
Can be also the wrong sand could do this to a more clay like sand is going to tend do them little hair line checker cracks every where ,building sand would be a type of sand that could do this mate , Thanks for the support mate means a Tone :)

Hi bud not sure if you seen but I have a vid uploaded on how i did this mix and my top coat will be the same only more sand hope you get a look at it , but here we have very good plastering sand its pretty course like sharp sand but graded well and very nice to rub up and float
@@macplastering can you please help me out. I have rendered a wall scratch left couple days wetted down then top coat. Fethererd off then rubbed up with float but when I run spounge over it's like it's rubbing top coat off & little hollows appear & it's very sandy. What am I doing wrong plz mate. 4/1 scratch with 5/1 top sand I using is holm sand , building sand, Sharp sand any info please will help me out as I got to redo it again. Thanks mate plz reply
@@redsreds6598 Hi buddy hard to know exactly whats happening with out being there and seeing it , But sounds like it has gotten to dry sometimes if it rubs nice and looks very tidy it might be best to not sponge it, as this can cause the surface to be over worked and tear like you say , My mixes are usually 3 to 1 then 4 to 1 with plastering sand , have you used any plasticise ? or retardants to help slow the set / suction down ? was the wall wet down , some times a wee trowel full to test suction is good to help you judge timings and dryness ,plastering and rendering is among one of the hardest jobs to do in my eyes, so my factors come into play and experience is a big help in judging what is going on and how to make life easier , but you only get this experience with time and jobs done , no one plastering has always got it right every time so dont be disheartened either and i am glad you are giving it another go. For me to help Let me know whats the background brick block Was plasticises and water proffers used Was it a hot day sunny / windy is it old or new building How do you plan fixing it / chipping off / or attempting to go over (not recommend ) Size of wall and type of wall high long gable end As much info as possible buddy even if you can drop me a picture Email macplasteringservices@hotmail.com
Hey I just had a quick question after watching this playlist. For my pebble dashing can I just follow this video for the scratch coat where I just do the one layer of plaster or do I have to follow the whole playlist and do another layer to straighten and then follow the float finish sand render smooth. Or can I just follow this video with Only one scratch layer for the first layer (just one layer no need to plaster over and follow all the videos in this playlist) and then wait a day and then do the 4-1 top layer with the white cement mix and dash the pebbles on?
Yes mater this is the same 1st coat / scratch coat for both smoth render or a dash finish render only a wet dash would have another coat called a brown coat
Hi, I;m partially rendering an exterior wall that part of will be below ground level. Going to use sika 1 waterproofer. would you recommend using the waterproofer in the scratch or top coat? Will the topcoat not key if sika 1 is used in the scratch and left overnight?
it will still bond if in both buddy just the top coat might not set as fast ... best to read the instruction also as some stuff differs thanks for watching buddy :)
Great video and very clear instructions as always Mac. and I learned something as I didn't know cement generally caused burns - I'll keep that tucked away in the back of my head somewhere in case it's needed info someday. I hope your week is getting off to a good start and and you're getting to enjoy some of the summer with your family. Have a good one! :)
Things have been goodbi have been extreamly busy in workand today lol but its a good complaint .... oh yes cement burns the skin very bad even more so if you are cut it will burn them areas even worse thanks for watching Annie hopenyour doi g good also
Hi Peter mate would be a hard call dont like going over paint outside but would try to get off all lose paint and try key it up some like with a wire brush then scud coat and or scratch with lots of sbr in mix and on wall , but it will only be as strong as the bond the paint has
Hi mate I used to use one like this for rendering - amzn.to/3gOItbb and an all round refina like this one - amzn.to/3oZF8Zt but the type of trowel is really down to what you like these are ones I have got on well with over the years
Hi Mac thanks for your great videos I just subscribed. Can I ask you a question about the type of sand to use for rendering. Is building sand finer than rendering sand? I am based in Devon and a lot of builders merchants seem to call the plastering sand 50/50 Which I believe is half sharp and half fine sand and washed. Do you think that would be the same as what they call plastering sand? Thanks again Chris.
Hi Chris mate appreciate the support means the world to me, it dose sound possible that its half building and sharp here there is a builders that sell wht they ca plastering sand but its very gritty indeed its ok to use but if you go to thin of a coat it can be a nightmare with the grits and it drying quick if i was you I would test a small amount of it 1st see how you get on mate
@@macplastering Thanks for your reply much appreciated, yes the 50/50 sand is quite gritty here too and they call it plastering sand!! I think I will just get the fine yellow building sand as I want to get a nice smooth Finnish. Maybe I could use the 50/50 as a scratch coat to leave a bit more of a key for the top coat which can be done in the fine builders sand? Thanks again Mac :)
@@Chris-uu6dg Only thing is finishing with building sand can be tricky also again if at all possible do a small area for a test 1st , building sand tends to slump on walls and whne finished and dried out cracks much more than plastering sand would due to it's fine grains and acts more like clay , if you think of mud that has dried out in the sun thats the kind of way it cracks and sometimes you'll only see them when its wet yes this can happen to both sands but much more on building sand the sand i use is gritty but it is then best for plastering , I will have to try do a video to show examples of this ,but for sure if you can test some before you do anything big is the best way
@@macplastering Hi Mac, thank you so much for taking the time to reply really good of you mate!! A video on the different grades of sands and their uses would be amazing as it is a bit of a minefield for beginners to know which is best to use for rendering and on different types of surfaces. Just asking for plastering sand at a builders merchants is a bit hit and miss because they vary so much, and most just want to flog their sand in stock. As I am a beginner its hard to know what to look for like how gritty it should be and the size of the grit. If you get the chance to do a video on that I think it would be very popular. Cheers for all your help mate. Chris
Any idea what makes render more "sticky" so there is render falling of the wall when applying it to the wall? Is the wetness of render only factor taken into account here or must anything else be added to cement and sand mix?
This is a how i mix my under coat - ua-cam.com/video/Tsw-t8mwLRI/v-deo.html you might just need some mortar mix / plastasicer to make your gear more workable and or an under coat with the likes of sbr in it 1st or a scud coat to give a great key for top coat such as this video = ua-cam.com/video/PxfawvJqCck/v-deo.html if need any more ideas or tips let me know but hope these help you some
Mac how are ye ciaran here in mayo . just a quick one , i generally do a 4.1 scratch coat at a depth of around 10mm and a 5.1 top coat at at the same depth . Im currently doing a wall that i have already scratched out to about 10mm but im going to be applying a top coat on it 5.1 at a depth of around 12 - 15mm im stuck with this extra depth as the beads im using are that depth and with the lock down on, im going to have to go with them i think . what do you reckon with the top coat being thicker but weaker. is it stil an ok way to go.
Hi ciaran mate hope your doing well down there and you and yours are safe and well , Mate I would think you would be ok cant see anything wrong with it might want to do it in 2 coats though same day just to stop it sliding might be worth a thought if you get what i am saying but the weather we are having it should dry nice :) Thanks again for the support on here mate
@@macplastering great mac thanks for the reply i must get onto your charity page and donate ill send it to some of the buddies a well . one last quick question . Iv completed a scratch coat to the back of the house it went on well but in a few spots i didnt get a very deep scratch because it dried a bit on me . i was woundering if i could add a bit more grip to it, maybe throw a bit of a light scud mix onto it in those spots.
@@jimmyc9925 a scud on it sounds like t would help as long as its a weaker mix than your scratch coat and stronger than the top coat if this makes sense mate mabe get a little sbr in the mix to , is there a way to score it with a grinder or would that be to dangerous and difficult? Sound man any support the charity's get is great as them like most places are going to struggle with there being no events going on to raise funds
@@macplastering sound thanks . the scratch was a 4:1. What effect would a light 2:1 scud have on the finish coat or would it conflict more with the scratch coat its going onto? I can always go with a 4.5:1 if thats the best. Once again thanks for everything.
@@jimmyc9925 Was always taught if you go stronger over the top it will blow off and have seen it on jobs I have stripped of that t just shells of top layer, the sbr in the mix or on the wall might cancel it out but it being stronger it still might crack on you mate is it a big area ?
@@macplastering How far away are you from Southampton brother? Got ready 3 rooms for plastering and the rest 2 rooms around November-December...0773941037 Regards mate and keep on the good work.
Hi mate we done it years ago loads and was told to do it that way then they changed and wanted it just straight k rend and said they wont stand over it if it was on sand and cement have drove past the ones done about 16 years ago this way and they are still on was a big site I figure they wanted to just sell more of there own product but then again if it fails its on you best to do it there way and then again if it fails they probs still say it was the way it was done
Very well done.....its pretty basic stuff Just alot of labor and if your body not used to it, you will get best sleep of your life😂 Gloves help the knuckles from being scraped raw....
Hey buddy , I would always prefer to leave mine at least a day before gong over again , but to answer you it can be done but I wouldn't relay recommended it
Just adding a bit of input if that's ok as far as I know you can do k-rend finetex scratch back in a 2 coat pass on the same day onto block work as in finished the same day I will try and find out more on this but I agree with mac sand/cement render is 1st coat then next day or longer 3nd coat👍👍👍👍
@@onpointplastering Oh yes k rend and webber , the monocouche renders can be done same day and also you might need accelerators but they need to be measured perfect as they can discolour it so to be safe you need to add the same amount every time
hi Patrick mate hope your well, I only do it if necessary but mind you would loved to got another day outa it :) have an old block wall coming up its going to get the full works and have time to record it all :)
Hi Pat mate I do prefer the old way for sure what do you think of the pvc beads? I did use a bead at the far side as was not able to nail on a rule/timber
doubt it on this garage was a diy build and they left the back and side out (rendering wise) when it was all first done not sure if you can see but the sides didn't put no base or plinth in and again the back is higher than the inside and the fronts level as its a garage I suppose that makes sense if you want to drive a car in. could be some dpc in but not 100% mate
Again when is comes to the under coat the scratch coat it would be done this way mate only after would you add a plinth or base but yes you could bed the stop bead in at this stage
Hi John thanks for the comment and glad its good to watch thank you , yes sorry the ratios was in a previous video I think i got them in a playlist in channel but will drop you the link to the mixing vid - ua-cam.com/video/Tsw-t8mwLRI/v-deo.html Thanks again for the support mate :)
@@phillymartine5849 Thanks Philly LOL inside out upside down round the wrong way LOL Yes but I think the guy was just taught diffrent there is 100% no difference its all about comfort and what works for the individual
Hi mr mac following ur videos 4 or 5 years now not impressed with this 1' no scudding 2 mixing mortar plasterciser to scratchcoat ( not for external use in ireland creates hollow pockets reacts to cement bad job) should be edgeing your scratchcoat for flat sharpe finishing
Hey thanks for watching for 5 years shame your 1st comment is this one a negative every one dose render diffrent for sure and I have to this day had no problems with mine but thanks for your input , I would rarely scud decent block , but yes if I could get another days pay for every singe job i done why not haha but life is not just a black and white picture I am sure you know , you dont like the finish I done on this one? as it is the very next video ? hope my fellow country man will stay in touch and follow us for another 5 years :)
i find i dont drop much to be honest buddy and i been working at it long enough to know what is more comfortable witch is also where you wont drop much at all, But keep doing what is working for you
Just look at the floor after the whole wall is on very little on it so starting left or right is not important simply you have been taught that way mate
Not sure what SA means but its only wasting your time as you know how to plaster witch is also a waste of time your watching plastering videos if you all ready know how ?

Im currently doing a wall that i have already scratched out to about 10mm but im going to be applying a top coat on it 5.1 at a depth of around 12 - 15mm im stuck with this extra depth as the beads im using are that depth and with the lock down on, im going to have to go with them i think . what do you reckon with the top coat being thicker but weaker. is it stil an ok way to go.
Hi ciaran mate hope your doing well down there and you and yours are safe and well , Mate I would think you would be ok cant see anything wrong with it might want to do it in 2 coats though same day just to stop it sliding might be worth a thought if you get what i am saying but the weather we are having it should dry nice :) Thanks again for the support on here mate
@@macplastering great mac thanks for the reply i must get onto your charity page and donate ill send it to some of the buddies a well .
one last quick question . Iv completed a scratch coat to the back of the house it went on well but in a few spots i didnt get a very deep scratch because it dried a bit on me . i was woundering if i could add a bit more grip to it, maybe throw a bit of a light scud mix onto it in those spots.
@@jimmyc9925 a scud on it sounds like t would help as long as its a weaker mix than your scratch coat and stronger than the top coat if this makes sense mate mabe get a little sbr in the mix to , is there a way to score it with a grinder or would that be to dangerous and difficult? Sound man any support the charity's get is great as them like most places are going to struggle with there being no events going on to raise funds
@@macplastering sound thanks . the scratch was a 4:1. What effect would a light 2:1 scud have on the finish coat or would it conflict more with the scratch coat its going onto? I can always go with a 4.5:1 if thats the best.
Once again thanks for everything.
@@jimmyc9925 Was always taught if you go stronger over the top it will blow off and have seen it on jobs I have stripped of that t just shells of top layer, the sbr in the mix or on the wall might cancel it out but it being stronger it still might crack on you mate is it a big area ?
Hi Mac what size render beads do you use? Thanks 👍
this one where 8 foot long beads mate but most time i just use rules / timbers Thanks for watching buddy :)
@@macplastering hi mate I meant the thickness please, thanks for the reply and keep up the good work on the videos they have been very helpful👌
@@haydencox502 Oh sorry mate i would say about 20mm total
Good vid
Thanks Mark man appreciate the support :):)
Did you go to some kind of college or courses to learn that or you just came to a building site to work as a labourer and learnt that on the go?
I did go to a college yes but you learn best on site working and learning on the go
Great job
Thank you Norma appreciate you support as always :):)
Wavy lines, lateral and vertical pull will have resistance. Straight scratch lines are prone to cracking on lateral pull.
Might do a video on the very subject thanks for watching
4.33 The view of your hole indicates the quality of rendering?
Oh my my LOL builders bum
@@macplastering Farty bumy?
@@macplastering "Sexy" rendering satisfaction guaranteed....lol

@@macplastering How far away are you from Southampton brother? Got ready 3 rooms for plastering and the rest 2 rooms around November-December...0773941037 Regards mate and keep on the good work.
hi guys just seeing if i can put k rend over the top of cement scratch coat many thanks
Hi mate we done it years ago loads and was told to do it that way then they changed and wanted it just straight k rend and said they wont stand over it if it was on sand and cement have drove past the ones done about 16 years ago this way and they are still on was a big site I figure they wanted to just sell more of there own product but then again if it fails its on you best to do it there way and then again if it fails they probs still say it was the way it was done
@@macplastering hi mate ok cool coz the bass coad primer expensive so i will do a sand and cement scratch coat first thank for your help
@@rclink1866 I have a k rend demo mate it can be done in 2 coats straight onto block without needing any undercoats
@@macplasteringhi mate i need to go over breeze block would i still need a sand and cement scratch coat
@@rclink1866 mate this is the way i do k rend on the most ua-cam.com/video/-U3Cb4-jp80/v-deo.html
Very well done.....its pretty basic stuff
Just alot of labor and if your body not used to it, you will get best sleep of your life😂
Gloves help the knuckles from being scraped raw....
100% man yea my hands are cut to bits the last few weeks
Is it a pure cement or mix with sand I'm a beginer
Hi Tata temyoung no its cement and sand I show how i mix it here - ua-cam.com/video/Tsw-t8mwLRI/v-deo.html
Hope you subscribe for more :)
Hi mate can you scratch and finish in one day?
Hey buddy , I would always prefer to leave mine at least a day before gong over again , but to answer you it can be done but I wouldn't relay recommended it
@@macplastering cheers mate
@@jamietalbot7254 Any time buddy :)
Just adding a bit of input if that's ok as far as I know you can do k-rend finetex scratch back in a 2 coat pass on the same day onto block work as in finished the same day I will try and find out more on this but I agree with mac sand/cement render is 1st coat then next day or longer 3nd coat👍👍👍👍
@@onpointplastering Oh yes k rend and webber , the monocouche renders can be done same day and also you might need accelerators but they need to be measured perfect as they can discolour it so to be safe you need to add the same amount every time
Do you not scud the wall no?
hi Patrick mate hope your well, I only do it if necessary but mind you would loved to got another day outa it :) have an old block wall coming up its going to get the full works and have time to record it all :)
I live in Perth Western Australia
sweet , hope you guys stay safe and that the sun kills it like so many think , are you in winter now though ? is it still warm ?
Why corner beads that rust, do the aris the proper traditional way off the stick.
Hi Pat mate I do prefer the old way for sure what do you think of the pvc beads? I did use a bead at the far side as was not able to nail on a rule/timber
Is there no dpc ?
doubt it on this garage was a diy build and they left the back and side out (rendering wise) when it was all first done not sure if you can see but the sides didn't put no base or plinth in and again the back is higher than the inside and the fronts level as its a garage I suppose that makes sense if you want to drive a car in. could be some dpc in but not 100% mate
Again when is comes to the under coat the scratch coat it would be done this way mate only after would you add a plinth or base but yes you could bed the stop bead in at this stage
The cracks are starting to show MAC at 4.45mins
Subscribe for more LOL
Good enjoyable vid, but you never stated the ratio, sand to cement xxxxxxx
Hi John thanks for the comment and glad its good to watch thank you , yes sorry the ratios was in a previous video I think i got them in a playlist in channel but will drop you the link to the mixing vid - ua-cam.com/video/Tsw-t8mwLRI/v-deo.html
Thanks again for the support mate :)
How is been lock down going.We are not on lock down the only thing open are take away liquor stores supermarkets
Hi Trevor buddy we are doing ok not much open but like of Tesco and food shops where are you in the world mate ?
starting at wrong side of the wall
Dont be that guy just because you do it diffrent dont mean im wrong or you are wrong besides you dont know i could be left handed LOL
wrong side and inside-out haha all about the end result and if it is there years later
think Mac has this in the bag
@@phillymartine5849 Thanks Philly LOL inside out upside down round the wrong way LOL Yes but I think the guy was just taught diffrent there is 100% no difference its all about comfort and what works for the individual
Hi mr mac following ur videos 4 or 5 years now not impressed with this 1' no scudding 2 mixing mortar plasterciser to scratchcoat ( not for external use in ireland creates hollow pockets reacts to cement bad job) should be edgeing your scratchcoat for flat sharpe finishing
Hey thanks for watching for 5 years shame your 1st comment is this one a negative every one dose render diffrent for sure and I have to this day had no problems with mine but thanks for your input , I would rarely scud decent block , but yes if I could get another days pay for every singe job i done why not haha but life is not just a black and white picture I am sure you know , you dont like the finish I done on this one? as it is the very next video ? hope my fellow country man will stay in touch and follow us for another 5 years :)
A bit of the plumbers crack going on
I relay need to get that tattoo sorted saying subscribe for when that happens LOL hahah thanks for watching mate :)
your right handed sir you find you will drop less if you work in to your work
i find i dont drop much to be honest buddy and i been working at it long enough to know what is more comfortable witch is also where you wont drop much at all, But keep doing what is working for you
Just look at the floor after the whole wall is on very little on it so starting left or right is not important simply you have been taught that way mate
Should always rule off scratch coat
Not at all
I would only ever rule it off if it was bad shape in all honesty but hey wouldn't harm any
absolutely no need at all. Anyone any good can put it on even enough without the need to rule it.
Lol....now you're just showing off!
Thanks for watching the showing of will be on another video LOL
My eyes hurt
why is that ?
Nice informative video liked keep up the good work and feel free to check out my latest video and thx plus sorry for the disturbance and inactivity 🙏🏼
Thanks bro :)
This is a waist of time .In SA that wall must take us 2 hours
Not sure what SA means but its only wasting your time as you know how to plaster witch is also a waste of time your watching plastering videos if you all ready know how ?
@@macplastering we plaster 10m wall per day
@@jesuslord2098 But if you could do less and get the same would you ?
I think the top coat should go on before the undercoat.
depends where your standing suppose
