How should All Tech Insulation coatings and sealants be prepared for overcoating (re-coating) after initial cure (first few hours) of the All Tech Insulation coatings and sealants?
Prior to overcoating All Tech Insulation coatings and sealants make sure it is basically clean. For the first several hours after All Tech Insulation coatings and sealants has gelled it may be suitable for overcoating without further preparation. If the base coat material has been in place for longer than 3 hours there could be minor problems with inter-coat adhesion (as the product is fully cured). To assure inter-coat bond apply liberal amounts of an aggressive solvent such as acetone or MEK to All Tech Insulation coatings and sealants and allow it to evaporate completely. This will re-tack the base coat and allow proper adhesion of the follow-on overcoat.
