Polyurethane
Varnishes 
Polyurethane
provides the toughest finish available with excellent corrosion,
chemical, scratch and wear resistance. Use indoors or outdoors to
provide maximum, long-term protection. Varnish dries clear and is
non-yellowing. Jo Sonja's Acrylic Polyurethane Varnishes are available
in three different sheens: Gloss, Satin and Matte.
Directions
- A coat of Clear Glaze Medium is recommended over a newly painted
piece to seal the surface for ease in varnish application.
- Gently shake before use.
- Jo Sonja's Gloss Varnish may separate or "crawl" if first coat
is
 applied
too heavily. If this occurs, continue brushing with a criss-cross
motion until varnish adheres. Varnish can be thinned slightly
with Flow Medium.
- Apply with a large soft bristle brush, working on small manageable
areas. Apply a very thin film of varnish using a criss cross motion,
then smoothing the strokes in the direction of the wood grain.
You can over-brush, touch up and rework the varnish until it dries.
- Allow at least 1 hour before application of second coat. If
previous coat has dried more than 24 hours, light sanding will
ensure adhesion of additional varnish layers.
- For best results varnish in a cool, draft free area.
- For an alcohol resistant finish, apply 4-5 coats of varnish
and allow to cure before use.
- Maximum durability is reached after 2 weeks cure time under
normal conditions.
- DO NOT use over oil based products or antiquing finishes
