Applications:
1. Metros, tunnels, brides and other substructure.
2. Various types of roofs, canopies and gutters, etc.
3. Indoor flooring, washroom, kitchen, bathroom, garden, flower bed, hot spring tank, swimming pool, sewage disposal plant, tap water cistern, marine site and refrigeration storage house flooring.
4. Treatment to roofs in corrosive environment such as chemical plant, iron and steel works, and power plant. Anti-corrosive treatment to chemical reaction tank, thermal insulation retardation and anti-corrosive treatment to pipe lines and ducts.
5. Crack repairing, filler and sealant to expansion dilatation joint, dividing joint, pile foundation and through-wall bushing.
Construction:
1. The substrate surface must be thoroughly clean, dry and firm. Repair the crack if there is, structure edge angle has to be made round.
2. Stir well and make sure no sediment in the bottom, then mix the coat with 20% (weight).
3. Coating can be finished once on flat surface, in case of running coating in slope surface, apply a thin coat first on the slope, leave the coating in the container 5 to 10 minutes to cure, and then apply the slimy coating on the surface.
4. The coating must be applied over 0 °C centigrade.
5. The second coat can be applied at least 24 hours depending on humidity and temperature when the coat is not sticky to step on.
6. Application rate: 1.5 to 2 Kilogram per square meter with a film of 15~2mm thick.
