Oil Paintings on Canvas

Removing grime and yellowing varnishes reveal details in a painting. We also can restretch a painting or make repairs to the canvas or the paint. A full structural stabilization might involve lining techniques.

CRAQUELURE

Craquelure comes in two types: drying cracks, which are cracks in the paint layer caused by gradual drying; and aging cracks, which run through all layers, from the paint to the canvas.

REVERSAL

Reversal of prior restorations often involves removing wax resin and glue linings and re-lining or re-weaving with non-penetrating synthetic adhesives and materials.

SURFACE GRIME

Surface Grime is an accumulation of airborne pollutants that dull the surface.

TEARS

Oxidation, exposure to atmospheric oxygen, causes the canvas to lose its elasticity and become brittle.

TENTING, LIFTING &
CUPPING

Tenting, lifting & cupping of the ground and paint layers can be caused by excessive exposure to moisture, heat and improper storage.

VARNISH

Oxidation also causes varnish to slowly darken.
