Product Application
Langridge Oil Primer may need further dilution for ease of brushing out. If needed, add artist’s solvent to Oil Primer in proportions up to 1:2 or until a thin cream consistency is obtained. It is important not to apply Langridge Oil Primer too thick as the resulting film may be too fat with potential for hairline cracking or lacking in proper tooth.
Langridge recommends the application of two coats for a complete prime and for maximum brightness.
Before applying an oil primer, the support must be ‘sized’ with Rabbit Skin Glue or thinned acrylic or archival PVA to reduce absorbancy.
If over absorbant, the linseed oil in the primer will soak into the substrate leading to an underbound prime coat and embrittlement of the canvas substrate due to acidification by linssed oil.
Painting with oils may commence once touch dry however, as the the curing time is extended the primer will reduce in absorbency when applying succeeding paints. For best results Langridge recommends a minimum of 4 weeks.
