Make sure the area is clean and that all dirt, dust and grease is removed. Cut off the top of the cartridge, screw on the nozzle and cut the nozzle to the required size. Apply to the area to be filled using a cartridge gun. Smooth the surface with a clean scraper. The material will set faster when warm.

Vitcas® Heat Resistant Filler can be sanded before painting. Certain types of emulsion paint may require the use of a proprietary stabilising primer before application - check with the instructions on the paint.
