How to paint wood
Wood has a natural beauty that is usually enhanced by the use of transparent coatings called varnishes. Wood has to be protected from damage by water, sunlight and abrasion. There are various products available for different end-uses:
- Fired Earth Varnish Gloss finish available in standard colours. Contains UV light absorbers and linseed oil for superior wood protection.
- Fired Earth Preservative Suede finish available in standard colours UV resistant penetrating oil-based wood preservative. Water repellent with insecticidal properties. A carefully selected blend of resin, oil, wax preservative it gives deep down protection into the timber.
- Solid colouruse Fired Earth Non-Drip Enamel medium sheen acrylic with excellent exterior durability.
This is the critical part of any painting project: poor preparation is the principal cause of coating failure. The object of surface preparation is to provide a strong surface before applying any paint. The necessary steps are as follows:
- Sand the surface using successively finer abrasive papers. Sand in the direction of the grain. The use of a sanding sealer will improve the quality of the resultant finish.
- Remove dust from the surface by wiping with a damp (not wet) lint-free cloth.
- Clear Varnishes: Apply selected varnish to the surface, leave to cure overnight, and then apply a second coat. Brushing is the preferred method. Further coats may be required over porous soft wood (e.g. SA pine).
- Solid colour topcoats (enamels): Apply a quality Wood Primer by brush or roller. Leave to cure overnight then lightly sand the surface before applying Fired Earth Universal Undercoat, then lightly sand the undercoat and dust off. Apply the selected enamel topcoat and leave to cure overnight. Apply a second coat of topcoat for optimum appearance.
- Solid colour topcoats (acrylics): Apply a quality wood Primer by brush or roller. Leave to cure overnight then lightly sand the surface before applying selected acrylic topcoat and leave to cure for at least 4 hours. Apply a second coat of topcoat for optimum appearance.
Other important information
- NEVER apply paint if rain is forecast, or expected, during the day of application
- Apply paint after 8h00 (summer) or 10h00 (winter) to ensure the surface is not too cold or damp.
- It is recommended that the paint is applied before 12h00 to avoid excessive temperatures and to allow the paint to harden sufficiently before any afternoon rain may occur.
- Always use the SAME batch number for touch-up work. This reduces colour/sheen variations, which otherwise may be visible on the surface being painted.
