Tiling on plasterboard

[geraldthehamster]

Hello

I'm going to be fixing a single row of small ceramic tiles directly to plasterboard. The area is dry. Should I prime the plasterboard first, and if so, with what?

Many thanks
Richard

Hi Richard. I'm not a tiler, but have done plenty of DIY. Yes, I would prime the area with PVA. the reason being that plasterboard is very porous and will suck the moisture straight out of your adhesive.

The alternative is to use a grab adhesive, rather than tile adhesive. I have used 'Pink Grip' before to lay some mosaic tiles on a hardboard backing and they are still there, fine, you can still grout as normal.

PVA is unsuitable for tiling on.

I never knew that !! I just PVA'd my concrete floor in my kitchen and retiled it !!!

Why is it not suitable ? What would you suggest instead of PVA ?

Remember, the chap is only tiling ONE row of tiles.

Tile primer.

PVA reactivates when it gets wet. I tend to use SBR Primer

Of course. I never thought of that. Cheers. I'll bear it in mind in future.

Gerald - Ignore my PVA advice !!! Just use "Pink Grip" instead !!!! It will be far cheaper than tile primer and tile adhesive.

Hello all, and thanks for the advice. It's not going to get wet. As it happens I just tiled directly to plasterboard with bog-standard wall-tile adhesive.
