How to use Varathane Oil Based Polyurethane Spray?
Ideal conditions to use
Use adequate ventilation at all times. Do not apply in direct sunlight. Apply at temperatures between 55-90°F (13-32°C) and the relative humidity is below 85%. Be careful when applying over white or pastel paints or stains as discoloration may occur.
Previously Finished Surfaces – To ensure proper adhesion, surfaces must be clean, dry and free of old finishes, dust, dirt, oils or foreign matter. Remove shellac with a paint stripper and mildew with a solution up to 10% household bleach and tap water. Old finishes in poor condition must be removed. Sand the surface using 150-220 grit sandpaper to obtain a smooth surface. Remove all sanding dust using a vacuum or a cloth dampened with mineral spirits.
Unfinished Surface Preparation - Sand smooth using 150-200 grit sandpaper and remove all sanding dust with a vacuum or a cloth dampened with mineral spirits. If a filler or putty is used, make sure that it does not contain wax and allow enough time for it to dry thoroughly.
Stained Or Painted Wood - Follow manufacturer’s directions for application of stain or paint. Make certain the surface is thoroughly dry before applying Varathane Polyurethane Spray. Refer to the manufacturer’s label for dry times.
Application / Spraying
Shake the can vigorously before and during use. Use a drop cloth or newspapers to protect surrounding areas from spray mist. Apply light mist coats, holding can 10-12” from the surface and spray with a smooth sweeping motion to avoid runs and sags. Several light coats provides for a better finish than one heavy coat. Allow the finish to dry 4 hours, then recoat. Dries to the touch in 2 hours and can be recoated after 2 hours. Let dry overnight before use. To ensure a smooth finish, sand lightly between coats using 220 grit sandpaper. For maximum durability, a minimum of 3 coats are recommended.
