Description

Rockbond Flexible (APFC) Membrane (RB FM) is a 2 part elastomeric Anti-carbonation, Protective Flexible Coating. The dry pack, Rockbond Flexible Dry Membrane Pack (RBFM DP) is a blend of special cement powders, graded sands and compatible admixtures. When the powder is mixed with Rockbond Flexible Latex (RB FL), a coating is produced which is extremely adhesive, flexible and waterproof. The membrane waterproofs and protects concrete against carbonation, acid gases and chemical attack. The material is supplied in 3kg/2 litre or 15kg/10 litre packs and has a shelf life of 2 year.

Special Properties

• 2mm of Flexible Membrane provides anti-carbonation protection to concrete equivalent to 50mm of good quality concrete!
• Available in white, and also in a range of colours.
• Easy to mix and apply by trowel, float, spatula, brush or spray.
• Adheres strongly to all construction materials: cement, mortar, concrete, masonry, brick, stone, steel, wood, plastic and glass.
• Microporous, waterproof and weatherproof.
• Elastic: will flex in sympathy with moving or cracked concrete, wood, brick or render.
• Remains flexible at temperatures down to -40ºC.
• Permanent, resilient, and durable, and resistant to ultraviolet (UV) radiation.
• Protects concrete against frost attack, carbonation, sulphation and acid gases.
• Water “soluble” - the material and equipment can be washed and cleaned with water.
• High yielding, economical, non flammable, non toxic, user friendly and safe to use.

Uses

• For use as an Anti-carbonation Protective, Flexible Coating (APFC) to cement and concrete.
• Whenever stress, thermal or moisture movement is a problem at a crack, joint or within a concrete structure.
• Tanking, roofing, weatherproofing and waterproofing applications.
• The filling, sealing and waterproofing of cracks, joints, gaps and seals.
• To protect reinforced concrete structures against freeze/thaw cycles, de-icing salts and corrosion of steel.
• To protect concrete in extreme climatic conditions, high altitude and in severe weather.
• Elastic requirements during cold weather or low temperature situations.
• To protect concrete where chemical attack is prevalent such as in marine locations, chemical works, food processing factories, sewers and farms.
• As a flexible adhesive to bond concrete, tiles, bricks and blocks to concrete, steel and wood.?
