Ceramic Tile Adhesive
Using ceramic tile adhesives would be more convenient for most tiling works. The traditional setting method is to lay the tiles directly on a bed of wet portland mortar. It is still used in some situations where you need to create a sloping floor like in a shower stall or the bathroom floor. Here are a few more different ceramic tile adhesive with their uses.
Installing thick bed mortar requires a lot of experience. Some tile setters lay down the mortar bed, smooth it, allow it to cure, and then set the tiles over the bed with a bond coat of cement adhesive. In any case, this method would be better left to the professionals.
There are many types of thinset available in the market. An experienced tile dealer can easily recommend the proper thinset for the job at hand. Probably you would be recommended a cement-based adhesive (mortar) or an organic mastic adhesive. Maybe even an epoxy-based mortar, depending on your application.
These adhesives are actually forms of cement-based mortar, although they should not be confused with the Portland cement mortar used for thick-bed installations. Most of these thinset mortars come in powder form. Some must be mixed with sand before use. Some come as premixed in liquid form. Powdered forms are mixed with water or a liquid latex additive.
These are the most common adhesives, usually sold in powder form and to be mixed with water. They are highly resistant to impact. Dry-set mortar can be cleaned easily with water. Once cured, this mortar is not affected by prolonged contact with water. This is suitable for use in usually wet areas.
A typical installation has a layer about 3/32 inches thick. This material will cover and level small surface irregularities. It is not suitable as a setting bed nor is it suitable for leveling very rough uneven surface.
