Slc Method, My Way - How To Use Self Levelling Compound Properly

[The Legend; Phil Hobson RIP]

I have posted this type of slc method before, just thought I would repeat it if I have got the pics right, dots set by laser runners made from 3-1 compo plus polymer and rapid set adhesive.

I find I'm doing it in "bays" more these days Phil,,after looking at some pics you posted once

i use 150 x 150 white wall tiles cut into 50 mm strips and and use these for level screeds when latexing like your method Phil

Cheers Doug, my way of forming the bays is to set dots with laser to FFL less tile and adhesive, so dots are the bed, I then fill in between the dots using 3-1 compo with the rapid set and polymers, these runners once gone off can be flooded with slc forming perfectly flat bays/floors,

One tip for anyone trying this for the 1st time, when your dots have set lay the compo in between the dots, then use a Stabila level to form a nice runner, (always wet the level) cut off the excess compo from the sides and slide the level off leaving a nice neat runner.

Once the runner or screed has set you can flood the bay with slc and fill with the help of a feather edge. hope this makes sense, and maybe helps someone.

Much like the old Semi-dry screed method Gary, sometimes the old ways don't go away.

I have been screeding outside last week Phil with 3-1 sand and cement and waterproofer laid into a slurry of SBR & OPC , i always lay strip's of screed and then rule -off to them works great every time !, But i have never used' it for SLC , so if i need to, i will use THE PHIL HOBSON method :hurray: from now on mate thanks Dave

I always seem to pull dips in to my work when i run screed channels and am more comfortable using wooden laths when screeding but i only screed 2-3 jobs a year and tend to drop lay when fixing with sand and cement do you have any tips to stop me cutting into my level screeds when ruling off ?

Out of interest , when you say fill with a feather edge , do you mean flood first , let set , then finish with the FE?

Same as me , I use doorstops on top of bankers around the edge if i do a S&C screed - which hasn't been for a while - .Without the doorstop , I think if you tamp your bankers in a bit more , making them a bit more solid and try not to lean on the straight edge , also try taking a bit less off each pull.

when you're doing a sand and cement screed Dave, what do you use to screed off?, I've accrued a few various lengths of scaffold tubing over the years (straight!) and I find them superb for screeding off.
