The best way to completely avoid wood grain from raising is to use oil-based finishes instead of water-based ones. Oil, when absorbed by the wood does not raise grain, instead, it strengthens it. It replenishes the natural oils in the wood that have dried off with time.
Grain raising refers to a coating failure that especially occurs in the coating of wood. When a water-based coating is used on the coating of wood surfaces, fibers stick up from the wood, causing a dull appearance and rough surfaces of the paint finish. This is known as grain raising.
I will typically raise the grain on softwoods twice, flooding the surface the 1st time, sanding, then wetting more lightly the 2nd time. Softwoods soak up enough water to raise large areas of grain, and the swelled fibers in those areas are removed by sanding flat.
When using OIL BASED finishes: The best method for bringing out the natural characteristics of wood grain is to use a penetrating oil like Tung oil, Walnut oil or double boiled Linseed oil.
Pure Tung oil gives off a deep, rich, matte-like finish. It really accentuates the grain patterns and adds depth to your wood’s surface. Polymerized produces a more shiny, reflective surface.
Acetone is commonly found in fingernail polish remover. … Repair techniques for acetone damaged wood are typically for the finish only, but If acetone is spilled on bare wood, it will not cause any damage due to the rapid evaporation rate, but it may raise the grain slightly.
3 Don’t skip the sanding! It smoothes out the dried Minwax® Stainable Wood Filler, removes minor nicks and scratches, and opens the pores of the wood to accept more stain.
If you are removing raised grain from wetted wood, be sure to use fresh fine-grit sandpaper, and make the wood feel smooth—don’t go any deeper. 320 to 400 grit sandpaper should work well.
Oil-based polyurethane varnish brings out wood’s natural beauty and grain. Our 8-step approach shows you how to apply the varnish successfully. A good-quality natural-bristle brush, a reasonably dust-free, well-ventilated space and some patience are all you need.
Mineral spirts won’t raise the grain. It also has the benefit of highlighting any areas of torn grain or scratches before the finish is applied.
Originating from China and South America, tung oil—an extract from tung-tree nuts—is a natural drying oil that coats your fine wood furnishings with a transparent, wet finish. It enhances the color of your wood, offers excellent protection and is eco-friendly.
It is important to apply this finishing oil only on bare or previously oiled wood, since any other finish such as paint, varnish or wax will prevent the penetration of the oil. Painted, varnished or waxed wood will therefore need to be cleaned and/or stripped to bare wood before proceeding with linseed oil application.
Tung oil hardens upon exposure to air (through polymerization), and the resulting coating is transparent and has a deep, almost wet look. Used mostly for finishing and protecting wood, after numerous coats, the finish can even look plastic-like. Related drying oils include linseed, safflower, poppy, and soybean oils.
No matter what type of edge you’re going for, always maintain steady pressure and sand with, not against, the grain. Don’t employ sandpaper to remove things like pencil marks or dried glue, but do use it to smooth joints or filled nail holes.
Brushing plastically works the texture of the wood. The bristles remove more of the soft early wood, while the harder late wood tends to remain. One might say that wood is artificially aged as the natural weathering effect is significantly accelerated by mechanical brushing.
Our Experts Weigh In. Woodworking Expert – Michael Dresdner: “Yes, I would put a coat or two of oil-based polyurethane on for more durability, and it is fully compatible over the dried tung oil (or linseed oil, or any other drying oil for that matter.) … Add at least three coats, at one coat per day.
Reapplying Tung Oil every 6 months would be like reapplying lacquer every 6 months. Tung doesn’t evaporate, and in my experience, it doesn’t even wear down quickly. By reapplying it you are only trapping finger goo and grunge under the finish.
- Use a clean, dry, soft rag to rub, a natural bristle, or foam brush to stroke on a generous first coat of tung oil.
- Wait up to 40 minutes to continue after the porous surface has absorbed the first coat.
- Repeat steps 1 and 2 by applying a second coat and allowing it to absorb into the surface.
The first is to raise the grain and sand it smooth before applying the water-based product. This is called raising the grain, sponging, whiskering or de-whiskering. Once sanded smooth, the grain won’t raise again nearly as much as it did with the first wetting.
Rub entire cutting board with several coats of a food-safe finish like mineral oil, walnut oil or beeswax, allowing oil to fully absorb into the wood. Allow cutting board to dry overnight before use. Tip: Most food-safe finishes need to be reapplied regularly.
To restore a cutting board, a 150-180 grit sanding will be necessary to remove as much knife marks as possible. If the surface is too damaged or that the marks are too deep, you can use a more aggressive paper (100-120 grit) with a sanding machine. Remove dust the surface and make sure the board is clean.
We recommend using a Tung oil for oak surfaces. This type of oil will maintain the oak’s colour as well as character. However, if you would like to darken the oak, hard wax oil is more ideal. Another popular oil for oak is Danish oil.

To make your boards absorb evenly, use a wood conditioner after you’ve sanded the boards. Softwoods like cedar, pine or ash don’t always absorb and can turn out blotchy. A wood conditioner will stabilize the wood and allow it to absorb the stain for a consistent golden glow.
Pour the 4 cups of hot water that you brought to a boil into a bucket. Add ¾ cup of baking soda, ½ cup of ammonia and 1 tbsp. of white vinegar. Stir the contents with a wooden spoon.
The denatured alcohol will dry quickly and clean the wood. After the wood is dry, stain, paint or install the untreated wood. Not often used because it’s been replaced with polyurethane and other resins, shellac works best if thinned with denatured alcohol.

Sanding with a steel-wool substitute between coats of stain is useful for two reasons. … In addition, it adds some “tooth” to the surface that helps the next coat of stain adhere and absorb better and more uniformly. Wipe the surface with tack cloth to remove dust before you begin the next coat of stain.
If applied too thickly, they won’t dry properly and will remain tacky to the touch. This can also happen if the wood wasn’t stripped and sanded completely down to bare wood, since the stain will sit on the surface rather than soaking into the wood.
1 Answer. Sanding with or against the grain doesn’t matter much until the last sanding stage, if that. Lots of us use random-orbit sanders which sand in all directions at once, and that works Just Fine.
In a technical sense, sanders using a rotating pad — like rotary tools and orbital sanders — sand neither with nor against the grain, but they still leave behind very minor scratches, or “squigglies.” If you have no intention of finishing the wood object in question, these scratches are irrelevant; but if you do, a …
For some types of poly, nothing happens if you don’t sand between coats of polyurethane. However, most polyurethane will not adhere properly if you skip sanding dust nibs and brush marks on the finish. The polyurethane finish will eventually peel off or become deformed.
Polyurethane Finish Step#1: Start With a Thick Coating Sand lightly with 240-grit sandpaper between coats, then let the last coat dry for at least 24 hours. This is standard practice with any wood finishing job, and is nothing out of the ordinary.
Is One Coat of Polyurethane Enough? No, one coat of Polyurethane is not enough to provide a nice finish. . Apply three to four coats of polyurethane for a professional quality finish. A single coat won’t protect the wood from scratching and denting.
