Once dry, IMPER becomes a flexible, durable waterproof membrane. The IMPER membrane is easy to apply. It can be spread with a paintbrush then the membrane can be added upon the latex. 

IMPER is also an excellent anti-fracture membrane which allows to overlap existing stable fractures while avoiding for them to transpose onto the tile work.
