Staining wood is one of the most rewarding DIY skills you can master.

What Is the Function of Wood Stain?

The primary function of wood stain is to add color to wood, enhancing its natural grain or darkening it for a richer finish. Stain is also invaluable in furniture restoration, especially when you've stripped an old piece down to bare wood and need to bring it back to its original hue. Stains are typically made from aniline dyes, available in powder or granule form at most paint stores, ready to be mixed with water, alcohol, or oil. You can also find pre-mixed stains at hardware stores that often include added protection against fungi and insects.

Types of Wood Stains
Water-Based Stains
Traditional water-based stains are the simplest to use, but they require multiple coats and can cause the wood grain to swell. They are not recommended for very porous woods. For those projects, consider a different approach. If you're working on a kitchen cart or island, our kitchen islands and carts collection might inspire your next upcycle.
Alcohol-Based Stains
Alcohol-based stains dry very quickly and are ideal for porous woods. Because alcohol evaporates fast, it doesn't penetrate deeply, resulting in a lighter but vibrant color. This is perfect for accent pieces like wall decor or small furniture items.
Oil-Based Stains
Oil-based stains penetrate deeply, providing an even, uniform color. They take longer to dry, but the results are durable and rich. Use these for high-traffic items like dining tables or desks.
How to Apply Wood Stain
Application can be done with a brush or a simple pad made from a lint-free linen cloth stuffed with cotton wool. Always test your stain on a hidden area first. To hide blotches caused by uneven staining or glue spots, use oil-based color palettes that can be mixed until you achieve the perfect shade. This step is crucial not only for adding color but also for returning a piece to its original color after complete stripping.
Two Main Methods for Staining Wood
- Method 1: Apply a stain (water or alcohol-based) with a sponge, pad, or brush, then finish with a clear protective coat. This gives you maximum control over the color depth.
- Method 2: Use a pre-mixed "stained" varnish that combines staining and sealing in one step. This is faster but offers less control. For your finished piece, consider complementing it with rugs or curtains from our decor collections.
Staining Outdoor Furniture
If you're staining outdoor furniture, choose a stain with UV protection and water repellent properties. Our outdoor patio furniture collection features pieces that are perfect for a fresh stain job. For garden structures, explore our sheds and greenhouses.
Staining Tips for Beginners
- Always sand wood thoroughly before staining.
- Apply stain in the direction of the grain.
- Wipe off excess stain immediately for a lighter color.
- Allow proper drying time between coats.
- Seal with a topcoat for durability.
Frequently Asked Questions
What is the difference between stain and varnish?
Stain adds color to wood, while varnish provides a protective clear coating. Some products combine both functions.
Can I stain over painted wood?
No, stain is designed to penetrate bare wood. You must strip or sand off paint first. For painted pieces, consider our beds or dressers for a fresh start.
How long does wood stain take to dry?
Water-based stains dry in 1-2 hours, alcohol-based in 30 minutes, and oil-based can take 6-12 hours or more.
Do I need to seal wood after staining?
Yes, a clear topcoat protects the color and wood from moisture and wear. For bathrooms, check our bathroom vanities for inspiration.
Can I use wood stain on MDF or plywood?
Yes, but MDF absorbs stain unevenly. Use a gel stain or a pre-stain conditioner for best results. For sturdy alternatives, browse our bookcases and shelving units.
