Before applying Flex 310 Polyurethane, it is important to ensure that the surfaces are clean and grease free. Many surface contaminants (e.g. dirt or dust) can be cleaned with Weicon Surface Cleaner. For heavily soiled surfaces, Weicon Cleaner Spray S may be more suitable. Old paint or adhesive residue may be removed using Weicon Sealant and Adhesive Remover.
If bonding to smooth surfaces it may be advisable to slightly roughen these materials as this will significantly improve the adhesive power achieved.
