Must-Have Supplies for Wood Finishes
Having these essential finishing products on-hand will allow you to tackle a variety of wood surface preparation and finishing tasks:
Stains come as oil-based or water-based. Oil-based provide deeper color but take longer to dry while water-based stains dry quickly with lighter color. Gel stains offer thicker application for more control over color effects. Always test stains first on scrap wood to ensure you achieve the intended effect.
Paints and enamels suitable for wood come in different sheens from matte to high-gloss. Latex and oil-based options work for both painted and stained finishes. Primers help paints adhere to wood. Some all-in-one primer+paint products simplify application.
Oils and waxes like tung, linseed and Danish oils penetrate wood pores without leaving a surface film. They offer some protection while preserving natural grain and texture. Waxes add luster while allowing the wood to breathe. Polyurethanes seal and protect wood under a clear, plastic-like film. Oil-based versions provide the most durable finish. Water-based options dry faster with less odor.
Varnishes contain resins that cure into a transparent, protective film. They enhance wood grain while providing a harder, more scratch-resistant finish than oils. Spar varnish holds up especially well for outdoor projects.
Brushes and rags. High-quality brushes suited to the finish type lead to smooth application. Lint-free cloths apply oils/waxes cleanly.
Abrasives prepare wood for finishing. Use progressively finer sandpaper like 100-220 grit to sand initial imperfections, then 400+ grit to achieve an ultra-smooth foundation that finish adheres to evenly. Steel wool (super-fine 0000 grade) smoothes between finish coats.
Solvents like paint thinner clean oil-based products from brushes. Denatured alcohol works for water-based products. Mineral spirits remove some stains/varnishes. All finishing solvents require safe handling.
Prepping the Wood Surface
Proper prep before applying any finish ensures maximum adhesion and aesthetics:
The first step is sanding the wood with the appropriate grit sandpaper to smooth any rough areas. Always sand with the grain to avoid scratch marks. Use a sanding block for flat surfaces. For intricate carvings/turnings, use fine grit abrasives by hand.
Next, fill any holes, cracks or imperfections with wood putty or filler. Allow proper drying/curing time before sanding flush. Use grain filler products on open-grained woods like oak or mahogany to help achieve an ultra-smooth finish.
Remove dust thoroughly using a brush or vacuum so particles don’t interfere with finish adhesion. Wipe with a tack cloth for final cleaning.
Striving for a mirror-smooth surface allows stains and film finishes to adhere evenly for a smooth coat. But some projects like rustic furniture intentionally retain some wood texture even under finishes for aesthetic reasons.
Sealing with sanding sealer ensures oil-based stains don’t penetrate too deeply and unevenly on certain soft/resinous woods like pine, cherry or cedar. The sealer provides a uniform foundation.
Staining Wood for Custom Color Effects
Wood stains add beautiful coloration while allowing the natural grain to show through. Steps for stain success:
1. Test colors on scrap pieces of project wood to confirm desired hue. Let test pieces fully dry before deciding if color is right. The end tone may lighten as stain dries.
2. Stir oil-based stains before/during use as pigments settle. Water based stains can be used straight from container.
3. Apply using a high-quality brush designed for stains, or lint-free cloth. Maintain a wet edge overlapping strokes slightly to prevent blotchiness. Work stain into grain, but avoid over-brushing in one area.
4. Wipe excess stain off evenly using clean rags or paper towels 5-15 minutes after application. Consistent wiping pressure preserves an even appearance. Allow more penetration time before wiping for a darker result.
5. Apply finish coat like varnish after staining following manufacturer’s dry time recommendations. The finish protects the stain and enhances the wood.
Layering multiple stains expands options. First full-coverage staining with a lighter shade, then additional staining with darker colors allows more control over end results. This works well for “sunburst” effects emanating out from wood grain lines. Applying the same stain repeatedly also progressively darkens the wood.
Painting Wood for Fun Colors
Beyond just natural wood hues, painted finishes allow any color for furniture, crafts and more. Tips for painted success:
Primer helps paint properly bond to raw wood, especially resinous/tannin-rich types like pine or cedar that resist paint adhesion. But very smooth sanded wood may not need primer first.
Sand painted surfaces with 220 grit sandpaper between coats for maximum smoothness. Always sand final coat gently with fine (400+) grit to level brush marks. Remove all sanding dust before adding next layer.
Work in a dust-free area since particles landing in wet paint leave bumps in the cured surface. Cover nearby surfaces from airborne dust settling during application/drying too.
Apply in thin coats using high density foam or china bristle brushes recommended for the paint type. Thin coats level out better than thicker ones. Allow full drying between coats according to manufacturer directions. Multiple thin layers provide a smoother, more durable painted finish than few thick coats.
Consider an enamel undercoat/topcoat for an ultra-durable painted finish. The extra hard surface resists chipping, fading and stains.
Varnishing and Finishing for Protection with Enhanced Beauty
Varnishes and other film finishes protect stained/painted projects while enhancing their beauty through surface gloss, clarity and depth. Considerations when varnishing:
Types: Oil-based varnishes excel at surface build but have stronger odor during application and curing. Water-based varieties pose fewer fume issues with easier cleanup but may require more coats. Choose marine spar varnish for outdoor pieces. Consider rub-on wiping varnish for a hand-rubbed look.
Sheens: Gloss, satin and matte finishes each have aesthetic effects. Gloss offers the clearest, most light-reflective surface. Satin provides some sheen along with muted luster. Matte finishes minimize glare.
Applying: Stir varnish before use to incorporate flattening agents. Use high-quality bristle or foam brushes made for varnish. Maintain wet edge for smooth flow between brushstrokes. Work quickly but avoiding drips or runs.
Sanding: Smooth each coat with 400+ grit sandpaper once fully cured before adding the next layer. Four to six thin coats create a glass-smooth film. Allow at least 24 hours between coats.
Oil and wax (like tung oil) finishes provide some protection while retaining a natural open-grain look. But term “hand-rubbed” traditionally refers to using fine abrasives like rottenstone/pumice between oil coats to fill pores and level the surface. This yields depth and clarity enhancing woodgrain’s natural beauty.
Caring for Finishes to Protect Your Work
The right care preserves the beauty and durability of any wood finish:
Dust often using soft cloth to prevent buildup from sanding fine particles into surface.
Clean with mild soap and water. Avoid abrasive cleaners or pads that could scratch finishes.
Place coasters under glasses/vases to prevent moisture rings or white spots from forming.
Avoid placing in direct sunlight which can cause faster fading and drying/cracking over time.
Apply paste wax helps protect wood surfaces from spills and stains. It cleans off easily with mineral spirits.
Spot repair minor finish damage using the original product. First sand damaged areas, tapered at edges. Then reapply finish to blend repair.
Reapply varnish/oil after several years as older layers wear down from cleaning and use. Scuff sand first before refreshing finish.
With the right supplies, techniques and care, you can achieve stunning wood finishes that properly showcase the natural beauty of wood while protecting projects for lasting durability and enjoyment for years to come.

Frequently Asked Questions
What are some beginner wood finishing mistakes to avoid?
Rushing surface prep and skipping proper sanding often leads to poor finish adhesion and uneven appearance. Also apply finishes only in ideal temperature/humidity conditions per manufacturer directions. And always test products first on scrap wood to ensure compatibility and appearance.
Do I need to sand between oil coats?
Lightly sanding with 400+ grit sandpaper between oil layers helps level out the finish while filling pores for a smooth, blended look. Always wipe away dust before reoiling.
What causes blotchy wood stain results?
Uneven sanding, inadequate surface cleaning, working on poor quality wood or improper application technique can all cause blotchy stain absorption. Using a pre-stain wood conditioner equalizes absorbency. Test staining scrap wood first.
How do I fix a finish damaged by water rings?
Lightly sand the damaged area and taper the edges. Then use touch-up stain and finish products matching your originals to reapply color and sealants. Blend new layers into old finish.
Can I apply water-based finishes over an existing oil-based stain/varnish?
Yes, water-based varnishes and other finishes fully compatible with cured oil-based layers underneath. Just ensure prior finishes are degreased, lightly abraded and dust-free first.
What are signs my finish needs refinishing?
Fading, flaking, cracking, scratching, water marks or wearing through to expose raw wood all indicate existing finish layers have worn down from use/exposure. Complete refinishing renews wood protection and aesthetics.
How long do I need to wait before using a finished piece?
Oil finishes cure fastest in just 1-7 days generally. Sealants, varnishes or paints may take 2-4 weeks to fully harden depending on coats applied. Avoid placing hot, damp or abrasive objects on any finish during its curing timeline.
