Preparing the Shower Base for the Liner
Before installing the shower pan liner, it is crucial to prepare the shower base thoroughly. This involves ensuring that the surface is clean, level, and free of any obstacles or debris.
To begin, remove any existing fixtures or drains from the shower base. Clean the surface thoroughly using a degreaser or bleach solution to remove any dirt, grime, or soap scum. Rinse the area with clean water and allow it to dry completely.
Next, use a level to check the slope of the shower base. The slope should be approximately 1/4 inch per foot towards the drain to allow for proper drainage. If the slope is insufficient, use a mud bed to create a sloping surface. Alternatively, if the slope is excessive, you may need to remove some of the base material to create a more gradual slope.
Once the slope is correct, inspect the surface for any imperfections or obstacles. Fill any small gaps or cracks with thin-set mortar or silicone caulk. Remove any sharp edges or protrusions that could puncture the liner.
To ensure a secure bond between the liner and the shower base, apply a thin layer of thin-set mortar over the surface. Spread the mortar evenly using a trowel, making sure to work it into any corners or crevices. Allow the mortar to dry completely before proceeding with the liner installation.
