Bitumen Primer

Whatsapp Order

Bitumen Primer is a high-performance, solvent-based or water-based coating designed to prepare and seal surfaces before the application of bituminous waterproofing or roofing systems. It enhances adhesion by binding dust, reducing surface porosity, and creating a tacky base layer for membranes, felts, and asphalt-based applications. Bitumen Primer is quick-drying, highly penetrative, and applicable to a wide variety of substrates including concrete, masonry, metal, and wood. It plays a critical role in extending the durability and effectiveness of waterproofing systems in construction and industrial environments.

Description

Bitumen Primer

Primary Uses

Laboratory Applications

  • Used in research labs for testing adhesion and compatibility of waterproofing systems. 
  • Facilitates evaluation of primer efficacy under simulated environmental conditions. 
  • Applied in quality assurance labs for bituminous product development and testing protocols. 
  • Supports surface preparation during prototype testing of coating systems. 

Secondary Uses

Industrial Applications

  • Applied on concrete roofs, walls, and foundations before bitumen membrane installation. 
  • Used in tanking and dampproofing for underground structures and retaining walls. 
  • Serves as a primer coat in road and bridge construction before bituminous overlays. 
  • Prepares metal surfaces to prevent corrosion and improve membrane bonding. 
  • Applied in pipe coating systems for corrosion protection and adhesion enhancement. 
  • Used in waterproofing projects for terraces, basements, and water tanks. 
  • Supports industrial storage structures by sealing joints and surfaces prior to final coating.
