WATERGUARD LIQUID MEMBRANE : Single Component Liquid Applied Elastomeric Waterproofing Membrane Coating
FAIRMATE has wide range of products and our products are broadly classified as Concrete Admixture, Waterproofing System, Engineering Grouts, Industrial Flooring System, Surface Treatment, Concrete Repairs, Pre-packed Concrete and Mortar, Protective Coating, Poly Sulphide Sealants, Highway Repairs, and Fire Protection systems.
FAIRMATE has introduced an innovative solution in its Waterproofing range called WATERGUARD LIQUID MEMBRANE which is suitable for a wide range of applications including wet areas, foundations, basements, terraces, retaining walls, bridge abutments, planters, inverted roofs and remedial repairs to felt, asphalt, concrete, fibreous cement or other roof structures.
Description:
WATERGUARD LIQUID MEMBRANE is a ready to use single component bitumen based high performance coating that dries to a tough, impermeable waterproof membrane. It is ideally suited as a vapour / salt barrier to building facades behind granite, marble, stone cladding, and curtain wall elements.Being a water-based and environment-friendly material, it enables good adhesion even when the surface is moist. It provides elasticity, ensuring a permanently flexible barrier over a wide range of temperatures. As it is a cold applied material, hence does not require heating or thinning. It has outstanding resistance to oxidation UV Light & brittlement and provides a seamless insulation layer. Moreover, no special skilled person is required for its application.
Recommended Uses:
- Useful as protective coating on concrete and brick foundations, retaining walls, timber, metals, etc.
- Provides a sandwich membrane in new construction and surface treatment on existing slabs.
- Provides a key for plaster on difficult surfaces.
- For waterproofing and protection of structure, concrete, columns, and beams.
- Used for the external insulation of foundations, underground constructions, and basements etc.
- Used for insulating water leakages in closed damp environments such as bathrooms, kitchens, and toilets, etc.
Physical Properties:
Colour : BlackForm : One component
Specific Gravity : 1.1
Tensile Strength : 2.5 N/mm2
(ASTM D412)
Elongation at Break : 900%
(ASTM D412)
Cure time : 24 hours approx.
Crack bridging : Up to 2mm
Application Instructions :
Surface preparation: All substrates must be sound, clean, dry, smooth and free from protrusions, voids, honey-combs and high spots. Presence of curing agents, paint and oil will impair adhesion. Moss and lichen must be removed and area treated with proprietary fungicidal wash to kill spores and inhibit further growth. Following treatment, wash the area thoroughly with clean water and allow drying. Fillets must be provided at corners or sharp angles using 4:1 sand and cement mortar modified with a good quality bonding agent – FAIRCRETE SB (L).
Priming : Priming is required only on bad substrates.
Cracks : All shrinkage and non- structural cracks must be treated with not less than 1.5mm coating of WATERGUARD LIQUID MEMBRANE extending 75mm either side of the crack. Allow to cure overnight prior to general application.
Application : The membrane should be applied directly by brush to obtain a continuous unbroken film. Two coats are required with the second coat applied at right angles after the first coat has cured.
WATERGUARD LIQUID MEMBRANE must be protected from mechanical damage during subsequent construc- tion or backfilling works. Any damage may be repaired by spot application. If a water flood test is to be run, the membrane should be cured for minimum 10 days. Whilst this membrane is resistant to frost, adhesion will be impaired if applied to frosted substrates. Application should be avoided if substrate temperatures are below 5ºC or rain is imminent.
