TERRACE / ROOF WATERPROOFING BASED ON MEMBRANE COATING SYSTEM
Kamroof GFM is designed to protect surface of the building terrace & roof from water & weathering effect.
It is developed for complex / critical applications where conventional waterproofing / weatherproofing products cannot be used or applied. In these areas waterproofing products like polymer admixtures, repellent, adhesives, general purpose coating and sealants do not perform effectively for long time. In such applications the product should withstand heat, UV effects, expansion & contraction, gravity settlements, shrinkage and ageing effects. The product should be long lasting & should remain elastomeric and active permanently.
Substrates material : Cementitious substrates, asbestos cement, insulation materials, metal substrates, wood & plywood, bricks & stones, slates & tiles, plastics, bituminous coatings, paints, mastics, asphalt & felt.
Concrete/plastered roofs & walls, corrugated sheets, terrace gardens, parapets & chhajjas, drain sections, expansion joints, ventilation outlets, J hooks & screw overlaps, lighting fixture mountings, roofing junctions.
Residential buildings, commercial buildings, Manufacturing units, malls, warehouses, nuclear power structures, theatres.
1. Sealcoat: Acrylic based elastomeric high performance coating emulsion. It is single component and ready to use formulation with quick drying properties. It is water repellent with toughness to arrest leakage and seepage of water. It protects the surface of UV radiation. It has got excellent adhesion to substrate and elongation of 200%. It has very good impact strength and withstands extreme temperature.
GFM (Glass fibre matt ) is supplied by Owens Corning India Ltd. and it is made of glass fibre chopped strands. It is incorporated in this system because if the treated surface has foot traffic then plastic coating alone may not withstand the ware and tare. On the surface where no foot traffic incurs the GFM need not be applied. However it is strongly recommended to use GFM for long lasting effectiveness and toughness.
Elastofalt is a thixotropic cold applied polymer modified bituminous coating. It has very high adhesion strength. It protects the surface from water & weathering effects. The elongation is 900% and forms very good film on the substrate. It can be applied on any surface except ceramic tiles & metal.
Elastoprime is a primer or bond coat for surfaces like tiles or china mosaic chips. Elastofalt or Sealcoat do not easily adhere to the substrate like tiles or china mosaic chips. On such substrate it is essential to give bond coat of Elastoprime, which is actually Elastofalt diluted with water in the ratio 1:1.
Surface should be clean & dry. All the surface lying water, mould growths, moss or other vegetation, loose debris etc. should be removed prior to application. Ensure that surface is free from visible dampness, dust. Dirt and other form of contamination should be removed prior to application.
The surface to be treated should be in good condition, like plaster, concrete should not be deteriorated or debonded. The paint should not be in peeled off condition. The metal surfaces should not be rusted or torn.
The wood and plywood should not be grained or expanded. The asbestos sheets and brick should not be in cracked condition. The tiles and plastic surfaces should not be in cracked or broken condition.
Kamroof GFM coatings can be applied by brush or spray. Given below application procedure of standard system
