Description

A quick drying black bitumen priming solution designed to penetrate and seal a variety of porous surfaces.


Features and benefits:

  • EshaPrimer creates a base seal and improves the adhesion of bituminous waterproofing solutions.
  • EshaPrimer is a mixture consisting high quality bitumen’s and hydrocarbon solvents.
  • Directions of application: The substrate must be clean and dry, structurally sound and free from laitance, oils, dirt, moss, lichen and loose materials. If applied to an existing roofing membrane the surface must be quite smooth. Apply by brush or roller ensuring the primer is well applied into the surface. Apply a thin coat and avoid pooling. Allow to dry thoroughly before over coating. Ensure ventilation is sufficient. EshaPrimer requires between 1 and 4 hours to completely dry. EshaPrimer must be completely dry before applying the bitumen membrane. For additional protection two layers can be used.
  • Consumption: The consumption depends on the surface, typically: 0.1 L/m² on metal/ smooth bituminous roofing. 0.2 L/m² on concrete. Ensure that EshaPrimer is evenly applied and does not pond beneath the new membrane.
  • Delivery conditions: Delivery form 25 litre cans, 16 cans shrink-wrapped on a euro-pallet (80 x 120).
  • Storage according to CRP 15-guideline: Store in a fire safe place and keep away from heat, sparks, open flames and other ignition sources ignition. In the original closed package EshaPrimer will be in good condition for at least one year.
