Mapei S1 adhesive on ply- Help - TilersForums.com

[jason23]

Hi Folks,
I'm about to do a wee tile job in bathroom. Putting 9mm ply down ( screwed thorughly ) and painting with Excel bond SBR first.

Now tle shop sold me Mapei S1 Keraquick rapidset. i didnt but the extra tub of flexi.

Ive just looked at the Mapie website and it says dont use on wallas and floor prone to extreme flexing or vibration (ie ) wood, fibre cement boards.

Now I'm confused!!!

Can I use this Keraquick s1 on ply or not?

Can anyone advise??

Advise much appreciated, starting work tommorow!

Not on 9mm ply....use latex plus with it....if the ply was within bs standards then it would be fine..

Thanks Dave. OK, I will pop round and get the latex plus.
If I used 12mm would I get away with Keraquick on its own?

How much Latex plus do I mix in?

maybe.....but just use the latex plus and it will be an S2 adhesive then....you mix the latex with the keraquick....no water..

ahh. lucky I asked. Yes, the tile shop assistant didnt even hint at this.

Dave can you recommend a good flexible grout for me in grey?

Do Mapei do grout that utilises this latex plus mixing agent?

Ive had a few grouts crack on me and I'm gonna go flexy from now on.

Mapei ultra colour is pre formulated flexi powder mix..

great. Just got 6 Kg of Latex Plus.

The assistant at the shop informs me to mix 1.5 KG LP with 10 Kg bag of Keraquick.

Do you concur with this mix ratio Dave?

I'm sceptical because she says I should be using 6kg with a 25kg bag! I pointed out that makes no sense at all.

ive also been reading that drying time is v slow with Latex Plus additive? Is this correct? What dry time can I expect?

Thanks for the advise Dave, v much appreciated

OK, I have the definitive answers now. All the myths and nonsense were making me doubt the plain B&W Mapie bible.

Confidence restored.
