Before application of Chemvar, the first coat must be sanded using #280/320 grid stearated paper and free of dust and all contaminants.

Stain systems used under Chemvar should be acid stable.

Catalyze and reduce material as recommended. Apply 3 to 5 wet mils on sanded surface. One extra coat can be applied following a complete cure and a sanding with a #280/320 paper. Maximum film build of the top coat should not exceed 3 mils dry. Maximum film build of the system should not exceed 4 mils dry. Chemvar must not be polluted with oil, varnish or the like and must not be sanded with steel wool between coats. Avoid all contact with metallic surfaces

Finished surface must not be cleaned with ammonia containing products. Always use containers and equipment made of plastic or stainless steel to avoid discoloration of the material due to oxidation.

L'épaisseur du feuil, la porosité du substrat, le mouvement de l'air, la chaleur et l'humidité ont une forte incidence sur les temps de séchage. Les températures sont basées sur la température réelle du panneau de bois. Le temps de séchage peut varier en fonction du temps nécessaire pour que les panneaux de bois atteignent ces températures. La température de durcissement minimale de 18 °C/64 °F doit être maintenue pendant tout le cycle de durcissement afin d'obtenir l'intégrité de revêtement indiquée dans les caractéristiques du produit.
