Interior Wood Stains

Interior stain is colored liquid that soaks into bare wood to change its tone and either show off or hide the grain. It’s for furniture, cabinets, doors, trim, molding, and floors — anything wood and indoors. The two decisions that matter most: oil-based or water-based, and semi-transparent (grain shows) or solid (grain hides). Get those two right for your wood species, and the rest is prep and patience.

Here’s the honest truth nobody tells first-time stainers. The same can of stain looks completely different on oak than it does on pine. Wood is a product of nature, so it can vary from tree to tree, even in the same wood species. That’s why every guide worth reading says the same thing: test on a hidden spot first.

Oil-Based vs. Water-Based: The First Fork

This is where you start. Both color the wood. They behave differently going on and cleaning up.

Oil-based gives you breathing room. Oil-based stains give you a longer working time, enabling you to stain floors, cabinets, paneling and doors without the worry of dried lap marks. They do not raise the grain, eliminating the need for additional sanding. That longer open time is the reason floor and cabinet finishers reach for it — fewer lap marks on big surfaces. The penetrating oil-based Wood Finish dries in 2 hours, makes it possible to stain in a day, and resists lapping for even color.

Water-based is the faster, cleaner path. Water-based stains are lower in odor than oil-based stains, dry faster — enabling you to stain and finish in one day — require only soap and water for clean-up, and come in a wider range of vibrant stain colors. The water-based solid color line runs one-coat color that dries in 1 hour, is 5x thicker for easier application, and is ideal for small projects, unfinished furniture, cabinets, doors and trim. That low-odor point matters in tight, well-insulated Montana homes where you’re not flushing fumes out fast.

One catch worth knowing before you buy: the water-based solid color stain is for interior use only. Not for use on floors. If you’re staining a floor, that’s an oil-based job.

Type	Dry Time	Working Time	Cleanup	Grain
Oil-based Wood Finish	~2 hours	Longer — good for floors, cabinets, doors	Solvent	Does not raise grain
Water-based solid color	~1 hour	Faster — stain and finish in a day	Soap and water	Hides grain (not for floors)

Semi-transparent or solid

Decide whether you want the wood to read as wood. Semi-transparent water-based stain showcases wood grain. Solid goes the other way — solid color shows more color, less grain, while maintaining the wood texture.

Color range is deep. The oil-based Wood Finish comes in 36 colors. The premium oil-based Color Series opens up 240+ oil-rich colors. On the water-based side, the solid color stain runs 200+ tintable color options with the ability to tint custom colors.

Match the Stain to Your Wood

This is the step that separates a finish you’re proud of from a blotchy mess. Different species drink stain differently.

The easy ones are open-pored hardwoods. Oak has a strong grain pattern and large, open pores that absorb stain readily. For that reason, oak is attractive with nearly any color of stain. Ash and chestnut behave the same way and should be stained in the same manner as oak.

The stubborn ones resist color. Hard maple is an extremely dense, tight-pored wood that does not absorb much stain. Unlike oak and ash, the grain pattern of maple is uneven, causing it to absorb stains in varying degrees. Cherry’s the same story — it has a subtle grain pattern and small pores which do not absorb as much stain, making it difficult to make significant changes to its natural color.

Now the ones that bite Montana builders. Pine, fir, and cedar are everywhere around here, and they blotch. These three popular softwoods look beautiful when finished naturally or with only a light application of stain. Problems arise, however, under darker stains, for all three absorb stain unevenly, especially around knots and blemishes. The fix: always apply a liberal coat of a pre-stain wood conditioner prior to staining and even then select light to medium colors. These softwoods are also less likely to exhibit blotchiness if stained and finished with PolyShades or Gel Stain. Same conditioner-plus-lighter-colors approach applies to alder and aspen, which absorb stains unevenly, and birch, which does not absorb stain evenly and should not be stained with dark colored stains.

Oily tropical hardwoods need oil-based, period. For mahogany, rosewood and ipe — noted for their dark, rich colors and high levels of natural oils — when staining is needed, always use an oil-based stain to ensure compatibility with the natural oils in these woods.

Prep and Application

The warranty doesn’t cover sloppy prep, so this part protects both your wallet and your weekend.

Start clean. Start with bare, stripped wood that’s clean and dry. Sand with #220-grit sandpaper in the direction of the wood grain and remove sanding dust. Apply Pre-Stain Wood Conditioner — especially on soft woods — for best, even color.

Then the staining itself. Test before staining on a hidden spot. Stir stain well before and occasionally during staining — don’t shake or thin it. Wipe away excess stain, working with the wood grain to blend lighter and darker areas. The longer you wait, the darker and richer the color. Want it darker? To darken color, recoat. Do not sand between coats. If happy with the color, let dry completely before applying a protective topcoat.

Stain colors the wood. It doesn’t protect it. Finish every project with a clear protective topcoat like Fast-Dry Polyurethane or Polycrylic Protective Finish.

One safety item that’s not optional with oil-based products. Rags, steel wool, and waste soaked with oil-based stain may spontaneously catch fire if improperly discarded. Immediately place them in a sealed, water-filled, metal container and dispose of in accordance with local fire regulations. A pile of oily rags in a warm shop is a real fire — treat it that way.

Specialty Formats Worth Knowing

A standard penetrating stain isn’t always the right tool. A few alternatives solve specific problems.

Gel stain handles vertical surfaces and odd materials. It’s a non-drip oil-based formula that is ideal for vertical surfaces and can be used on both wood and non-wood surfaces. Doors and cabinet faces you’re staining in place — that’s gel territory.

PolyShades does two jobs in one. It’s a stain and polyurethane finish combined, and as noted above, it helps tame blotchiness on pine, cedar, and fir.

For small fixes, the format scales down. There are stain markers for touch-ups, and stains come in half-pint sizes for small projects where a quart is overkill.

Western Building Center carries interior stains in oil-based and gel formats — including Old Masters wiping stains in colors like Golden Oak, Red Mahogany, Provincial, Maple, Early American, Cedar, Spanish Oak, Fruitwood, Weathered Wood, Natural Walnut, American Walnut, and Espresso, plus Old Masters gel stains and pure tung oil, and Penofin products.

Frequently Asked Questions

Oil-based or water-based — which should a beginner use? Water-based is the more forgiving path for most small interior projects. Water-based stains are lower in odor, dry faster — letting you stain and finish in one day — require only soap and water for clean-up, and come in a wider range of vibrant colors. The catch: the water-based solid color stain is for interior use only and not for use on floors. For floors, go oil-based, which gives a longer working time so you can stain without the worry of dried lap marks.

Why does my pine look blotchy after staining? Because pine drinks stain unevenly. Pine, fir and cedar absorb stain unevenly, especially around knots and blemishes, particularly under darker colors. The fix is to apply a liberal coat of pre-stain wood conditioner before staining and select light to medium colors. A stain-and-poly combo like PolyShades or a gel stain also helps even things out.

How do I make the color darker? Two ways. First, leave it on longer before wiping — the longer you wait, the darker and richer the color. Second, add a coat. To darken color, recoat. Do not sand between coats.

Do I need a topcoat over stain? Yes. Stain colors the wood but doesn’t protect it. Finish every project with a clear protective topcoat like Fast-Dry Polyurethane or Polycrylic Protective Finish.

How long does stain take to dry? Depends on the type. The oil-based Wood Finish dries in 2 hours, making it possible to stain in a day. Water-based solid color stain is quicker — one-coat color dries in 1 hour.

What’s the safest way to throw out oily rags? Never wad them in a trash can. Rags and waste soaked with oil-based stain may spontaneously catch fire if improperly discarded. Immediately place them in a sealed, water-filled, metal container.

Will the color in the can match what I get on my wood? Not necessarily. Color charts are for reference purposes only, reproduced using digital techniques — always test stain on a hidden area of the wood to verify the desired color. Wood species changes the result every time.
