Fairmate Waterguard Liquid Membrane High Performance Waterproofing Membrane

Product Details

h elasticity, ensuring a permanently flexible barrier over a wide range of temperatures. < Thermal stability. < Excellent adhesion. < Can be applied to a range of substrates. < Outstanding resistance to oxidation and brittlement. USES WATERGUARD LIQUID MEMBRANE is a single component high performance waterproofing membrane with high elasticity and low water permeability. WATERGUARD LIQUID MEMBRANE is particularly 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 when protected from exposure to direct sunlight. STANDARD COMPLIANCE WATERGUARD LIQUID MEMBRANE complies to ASTM C 836-84. DESCRIPTION WATERGUARD LIQUID MEMBRANE is a highly elastic tough waterproofing system based on modified bitumens water based co-polymer. WATERGUARD LIQUID MEMBRANE is highly resistant to aggressive soils and soluble salts providing an effective continuous barrier and protection against water bourne damage. WATERGUARD LIQUID MEMBRANE is ideally suited as a vapour/salt barrier to building facades behind granite, marble, stone cladding, and curtain wall elements. PHYSICAL PROPERTIES Colour : Black Form : 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 Base : Water based 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 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 not normally required on good quality, well prepared 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 : WATERGUARD LIQUID MEMBRANE should be applied 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 construction or backfilling works. Any damage may be repaired by spot application. If a water flood test is to be run, the membrane should cure for a minimum of 10 days. Whilst WATERGUARD LIQUID 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. Cleaning : Application equipment should be thoroughly cleaned after use with water. Spillages should be absorbed with sand, vermiculite or similar and be disposed of in accordance with local regulations. PACKING & COVERAGE WATERGUARD LIQUID MEMBRANE is supplied in 20 kg pails. It has a coverage of 1.5 - 2 m² per kg at 1mm WFT. Coverage rate will vary with substrate condition and profile. L
