PRODUCT INTRODUCTION
v HEIBAO JS polymer cement waterproofing coating is two—component waterproof material made of the high-performance synthetic latex modified with a variety of additives and cement and other inorganic powders. It is composed of adhesive solution and powder. It meets requirements of HJ457-2009- a standard of national environmental protection industry.
PRODUCT FEATURE
v Be applied on both dry and wet substrates, performing high adhesion.
v Product specifications: 5kg, 10kg, 15kg, 20kg, 25kg, 50kg.
v No pollution and harmless.
v Work together with other various waterproofing coating and membrane. Live up to different levels waterproofing projects.
v Compared with other similar products, it shows better water resistance and longer waterproof.
CONSTRUCTION REQUIREMENT
v Make sure substrates are smooth, solid and free from honeycomb, pits, dust and greasy dirt, with
v internal/external corners in arc-shaped; before the construction, the defective parts of base course should be repaired.
v If necessary, mix emulsion with water at the weight ratio of 1:1, then brush the mixture on the substrates.
v Add powder into the JS slowly, stirring the mixture evenly until uniform with electric mixer for 5 minutes. Proportioning of waterproofing coating: Weigh materials as emulsion/cement= 1 /(1~1.2)(type I) or 1/(0.9~1.0) (type II ),or 1/2 (type III). If necessary to dilute with water, make sure the water weight can’t exceed the JS’s 10%.
v According to requirements of the engineering design, one-layer primer and two-layer finish or one-layer primer and three -layer finish can be done.
v If the waterproof layer should be enhanced, the non-woven fabrics can be used as matrix for the enhancement processing.
v Brush thinly for several times with scraper evenly. The next brushing should conduct after the prior becomes hard drying.
v Dosage: 2kg/m2 (one-layer primer and two-layer finish); 3kg/m2 (one-payer primer and three/four-layer finish)

APPLICATION RANGE
v JS products can be widely used for waterproof, moistureproof and anti-leakage works of roofs,external walls, kitchens and baths, pools, basement and other buildings.
v JS-III is also applied to the civil building projects.
NOTE
v As a water emulsion coating, the product construction should be done at the temperature higher than 5℃and the anti-frost measures should be taken before curing.
v Seal the rest materials and avoid the powder being damp.
v The storage period of this product in glue solution and powder should be separately 12 months and 6 months.
