PREVIOUSLY FINISHED SURFACES
For best adhesion, surfaces must be clean, dry, and free of wax,
grease, oil, shellac, lacquer, mildew, and polishes. Remove wax
with wax stripper, shellac with a paint stripper, and mildew
with a solution of up to 10% household bleach and tap water.
Old finishes in poor condition must be removed. Sand to obtain
a smooth surface. Do not use steel wool as rust may develop
after finish has been applied. Remove all sanding dust using a
vacuum or cloth dampened with mineral spirits.
STAINED OR PAINTED WOOD
Follow manufacturer’s direction for application of stain or
paint. Make certain surface is thoroughly dry before applying
Varathane Diamond Spar Urethane. Refer to manufacturer’s
label for dry times. For best results, use Varathane Premium
Wood Stains.
UNFINISHED SURFACE PREPARATION
Sand smooth using 120-150 grit sandpaper and remove all
sanding dust using a rag dampened with mineral spirits, or
vacuum. If a filler or putty is used, make sure that it does not
contain wax and allow for enough time to dry thoroughly.
APPLICATION TIPS
Product appears milky when wet but dries to a crystal clear
finish. Use adequate ventilation at all times. Do not apply in
direct sunlight. Apply only when the air and surface
temperatures are above 55°F, and below 90°F. Use care when
applying over white or pastel paints or stains as discoloration
may occur. To prevent bubbles in the finish, do not over-brush,
shake, or apply with a roller. Test Varathane Diamond Spar
Urethane in an inconspicuous area before beginning. Testing is
particularly important when applying over paints or stains as
the appearance of these products may change slightly when a
water-based finish is applied.
APPLICATION (Aerosol)

2.) Use a drop cloth or newspapers to protect surrounding
areas from spray mist
3.) Spray light mist coats, holding can 10-12 inches from
surface. Move can with a smooth sweeping motion to
avoid runs and sags. Several light coats give a better
finish than one heavy coat.
