Can I use polyurethane without staining?
No. The purpose of stain is to alter the color of the wood. If you don't want to change the color of the wood you should not use stain. Polyurethane by itself is a perfectly acceptable finish.
Yes. If you prefer the look of bare wood, you do not need to use stain before applying polyurethane.
Yes! A polyurethane wood finish looks beautiful and is one of the most durable top coats for wood finishes. It works great on stained wood, raw wood, weathered wood finishes, and painted wood finishes too.
2. Staining is actually an optional step. Stains add rich color to the wood while allowing the natural beauty of the wood to show through. If you are already satisfied with the color of your wood, you can skip ahead to Step 3, Protect.
Wax, oil and varnish are three materials that will protect your furniture and that you can easily apply at home yourself. The three options will maintain the most "natural" aspect of the furniture, preserving the grain of the wood without adding big touches of colour, as paints, lacquers, etc.
The purpose of stain is to alter the color of the wood. If you don't want to change the color of the wood you should not use stain. Polyurethane by itself is a perfectly acceptable finish.
Water born polyurethane has the least colour change on wood. For a very natural look, apply thin coats then flatten the finish with steal wool this in my opinion give it the closest to an unfinished look.
Polyurethane doesn't do that so it needs a mechanical method to stick to the previous coat. If you don't sand, the varnish will flake over time particularly if it is a high wear surface. It will also make the surface much smoother.
How to Apply Polyurethane: When working with any finish. Use natural bristle for oil-based finishes and synthetic filament (polyester, nylon, or a blend of the two) for water-based and water-based oil-modified finishes. Don't use rollers or foam brushes—they create bubbles.
Polyurethane is so durable and water-resistant, it has largely replaced shellac and varnish as a wood finish. Originally, it had to be brushed on, but different formulations mean it can now be applied as a spray or by wiping it on with a rag.
When should you not stain wood?
You want to apply the stain when the wood surface and air are in the temperature range of 50° – 90°F. You also want to avoid the direct application of sunlight. Lastly, do not apply a stain if there is a forecast of rain in the following one to two days, or all your hard work could end up being washed away.
There are a few ways to darken wood without staining it. One way is to use a sealant or wax that will provide a darker finish. Another option is to paint or lacquer the wood in order to achieve a darker color.
Wet the Wood
Wipe down the wood to raise the grain. If you don't raise the grain at this point in the process, the stain will raise it later. However, re-sanding to get the wood smooth again removes much of the stain. Let the wood dry, then sand with 180 to 220-grit paper.
Natural finishes can be made from oils such as Tung oil, mink oil, linseed oil or mineral oil. It is even possible to stain the sanded wood with a mild or matching stain, but it should be water based. By repeating the process of sanding and oiling, a beautiful natural finish will enhance and protect the wood's surface.

It's no secret that many paints, varnishes, and clear coats emit VOCs and other harmful compounds after they've been applied to a surface. But of all types of fumes and toxins, avoiding polyurethane fumes may be the most essential due to their potential for harmful side effects.
Polycrylic is not as durable as polyurethane and is meant to be used only on interior surfaces such as cabinets, furniture, and trim. It shouldn't be used in exterior applications or on surfaces that are subject to lots of wear, such as floors, or that are exposed to water.
It requires around 2 to 4 hours for a water-based polyurethane and 6 to 10 hours for an oil-based to cure and eventually be subject to a second coating. Figures as these still vary depending on the type of base, humidity ratio, air pressure, and even the state of the woodwork.
You Don't Have to Choose
Or, you can stain first and seal second. Some woods can go without staining and sealing. Cedar, for example, can be left as it is. It naturally repels water and it will also change color, in time, to a classic grey that many homeowners love.
Wood can be left unfinished if it won't encounter weather, water or significant handling. If your project is placed outside, will be somewhere wet, or will be used on a regular basis, then you should apply wood finish.
Can you wait too long between coats of polyurethane?
It's all about adhesion. When you recoat after 2 hours you get a chemical bond between layers. If you let it go longer than that, you need to wait 24 hours so it's hard enough to sand and get a mechanical bond.
A wet sander can be used after sealant, varnish, or polyurethane has been applied to smooth out bumps, scratches, or imperfections on the surface. In addition to making scratches less visible, the water gives better control over the thickness of the finish.
Allow each coat to dry fully. To give the subsequent poly layers something to bond to, sand lightly between coats with 320-grit sandpaper wrapped around a hard block.
Vacuum or Wipe Away Dust
If dust or other particles settle on wet polyurethane, they can create a rough surface. This defeats the goal of a smooth topcoat. After sanding, dust and vacuum the surface and room as thoroughly as possible. Wipe the surface with a damp, lint-free cloth or sponge.
- Poor thermal capability.
- Poor weatherability.
- Attacked by most solvents.
- Utilize toxic isocyanates.
- Flammable.
Shellac – Shellac is a varnish made from the resin of the lac bug. It is a softer finish that is often recommended for lighter-colored woods. It is also better for areas with high moisture and frequent wear, as it dries much faster than polyurethane.
*How Do I Remove Brush Strokes from the 3rd Coat of High Performance Polyurethane? Sand down the final finish with a 220-grit foam sanding pad, and then add another layer of General Finishes High Performance PolyurethaneTopcoat. Apply liberally than you did previously without heavy back-brushing.
You can sand and spot-apply polyurethane, though you risk an obvious patch. The alternative is to screen and recoat the entire floor. To get rid of heel marks and scuffs on a waxed floor, polish the mark with 000 (extra fine) steel wool and hardwood-floor cleaner. Wipe the floor dry and rewax.
Some finishes rub out better than others. Those that respond best are hard, film-forming finishes like lacquer, shellac, varnishes, and polyurethanes.
Without waiting for the wood to dry, stain and sealant would not penetrate the wood properly, diminishing its ability to protect the wood from weather damage.
What time of day is best to stain wood?
Applying a deck stain in direct sun will cause the stain to dry to quickly and can result in premature stain failure. In the summer, stain your deck in the morning or evening so the deck surface isn't too hot. Remember, the surface temperature of the deck can be much hotter than the air temperature.
Deft® Clear Wood Finish is a semigloss, brushable lacquer that will give a crystal-clear finish and won't darken or yellow with age. It will seal and finish. It won't skin over or harden in the can, but will dry in 30 minutes with recoat in 2 hours. We have found a special use for Deft in finishing woodturning.
Staining wood with coffee grounds can be a simple and effective way to give your wooden surfaces a unique and natural look. We found it to give a strong and effective finish. It's also nice, as you are recycling the coffee grounds in the process. This will only work on a flat piece of wood.
Minwax® PolyShades® is an easy way to change the color of your currently stained or polyurethane finished wood. There's no stripping or heavy sanding necessary to remove the old finish!
If your existing deck stain is: Light: Apply a similar or darker stain color without additional preparation required. Dark: This will be hard to 'cover' with a lighter semi-transparent color, as the old/dark color will come through. If you want to lighten up the color of a dark deck, consider a lighter solid stain.
Without diligent and effective preparation, your refinished product is up against obstacles like dust, wax, existing stain or irregularities in the wood surface. Fight as you will – if you don't spend a bit of time making sure the wood surface is clean, your end result isn't going to live up to expectations.
Gel-Based Stains
When it comes to application, gel stain requires less preparation than regular stains and paints. They are thicker and messier to apply. Use a rag or cloth to apply for best results. Gel stains are the best wood stain for furniture or floors made of pine or other woods prone to blotching.
Varnish stains are more difficult to use than oil stains because there's less time to wipe off excess. Brushing and leaving the excess usually leaves prominent brush marks that stand out because they're colored.
I again took the cheap DIY route with a homemade beeswax + olive oil sealer. And it dramatically changed the color of the wood. I don't know how much difference the stain in the final color. Melt the two ingredients together in a double boiler (or glass bowl over a pot of simmering water) until combined.
Shellac: The natural choice. This traditional finish comes from natural resins secreted by the lac bug. These secretions are collected and processed into flakes that dissolve in ethyl or denatured alcohol. You can also buy shellac premixed, it's slightly cheaper than polyurethane.
What is the least shiny wood finish?
A matte or satin finish offers the lowest level of shine and reflects the least amount of light. This type of finish is perfect for homes with high traffic areas or homes with kids or pets as small scratches won't be as noticeable.
Can I use olive oil on wood furniture? Yes, you can. Use a cloth to work the oil into the wood grain, rubbing back and forth. When the wood has absorbed the oil, leave it for ten minutes then wipe the excess off with a clean cloth.
Polyurethane is a protective top coat for indoor stained wood, such as furniture. Its clear, hard finish prevents damage from scratches, scuffs and spills. Different types of polyurethane are available based on desired appearance and protection needs.
The best option is to use a varnish or lacquer to give the wood a high gloss finish. While varnish can be sprayed or brushed on, lacquer is best applied by simple spraying. Spraying makes the surface seem finer than painting as it doesn't leave any strokes behind.
Polyurethane is so durable and water-resistant, it has largely replaced shellac and varnish as a wood finish. Originally, it had to be brushed on, but different formulations mean it can now be applied as a spray or by wiping it on with a rag.
- Prepare the wood. Using a clean, damp rag, rub the surface of the wood. ...
- Open the water-based polyurethane can and gently mix it with a paint stirrer. ...
- Paint it on. ...
- Sand lightly.
You can use a brush, rag or spray for your project. The best way to apply polyurethane will depend on the surface of the wood project. Brushes are best for flat surfaces such as tables or some chairs. Brushing a rounded, contoured or vertical surface is more likely to create drips.
You should use an automotive polishing compound and a buffer for big areas. Small areas will have to be polished by hand unless you have some funky buffing tools. Make sure the poly has cured for a minimum of 4-5 days at 70f.
Polyurethane Wood Finish
Water-based polyurethane dries quickly and can be used on bare, stained or painted wood. It provides a clear, natural sheen that does not yellow with age.
Does Polyurethane Protect Against Water? This finish protects your floors, but polyurethane is not waterproof. It will make your floors water-resistant, though — the coating repels water and helps prevent water absorption.
What is the best applicator for polyurethane on wood?
Lambswool applicators
A lambswool applicator on a wood block is the recommended method for applying oil-based polyurethane to a hardwood floor. But if you've recently bought a lambswool applicator, be careful.
- Thin your oil-based polyurethane with two parts polyurethane and one part mineral spirits. ...
- Brush the sealer on with a natural-bristle brush using long, even strokes. ...
- Load your brush by dipping it about 1 in. ...
- Keep a wet edge by overlapping each pass until the surface is completely coated.
To give the subsequent poly layers something to bond to, sand lightly between coats with 320-grit sandpaper wrapped around a hard block. Note: The first coat needs the most sanding to appear smooth; don't worry if it doesn't look as flawless as you'd like at first.
Thus, it's best to wait until all coats have been applied and dried before walking through the room. After that final coat, your floors should be off-limits for 24 hours. This is the only way to avoid any damage. Also, if you can swing it, hold off 3-7 days before moving furniture back into the room.
