MURDOCH’S HARD OIL
Hard Oil™ is the perfect product to use when you are looking for a light look with minimal grain definition. It is the recommended finish for use in a pickling process. Use as the first coat to allow the white pigment to lay up on the surface.. It is also ideal as a wiping topcoat for cabinets and furniture after two coats of the clear Murdoch’s Hard Sealer™ or with Sealer and Stain. If you are looking for the high gloss of a "French Polish" hand-rubbed look, just brush on Hard Oil and don’t wipe. This extremely versatile formulation is a combination of a pure high-quality uralkyd resin, our Botanical Polymerized Tung Oil, low toxic driers, and the cleanest solvents available today!
The resin provides a rich high sheen when used as a film finish; that is brushed on and allowed to cure or a lovely Low Lustre, hand-rubbed surface if applied and wiped off. It offers incredible durability and a fast drying time
(4-6 hours). The Botanical Polymerized Tung Oil permits lubrication of the resin, making application as a brush-on finish not only possible, but very easy. The Polymerized Tung Oil also enhances the sheen as well as allows you to wipe the coating. This resin and our Polymerized Tung Oil formulation eliminates the "plastic" look that is seen in so many other resin based systems which offers protection while still maintaining a hand-rubbed appearance.
Polymerization, or cooking Tung Oil, is a process which utilizes controlled heating and cooling of the oil to change the oil’s molecular structure and facilitate cross-bonding of one application of Polymerized Tung Oil after another. Murdoch’s Hard Oil ™ employs the Loc-Lamin ® Wood Finishing System, which together with the polymerization process, increases the durability and integrity of our wood finish. Properly applied, you will never see any Sutherland Welles Ltd. ® product de-laminate or peel.
Hard Oil is the best choice when you need the protection that a urethane coating offers but you want a "softer" surface, one that doesn’t look like it has a lot of finish on it. "Protection without presence". The Hard Oil is the best choice when you want to control the color and keep a surface light, such as in the "Swedish look". The Hard Oil is your sealer coat and reduces the wood’s ability to take on color as well as minimizing grain definition.
In addition, it has a pleasant, citrus odor that dissipates rapidly. Its light-honey color will not change the natural color of the wood or alter any pre-applied stain color. It also minimizes the ambering that occurs with the aging process of a wood finish.
DIRECTIONS FOR USING MURDOCH’S HARD OIL™ ON TRIM, WALLS, CABINETS, FURNITURE
WOOD PREPARATION:
All wood surfaces should be free of lint, dirt, grease, wax, oil and old paint. If you are refinishing old wood, please make sure to remove any loose old finish and then lightly sand the wood using up to a 220/320 grit paper. New wood should be sanded with a 220 grit. Avoid using higher grits as they close down the wood pores interfering with maximum penetration of the Murdoch’s Hard Oil™ deep into the wood fibers.
APPLICATION OF MURDOCH’S HARD OIL™:
The typical process is to apply the Hard Oil as a topcoat over two coats of cured Hard Sealer. It can be applied with a good quality natural bristle brush and either left on the surface for a glossy finish, or wiped for a more satin or low lustre sheen. If you plan to stain the wood, we recommend a clear first coat of Hard Sealer or Polymerized Tung Oil Sealer depending on the amount of control you need over the stain. Mix our stain with the Sealer of choice, and use the Hard Oil as your topcoat. The Hard Oil topcoat can be brushed out and allowed to cure on the surface which will give more protection and a higher gloss. It is important to apply the Hard Oil thinly. Applying the product thickly interferes with the drying and curing time, in addition to wasting the product! Or you can apply the Hard Oil with a brush or rag and then wipe the surface using a dry rag or cheesecloth balled to fit in the palm of your hand. Use circular motions to develop the sheen with the final wipe being in the direction of the grain.
The surface should be dry and cured in four to six hours. Cure Test: lightly sand several inconspicuous areas. A fine, white powder indicates that you can safely apply another coat. If you allowed the first coat to cure without wiping, lightly sand using a 600 grit paper, vacuum and tack the surface prior to re-coating. If you applied the Hard Oil and wiped the surface you will only need to sand if the surface is too glossy or feels rough. It isn’t necessary for adhesion. The second coat is applied the same way as the first, as are all subsequent coats. If you wish to obtain a higher gloss, repeat the application process until the desired sheen is reached. The brush can be cleaned with turpentine, mineral spirits, or a citrus-derived solvent, such as Sutherland Welles Ltd. ®’s Di-Citrusol ™ or Citrus Thinner.
MAINTENANCE OF MURDOCH’S HARD OIL™ FINISH:
The Loc-Lamin ® Finishing System facilitates easy maintenance of a Hard Oil finish. Subsequent applications of Murdoch’s Hard Oil™ bond permanently with previously applied coats. Remove dirt and grime with a solvent of your choice. Lightly sand the surfaces to be re-coated with a 400 grit paper. Vacuum the surface. Thinly apply one or two coats of the Hard Oil according to the above stated instructions.
APPLICATION OF MURDOCH’S HARD OIL™ ON NEW WOOD FLOORS OR A RESURFACED WOOD FLOORS
We recommend three coats of Hard Oil to create a protected surface with the look of a hand-rubbed finish. This system is best for reclaimed wood surfaces with natural color left in the wood. If you want to stain the wood, we recommend using a different process.
Thinly apply the first coat of the Hard Oil using a good natural bristle brush or a short napped lamb’s wool applicator. Most of the first coat should be absorbed by the wood. Allow the coat to cure approximately 4-6 hours. After the surface is cured, either screen the surface using a 120/150 used screen, a maroon BCP pad or buff with # 1 steel wool or hand sand with 220 grit paper. Vacuum the floor thoroughly.
The second and third coats are wet buffed into the wood. Work in 3-4ft sections, apply the Hard Oil with a natural bristle brush and using # 1 steel wool, buff the entire surface of the floor in the direction of the grain. In areas where the buffing machine won’t reach such as in corners or on stairs, hand sand and wipe the Hard Oil completely off. In lieu of a third coat of Hard Oil, you may buff the floor using a high quality carnauba paste wax. The brush and lambs wool can be cleaned with turpentine, mineral spirits, or a citrus-derived solvent, such as Sutherland Welles Ltd. ®’s Di-Citrusol ® or Citrus Thinner.
RE- SURFACING MURDOCH’S HARD OIL™ FINISH OR APPLYING HARD OIL OVER AN EXISTING FLOOR FINISH:
The Loc-Lamin .® Finishing System facilitates easy maintenance of a Hard Oil finish. Subsequent applications of Murdoch’s Hard Oil™ bond permanently with previously applied coats. Remove dirt and grime with vinegard and water. Lightly sand the surface with 400 grit paper. Vacuum the surface. Apply a thin coat of the Hard Oil according to the above stated instructions for the second and third coats..
COVERAGE: 100-150 sq.ft./quart, 400-600sq.ft./gallon used as a stand alone finish. 250 sq.ft/quart, 1000sq.ft/gallon as a topcoat after two coats of Hard Sealer, Polymerized Tung Oil Sealer or Stain.
