Mapei Keraflex Maxi S1

[whyme!]

Hi, I was looking to use Mapei Keraflex Maxi S1 on ply for floor tiles. But i see here
http://www.mapei.com/public/HK/products/74_keraflex_maxi_s1_hk.pdf

It states do not use on wood.
So do i need an alternative adhesive or prime with
MAPEI PRIMER G

you need another adhesive. most manufactures will have something suitable but all should be primed, have a look at Bal or Tilemaster, if theres nothing in the mapei range

 

[whyme!]

I have conflicting views some say it is fine,(Although Keraflex docs say no) also i have been told only prime edges of ply not surface to tile on? Might get bag of Ultra sp, used that before with no issues
Would you suggest some BAL - Bond SBR or Ultra Prime IT FP Flexible Additive & Primer ultra's equivalent

I've always used whichever SBR primer I have had to hand without any issues. Last job on wood I did I used Bal SBR with TA ultimate, no problems so far 6 months on(cue phone ringing ).
Nowadays there's loads of talk about substrates , substrate specific primers, decoupling mats, adhesives etc.
Go back 10 years PVA was the "primer" of choice if used at all and there wasn't anywhere near the choice of adhesives there are now. Not saying the correct procedure shouldn't be followed, failures to some degree have dictated current best practice, but I can tell you of at least one floor which was tiled unprimed straight onto chipboard using 2 part fast-flex that is still solid as a rock, that was done in 2004. I will report back in a month or so's time when it is being pulled up

So bought some Ultra Prime IT FP Flexible Additive & Primer and some Ultra Tile ProFlex SP+ES Standard Set for floor
