Apply this DAP 16 oz. Natural Plastic Wood Solvent Wood Filler to your interior and exterior wood surfaces for the look and properties of real wood. Naphtha is a stronger solvent than mineral spirits, but this is rarely significant in wood finishing. This makes the filler paste the consistency of thick latex paint and a little easier to work with a paint brush. Wood stains are compatible with natural finishes such as varnish or shellac, and synthetic finishes such as polyurethane or acrylic. Soluble dyes dissolve in compatible solvents and provide greater grain clarity, meaning the grain shows through the stain.
Today, oil stain is manufactured in the greatest quantity and the most familiar to the amateur woodworker. Not being a VOC or HAP means there are no regulatory restrictions on how much of this solvent we, or the manufacturers we buy from, use. Today, the use of these formulations is under pressure from legislation continually pressing towards the reduction of solvent emissions.
When this happens, simply add some of this solvent, and the filler will be restored to the initial, applicable consistency. The petroleum distillates we use in wood finishing evaporate much slower than gasoline and are relatively safe to use in small quantities, even with poor ventilation. With the flexible plastic squeegee or artist’s palette knife spread a small amount of wet filler paste over the wood surface.
If for some reason the solvent is contaminated and may not be reused in the product, then the mineral spirits are considered hazardous waste and must be disposed according to federal regulations that pertain to such wastes. Includes: 2 oz. DuraStain Solvent Based Wood Stain, 6 oz. aerosol DuraSeal Wood Sanding Sealer, 6 oz. aerosol DuraLaq Wood Top Coat, 1′ Natural Bristle Brush, 2 oz. TruLube, Tack cloth, Assortment Pack of 6 sheets of sandpaper and a 2 pack of cloth wipes. Alcohol is the solvent because it dissolves solid shellac flakes and the dried finish, and it’s the thinner because it thins the liquid shellac after the flakes have been dissolved.
Because white and yellow glues are the same chemistry as latex paint, you can also use toluene or xylene to soften and scrub these glues from wood when you have glue seepage or finger prints you didn’t fully remove during sanding. The old unknown type of glue is white-ish and brittle and I have tried many solvents to remove it from the joints, but none has worked. Finish, thinner, and solvent compatibility is crucial: If you apply or clean a finish containing a solvent that softens and blisters the underlying stain or finish, it may partially strip or remove that finish. This sanding will remove most, or all, of the thin sealer coat is well, exposing raw wood again.
The timber preservation industry has invested considerable effort in developing, testing and marketing products for use where CCA wood preservatives are no longer permitted. Both types of pore filler are used extensively in guitar finishing currently, and each can produce a smooth, pore-free surface on porous hardwoods. This is a very thin solution and will leave only a thin lacquer film over the wood.
So there would be no way, or at least no inexpensive way, for lacquers and dye stains to comply if it weren’t for acetone. The wet, creamy, water-based filler paste is simply squeegeed across the wood surface – and into the pores – with a flexible plastic card or palette knife. Furniture, floors, doors, architraves and other wooden surfaces should be vacuumed or wiped down after sanding to remove surface contaminates prior to applying a solvent wood stain. Citrus solvent would be safe for almost all finishes except for some delicate water base films.
Most unused solvents are easily reused and re-mixed into the stain manufacturing process so that the solvent is generally not a hazard. It is easier to sand through the lacquer coat down to the wood surface at the edges than in the middle of the back or top. So it makes an excellent cleaner and degreaser and this is how it is used in most other industries.
Lacquer thinner solvent is strong enough to dissolve subsequent coatings together, and it can easily dissolve a cured lacquer finish as well. Before the mid-twentieth century, turpentine was widely used as a thinner and clean-up solvent for oil paint and varnish and also as an oil, grease and wax remover. But they don’t always have the depth of tone or color that oil stain imparts on the first coat.
On the same basis if you apply a finish containing a thinner that has no effect on the underlying stain or finish, you may still not achieve a good bond between the old and new finishes. Yellow carpet glues can be removed by applying vegetable oil with a soft cloth, but this can stain floors without a protective finish. Seal the wood and filled pores (a third time) with two wet coats of thinned vinyl sealer. Where water-borne wood preservatives are used, the zone of wood penetrated by the preservative solution swells and usually has to be re-dried before the component is put into service.
