Liberon Boiled Linseed Oil
Boiled linseed oil is used as a paint binder or as a wood finish on its own. Heating the oil makes it polymerize and oxidize, effectively making it thicker and shortening the drying time. Today most products labeled as "boiled linseed oil" are a combination of raw linseed oil, petroleum-based solvent and metallic dryers. The use of metallic dryers makes boiled linseed oil inedible. There are some products available that contain only heat-treated linseed oil, without exposure to oxygen. Heat treated linseed oil is thicker and dries very slowly. These are usually labeled as "polymerized" or "stand" oils, though some may still be labeled as boiled.
Ready to use. For ease of application dilute the first few coats with Pure Turpentine (up to 30%). Rub well into the wood using a lint free cotton cloth. After about 20 minutes, wipe off the excess with a clean lint-free cloth. Failure to do so will prevent penetration of future coats and leave a sticky surface. Repeat the previous steps once or twice at 24 hour intervals. Apply a final coat of Boiled Linseed Oil, again wiping off any excess. Allow this final coat to harden for a few days before use. A light rubbing in between coats with Liberon Ultra Fine Steel Wool (0000) will improve results. If the surface becomes damaged, work in a new coat.
