Observe the “4-property rule”
To guarantee reliable adhesion of KEMPEROL, always observe the “4-properties rule” for the substrate; meaning it must demonstrate four properties.
Another prerequisite is prior cleaning and possible roughening of all surfaces using KEMCO MEK. Bitumen coated with PE film or bitumen rubber surfaces should first be carefully flamed with a torch to achieve good adhesion.
