detailed information

BORNIT® Roof Varnish is a brush and spray application material, which is based upon bitumen. It has been tested as per DIN 18 195.
Certificated by the Dresden Testing Institute for Construction Materials.

BORNIT® Roof Varnish penetrates deep into the base and is therefore optimal for regenerating weathered bitumen roof coverings.
BORNIT® Roof Varnish is also used as a protective layer directly after the roof covering has been laid. BORNIT® Roof Varnish is suitable for application onto concrete, bricks and plaster as a protective layer against ground dampness.

• good coverage during the first coat
