Selection Data
Application Data
Generic Type – 100% dewaxed shellac-base sanding sealer.
It is manufactured using a patented process that guarantees
long-term stability and shelf-life. The absence of any wax in
SealCoat makes it compatible with all clear finish topcoats
including oil-base polyurethanes.
Surface Preparation – Surfaces must be clean, dry, and
sound. Remove any wax from surface with mineral spirits.
Sand bare wood as smoothly as possible and remove all
sanding dust. Previously applied wood stains must be
completely dry. Previously applied finishes must be clean and
tightly adhered.
Recommended Uses
Doors, trim, baseboards, paneling, wainscoting
Cabinets, shelves, furniture, interior shutters
Floors, stairs, banisters and spindles
May be used to seal wood turnings, figurines, carvings,
wicker, plaster, and other hobby/craft items
Sanding Sealer - May be used as an undercoat to prepare all
new or previously finished interior wood surfaces for oil-based
and acrylic polyurethanes, varnish and lacquer topcoats.
Pre-Stain Sealer – When used as a pre-stain sealer and wood
conditioner SealCoat evens the porosity of woods such as pine
and fir so stains penetrate evenly. Follow thinning instructions.
Compatible with oil-base, water-base, alcohol and gel stains.
Bond Coat – May be applied as a bond coat over existing clear
finishes to ensure compatibility and adhesion of lacquer and
oil-base polyurethanes.
Barrier Coat – May be applied as a barrier coat to seal odors in
certain types of wood and particleboard.
Not recommended for use as a sealer on exterior surfaces.
Tinting – A wide variety of shades and tones can be
achieved by tinting SealCoat with alcohol-base stain, aniline
dye, or small amounts of universal colorants - up to 2 oz. (60
ml) colorant per gallon. Note that alcohol stains will dilute
viscosity. If using powdered dyes, shake to completely
disperse dye material and let container sit for a few minutes
for bubbles to clear.
Application Requirements – Do not thin product when
using as a sealer or bond/barrier coat. Apply evenly and
consistently and allow to dry 45 minutes before sanding with
120 or finer grit sandpaper. Remove all dust and apply finish
coat. Note: A second coat of sealer will improve the film build
and give added depth to the final finish on porous or open
grain woods such as oak, mahogany, etc. Allow second to dry
1 hour before sanding lightly and applying finish coat.
Application Methods
Brush application: For best results use a natural bristle brush.
Apply a full brush load of sealer to the surface using full, even
strokes, brushing back into the wet material to maintain a wet
edge. Do not over-brush or brush back into material once it
becomes tacky.
Wiping application: Use a lint-free cloth. Pour or brush a liberal
quantity of SealCoat onto the surface and quickly work into
the wood with brush, making sure sealer soaks thoroughly into
any open or end grain. Wipe away any excess with cloth and
stop wiping when surface becomes tacky. For vertical surfaces
pour SealCoat onto cloth and wipe over the wood. If the
wood is stained, a second application may be needed to avoid
sanding through the sealer and the stain.
Spray Application: May be spray applied using conventional,
HVLP systems, or airless. Use a .011 to .013 tip and 800 1000 psi for airless spray application. Follow equipment
manufacturer’s instructions.
Coverage – Approximately 400 to 600 ft2 (37-55 m2) per
gallon. Spread rate may vary depending upon surface porosity
and method of application.
Application Directions
Doors/Trim/Paneling/Cabinets/Furniture - Apply 1 or 2 coats
by wiping, brush, or spray. Allow to dry completely before
sanding with 220 or finer grit between coats to ensure a
smooth finish. If a heavier film build is desired, repeat
application. Remove dust and apply finish.
Floors – Floors should be properly sanded and free of dust,
dirt, or other contaminants. Use a brush or floor finish
applicator and apply in the direction of the grain. Coat two or
three board widths at a time, being sure to keep a wet edge.
Avoid over-applying or over-brushing. Let dry for 45 minutes
before sanding with 120 to 150 grit or finer sandpaper or
screening. Apply second coat if desired or floor finish. Refer to
SealCoat Floor Finish Technical Data Bulletin for more
Pre-Stain Conditioner - SealCoat is ideal for preventing uneven
stain penetration over softwoods such as pine. Thin product
by adding 3 parts alcohol to 2 parts SealCoat. Apply with a
brush or wipe on with a cloth, working with the grain. Do not
over apply or recoat. After 15 minutes, lightly rub surface
with fine synthetic abrasion pad. Apply stain according to
manufacturer’s directions.
Bond Coat – Because it has high adhesion and is compatible
with most other clear finishes, SealCoat may be applied to an
existing finish to protect it from strong solvent coatings such
as lacquer or to ensure adhesion of oil-base polyurethane,
water-base polyurethane, lacquer and other clear finishes over
sterated finishes. Two full coats are required.
Odor Barrier Coat - Shellac-base SealCoat is an effective and
dependable barrier coat for sealing odors in certain types of
woods and particleboard. Two full coats are required for this
Application Conditions
Warmer temperatures will accelerate and colder temperatures
will prolong the dry time of this product. Do not apply when
RH is greater than 85% or when temperature is within 10º of
the dew point. SealCoat is not recommended for use in areas
where surface heat exceeds 160o F (71o F). (Note – Brushing
lacquers may soften sealer film during application. Do not over
brush when applying lacquer or pulling may occur. Always test
apply catalyzed finishes over SealCoat on scrap wood before
Dry time – At 70o F (21o C) the first coat on bare wood will
usually dry to touch in a few minutes and can be sanded and
recoated in about 20 to 30 minutes. Subsequent coats or coats
applied over existing finishes will dry to the touch in 10 to 15
minutes and can be sanded and recoated in about an hour.
Clean up – Wipe up drips and spills with a rag soaked in
denatured alcohol or use a solution of household ammonia
and water. Clean brushes with denatured alcohol or a solution
of 1 part sudsy ammonia and two parts water. To dissolve
product that has dried on application tools, soak tools
overnight in ammonia solution or alcohol. Clean sprayer
equipment according to manufacturer’s directions
