Water resistance is one of the key issues of challenge during bathroom construction or renovation period. However, it is essential to understand the entire process of proper construction and the amount to be spent for each phase. Installing a water resistant tile backer is a good idea to keep the bathroom in appropriate condition for longer duration.
Some tile backers require an additional waterproofing system to be placed between the tiles and the tile backer. Generally an extra sheathed membrane is used to accomplish such work.
