How To Choose The Right Thinset For Shower Walls
Water Resistance
If the adhesive that you are using isn’t water-resistant, then the tiles setting will fall off within a matter of days. So, water resistance is one of the most crucial factors that you need to consider before purchasing a unit
Since the tiles in the shower constantly remain in contact with water, a high water-resistant thinset will be able to save the base of the walls from dampening, and mold buildup. The capacity of water resistance varies from unit to unit. You should go for one depending on which part of the shower you are using to set the tiles.
Drying Time
The drying time of a thinset refers to how much time it will take for the tiles to be completely set and it also determines how long it will take to become water-resistant.
