Boiled linseed oil to mix our linseed oil paste to a spreadable paint. Boiled linseed oil is linseed oil that was mixed with a desiccant. It is added to linseed oil pastes to form a spreadable linseed oil paint. For this purpose, it is stirred in equal parts of boiled linseed oil and linseed oil paste including the desiccant. The amount of desiccant varies from colour to colour.
Good boiled linseed oil has a bright clear color. It's a little thicker than cold-pressed linseed oil but without being viscous or too oily.
Boiled linseed oil usually dries within 16-18 hours, in some cases 24 hours.
