ROOF - LIQ

 ROOF - LIQ is a special waterproofing compound of synthetic base with additional water repellent for prevention of leakage of water through any type of roof structure. Treatment with ROOF - LIQ will prevent any leakage for a number of years, unless fresh cracks develop due to various other physical factors. This can, however, be made good immediately, by applying the compound in the affected area. ROOF - LIQ must be applied in two coats, the second coat after the first is thoroughly dry .(Preferably on the next day.) 1kg. per 1.12 sq. meters. ?If the compound is dry due to partial evaporation of the solvent caused by leakage from the container or due to prevailing heat or other factors, if brushing is found difficult: add about 120 - 180ml. of kerosene per kg. of the material and thoroughly stir. This will facilitate easy and smooth brushing. It is available in 5 & 25 kg. containers. 6 months if kept in unopened condition.

SEALCOTE

 A single pack clear acrylic resin based water repellent coating. Suitable for concrete blocks, bricks, stone cement plaster to seal moisture movement completely and permanently.

Surface preparation is very vital before the application of this product. Surface should be free from running water and it should be dry. Application by spray or brush.

Coverage: 3 to 5 sq. mete per kg. Consumption depends on surface texture. It is available in 5, 20 and 100 kg. containers. 1 year if kept in unopened condition

ARMOURCRETE

 An acrylic based polymer modified cementitious coating system. The ARMOURCRETE polymer, when mixed with cement, will provide a mortar with better adhesive properties, impact resistance, flexural strength and thin section fragility, when compared to ordinary cement mortar. It is used with cement to form polymer modified cementitious coating (PMCC). In addition, if used with varying amounts of silica/quartz sand and produces PMC brush topping, PMC filler and PMC mortar. All the above materials are extensively used for waterproofing and strengthening of existing external surface to prevent ingress of water. To produce a PMC mix slurry, brush topping or mortar, required quantity of ARMOURCRETE is to be mixed with proper amount of cement. The PMC material is placed on the surface to be treated after wetting the surface to a saturation, without any free moisture. The curing of the PMC material is only nominal and is required for a maximum of 3 days, starting one day after application. For PMC slurry for 1 coat : use ARMOURCRETE -0.25 kg, Cement ~ 0.5 kg For PMC slurry for 2 coats : use ARMOURCRETE -04 kg, Cement. 0.8 kg PMC brush topping 1.5 mm/sq. meter thick ; ARMOURCRETE -0.67 kg, Cement. 1.3 kg fine silica Sand = 1.3 kg For PMC filter & mortar, the mix ratio can be approximately as follows ARMOURCRETE -1 kg, Cement -2 kg, Graded Sand = 5.6 kg For other uses as PMC filter and mortar, please consult SWC specification. It is available in l, 5 & 25 kg. containers. 1 year if kept in unopened condition.

MARINECOAT

 It is a single component water based liquid, which has to be mixed with portland cement and fine silica sand in the desired proportion to produce a pasty material that will bond well with mixed steel, galvanized steel and iron. Provides corrosion resisting coatings to steel structures in sea or fresh water - salt spray environment. Suitable for bridges desks, ship docks, ballast tank for ships, steel water mains, pipings and other above ground and underground tanks. When exposed to traffic, it can be used under wet condition. Correct surface preparation is important for the performance of the coating. The surface to be treated should be properly cleaned to remove all deleterious materials. After mixing the components in the paddle type mixer at site, the resulting creamy slurry of thick paint consistency can be applied with the roller, brooms, brushes or air operated sprays to build up the desired thickness. Air cure for about 3 days - for normal cases and water cure for about 3 days when the surface treated is subjected to continuous water exposure. One cubic meter of MARINECOAT requires the following:
MARINECOAT-446kg.
Portland cement - 858 kg
Fine Silica sand - 858 kg.
For a 2mm thickness of coating, the requirement will be about 4 kg of the three component marine coating.
The generally applicable thickness thickness ranges from 0.8 to 1.0 mm. The corresponding requirement can be worked out from the 2mm thickness value. 		It is available in 5, 25 containers. 1 year if kept in unopened condition.
