MORTER-PRIMER

BITUMINOUS PRIMER

📝 Description

MORTER-PRIMER is a liquid bitumen with a proper viscosity, designed for waterproofing and moisture-proofing. It is produced by compounding bitumen with a rapid-volatile solvent. It is applied to surfaces like concrete, cement mortar, and steel pipe. It functions as an under-laying liquid, forming a membrane on the ground to make the waterproofing layer adhere strongly.

📍 Key Uses

As a prime coat for concrete, smooth asphalt roofs, and metal surfaces prior to the installation of any MORTER-PLAS membrane.
Under-layer coating in waterproof and moisture-proof construction.
Under-layer coating for anti-corrosion of metal.
Preservation of timber against decay.

Applying the Product

Dry the surface thoroughly.
Completely remove all impurities, such as oil, scale, rust, etc.
Coat the prepared surface with primer using a roller or spray.
