Preparation
Clean all areas to remove moss, lichen and debris by brushing or power washing and remove surface water and any contamination such as oil or grease and allow to dry. Treat area with fungicidal wash to prevent further fungal/algal growth. Suitably repair any defects in the substrate prior to coating. RainStop can be applied without primer on most roof surfaces.
It is advised a test area is always carried out, particularly on any previously coated areas. For porous and metal surfaces use Primer for best results. To the dry and cleaned surface, apply Rainstop by brush or squeegee at an approximate coverage rate of 1kg-2kg/m².
Application
Application temperature range: 5℃ - 25℃, using a brush or squeegee.
