Tiling onto Plywood

[rustylt2]

Have a job to do where the old kitchen wall tiles have been removed and some of the plaster has come away too. I was thinking the quickest wasy would be to screw 6mm plywood to the wall and tile onto that - nice even surface. What is the best primer to use before tiling? Tiles are just normal 100mm ceramic. Any other preperation required also?

 

[DHTiling]

Use backerboards not plywood ..much better to tile to...

How is it any quicker than drywall addy?

You'd have to prime the back of the plasterboard with acrylic for a kick off.

no you dont hes right drew and most tilers will have tile adhesive but not dry wall adhesive

 

[Droopy]

Yes you do.
The rapid set is cement based, so the board has to be sealed with acrylic to reduce any chance of a reaction between that and the gypsum, just like you need to seal the front when you tile with cement based addy.

It is also at least 3 times the price, takes longer to go off, and is harder to use than dri-wall addy is.

I honestly can't see a single benefit from using that over dri-wall.

its paper your sticking to not plaster

Same with the front , and you seal that. Don't you?:huh2:

 

[Perry]

no need to seal..Mark.

 

[Droopy]

no i dont never have never will :lol: help

Even when using a cement based adhesive to fix a large format porc' or heavy travertine?

Chances are that it'll be fine, but why risk it for a few minutes and a couple of pounds?


You should look at using Nicobond Unique when tiling onto plaster, or plasterboard. It's gypsum based, so no need to worry about any reactions.
It also sets full in 1 hour.

 

[DHTiling]

drywall adhesive is cement based and so is rapidset adhesive....you don't prime plaster boards to dot & dab plaster boards with drywall or rapidset......you prime the face side only to slow the setting down if tiling but it is not a necessity.....

Gypsum is sandwiched, it dosn't make any contact with any adhesive.(.except for edges)...so how can it react.......no chemical mix-up...gaz

 

[Perry]

have to be quick then have used there rapid took 3 days to dry not to impressed not all adhesive manufactures recommend to prime plasterboard and also lots of little tricks you find out over the years which are not recommended but work :yes:

Dri-wall adhesive is gypsum based.

I know all that.
But it is common practice to seal the face before using a cement based addy, it is up here at least, so why not the back too?

What about the price difference?
Around 16-20 for 20kg of rapid, or £6 for 25kg of dri-wall.

 

[Perry]

slip of the finger normally my problem :lol: and 4 hours to go and find it
