Preparation
Prepare the surface before commencing the application, and remove any contaminants that can hinder the adhesion of this product; this includes dirt, dust, oil, grease and similar impurities. This product achieves complete curing by exposure to the moisture in the air. You should slightly moisten the surface to optimise the adhesion; this also causes foam formation, enabling uneven surfaces to bond.
Application
