Preparation
- Remove all traces of old finishes, dirt, oil, wax and grease. These may have impregnated the surface and can cause failure.
- Sand in direction of the grain to provide a key.
- Thoroughly clean after sanding.
Bare or New Wood
- Fill any gaps or minor imperfections in the wood with a suitable wood filler
- Lightly sand bare or new wood to provide a key
- Take care to remove all traces of sanding dust prior to varnishing
- Degrease wooden surfaces with a lint-free cloth dampened with Methylated Spirit if required
Previously Painted Wood
- Newly painted wood should first be sanded to provide a key
- Heavy Duty Extreme Varnish should not be applied over uncured oil-based paint as this may cause discoloration
- Older painted wood, where the paint itself may fail, should be stripped using a hot air gun or a suitable paint stripper, then sanded and cleaned prior to coating with varnish
- When applied over an emulsion / latex paint, it is possible that the varnish could draw certain stains through the paint which were not otherwise visible. In this case a dedicated stain sealer should be used
Application
- Ensure the product is well mixed but do not shake. Apply 3 coats with a synthetic varnish brush.
- On new softwood and porous surfaces, dilute the first coat 10% with water. Lightly sand wood in between applications to remove any raising of the grain.
- For a dead flat finish with high durability and stain resistance, apply 2 coats of satin followed by 1 coat of dead flat.
- To achieve full UV protection, apply 3 coats of satin before a final coat of dead flat. Instructions in the technical data sheet must be followed.
Caution
- Appearance may vary according to the colour and type of wood and the number of coats.
- Do not continuously submerge in water.
- Test for compatibility before application.
Cleaning Equipment
Application equipment can be cleaned using soap and water before the varnish dries. Wipe any excess off surfaces with a damp, lint-free cloth. Any dried deposits will need a paint stripper to remove them.
Storage
Protect from extremes of temperature during storage and application.
