Hadn't used an I beam before on weber or k rend but what a treat it is to work with . Gets the walls flat as f**k and opens up the render to dry a bit quicker . Happy days
 
I've been working with another plasterer to get some experience using scratch renders, he doesn't use an I beam but i've heard alot of people use them here, would you use it just before its ready for scratching when you can just get a thumb print in it?

I haven't done any scratch render before and struggled to find someone who has. I know the guy is good at other aspects of plastering but going by what the guys say on here i'm not convinced he's knows that much about it and is kinda of making it up as he goes along. In saying that the finished walls that we done did look good.
 
an I bar will keep the wall true before scraping, even spraying a panel and ruling and spating flat your still going to get variants of a a good few mil, if your just going over with a scratch pad its poor practice, just wait until the sun shines near it.

Correct me if i'm wrong but from what i've read on here the proper method would be first pass, over with a serrated edge, second pass over with a serrated edge then spat, let take up a bit I bar, then once ready scratch back?
The guy I was working with would put a coat of around 8mm on scratch it and leave to set fully then another coat a few days later he would then rule with a speedskim and then leave it till it was ready to scratch. I don't recall anyone mention using a speedskim before.

Maybe a bit harder . Just go gentle with it but it gets the wall flat as fook .
 
Gears to wet or he's going over it to quick.
If you do it right you can get it on nice and thick without slumping.

Oh dear.:eek: What you on about a level? And you've been rendering on people's houses using that method.

It's easy mate, just run it over your wall to take high spots off.

fuuk that level off mate rule your gear with a serrated edge then spat over when ready is same day scrape you can gently run over it with the I section then finish off gently again with a long toothed scratcher gently again an it should be bang on don't forget hold the I section flat to the wall
 
Thanx a lot guys ,am sure it will make things easier for me but I'll keep you guys posted,am not new to the game infact 20 years this year but not done loads of this k rend stuff!thanks again guys.
