Antibacterial primer “BALZAM” is designed for waterproofing wooden products and metal structures, as well as for surface preparation (concrete slabs, cement-sand screeds, etc.) before applying torch-applied roofing and waterproofing materials.
When applied, the primer penetrates deeply into the surface, strengthens and binds it, ensuring strong adhesion between the base and the waterproofing layer. It also prevents fungal mold growth, reduces corrosion, and extends the service life of materials. Supplied in liquid form.

Technical specifications:

• Adhesion strength at 20°C: at least 0.1 MPa

• Heat resistance: up to 75°C

• Brittleness temperature: −30°C

• Water absorption (24 hours): not more than 0.5%

• Drying time: 72 hours
