LENi All Purpose Sealer is a surface primer to promote paint adhesion and reduce paint absorption into surfaces. Use this instead of Gesso to seal items not requiring ‘tooth’ or opaque colour. Directions: Apply directly to clean, dry surface. When dry, sand lightly before painting. Alternatively, mix 1:1 part of paint and sealer and apply. Sand when dry before painting a second coat without sealer. Ensure metal or tin is clean, rust free and lightly sanded. Allow 24 hours to harden before painting. This product does not prevent rusting. Clean up with cool soapy water. Always test on sample area before applying to entire project.
