Rustins Polyurethane Clear Varnish

Product: Polyurethane Clear Varnish
Type: A high build, air-drying polyurethane. The finish produced is tough, durable and resistant to oil, water and many chemicals.
Intended Use: Bare wood, hardboard, MDF and unsealed cork. Interior use only. For floors, use Rustins Polyurethane Floor Sealer.
Special Features: High abrasion and mechanical impact resistance.
Preparation: The surface must be clean, smooth, sound, dry and free from wax, dust and contaminants. Remove wax by rubbing with White Spirit and a plastic souring pad and wipe away whilst still wet. Cracks may be filled with Rustins Wood filler.
Application: Apply evenly, finishing in the direction of the grain using a good quality brush. The first coat may be thinned with White Spirit (1 part to 8 parts varnish), to act as a sealer when applying to absorbent surfaces.
Coats: 2 coats are usually sufficient on wood. Cork and more absorbent surfaces will require extra coats.
Drying Time: Touch dry in approximately 2-4 hours, depending on the temperature and humidity.
Re-coating Time: Re-coat when the previous coat is hard dry, typically within 4-8 hours depending on the temperature and humidity.
Application Temp: Ideally 15-25°C. Do not use below 10°C or in conditions of high humidity.
Coverage: 14-16 sq.m per litre, 1 coat, depending on the absorbency of the surface.
Maintenance: The varnish will take about 24 hours to dry fully. Afterwards, the surface may be kept clean by wiping with a mild detergent solution when necessary. To restore the gloss, a wax polish may be applied. Worn areas may be re-coated once cleaned, de-waxed and lightly sanded to provide a key.
Compatibility: The varnish may be used over Rustins Wood Dye, Rustins Wood Filler and Rustins Grain filler.
Settlement: STIR WELL BEFORE USE. Satin and Matt finishes may dry glossy if not thoroughly stirred.
Shelf-life/Storage: Many years if stored in original, tightly closed container in cool, dry conditions.
