The repair mass may only be applied for an ambient temperature between 15°C and 32°C. The processing time is about 21 minutes for an ambient temperature of 21°C.
6 Thoroughly mix together the basic material and hardener in the correct proportions.
The correct mixing ratio of the basis material and hardener is 3:1 by volume or 4.3:1 by weight. The repair mass should not contain any air pockets from mixing. It must be like putty and lump-free and have a constant color.

7 Apply repair mass over the cleaned sealing surfaces (arrow) thinly and evenly using a spatula.
A number of layers may have to be applied in order to achieve the required thickness of the repair mass.
8 Wet spatula with water and wipe smooth the repair mass.
Allow the repair mass to harden at an ambient temperature of
about 21°C for about 4 hours.
The hardening time will be longer at a low interior temperature. Never warm using an open flame.
9 Remove excess repair mass. Smoothen the repair points as required.
10 Remove adhesive tape from the sealing surface of the cylinder crankcase and thoroughly clean the adhesive locations.
11 Pull out stop plug from the coolant holes in the cylinder crankcase.
