How To Apply Sadolin Extra Durable Polyurethane Varnish
Sadolin Polyurethane Extra Durable Varnish should be applied in full flowing coats, laying off in the direction of the grain, ensuring all surfaces and end grains are fully coated.
For best results use a good quality, synthetic fibre bristle brush specifically designed for the application of water borne products.
Following surface preparation in accordance with the manufacturers recommendations, finish with 3 full coats of Sadolin Polyurethane Extra Durable Varnish allowing a minimum of 2 hours drying between coats.
Avoid over brushing as this will cause brush marks and result in a poor quality finish.
Carefully denib between coats using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicone carbide abrasive paper in the direction of the grain.
Do not break through the surface coating. Remove all dust.
All subsequent coatings should be applied as soon as possible after the previous coat has fully dried.
