600x600 Porcelain on anhydride wet ufh - TilersForums.com

[steve.g1977]

Hello, have got 65 sq/m of 600x600 porcelain to lay on a anhydride screed,floor has been down for 4 years,so should be dry!having read a good few threads on this forum(been very helpful)this is my plan,
1.sand floor to remove any laitence
2.prime using TM prime plus
3.fix TM anti-fracture matting using 6mm trowel and anhyfix adhesive
4.fix tiles using Genesis tiger trowel and TM standard setaflex
5.grout with TM grout 3000
Is this the right way to go?
Any help/advice would be appreciated,thanks in advance
Steve

You don't need matting , or should i say its not nessessery .
It won't do any harm but i wouldnt bother.
just tile it

Thanks for the quick reply Wilder, Only reason I'm thinking of going with matting is I've got a couple of cracks in the screed, they are straight above where the ufh clip channels are ,and a couple seem to follow the pipe runs,is this common on this type of screed?also I'm thinking using the matting will let me use setaflex which will give me more open time with adhesive.

Not seen many anyldrite screeds to be honest, ive only seen and tiled one in 30 years!
Went to see it today , 110m2 of porcalain , all different rooms , all tiled up to wall and no skirting looks mint , no cracks ect
Not sure on the cracking to be honest , on your screed , but prob better be safe than sorry though as well with the matting and use it.

How thick is that screed, looks thin and too many cracks in all directions. Is it solid or sound loose.

 

[steve.g1977]

Screed is 55mm and solid, been down near on 4 years

Use the mat but fix it with a 4 mm trowel. with a 6mm you'll just be squashing the addy everywhere.
