Areas of application
BORNIT® Dachbit is used as a topcoat in maintaining bituminous and mineral roofing membranes. Not suitable for corrugated bituminous sheets. The roofs must have a pitch of at least 3° (degrees), in order to exclude permanently standing water. In order to improve adhesion, and on absorbent substrates, use BORNIT® Grundbit as a primer.

Type and properties
BORNIT® Dachbit is a solvent-free, plastic-modified protective coating based on a high-quality bitumen emulsion. The product is processed cold and can be brushed, rolled or sprayed using the airless method.

Advantages
  • good adhesion, high opacity as well as resistance to adverse weather conditions
  • free from solvents, hence particularly environmentally friendly
  • suitable for polymer-bitumen sheeting
  • cold workable

Surface
The substrate must be firm, clean and free from separating substances (oils, greases, etc.). It may be slightly moist, but not wet. In case of highly weathered and chalking or absorbent, mineral substrates, prime with BORNIT® Grundbit.

Processing
BORNIT® Dachbit is manufactured ready for processing. Topcoats must be applied undiluted. In that, at least two coats are recommended. The second coat is applied following sufficient initial drying of the first one. Application is undertaken with a coating broom, small or large brush, roller or airless spraying equipment. The processing equipment must be pre-wetted! Clean the respective processing equipment with water immediately after use. Hardened material can be removed with BORNIT® Bitumen Cleaner.
BORNIT® Dachbit must only be applied in dry weather and under no circumstances in case of frost or rain or impending rain, resp.

Consumption
approx. 0.4 l/m² per coat (at least 2 coats)
