What flexible floor tile adhesive would you guys use on wooden floors? And would it be the same flexible floor tile adhesive that you would use for underfloor heating for example?

hi admin as you know im new to tile but i only us BAL single part flex on ply i never tile direct to floor boards but thats just me..

hi
i never tile direct to wooden floor , use ditra matting on to the wooden floor,then tile as normal no problems

Bal fast flex was made for this purpose, anyone who has used it will know this. The stuff is amazing. I ve tiled direct to floorboards with no problems. It sticks to almost anything as you find out when you go to wash your trowel and hands when you get home. Pumice stone takes it off skin eventually. I know....wear gloves....

Mapei floor adhesive is designed to tile straight onto wood as it has a pva already through it and it is flexable to allow for movement or heavy traffic

I used to use BAL, but its too pricey for me. I now use Granfix, and that works a treat, and a lot cheaper too. I get it from TILE CHOICE here in the midlands.

I have also used PCI adhesive, and I must say that it is excellent. Only thing is, its like rocking horse sh't to find.

correct me if im wrong but i understand that pva breaks down when subject to water so how does it work in an adhesive that requires water to mix?

Matty, when the adhesive dries, so does the PVA, until it gets wet again....

I might not bee pva exactly but it is some sort of sealant that allows you tile straight on to wood, something to do with polymers but I aint no scientist so aint gonna even try and explain what their job is

It isn't PVA usually when it's a two-part mix. All the contents of the product that cures by hydration, so when it gets wet, will be in the bag, and all the contents of the product that cures by evaporation will be stored in the bottle, and all the products that cure by chemical reaction will be split and some stored in the bottle, some in the bag.

I think.

Be carefull of your grout joints cracking going straight onto the floorboards, the adhesive might be able to take the movement but even the flexi grout has limitations

Good point, so as with the adhesives, if you need to use a two part flexible adhesive, then the chances are you need to use an admix with your grout, if it's a single part flexible grout, you'll be safe with the single part flexible grout too.

great new product out there called no more ply, easy and faster to fit than ply, stick it screw it and tile it it with granfix 1 pert flexy, never use anything else

use no more ply myself great gear, just dont get the glue on your hands
