BOYSEN®® Plexibond™ B‑7760 Cementitious Waterproofing System
BOYSEN®® Plexibond™ is a specially formulated acrylic polymer designed for compounding with Portland cement. The resulting mixture possesses excellent adhesion, water resistance, and flexibility even on thin section applications. Its use eliminates water seepage. This makes it ideal for positive side waterproofing roof decks and firewalls.
SURFACE AND MATERIAL PREPARATION
Remove all existing paint film manually, mechanically or by using BOYSEN®® Paint and Varnish Remover B‑141, as necessary. Wash surfaces clean and completely remove chemical residue. Let it dry.
In case of mildew infestation, treat with a bleach solution (1:3, laundry bleach to water, respectively) by swabbing or brushing. To ensure proper treatment, let stand for 24 hours before cleaning off residue. Let dry.
Surface to be painted should be clean and dry, free from oil, grease, dust, dirt, contaminants, and all loose grit and mortar.
Dampen concrete surfaces first with water before applying Plexibond mix to avoid abrupt drying and cracking of the applied modified cement, especially under hot and sunny conditions.
Slowly mix 6.5-7.5 kilograms of cement to 4-Liters of BOYSEN®® Plexibond™ while constantly stirring to prevent lumping.
Pass the mixture through a fine strainer to sift out lumpy materials. Ensure intimate mixing, stirring as often as possible to avoid settling. Keep mixture proportion constant for a uniform texture.
Mix only enough material to prevent waste. Workability of Plexibond mixture is 30 minutes, while the potlife is 2 hours.
