MARKPROOF LM 100 is a highly elastic tough waterproofing system based on modified bitumen’s water based co-polymer. MARKPROOF LM 100 is highly resistant to aggressive soils and soluble salts providing an effective continuous barrier and protection against water Bourne damage. MARKPROOF LM 100 is ideally suited as a vapor/salt barrier to building facades behind granite, marble, stone cladding, and curtain wall elements.
FEATURES / ADVANTAGES
- Liquid application, easy to apply.
- No Joints.`
- High build properties ensure rapid application.
- High elasticity, ensuring a permanently flexible barrier over a wide range of temperatures.
- Provides good thermal stability.
- Excellent adhesion.
- Can be applied to a range of substrates.
- Outstanding resistance to oxidation and brittlement.
- For wet areas, foundations, basement, terraces.
- For retaining walls, bridge abutments, planters, inverted roofs.
- For remedial repairs to felt, asphalt, concrete, fibreous cement or other roof structures when protected from exposure to direct sunlight.
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.
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 MARKPROOF LM 100 extending 75mm either side of the crack. Allow to cure overnight prior to general application.
MARKPROOF LM 100 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. MARKPROOF LM 100 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 MARKPROOF LM 100 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.
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.
