What surfaces to prime

[Anna Rack]

They sound like fun!?! How do you go about tiling on boards with screws and washers sticking up? Especially mosaics!?! Sounds like an absolute nightmare!

First time I've used these boards but it seems the screws and washers would compress into the surface when tightened so would end up flush.

Oh I see.. You should post up some pics, it'd be interesting to see it coming together 😉

Back to the orginal question, I guess I don't need to prime anything unless the surface is dry/dusty? Or is it best as a matter of course anyway?

So you've never used the foam backing boards? There seem to be endless posts on the forum recommending using them over plywood.

It's all a learning curve for me... you try searching the internet to do something 'properly' and end up wishing you'd never started the job. Anyway I seem to be following the path most pros seem to suggest, only question mark is whether I should have used the thicker board.


Will get some pics up once things get moving.

The washer pulls into the board, nothing is proud if done right.

Here are my efforts so far, apart from a few tiles with a bit of lippage I am pretty pleased with the result. I guess a beige grout would be the way to go?

Looks nice. Limestone grout would be my choice 😉

6mm? I'm presuming this a newly poor-build green chipboard? The real thing to look out for here is STABILITY and MOVEMENT. Place a glass of water at one end of the room and jump up and down on that green chipboard. If it makes the water shake, then don't tile this floor! Simple as that. If it doesn't, then lace it with min 9mm (I meant 25 mm) screwed down every 300mm centres and get it tiled!
