About Polyvine Exterior Wood Varnish
A waterproof, microporous, UV resistant clear protection for exterior wood. The unique polymer system gives a silky satin finish and highlights the natural grain of the wood. It is suitable for exterior softwood and hardwood timber applications, giving a high level of UV resistance, waterproofing and preservation.
Available in satin and dead flat.
To achieve a fully protected dead flat finish apply 3 coats of satin before a final coat of dead flat.
- UV protective filters
- Resists blistering and cracking
- High solids
- Biocides protect against algae, mildew and fungal attack
- Exterior use
- Nano technology
All surfaces must be clean and free from dust, dirt, oil and contamination. Remove oils/resins from oily hardwoods and resinous softwoods. Treat new wood with a wood preservative to remove all traces of fungus and mould. Ensure pretreatment is compatible and completely dry, before application. Joints, end grain and glazing beads must be completely sealed. Water penetration into the timber will produce unsightly water staining and promote fungal growth beneath the clear varnish. Instructions in the technical data sheet must be followed. Ensure the product is well mixed.
Using a good quality brush, apply evenly using light brush strokes, following the grain of the wood. Keep a wet edge and avoid overlaps. Apply the first coat and allow to dry. On new wood dilute the first coat with 10% water. Sand lightly to obtain the best finish. Apply three coats.
Drying Times and Coverage
Drying time: 1-2 hours
Recoat time: 4 hours
Coverage: 15 square metres per litre
Always apply to a test area before starting work. Care must be taken when applying in high temperature or direct sunlight as this will affect drying time. Do not apply when rain is imminent. Coating life will be reduced on horizontal surfaces and where the coating is in contact with the ground or pooled water.
Protect from extremes of temperature during storage and application.
