Boiled Linseed Oil

Jasco® Boiled Linseed Oil is both a thinner for oil-based paints and a coating that creates a beautiful hand-rubbed finish on fine wood and antiques.

As a coating, Jasco® Boiled Linseed Oil helps bring out the attractive tones and grain patterns of natural wood —penetrating, sealing and protecting unfinished wood surfaces against damage from watermarks, scratches and warping.

As a thinner, Jasco® Boiled Linseed Oil improves the flow, leveling and durability of oil-based paints and adds a nice gloss to the final finish.

Produced from the seed of the flax plant, Jasco® Boiled Linseed Oil is processed to dry faster than raw linseed oil.


Paint Additive: A small amount of Boiled Linseed Oil may be added to oil-based paint to improve flow, lessen brush drag, and increase both the gloss and durability of the dried paint. Follow the coating manufacturer’s instructions for the addition of Boiled Linseed Oil. Do not use more than the recommended amount.

Furniture: Boiled Linseed Oil can be used to develop the full warmth and richness of unfinished wood and increase its resistance to water-marks, scratches and warping. Rub Boiled Linseed Oil into the surface and allow 5 to 10 minutes to penetrate the wood. Remove excess oil with a clean, dry lint free rag.

Gunstocks: Rub Boiled Linseed Oil into unfinished gunstocks to bring out their natural beauty and protect the wood. Remove any excess oil with a clean, dry cloth.

Other Uses: Apply Boiled Linseed Oil to condition farm and garden implements and to help protect metal surfaces from rust.

IMPORTANT: Carefully read all directions, notes and cautions prior to use. Only use this product as directed on the label. Protect eyes with chemical splash goggles and avoid prolonged skin contact.

HELPFUL TIPS: Boiled Linseed Oil must penetrate the surface of the wood in order to completely dry. Any excess oil remaining on the surface after application should be removed by wiping with a clean, dry lint free rag. An excessive buildup of Boiled Linseed Oil will cause a gummy residue or blotchy finish to form on the surface of the wood.

CLEAN-UP: Clean tools and equipment with Mineral Spirits or Turpentine.
