Langridge Retouch Varnish

Langridge Retouch Varnish is made by dissolving Paraloid B67 resin in Artists White Spirit to make a liquid. Brush or spray applied over paintings, the solvent will evaporate, leaving a thin, even coat of the resin. Langridge Retouch Varnish may be applied to touch dry oil paintings. Artists oil colours dry by absorbing oxygen. For full drying this process generally takes between 3-6 months although it can take longer with extremely thick paint films (5mm or thicker). When a painting has a dry surface film (touch dry) it may be protected with the application of a temporary varnish that will allow the passage of oxygen to the oil paint and continue the successful full drying of the painting.

• A final picture varnish applied before the 3-6 month drying period will prevent thorough oxygen absorption leading to potential oil paint film failure due to erratic drying.
