Description: VINMASTIC® is produced from high-quality bitumen, modified with polymer, rubber, and special agents. It is a dark, hot-applied mastic that meets the requirements of ASTM D1190, ASTM D6690, and TCVN 9974.

Application Area:

Sealing expansion joints and cracks in concrete and asphalt pavements.
Sealing joints and cracks in concrete slab structures such as roofs, industrial floors, etc.
Repairing cracks in asphalt pavements.
Waterproofing and protecting concrete and reinforced concrete.

Advantages:

Bonds well with cement concrete.
Unites well with asphalt concrete.
High resilience.
Easy to apply.
High economic efficiency.

Installation Instructions:

Surface Preparation:

Substrate surface must be solid and free from dirt, oil, grease, and curing compounds.
Substrate surface must be dry.

Execution:

VINMASTIC® is melted at 190 ± 5oC in special equipment or a conventional pot.
Do not heat VINMASTIC® beyond 210oC.
After VINMASTIC® is melted, it should be agitated or recirculated. Do not blend with other materials.
Seal melted VINMASTIC® into joints/cracks using a pump or pouring pot.

Note:
