Wood Finishes

What wood finish options does SENTIENT offer?

SENTIENT offers hardwax oil, polyurethane, water-based clear coats, lacquer, shellac, stains and charcoal finishes, bleach and whitewash treatments, distressed techniques, and resin and epoxy fills for river tables and void filling. Every finish is hand-applied in our Brooklyn workshop and chosen based on how the piece will be used, where it will live, and how much maintenance the client prefers. Browse all finish options.

What is hardwax oil and why does SENTIENT use it for live edge?

Hardwax oil is SENTIENT’s most common finish for live edge furniture. It is a penetrating finish that soaks into the wood rather than sitting on top, giving a natural look and feel while providing everyday protection. The oil cures by oxidative polymerization, forming a protective barrier, while the wax adds surface resistance and a subtle sheen. Hardwax oil is food-safe once fully cured, refreshable without stripping, and lets the wood breathe and develop character over time. It fails gracefully, meaning scratches blend in rather than flaking or peeling.

What is the difference between oil finishes and film finishes?

Oil finishes like hardwax oil penetrate the wood and protect from within. They feel natural to the touch, are easy to refresh, and let the wood develop patina. Film finishes like polyurethane, lacquer, and water-based clear coats build a protective layer on top of the wood. Films offer stronger moisture and abrasion resistance, making them better for high-traffic commercial surfaces. The trade-off is that film finishes are harder to spot-repair and may require full sanding to refinish. SENTIENT recommends oil for residential live edge work and film for hospitality and commercial applications.

How do I choose the right finish for my furniture project?

Start with how the piece will be used. For residential dining tables and live edge work where a natural feel matters, hardwax oil is our most common recommendation. For high-traffic commercial surfaces like restaurant tables and hotel lobby furniture, polyurethane or lacquer provides maximum protection with minimal maintenance. If preserving a light wood color is the priority (especially on maple or ash), water-based finishes minimize ambering. For design-driven color work, stains and bleach treatments offer a wide range of tonal options. Our team will recommend the right system during the design phase.

Are SENTIENT wood finishes food-safe?

Yes. SENTIENT’s hardwax oil finishes are food-safe once fully cured, making them appropriate for dining tables, kitchen surfaces, and restaurant furniture. The oil-wax blend creates a sealed surface that resists moisture and daily contact with food and drinks. Film finishes like polyurethane and lacquer are also food-safe once cured, as the solvents fully evaporate during the curing process. We will recommend the right food-safe option based on your project’s use case and maintenance preferences.

What sheen and gloss levels are available?

SENTIENT offers finishes across the full sheen spectrum, from dead matte to high gloss. Gloss levels are measured on a 60-degree gloss meter: matte reads below 10%, satin falls between 25% and 40%, semi-gloss between 41% and 69%, and high gloss above 70%. Most SENTIENT furniture uses a satin to low-sheen finish, which balances warmth and visual depth without showing every fingerprint. Higher gloss is available for statement pieces and formal settings, though it requires more meticulous surface preparation and shows wear more readily. The flattening agents used to control sheen do not affect the finish’s durability.

How do stains and charcoal finishes work?

Wood stains shift the color of the wood while preserving grain visibility. Pigment-based stains sit in the pores and create more contrast on open-grained species like oak and ash. Dye-based stains penetrate more evenly for uniform color. SENTIENT’s signature charcoal finish is a multi-layer technique that creates deep, rich black tones while maintaining the natural grain texture. Red oak is particularly well-suited to staining because its open pore structure accepts color deeply and evenly. Learn more about stains and charcoal finishes.

What is grain filling and when is it needed?

Grain fillers are used to level the open pores of ring-porous woods like oak and ash before applying a film finish. Without filler, the pores remain visible as tiny craters under the topcoat, which prevents achieving a smooth, mirror-flat surface. Grain filling is typically needed when the design calls for a high-gloss finish on an open-grained species. For most satin and matte finishes, filling is not necessary since the open pores are part of the wood’s natural texture. Our finishing team will specify whether grain filling is needed based on the species and desired sheen level.

Can wood finishes be repaired or refreshed?

Yes, and this is one of the real advantages of solid wood furniture. Oil-finished surfaces like hardwax oil can be refreshed by lightly sanding the affected area and reapplying oil. Minor scratches often blend out with a simple re-oiling. Film finishes like polyurethane and lacquer may require spot repair for small scratches or full sanding and refinishing for deeper damage. Because SENTIENT uses solid wood throughout (not veneer), the surface can be sanded and refinished multiple times over the life of the piece. See our care and maintenance guide.

Can I change the finish on my furniture later?

Yes. Because SENTIENT furniture is built from solid hardwoods, the surface can be sanded down and refinished with a different system. You could start with hardwax oil for a natural look and later switch to polyurethane for more protection, or add a stain to change the color entirely. This is one of the fundamental advantages of solid wood over veneered or composite furniture: the material supports multiple refinishing cycles over its lifetime.
