DAVIES® MORTAFLEX® is a modified acrylic water-based polymer developed to improve the performance of cement mortar or concrete. The resulting cement compound exhibits excellent adhesion, water resistance and mechanical strength not found in ordinary cement-water mixture. DAVIES® MORTAFLEX® transforms cement into a tough but flexible coating perfect for waterproofing. It is highly resistant to water penetration on landscape flat decks and wind driven rain on exterior walls.

SURFACE PREPARATION

Surface should be clean, dry, free from oil, grease, dust, dirt, loose materials and other contaminants. Remove dirt, dust, loose or excess grit or mortar with stiff brush and clean surface by high pressure water hosing. The loosening or fallen of concrete have to be removed and the large holes, cracks should be repaired first. All structural cracks must be repaired prior to waterproofing application. Use the required sealants and structural bonding agents.
