How should a Griffin Alkyd painting be varnished?

Varnishes provide a transparent coating which protects your finished painting from general dirt. Picture varnishes are removable, enabling the painting to be cleaned in the future. Varnishes should not be used as mediums for adding to the colour. Although Griffin Alkyd Fast Drying Oil Colour paintings are touch dry in 18-24 hours they should not be varnished until thoroughly dry (at least 3 months). The painting will benefit from being degreased before varnishing. This can be done with Artists’ White Spirit (mineral spirits). Simply wipe over the surface of the picture sparingly and leave to dry overnight. Apply the varnish using a large dry varnishing brush, immerse the brush in the chosen varnish and apply in long steady strokes across the painting surface. To ensure the desired result, test before use. Matt and Satin should be shaken or stirred well before use and should not be used on absorbent or damaged surfaces.
