Great video! 👏👏👏
I spend some time setting up profiles when installing beads etc. that way you plumb, square and level. Makes the rendering light work both scratch and top coat
Had that sand problem with selco years ago never used again since 👍👍
best vids ! lv seen mate that made sense. 🙂 just subbed
Hi Alex,
How do I control to gel half thickness for the scratch layer
In order to left the another half for top coat.
Another question is it's possible to use the plastic corners or flat to separate areas to work in small areas the reason probably is I don't have much time to finish a big wall myself in one day. Looking for the way to do it in different days
Just keep it on it bud, I'll change it if I don't like it 👍
Can you feel the difference between a good and bad batch of sand? I know that too much silt or mud will leave marks on your hand and too many large stones can be spotted, but does it feel different with too much fines?
100%. Fine sand is the worst of all. It’s an absolute nightmare. 🙁 it doesn’t rule, or float up and the water rises to the top of the mix. It’s so frustrating.
What would you do if you thought it was too fine? Would you start mixing sands with something a little bit more corse?
@@IanDavies tbh, its obvious if it is too fine. The render is almost unusable. To get us through the day we used lime in the mix which helps. But it isn’t great. Both times it happened we swapped the sand out. It’s a pain, but the cost isn’t that bad tbh. I ton of sand is about £60
I have a question please...
I used a scud coat at 2 to 1 and waterproof/ plastersizer
And scratch coat 3 to 1 and waterproof and plasterzizer
And now the suction on the scratch coat is drying too fast...
Am going to put another layer of scratch over it as we are using Webber white to finish.....
Just wondering could we put waterproof and pollybond in the next scratch coat .The mix will be 4to 1......
Need help please
What do uou bond the walls with?
Alex you are the only person i know who doesn't like the Cork handle.... 🙈...
😂😂 I know. We use to like them. But switching to the Nela/refina wooden handles they are much better. In our opinion at least.
The cork has fall apart on 2 of my nela trowels, well used BTW
What company makes that scratcher/scarifier you use?
Hi Alex 👍, thanks for your postings always interesting to see how other people do things. Personally still like two coats of pva 5/1 to seal ; then just before putting the scratch coat on, pva 3/1 making sure the 2nd coat pva is tacky as the scratch coat goes on. Welds the plaster to the wall👍 What water proofing additives do you use in your external renders.
You use pva on external rendering ?
Carbon wooden handle all the way 💪💪👆👆 swapped to carbon wooden handle couple months ago best thing I did should of listend to my dad years ago
I’m same. Took me a while to go over wooden. Best thing I did.
13 or 14” pal?
@@Nofixedabode859 14inch mate thin blade not the 5inch width give it a go if you havent before
Im right handed and work left to right....
Hi Alex, what mix do you use for a scratch coat?
Surely should be covered to stop the sun drying it out
Great rendering series Alex. Do you ever render fireplaces intended for wood burning stoves? Would love to see a video on that.
Hi Marcus
Yes we do. Haven’t done to many this year. But that’s a great suggestion. I will book mark this in for when we next do one.
@@AlexMorleyPlastering excellent! 😁
A right handed plasterer works left to right,lefty right to left
For skimming. Rendering and backing plaster the other way. 👍
Yeah m8 lay into the render less wastage
@@AlexMorleyPlastering you float up left to right. Doesn't make sense to lay on right to left. I was taught that in college when I first learnt how to lay on render. The render on the right hand side has been hit to quick with the sun.it needs splashing when it goes grey that fast. Keep it green and wet longer so cement sets harder curing it. Looked the same when you were scratching it. Needs to be a bit deeper than a few mm so the two coat can grip into the coat not just on it. Really enjoy your videos your internal work is excellent , I've learnt a few things from them.
Good vid lads, can’t beat the wooden handle carbons💪🏼 how’s the new trowel breaking in ?
The trowel is coming in ok. I have been using it to lay on a lot while plastering. We are working on a high end house so the finish has to be 👌 so I can’t use it too much in the later stages at the moment. But it’s getting there.
Should be a great trowel for someone.
@@AlexMorleyPlastering ah nice would make a great trowel for an apprentice 👌🏼
No mesh?
I always thought you needed to wet the brick first to help with suction. Is this the case or qad that done off camera or is it not necessary. Thanks
Not necessary if you have put a stabiliser on like SBR, slurry coat or render grip. .
Love nela trowels, but the cork has eventually fall apart, not a fan, great vids and workmanship BTW!!
Thanks for the feedback. I know what you mean about the handles. That has happened to me too.
Hello, Alex. Is there a way to successfully deal with cold joints in render? I realize that they should be avoided but sometimes that might not be an option.
Thank you.
Depends where it is. Most use an expansion joint. But that needs to be planned into the job. Or a horizontal bell cast (I don’t personally like this approach. Not my style.) - have a look at a company called bruford_and_ bond_plastering on Instagram for this style of rendering.
Great video how many meters do you reckon you get out of a ton bag👍👍👍
Tbh I usually just eyeball it tbh. However this is a calculation you can do which is online that will tell you the exact about you need.
But that would require quoting jobs with a a tape measure which I only do for m² rate skimming.
Roughly 40m scratch and topcoat m8
@@Nofixedabode859 cheers bud
Would you wet the slurry before applying the scratch?.
No it wouldn’t do anything. The skirt goes rock hard.
Ok thanx, how about after applying SBR
Does your render not slide on that slurry coat
No. There is sand in the slurry coat to give it grip.
Oh I see so it's like blue grit type stuff might give it a go on my next render job
How do you win the trowel
Hi Nestor
Once we have broken it in. We will be randomly choosing on of our subs. On the video we do the give away on, you will just need to make a comment (could be anything) just to show you want to be entered into the draw.
I will check the comments against the subscribers list, and use a randomiser to select a name at random. 👍
Sign me up Scotty
Surely you haven’t just a scratched one end in a day
No. It took about 3-4 hours to do the whole side of the house. Both Luke and Louie are improvers in rendering so I have to go over the whole house after they have put it on. So a side of a house is enough for me. 😎
