Hi, on the shower walls and the floor.

Thanks

Read the packaging it will give an indication on your mixes, water and powder ratios

As above. The addy will have all the instructions on the bag. If you are unsure, mix the entire bag with the specified amount of water/solution. Just be careful with the setting times (also stated on the bag).

This depends upon the adhesive you are using..

Most cement based adhesives will state no more than a 6mm final bed.. this is what is achieved after you have bedded youre tile in place and some thicker bedding to 10mm or so in located area's..

If you think you need thicker on the floor area's then you can use a thick bed adhesive..some go upto 22mm but if the correct prep is done then you should not need that depth.

I tend to use Mapei kera flex maxi on walls...and this can bed to 12mm... so better if walls are slightly out and cross bonding tiles to achieve that flat look.

On larger format on the floor , you can also use a Flexi PTB to achive that solid bed fix..

And as the members have mentioned above..Always read the instructions if unsure of a products uses..

I have a pool coping tile that we need to concrete around. We plan to co tune the tiles over the concrete. The tile is 20mm porcelain. How far below the coping tile should we set the concrete to make it easy for the tile?
