Lexel’s® seal is 19 times clearer than silicone and can handle up to 400% joint movement. That means Lexel® will bend and flex with your home and will stay clear the entire time. Lexel® won’t stain or yellow even when it faces harsh UV exposure, abrasive cleaners, or scouring pads during routine cleaning and maintenance. Lexel is waterproof, immediately upon application and never freezes, which means it can be applied even in the wettest or coldest of conditions.
If dirt or oils are present on the substrate, wash with any household cleaner, rinse to remove and allow to thoroughly dry. Remove any old caulk, especially silicone or silicone residue. Use a silicone remover. Insert backer rod into joints deeper than 1/2” to provide for proper sealant depth and a stronger, longer lasting seal.
