Tiles sliding!!!!

[ninjatiler]

Hi guys, am helping a friend tile a bathroom the walls are not the best, anyway using bal grip the tiles are sliding and fall off above the window, the walls are painted, would i be right in saying that the paint needs to be sanded down and the walls primed and would you use a batten cheers..

[Fekin]

Yep, paint needs to be sanded and primed, and if your still having problems with the tiles sliding then yeah use battons.

i agree with fekin i think bal super grip is crap but that is just my opinion

[Branty]

What size are the tiles nija?

We also scored through the old paint in a diamond pattern as well as sanding.

Was just about to ask that myself

The tiles are 250x300 and yes i agree bal grip is rubbish gunna sand the walls tomorrow and use battons anyway...which primer should i use and do you sand all the paint off

[creative]

Use any brand tiling-specific primer you can get locally, but not PVA. It's not necessary to remove all paint... just a fair bit of it!

I have half a tub of bal primer will that do cheers again

Yes it will do, I would mix it 1 to 4 with water after removing most of the paint. If you tile onto painted surfaces, you risk the tiles falling off at some point. If you imagine paint drying as a layer, and we've all seen paint peeling off walls, and so the tile will be stuck only to this layer.

I would remove 90% of the paint. Easy way to remove paint is to soak the painted area with water (using a sponge), 2 or 3 times, and with a hand scraper and a sharp blade it should fly off.

Make sure to leave the wall to dry out before priming.

If it is BAL Bond SBR, then 1:4 is fine.
If it is BAL APD or BAL primer, then 1:1 if you are using a ready mix.
If you are using a cement based adhesive, then 2 coats of APD or BAL Primer neat, or 2 coats of SBR diluted 1:2.
