I always end up with sponge marks. After floating it up I leave it for as long as possible before sponging so the render is drier.....but still have sponge marks. Have seen some guys work and not a mark. Impressive.
is the sponge to wet or the render to dry mate ?
Ure starting 2 anoy me now every jobs 1st class lol done miles of that can't beat sand and cement new products r not the same same with wetcast even browning is not the same anyway very good job Jim from Glasgow
Yea a few new things out now i haven't used yet or might not ever use jim mate = ) thanks again for watching and supporting mate
Awesome job mate, like a sheet of glass by the end !
Cheers Mike mate have been rendering this week some and more today very little drying at all hard to get finished , Thanks again for watching :)
Crackin job... it aint easy to get it flat u made it look easy👍
Cheers mate :):)
very tidy finish liked the sponge finish
Hi mate thanks :)
Nicely done.
Thank you my friend
Always nice to learn! Good job!
thank you Sara :):)
The joys of exterior rendering EH Mac? ... I used to go over it with my rule or derby and some softer muck to fill in all the low/rough points ... it makes the whole rubbing up and finishing so much less painful ;-)
Hi Peter yes sometimes and near all the time inside if I am doing loads I will try close it in the the feather edge to make my rubbing life easier :)
You are the first video looks perfect 👌🏻 congrats
Thank you my friend much appreciate that comment :) we have a few more similar videos on our channel and always upload more every Sunday :)
mac plastering Thank you 🙏 I’m checking all your videos specially because I’m working with a cement fire pit and trying to make the outside looks half straight than what I see in your videos but not there jet 😕.
@@shalacasas9845 Haha getting sand and cement straight is hard work for sure I have a few demos on how i do it if you cant find them and want to see them let me know and can drop you links :)
Perfect finish
Thank you Juleen :)
🙌🏼😎
Thank you buddy have newer and new rendering videos inbound
Great job
Thank you Norma :)
SUPER thumbs up
Thank you :)
Top job mac looks really flat and smooth finish can I ask are you dry sponging ? Is that the way you always finish plain face render I always give it slightly light damp sponge, everybody has their own ways of doing thinga just wondering is their any advantages using dry sponge to finish rather than damp? Or is just down to personal preference ? Always interested and open to learn different ways and techniques Cheers mac keep up the good work buddy
Hi Mr Hill most times my sponge will be the same as you but if the render is wet I will be ok but I would all ways wash the sponge to make sure its nice and clean before use , thanks for the support mate :)
👍👍 good stuff mac ☺
Hi Murph mate thanks getting the sun for this :)
Hi mate, great video. What sand do you use? Building sand seems a lot easier to
use. Where as plastering/sharp sand seems very gritty and 'heavy' when it's mixed. Cheers
Hi buddy Thank s for watching :) Have a few newer ones on rendering up also, But i hear you mate Here our plastering sand is very nice and not to sharp but still gritty I find with a nice coat of 5mm up the grits dont bother to much on the finishing Hope this helps some
@Londonstain Ww4 How do you know he isn't a plasterers or an apprentice plasterer trying to learn and improve his skills, any one wanting to earn how to plaster will do so weather or not there are youtube videos on it or not otherwise how did we earn to plaster ? yes with getting our hands dirty and learning it.
Keep it up Mac!
Cheers buddy and will do :):)
Top notch vid
Thanks glad you liked it :)
It is how its done !
Cheers buddy :):)
Hi Mac. I am thinking that the amount of pressure on the float is important and to be consistent with it . Is this right ? Thank you :) Is it still very hot over there ? It is to hot here down in Dorset . Wll looks great,very impressive .
Hi Laura thanks for the support , yes pressure is the name of the game at this stage all about where and when to push hard and when to go easy and light but timing is important like most things in plastering nd rendering
Sounds like dog training ,when and how much pressure and timing be essential. You got a skill to last a live time there Mac : )
Oh yes and patience is needed in both :)
nice one
Hi buddy Thanks for the support :):)
Great work!
Hi Nina thank you my friend
Good video buddy !
Hey Sara thanks :)
Mac how are ye . was doing a bit of renering on a shed wall going on grand and getting it screeded up nicely but during the floating its getting tricky . when i float i seem to be dragging around bits of grit in the Render. are you using a finer sand or am i floating up to late
Hi jimmy I use plastering sand buddy and can be very gritty witch gives it strength if i was a betting man i would say you just need a slightly heaver coat (thickness ) Also any large pips/stones pick them out as ya go :):) Hope this helps some
Good job
Thanks for watching my friend :)
Good vid finishing some render off at mo on a bungalow soon pulls in what was your ratio fir this 3-1 very grey Ive normally tried 4-1? Which is best on old walls battered ones at that
my ratio here was 4 to 1 mate might look dark as its wet and the sand might be a dark colour on this job , when you say old walls do you mean block or brick ?
Nice work!
Thank you my friend much appreciated :)
Hi mac can i ask why do you use the scarifier and not the wide spaced scratch comb??
Hi James I think its better but everyone likes what works for them I will be doing a follow up video on this subject another live stream :):)
Nice job buddy but a little more sand would be easier to rub up
Thanks for that Julian mate hope your doing well :)
Can Lay that on way neater and take way less rubbing up and less filling in with a float
Thankz For *Your* Input
What water proofer would you recommend for the scratch coat?
I like the pink one from larsen
Why the float and not the steel trowel Mac ? Surely the aim is to close the surface? Brill vids bro keep up the great work learning so much 👌
That is the aim mate but the float dose a great job of doing in in my opinion much better than the trowel would,, as the float will work it in and help close it , sometimes if cement is trowelled / over worked it will crack very bad in lots of areas thanks for watching mate
Ok thanks for that Mac 👍🏻 every day’s a school day 👏🏻
That is true we learn new things every day a plasterer will always learn from every job
Have you any idea how to get a good float some boys say you can get a wet float and a dry float but they don't know how to find out which is which until you wear it in, bought a new emier float so hopefully it will be good
Refina sell good ones and rambootools I cant remember there is a polly one that breaks in faster as it is a little softer but then the harder one lasts longer but only wet one i remember seeing was like all holes in it so it wouldn't drag guy said he would send me some for the channel but never did haha
@@macplastering cheers lad have a cheap poly one broke in its good but if its any way soft you just may stand and watch it great if its dry though, bought a new emier dargan started producing them again so will break it in with roughing
Yes some the poly ones i have had break in so nice yes them emier ones are the job I mate I been thing of both buying a wooden one and making one LOL plastering and rendering crazy
Hi mate have done scratch coat how long should i leave it before i put top coat on
Ho Richard bro I always leave it to next day for very best results render will get better strengths this way mate
mac plastering cheers mate looks dry to me might do top coat later thanks for tips and getting back to me
@@richardbatchelor3297 Did you scratch it today or yesterday mate ?
Yesterday finish about 4 ish
@@richardbatchelor3297 Should be ok man if to dry might need a splash of water. We would always hit it next day if possible as its nice and fresh with not to much suction :) Let me know how ya get on mate
Maximus 😁
My friend dont you mean macsamus
Hi Mac what mix ratio do you use for your top coat
Hi Wayne buddy I would usually do a 4 to 1 mix 4 of good clean plastering sand to 1 Portland cement
Thanks again for watching and commenting I have a few more rendering videos might be of some help also all the best MAC :)
@@macplastering do you add waterproofer to your top coat mac and if so how much to a belle mix . Thanks .
@@stumetallicafan hi Stuart buddy diffrent brands have diffrent amounts needed best to read and follow the guidelines , i think on this one im using the pink witch only need a cap or so per bucket of water as its pretty strong and good .
@@macplastering thanks Mac it's interesting cos I've worked with guys that will use about 500- 600ml to one barrow mix or about 1500ml to a site mixer that holds about 3 barrows . They say u need that amount because it meant to do as it's called "waterproof"
@@stumetallicafan so they use more or kess 2 cans of coke for one small mix dose sound extreme but gota do what works for you , remember you need coats to bond to eatch other and also sand and cement is water resistant on its own but i say read before yiu use as if you go by the book you cover yourself
How I make the sand and cement render straight before I finish it =ua-cam.com/video/OMK-asylju0/v-deo.html
Good stuff. I have an 8 metre wall to render tomorrow and i dont know if i can do it all at once, can i do it in two goes? If so do i need to use some sort of tape to connect the edges, also what would you reccomend for big holes in brickword, should i fill it with scratch coat and put some sort of metal grid sheet over it?
Hi mate yes filling big holes 1st while doing your scratch coat would make it easier to finish some wire mesh would help also should reinforce it some and reduce cracking make sure use stainless or galvanised you would want it rusting if i do big area I would coat so far get it straight then coat some more fall back rub and finish then start coating again if this make sense as it will keep your joint wet and fresh
@@macplastering thankyou! By fall back rub do you mean using sponge to wet it?
@@macplastering ah sorry i know what you mean by fall back rub now, thanks a lot buddy for the fast reply im suscribed! I hope it doesnt dry too fast expecting 25 deegres tomorrow 👍
@@adrianadios5041 As in doing it in stages but same day like ut some on then get straight then coat another section then go back finish the 1st stage of render then coat the final stage then finish middle then straighten up last stage then finish it
@@adrianadios5041 you can wet wall down to help slow it also some water proffers in scratch coat the day before will also slow down the suction
What materiales dobyou usted There???
Marmolina? Cement? What is the correct mix???
Hi buddy this is a video of me mixing for the 1st coat = ua-cam.com/video/Tsw-t8mwLRI/v-deo.html
The sponge is super wet or dry ?
Semi wet mate not to wet or dry
Nice job how long do you normally leave it before floating
Hey Wayne buddy Thank you and thanks for asking this question, its hard to get all the info into a single video why i have been making many over 300 haha but to answer your question the time will depend on many things especially temperature / wind a hot sunny windy day and the stuff will dry quicker than the clothes on the washing line :) but i do small test like poking it with my finger to get an idea how well it is setting you can also use the float as a test if worries about damaging the wall do this testing on an area not seen as much .... but a little finger hole here and there can be easily rubbed better later on when it is more set or if still soft you know to wait longer , in winter this can mean put more on in the morning and then wait for it to set HOPE this is helpful mate ?
mac plastering so when you you start to float it you shouldn’t be dragging any moisture to the surface ?? someone said wait till the render gets a skin on it does this make sense ??
@@waynebrewer2497 Makes perfect sense buddy you will feel the difference you can float it when its wet but will take more skill with the hand and when it sets a little more will take more power to rub you are wanting an in between for ease if you get me
good video , too often the talking is confusing , you showed how and easy to follow , well done
Hi Robert and thanks buddy We have another one on finishing render coming out this weekend :)
Do ye do a nap finish on render like we do down in parts of the South ya do it with a orange sponge float
is that rubbed or dabbed
@@macplasteringflick water at the wall with a brush then run it up with the sponge then tap it against the wall
@@arthurmorgan1338 Never done that finish on render but could imagine the finish , did a diffrent finish on a chimney with k rend that was asked for but just looked liked k rend that was scratched of only a little finer , not the way i suggested but it is what was asked :) Looked good and still dose
@@macplastering nice 1 it's kinda a like a artex stipple but on the outside I'll send u a vid someday
Yea mate defo do sounds interesting :):)
The wall already has wet cement on it, I wanted to see the whole process
will try to make a start to finish one buddy , there is a few more vids o the Chanel where i coat it and straighten up ,i could put them all together for a more complete video but would be long

is that plastering sand you are using to fill in ? I tried doing that and the little stones in the plastering sand dragged scores and tracks in my work. I couldn't get a decent rub down and fill in finish until i mixed some render using building sand.
yes 100% plastering sand mate sounds like you had the gear on a little to thin I wouldn't recommend building sand as it will lack strength, will shrink more, and more likely to crack but some mixed in shouldn't be to bad .... Its the grain that binds together that makes it strong just like concrete
just a titbit you might find interesting. My ongoing job that i mentioned before, at the stage now where Ive stripped pebbledash and am rendering over old stuff, holes and lumps, expandxed metal etc and last but not least a shiny concrete head. This head has been a torment. NOTHING will stick to it. No matter how I scudded it, with or without unibond etc, the scudding rubbed off with my hand the following day. Where it had dribbled down the wall it was welded to the wall and hard as flint !! But c ompletely failed everytim over 5 days to stick to this head. I even brushed it with acid which pockmarked the head and roughened it but still it resisted. Finally contacted the makers, Scott and somebody, who said they used ' the cheapest oil possible' as a release agent when they are casting these. Make a slurry first and pour it ijto the mold directly on the oiled mold. So I'm guessing that the release agent has been absorbed into the surface slurry of the head because it seems actually waterproof !! At my wits end when an old timer told me to strip the head and use exterior tile cement on it, then scratch the tile cement. just did that yesterday and it has set like concrte and is welded to the head, so fingers crossed to finish rendering the whole thing including the head. Sorry for the long post but if it helps anyone who gets one of these waterproof heads .
Thought i replayed to you buddy but it must not have sent LOL im surprised tile cement worked but sbr didn't maybe it was a combo of all these things you dont witch worked as the cement might have cleaned of the oil / release agent off it ..... glad you got a bond to it mate sounded like a right pain that job
it's a struggle indeed, doing EVERYTHING inside and outside this 'ol house' but the location makes it all worthwhile. 200ª uninterrupted view of Strangford lough, 3 fields away, at the bottom of my garden. But a lot of bodgy work to overcome. Finished the rendering and the tile cement worked a treat.
Sounds a real nice spot mate will be great to sit there in the sun I am sure :)
Would you ever do a Knapp finish ?
With the cores sponge float ?
@@macplastering ya . That's what we do in Galway . Very rare you would see a sponge finish down here
I never been to Galway looks a real nice part of the country its on the to do list :) Yea mate every one here wants smooth smooth inside outside unless dashing
@@macplastering I'm doing some finishing tomorrow so I'll post a pic the Knapp finish if I get a chance
@@simonmadden2986 YES mate drop me a link to the clips you upload :)
Is that a wood float Mac?
I Brain mate got asked this on another rendering video I have , no mate its a polyurethane float but might make myself a nice wooden one some time my old boss had a few and they where good
Do you use the sponge dry or wet???
most times would just be slightly damp mate
@@macplastering thanks mate
Anytime mate
@@macplastering I started fining this morning took ages to go off coz of the damp weather then it started raining so i scratched it and go back another day. Typical British weather 🙄 😂
Darren thats a nightmare mate had the same thing doing plinths here washing off on me and never drying but what can we do but try
2:01 exhaust leak ;)
Ops
I have said this before but I could listen to you talk forever.
Thank you steph :):)
that's too strong a mix for a top coat. looks like 3 or 4 to 1 to me. should be 5/1 and 1 lime or it'll crack.
So you can guarantee your mix wont crack ?
I am fine with the way i do things myself mate been doing it long enough and get repeat work
But here do what works for you
@@macplastering No, as you know you can't guarantee it won't crack but by using a weaker mix there if far less chance.
@@MrDekaying agreed on that eatch mix weaker that the previous
