DRYWOOD OPTISEALER is an opaque semi-matt, water-borne industrial primer for interior and exterior wooden joinery and other wood constructions.

DRYWOOD Optisealer SG can be applied by Airmix (Aircoat) or airless by hand or in automatic spraying equipment. DRYWOODOptisealer SG will typically be applied on hardwood, which for non-durable hardwood has been pretreated with a Wood Preservative. Exterior durability of coating systems including DRYWOOD Optisealer SG is typically documented according to BRL0814/0817.

DRYWOOD OPTISEALER has a good penetration into the wood and good sealing properties on various wood species such as merbau and sapupira. The product has nice filling and leveling properties.

Surface preparation
