Waterproofing materials
P-665 Special-grade Non-after-tack Black Rubberized Asphalt
This product which is derived through copolymerization of macromolecular resin, rubber, asphalt, and elastic aggregates is a waterproofing material with excellent tensility. In contrast to generic rubberized asphalt (“black glue”) products, it does not exhibit shortcomings such as after-tack during application and bubble formation.
【Properties】
Water-based, non-toxic, no after tack, air permeable, applicable to wet surfaces
Outstanding tenacity and adhesion
【Uses】
Waterproofing projects for roofs, bathrooms, external basement walls, and atrium gardens
【Method】
- Remove all objects, dust, and loose material from the construction surface.
- Apply 1-2 coats of P-930 Ultra-strong Oil-based Curing Agent to the whole surface to cure pulverized layers.
- Allow a drying time of around 30 minutes, and then reinforce the coating on cracks, corners, and pipe edges by applying two coats with a brush or roller
- Apply 2-3 coats of the rubberized asphalt diluted by adding 0-10% water to the whole surface (the thickness of each layer should not exceed 1mm). Don’t apply the next layer until the previous layer is completely dry.
- To achieve optimized crack resistance capabilities on roofs and atriums, attach glass fiber mesh between two layers of the rubberized asphalt.
【Reminders】
- In case of excessive sand or powder formation on construction surfaces, curing through 1-2 coats of P-930 Ultra-strong Oil-based Curing Agent prior to application of P-665 is recommended (construction surfaces must be completely dry when the agent is applied).
- Due to the color bleeding properties of the utilized raw materials, the product should not be applied to slanted roofs and light-colored silicone on window frames.
