Jo Sonja Decoupage Varnish is a heavy-bodied version of Gloss Varnish for artists who wish to finish their projects with a thick, lacquer-like coating. It has been specially formulated for decoupage artists to hide the cut edges of paper. Applying 8 to 10 coats of Decoupage Varnish is equivalent to 35 to 40 coats of other, thinner varnishes. Decoupage Varnish dries to a thick, glossy finish that does not yellow over time. It may be used both indoors and outdoors to provide maximum long-term protection and, when cured, is corrosion, chemical, scratch and wear resistant.
All Purpose Sealer or Clear Glaze Medium may be used for adhesion of decoupage paper to the surface.
For large areas, a coat of All Purpose Sealer applied to the back of the paper and allowed to dry may decrease bubbles during application. Repeat on paper front. Allow to dry.
Bubbles may be avoided if paper is brushed lightly with water to moisten prior to application. Apply All Purpose Sealer thinned with Flow Medium 1:1 or Clear Glaze Medium to the surface and the back of the paper.
Begin to press the paper against the surface from the centre out to work out air bubbles. A Soft cloth and a circular motion are recommended.
Lock down by gently using a brayer or wallpaper roller.
Directions for applying Decoupage Varnish
A coat of Clear Glaze Medium is recommended as a barrier coat prior to varnishing.
Gently shake the varnish and apply undiluted to the surface. If thinning is necessary for the first coats, add a few drops of Flow Medium, Retarder or distilled water to thin slightly. Do not over-dilute.
Apply Decoupage Varnish in criss-cross motion using a soft but firm brush suitable to surface size.
Smooth by brushing final strokes in the direction of the wood grain. Avoid overlaps or drips along the edge.
Allow to air dry a minimum of an hour before applying additional coats. Drying time depends on the number of coats applied, climate and humidity. A hair dryer may be used to speed the surface drying. Avoid excessive heat, which could cause crazing.
A maximum of 8 to 10 coats will be required to hide the edges of the paper.
Allow varnished item to cure a minimum of 2 weeks before use. Cure time varies due to climate and humidity.
Note: not recommended for use over oil based paint or oil based antiquing finishes.
