How to use

Ensure the wooden surface is clean, dry and free from dust, grease and loose fibers before application. Stir the primer gently without creating excessive foam.

Allow the primer to dry fully according to ambient temperature and humidity before sanding lightly if necessary and applying the chosen paint or varnish. Do not apply over wet or frosted surfaces and avoid application at very low temperatures.

Usage recommendations

For best results, test adhesion and compatibility with the selected topcoat on a small inconspicuous area. When priming exterior wood, ensure previous coatings are sound and that the substrate is well-ventilated during drying. Follow safety instructions on the product label and provide adequate ventilation during application and drying.
