Yes, boiled linseed oil can be sprayed after thinning with mineral spirits or paint thinner. It would save a lot of time, for instance, if you were using it on wooden fencing or an outdoor concrete or stone patio.
Mix one part linseed stand oil with two parts turpentine (or odorless mineral spirits). Cover the mixture tightly, and let it sit. Linseed stand oil is so thick that the two liquids won't want to combine right away—so be prepared to wait a few days for it to completely mix.
For protecting concrete or stone from freeze/thaw cycles and from salt and chemical damage, mix equal parts of Boiled Linseed Oil with Paint Thinner, Mineral Spirits or Varsol*. Concrete should be clean, dry and free of oils or wax film. Apply one thin coat uniformly over the surface with a stiff broom or brush.
The standard mixture is 1/3 Boiled Linseed Oil or Tung Oil, 1/3 thinner (mineral spirits, paint thinner, turpentine, naptha), and 1/3 varnish (poly, spar, etc..).
There are three surefire ways to waterproof your wood for years to come. Use linseed or Tung oil to create a beautiful and protective hand-rubbed finish. Seal the wood with coating of polyurethane, varnish, or lacquer. Finish and waterproof wood simultaneously with a stain-sealant combo.
Typically, three coats at 12 to 24 hour intervals are sufficient. When the last coat is completely dry, a light hand polishing can be done: This will enhance the satin finish and smooth the texture. Once it's done, plan for maintenance once a year or as needed (twice a year on floors).
To make an oil/varnish blend, mix equal parts of oil-base varnish, tung or boiled linseed oil, and mineral spirits, as shown. You can alter the mixture to suit your need. More oil increases penetration and color, and slows drying. Additional mineral spirits speed drying and decrease the thickness of the film.
No you don't need to thin BLO, or any other drying oil, to apply it.
Yes, mineral spirits can remove tung oil or linseed oil.
Mix Raw Linseed Oil with Paint Thinner (1:1 volume ratio). Wipe on the mixture and then wipe off immediately with a clean rag.
Mineral oil is non-drying, and will not form a solid barrier. Linseed oil is a drying oil. Although the drying time i Mineral Oil s long, it eventually forms a film on top of metal or a penetrative barrier beneath the surface of wood.
It doesn't matter, though. The most important thing here is that you apply a good amount of the mixture to the surface. Linseed oil penetrates the wood quickly. But to get the best results, you can dry it for 48 hours.
Raw Linseed Oil is also useful for softening putty and as a lubricant when French Polishing. Consider mixing the Linseed Oil with a small amount of White Spirit for the first coat only on bare timber, this will prime the surface.
The answer is, yes, you can use linseed oil as a medium with water mixable oils.
Boiled Linseed Oil & Wood
It beautifies any wood and, once cured, protects the wood from sun and water damage. It can really reinvigorate old dried out wood and bring it back to a healthy status. The powerful thing about an oil finish like BLO is its deep penetrating abilities.
Raw linseed oil makes a great finish for wood products if applied in thin coats and given plenty of time to cure, but it can take 2-10 weeks to fully dry depending on the environment and the thickness of the application.
Thinning oil paint with solvents such as mineral spirits achieves lower viscosity with moderate drying time and a matte appearance. Thinning with natural oils such as linseed oil achieves higher viscosity, slow drying time, and glossier results. There are many other options besides the ones listed above.
Raw linseed oil is a drying oil, and despite its short drying time, it will take between 30 to 45 days to cure and can be used as a topcoat.
No matter what you use for the sealer coat, sand it after it dries using a grit sandpaper that creates smoothness efficiently without causing larger-than-necessary scratches – most often a grit between #220 and #400 (P220 and P800). It's always best to sand lightly between every coat of finish to remove dust nibs.
Linseed Oils are a traditional option for nourishing and protecting wood, but which is the best one to use? Once dry both oils will provide a similar level of nourishment and protection to the wood and they will both slightly darken and enhance the woods natural grain.
It may take between 24-72 hours for BLO to fully cure, or dry out to the touch.
Like other finishes, linseed oil brings out wood's hidden color and exaggerates discoloration, only more so. But unlike a glossy finish that highlights faults, this oil leaves the wood with a dry, dull texture that tends to subdue an uneven or patchy-looking surface.
Yes, you can put polyurethane over linseed oil. But, you need to ensure the linseed oil is completely dry before polyurethane application. Both water-based and oil-based polyurethane can be used over linseed oil. But, you can only apply polyurethane over boiled linseed oil.
