BMcN 11 Posted January 12 I am looking to tile two thirds of my downstairs. I am looking for some advice on decoupling and which adhesives to use. The screed is cemfloor (cement based flowing screed). I see Ditra mentioned a lot. Is there a massive advantage to it over something like this? Also, are they suitable to cross from one screed section, over the 4inch block and onto next screen section? I would prefer to not have a joint as one will be in the family room open plan area. Next what adhesive both below then on top of the decoupling? (tiles will likely be 600mm porcelain). Share this post Link to post Share on other sites
wozza 78 Posted January 13 We have Cemfloor screed - we used Tilemaster Setaflex adhesive. We also used Ditra matting and we have 1200 x 1200mm porcelain tiles. We fitted Genesis expansion joints in each door way and also across one section of the floor as it is longer than 8 meters. I cannot comment on the matting that you have linked - we chose Ditra as it has a proven track record. We also used the perfect level master tile leveling system.

BMcN 11 Posted January 13 Thanks for the reply. Did you prime the floor? And Tilemaster Setaflex below ditra then for tiles too? Share this post Link to post Share on other sites
wozza 78 Posted January 13 Yes we used a primer on the floor, not sure which now, and yes the Setaflex above and below the Ditra. Share this post Link to post Share on other sites
CC45 272 Posted January 13 DITRA used upstairs on boarded floors - seems good to me. Not an area you want to make a cockup on really... Share this post Link to post Share on other sites
