Instructions for use

Remove grease and other dirt from the surface with Kiilto Cleaner 303. If necessary, sand the surfaces after cleaning, remove the dust and then clean the surface with Kiilto Cleaner 303 once more. Wipe surfaces with a clean, lint-free cloth wetted with primer. Allow to dry for 10-30 minutes before applying the adhesive. It is recommended to apply the adhesive soon after priming. If there are several days between the priming and the adhesive application, if dust or other dirt has accumulated on the surface, the surface pre-treatment must be repeated.
