EXTRALAC PRIMER

EXTRALAC PRIMER is a bituminous varnish based on special bitumen and selected solvents. Upon application and solvent evaporation, it forms a uniform protective film that helps improve the adhesion of subsequent waterproofing layers.
Its composition makes it suitable for use as a primer prior to the application of bituminous membranes and other bituminous waterproofing systems.

Key advantages

• Excellent adhesion to suitable substrates.
• Creation of a uniform asphalt membrane.
  Resistance to dilute acids and bases.
• Resistance to various corrosive chemical liquids.
• Easy application and quick surface preparation.
• Ideal as a substrate for bituminous waterproofing systems.

Applications

EXTRALAC PRIMER is used for surface preparation in waterproofing projects, enhancing the adhesion and performance of subsequent bituminous materials. It offers a reliable solution for construction projects requiring effective substrate preparation prior to the application of waterproofing systems.

Important note

Although the resulting film is resistant to dilute acids, bases, and certain corrosive chemicals, it is not recommended for applications involving exposure to petroleum-based products, as it lacks resistance to them.

Reliable base for durable waterproofing

Backed by BITULINE’s quality and expertise, EXTRALAC PRIMER offers an effective solution for proper surface preparation, contributing to the creation of high-performance, long-lasting waterproofing systems.
