Monarch Bituminous Waterproofing Coating For Sandwich Constructions,Waterproofing Coatings,Waterproofing Paint MonoProof BWP is a ready mixed coating, brush applied bituminous, black, lead- free, acid, alkali, water and chloride resistant that cures by reaction with atmospheric moisture to form a tough but flexible waterproofing membrane. They also meet the requirements for coatings suitable for use on surfaces in contact with potable water. MonoProof BWP are based on raw materials which are amongst the most water and water-vapor resistant surface coating materials available. They are also resistant to a wide range of chemical attack. Also to protect the concrete against effects of chlorinated water, and to inhibit algae growth and facilitate easier cleaning. The excellent chemical resistance of MonoProof BWP makes it particularly suitable for sub-structure applications in areas where chemical contaminants and aggressive ground water conditions prevail. Specially selected bitumens are blended to produce various grades, each designed to provide the best possible protective coating for its practical purpose. MonoProof BWP incorporates fibers which give body to the film and act as reinforcement in the coating, eliminating cracking and crazing under conditions of thermal movement. Note : In common with all bituminous and tar based coatings, and many other organic materials, MonoProof BWP are susceptible to prolonged exposure to ultraviolet light and are not, therefore, recommended for use in situations where they will be exposed to direct daylight. They are however, ideally suited for use in sandwich constructions, or as surface coatings in enclosed tanks or structures, or below ground, where their durability is well proven.
