Adhesive for anticrack matting

Adrian mcc · Jun 5, 2019

hi all, I have never used an anti crack matting before but hav asked the customer to use one as I’m tiling over underfloor heating overlay boards, I have primed in prim grip from tile master. He has bought this orange matting looks like schluter but think it’s a copy I was just wondering what’s the best way to install it ie adhesive he has bought this adhesive does it need to be a standard set adhesive

Standard set or rapid set it doesn't matter . I'm putting some down later today I'm using a slow set as it gives me more working time and I can mix a whole bag no worries and im not tiling until tomorrow.

Cheers think I will swap it all for standard hate rushing like a mad man can it be stuck down with rapid thanks for replying

Oh and 8 or 6mm to stick the mat

I know some recommend 6mm but I think Schluter and dural both recommend 4 mm

Is it printed down the entire length in the centre in black with Schluter Ditra on it?

I’m halfway through laying 40sqm of durabase and it’s recomended to use 4mm

I agree. They do. Find out what you are using and confirm with manufacture if unsure

6mm for mats for me, 4mm is hard to get coverage

What are the overlay boards your tiling to and how are you dealing with them ?

I tend to use a 6mm also & I use one of these for my matting also for a better adhesion

Always 4mm for me. I use a Karl Dahm underlayment roller. 6mm notch can bunch adhesive when rollered

I alway use rapid with membranes too. The bond strength will be there next day

You can put more weight on with durabase than ditra. I go 30kg and 20kg.

When I first used Schluter Ditra years ago(with Schluter's own 4mm mosaic trowel) I did query with Schluter that I wasn't able to get anywhere near 100% contact. There reply was, basically ......''not to worry,it's not supposed to be''

With a cavity mat if you use to much adhesive and it gets into the structure of the mat it loses it effectiveness as a movement membrane

Also as vapour management

Hi they are the overlay boards from poly pipe.the mat is the orange mat from tile easy, I primed and stuck down with a 4mm notched trowel peeled bits back to check for coverage all is good. Used rapid set to lay it then standard to lay tiles. The mat is really good defo going to use a mat again. Customer isn’t overjoyed he has to fork out another 400£ but prep is everything I say

Is £10 a meter dear for a anticrack mat

Bopster · Jun 6, 2019

I charge around £5 m2 for matting, you can lay easy , really easy 50m2 in a day on your Todd .
And in a small room, just use rapid and tile same day just adds a few hours onto your day
