Instructions for use

Mix before use. Apply the adhesive to a cleaned surface using a spatula, and pressing the surfaces to be joined tightly together. If the area to be glued is exposed to direct sunlight, apply the adhesive to the surfaces and allow them stand for approximately 15 minutes before pressing them together. This will allow the solvent in the adhesive to evaporate in a controlled manner, without subjecting the surface of the bitumen product to damage.

To improve adhesion, use Kerabit BIL 20/85 bitumen solution for porous and dusty surfaces. Do not apply adhesive to the very edge of the seam to prevent bleeding out. The need for material is approximately 1l / m2 (the film thickness is approx. 1mm). Surface dry in about five hours at +20 oC, total drying time 1 – 14 days depending on layer thickness. Working temperature +5 ... +50 oC in glueing membranes and shingles. Clean the tools with white spirit or mineral spirit.
