Adhesive on a wooden substrate. - TilersForums.com

[Andy Allen]

I normally use bal single part fast flex on wooden substrates over boarded with Hardie.
I need an adhesive that's as flexible, but more rapid setting than the 5 hours fast flex takes to dry...
Any suggestions would be greatly appreciated...

Mapei's ultralight S2 quick is rapid, but in this weather probably the same.
Have you tried mixing with warm water Andy? That can speed it up.

Tilemaster Ultimate S2 sets pretty quick.

It's every bit as strong but not as rubbery. I have my doubts that it's as "deformable" as Fastflex.

But would you tile a over boarded floor where ultimate wouldn't be adequate?
I know I wouldn't

Hence my question....
I've always gone with the belt and braces approach to a wooden substrate, using, imo the most flexible adhesive I know.

Some adhesive is sold as flexible, but imo only flexible enough for UFH...

I thought a S2 adhesive wasn't more flexible the a S1 it had a stronger bond strength. They are very different from a Fastflex which is more rubbery/flexible.

S1 has always served me well with timber floors. If I need an s2 my go to is now rocatex. They've a standard set one which I'll be trying shortly
