Hemp seed oil is derived from the versatile hemp plant. Popular Mechanics published an article on the hemp plant back in the 1930s stating that it had potentially 50,000 uses. Second-pressed hemp seed oil also offers an enormous number of uses, from home building, industrial uses, to cosmetics. Cleans easily w/ Dr. Bronner’s Soap.
Second-pressed hemp oil can be used in the construction of alternative homes, whether of cob, rammed earth, adobe, hybrid adobe, paper crêpe, or straw bale, and has many applications in the more traditional-type wood house. Used straight, hemp oil can be used as a varnish to help protect surfaces. Hemp oil mixed in grout creates a water-resistant mixture that is adherent. Hemp oil in window putty makes it waterproof and more plastic. It has been tried as a resin and oil finish for boats and wooden decks.
Second-pressed hemp oil mixed with vinegar, salt, borax, and citrus oil, for example, can be used as a cleaner and a preserver of wood around the house and for outdoor furniture. Because of its antimicrobial and antifungal properties, hemp oil helps prevent mold. A slight coat of hemp oil with orange or lemon oil is good for any woodwork, for example, to shine up cabinets. Be sure to buff dry for maximum penetration. Do a small testing before doing the main project.
In manufacturing, hemp seed oil can be used as a lubricant for bicycle chains, chainsaws, and other machinery. It can be used as an ingredient in solvents, putty, printing inks, and biodiesel fuels, and in candle-making. Many bicycle shops have used hemp oil as a chain lubricant for a smoother and quieter ride, as well as for de-greasing bicycle frames and for lubricating all parts of a bicycle including rusted parts. There are so many other possible applications only waiting to be discovered by creative thought.
Another area where second-pressed hemp oil has many uses is in the broad category of cosmetics. It can be used for making soaps, shampoos, conditioners, lip balms, shower gels, baby creams, massage oils, moisturizers, body lotions, bath oils, and salves. Depending on the formula, 2–20% hemp oil can be used. Keep in mind that there are no solvents used in the production of our hemp oil. Thus, for cost and effectiveness, it is an excellent quality value. Small trials are first performed to determine the desired result.
In its drying properties, hemp oil is somewhat like linseed oil. Polymerization of the oil is actually an asset because of its ability to dry out on surfaces faster. In fact, linseed oil and hemp oil, up until 1937, were used in the majority of all shellacs, paints, varnishes, and resins. Large companies all used hemp oil in their products until the prohibition against hemp brought it to halt.
With care, second-pressed hemp oil can be heated up for 10 minutes, which will polymerize it giving it a faster drying time and quality. Used straight or mixed with orange oil extract (in place of turpentine), it helps to enhance finishes.
Second-pressed, non-filtered hemp oil is available. Non-filtered allows the oil to retain the full beneficial properties of the hemp plant. We are currently offering this tech-grade hemp seed oil (almost first-pressed oil) at an affordable and attractive price.
Ten gallons of hemp seed oil has been donated by Herbal Products & Development to the Navaho (Dinah people) for a medicine lodge in Wheatfield, AZ, and to the Hopi for a cultural center in Piñon, AZ. Hemp oil is also being extensively tested for projects nationwide for use as finishes on walls, floors, and furniture.
Examples of second-pressed hemp seed oil used for house construction can be found in Teresa Berube’s book, How I Built My Organic Home of Mud and Hemp. In it, she lists recipes using hemp oil for paint, waterproofing, sealant, roof and floor oils, kitchen tile, and simple plastic glues. Recipes are the following:
For semi-gloss or gloss paint, add hemp oil to thicken the mixture of clay paint base.
For putty, add hemp oil to clay.
For a bathtub, burnish and waterproof with 4–7 coats of hemp oil.
For floors, use 4–7 coats hemp oil. It transforms cob into a one-piece linoleum.
For grout, add hemp oil and tea tree oil to make a glue of clay.
As a varnish, use 100% hemp oil, brushing it on, giving it 1–5 days to dry.
Hemp oil also helps waterproof cloth.
As a floor oil and sealant:
For a 1st coat use 1 gal hemp oil to 1 cup Citrisolve (orange oil). For the 2nd, 3rd, and 4th coats decrease hemp oil to 1 quart, 1 pint, 1 cup, to the same 1 cup of Citrisolve.
For drywall cold weather keeping, the first two coats can be hemp oil straight, the final coat add 1/4 cup beeswax. Apply when warm. For built-in furniture, the first two coats can be hemp oil straight, rubbed in. Try on masonry, pavers, field stones, brick. A few coats will help seal.
For a kitchen tile glue: 4 cups water, 3 cups kaolin clay, mix, and add 1 1/2 hemp oil, 1 tbsp. tea tree oil, 1 tbsp. psyllium husks (already mixed with 1 cup water). Set the tiles, let dry before grouting.
For hemp glue: 1-pint water, 1 1/2 cups hemp oil, 1 tbsp. psyllium husks. Mix and add 3 cups kaolin clay, 2 tbsp. hemp hurd flour.
A basic cleaning formula is a 1:1 ratio of hemp oil to lemon oil, orange oil, or vinegar. Patch test first. It cleans and refreshes woodwork. Lightly apply. Buff well and wipe clean with dry cloth after each application. Also clean up old garden tools or any oxidized metal. Rub first with steel wool, then apply a mix of hemp oil and orange oil, buff and dry with an old towel.
The company Rio Rockers has used hemp oil as a finish on wooden rockers and chairs. They begin with a 2:1 solution of turpentine to hemp oil for a first coat. The 2nd coat is a 1:1 ratio, 3rd coat is 1:2, and the 4th coat is 1:4. The finish is vigorously hand rubbed and burnished until it is well absorbed. Each coat could take 1 to 5 days drying time, depending on the weather. (Our preference for a solvent is orange oil).
Colorants with iron oxides could be added to hemp oil to produce natural pigments for use on external walls or on furniture. If the hemp oil has been heated, the drying time is faster. This could also be the final wash on landscaped, free-formed walls. Use approx. 2% in the plaster mix. Do a sealant coat for the final coating.
Philip Mirkin, author and pioneer in hybrid adobe construction, states that hemp oil can be substituted for linseed oil. See his book The Hybrid Adobe Handbook for recipes. Hemp oil at approximately 2% can be used in the finish coat on paper crêpe/hybrid adobe exterior walls. It can also be used for interior walls as a coating on clay surfaces with a final coat as a sealant. See also his website: www.hybridadobe.com
As a good late spring or summer project, if you want to spruce up and recondition your outdoor deck furniture and benches, you couldn’t do better than using hemp oil.
