Best Adhesive for Quartz Tiles on Concrete Floor

You should not have used pva try and get as much of this back of the floor ,then prime with sbr 50/50 with water.You then would be better to use a two part flexable as some quartz tiles can warp,but the biggest mistake you have made is applying pva it just forms a coating on the surface.

Aaaaaaaahhhhhhh not sure why you have coated a concrete floor in pva, perhaps to keep the dust down, pva becomes slightly live when wetted up, so any moisture below your tiles will loosen the pva and the bond will be weakened. It's always good to use SBR as a bond, the flooring adhesive should be polymer modified to aid and the underside of the Quartz tiles should be primed with SBR to allow the adhesive to grip the SBR whilst the SBR has adhered onto the Quartz tile.

Hi, I know that the best adhesive to use is from mapei( keraquick & latex plus).this is rapid set adhesive, but if you're looking for slow set you could get mapei P10 and isolastic.basically latex plus and isolastic comes in bottles.it is a liquid that makes the adhesive so strong that you can't imagine. P10 is harder to find usually it is used for glass moasaic. And grout is easy,just go for epoxy grout.mapey or keracol

You should never use PVA as a primer, will need removing. (see previous post I have made on why). If its a new floor it needs to be completely cured and dry. Adhesive should be a bottle + bag (powder). Never use water and powder adhesive mix, the tile will not stick. Many makes to choose from, mapei, bal, but Weber is my choice. Remember to butter the back of the tile as well. Grout, I would use a smooth one such as mapei or ardex. Depending on the manufacturer of you quartz it my need sealing. Your tiler should know all this unless you are using a painter and decorated, carpenter, plumber or multi trade to do the job, who would probably not know the correct materials and fixing method. Hope this helps Julian

''Thin set mortar'' usually made by CUSTOM.. to set with on back of tile, grout will be either sanded or non sanded depending on the thickness of your joint
