porcelain wall tile adhesive

[beesley121]

Hi guys,

Im about to lay 600x300 porcelain wall tiles to a plasterboard/plastered background

I have a tub of ready mixed tile adhesive that says it can be used on porcelain tiles, will i be ok to use this?

also, im laying the same tie (different colour) on the floor. The floor is concrete, do I use a flexible adhesive or other?

thanx in advance

Don't use tubbed gear on that size tile, use a cement powdered adhesive.....

as above, a single part flexible adhesive is what you should be using. A tubbed adhesive relies on air to dry it out, on large format tiles this won't happen.

also, you mention plastered walls, this could be problematic as your porcelain tiles will probably be too heavy for this type of substrate.

As the guys have mentioned above, use a cement based adhesive, not tubbed. Use a single part flexible.

Your plasterboard wall will carry up to 32kg pm2. Depending on the thickness of your porcelain, you may be ok. A 10mm Porcelain with adhesive and grout will weigh 28.09kg pm2. A 12mm Porcelain with adhesive and grout will weigh exactly 32.00kg pm2. If your plasterboard has a plaster skim, this is greatly reduced down to 20kg pm2.

Again, with your floor, used cement based adhesive will be required. Check that your floor is flat, deflection & dust free. Use an SBR primer before tiling.
