Morcemdry PU is a two-component semi-elastic cladding of polyurethane free from solvents. It provides polyurethane waterproof elastic claddings of great thickness and great resistance to abrasion and acids / diluted alkali.
Surfaces to be treated should be clean, without grease and dust in order to obtain an adequate adhesion. Use Implarest PU as primer.
