Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
What weight are the tiles per m2?
Is it plaster over board or over block/brick? Is it a wet or dry area? What size & weight are your tiles per sq/m? This dictates the type of adhesive you need to use which determines if you need to prime or, indeed, if it will actually support the weight of your tiles!

The walls are all baton and board. the shower area is cement board. the tiles we havent bought yet.
I assume stone tiles will be heavier then ? I think we will be going for some type of stone.

Your better off not plastering if tiling; unplastered boards have a max tile weight of 32kg/sqm, plastering drops this to just 20 kg/sqm & these weights include up to 4 kgs/sqm for the adhesive & grout. You will have to watch the weight, natural stone & anything more than 8mm thick could exceed 16 kg/sqm & the addy/grout weight may put you OTT. There is undoubtedly a safety margin & my guess would be around 10% but that’s just my opinion. So around 18 kg/sqm is going to be your absolute maximum over plaster & even that may be chancing it.
With tiles much over 250 x 250mm, you should use powder cement addy not tub ready mix or you could have adhesion problems & the addy may take weeks to set or the tiles may even fall off. If using cement addy over plaster/plasterboard, you must acrylic prime to avoid a possible reaction between the gypsum in plaster & the cement in the addy. Good to see you used cement backer board in the wet areas, you should have no weight problems with those &, depending on the make, will take up to 50 kg/sqm or more; you don’t need to prime those for powder addy. Never use standard PVA for tiling.
Use only quality trade tiling products of the correct type for your tiles & tile base - BAL, Webber, Granfix, Mapei (but not the stuff in BnQ) etc. avoid Unibomb own brand or DIY products which are mostly crap.
You need a flexible addy & grout & be careful with natural stone & some porcelain, it can be porous & some need sealing BEFORE laying/grouting to avoid staining. Use Silicone down the corners of your shower area & between the top of the tray/wall not grout.
