Best adhesive for putting 600 x 600 tiles onto mr board in bathroom and how would you go about installing? Dabs on back and pressed into wall or combed onto wall fit. Asking for a friend
Do not use ready mixed in tub. Use adhesive in bags.Best adhesive for putting 600 x 600 tiles onto mr board in bathroom and how would you go about installing? Dabs on back and pressed into wall or combed onto wall fit. Asking for a friend
8mm notched trowel on the wall, tight coat on the back of the tile. Have you got the tiles already? Are they naturals or porcelain? If dark use grey flexy if light use white flexy. Use a levelling system, will make life abit easier.Best adhesive for putting 600 x 600 tiles onto mr board in bathroom and how would you go about installing?

It’s not me doing this btw it really is a mate, he contacted me earlier asking a few questions before he starts
Tiles should be planned on the roomsize, anything less than a 100mm rip with big tiles looks wank. If you’ve got bath, shower, toilet frame and a window. It all needs planning off them before you buy the tiles.600 x 600 is far to big for a small bathroom, will look stupid
The bit about the air pockets is bollox.Some aspects of large-format wall-tiling are covered here:
Sal DiBlasi has some informative vids:
As others have already said, use powdered adhesive (also note that ready-mixed adhesive is downright unsuitable for large-format tiles as there is a risk it may never cure fully). Be warned that many powdered adhesives go off quickly, so it's best not to mix huge batches, and it's best to clean your whisk immediately after mixing, just as you would with skim. BAL and Mapei are both good quality.
Although it's great for plastering, NEVER use PVA to prime surfaces for tiling purposes!
Spread a tight thin film of (bagged powder) tile adhesive on the back of the tile, and a combed coat applied to the wall. Note that it is good practice to comb the adhesive entirely in one direction (I mean for the final comb-stroke) which means the lines travel across the shortest dimension of the tile.
For example, if you were applying a 600 wide x 300 high tile to the wall, then all your tile adhesive would be applied to the wall so that the combed lines run down the wall. The reason for this is so that you minimise the risk of trapped air pockets in the adhesive when you squish the tile onto the wall, and also so that shorter lines of combed peaks offer less resistance as you squish the tile sideways, back&forth.
The bit about the air pockets is bollox.
The reason for combing horizontally is so that any water that gets behind the grout will be able to dry out rather than pooling at the bottom of tiling if combed vertically.
You will note tiles fail at bottom of walls/showers for this reason.
I am glad to have added to your knowledge mate.Just going by what I've been told, over the years.
A lot of people just comb on the adhesive in random arcs and swirls, and this CAN potentially trap air when the tile is squished onto the wall.
Makes consistency that much easier if each and every tile beds-down by the same amount, for a consistent amount of physical effort.
