  • The product specification is appropriate for your intended requirements.
  • The basecoat is fully dried.
  • The surface finish of the basecoat is suitable for overcoating.

Surface Preparation

Only apply TS815 Topseal onto a fully dried System S Basecoat; normally this will be 3-5 days after basecoat application. Dependant upon site conditions, heavy basecoat loadings may require longer drying periods prior to the application of TS615 Topseal. The surface of the dried basecoat must be clean, free from condensation, grease or other contamination.
