Can you tile straight onto both exterior plywood and plasterboard?

Is any PVA glue required at all, and if so, at what mixture rate? Is for the bath area of the bathroom…

Mix Water with PVA at 2:1.

Leave to dry and carry on.

Don’t forget to PVA the edges, as they must be sealed.

    yes but I recommend coating the area with watered down PVA glue and let dry before continuing.

    Physically …yes, but it wouldnt be the best way, especially onto the plasterboard as if you ever decide to re tile in years to come removing the tiles will destroy the plasterboard, but if its for quickness & you wont be there in years to come then its the simplest way. I would use PVA at rate of 2 or 3 to 1

    I seen Holmes On Holmes and he used a roll out sub flooring system deal that made a base for the tile thin set to stick to and It is suppose to keep the floor at an even temp. so that it doesn’t crack on one side or the other, because the other guy used different flooring in 3 different areas under the tile.

    Sure, if you want to do it all over again in a few years.

    You can tile onto plasterboard straight away. But with the ply either use an adhesive to go straight on to wood or water down a 50-50 mix of pva and roller that on and allow to dry until next day.

    Contrary to some comments – DO NOT USE PVA!

    Do this and you will literally be tiling onto a very thin layer of PVA.

    The problem with PVA is that it becomes ‘live’ if it gets damp. So for example – you have a tiny gap in the grouting on your floor tiles – after a few months water will find it’s way there – PVA becomes live – with repeated movement, adhesive will fail – grout cracks – start again.

    Don’t take my word for this, I’m an amateur, but have a look at the Tiler’s forum on the screwfix website (Link below).

    Type "PVA" into the search function and start reading the posts – you’ll very quickly learn that PVA is a no-no.

    In fact, if you’re about to start tiling the bathroom – spend a few hours reading various posts, the forum was an absolute godsend to me when I recently refurbished my bathroom.

    Good luck.
