I have been to see a job today. Somebody has screeded a york stone floor which has now blown. Would an Ardex surface DPM 1C be sufficient with Ardex NA screed. Any advice would be appreciated. Phil
Yeah, I was planning on screeding the York Stone, DPM and then final screed to recieve flooring . Phil
Should be ok then. I have used it alot the last couple of years. The thicker you put it on the higher RH% you can go over.
I did an Ardex training day and the guy said ' use a normal 2 mm adhesive spreading trowel ' . It looks like A.T.A ( remember that ! ) when it goes down, but the seration ? drops and forms a suitable covering of D.P.M. Phil
2mm is a standard carpet adhesive size (could be B1?) and is bigger than A2. If you use A2 you won't get enough on the floor to protect upto 97%RH
God, I remember doing a WH Smith in Cambridge. The basement must have been about 800 sq. m all in tile on ata. I must have spread about 400 sq before I had to come up for air, and chuck my guts up. Never got any ventilation in there, nasty job
You need a thicker notch if you want it to cover 97RH% not sure of the thinkness size but I use the standard notch ( a3 I think ) for putting it on normal an a deeper notch if high moisture.
f3 ahhhhhh when i 1st started that was the only glue you could get, for sticking everything, carpet, vinyl, etc etc etc well thats what the boss said!
Ha! Same here laid a few thousand metres of altro with f3. Until that new fangled f44 stuff came out.
