Polyurethane, varnish, lacquer and shellac topcoats: choosing, applying and recoating.
Reclaimed wood looks best when the finish protects it without filling its saw marks, dents, nail holes, and uneven grain. For most projects, the best balance is a matte hardwax oil or a matte water-based polyurethane. The right choice depends on whether you value the most natural texture or the Read more
The best finish depends on how the rounded edge will be used For most indoor projects with rounded edges, a wipe-on oil-and-varnish finish or a brushed water-based polyurethane is a practical choice. Rounded edges are harder to coat evenly than flat faces: finish runs off the curve, and a sharp Read more
For a wood surface exposed to kitchen grease, the best general-purpose finish is a fully cured film finish: water-based polyurethane for most indoor projects, or oil-based polyurethane when maximum water and solvent resistance matters more than drying speed and color. Penetrating oils are easy to refresh, but they do not Read more
Choosing a Finish for Cedar Siding The best exterior finish for cedar siding is usually a high-quality, penetrating, water-repellent stain—especially a semi-transparent stain that contains mildewcide and ultraviolet protection. It protects the wood without forming a thick film that can peel across large siding surfaces. That is not the only Read more
Ash is naturally pale, open-grained, and easy to darken by accident. The best clear finish for keeping it light is usually a water-based clear polyurethane, preferably labeled “crystal clear,” “non-yellowing,” or “water-clear.” It adds protection without the amber cast produced by most oil-based finishes. That choice is not universal. A Read more
A frequently handled banister needs more than an attractive finish. Hands deposit skin oils, dirt, and cleaning chemicals on the wood, while rings and carried objects create repeated abrasion. The best practical choice for most indoor stair railings is a clear, hard film finish—usually water-based polyurethane—applied over properly prepared wood. Read more
Best Finish for Protecting a Wood Bathroom Vanity For most wood bathroom vanities, the best all-around finish is a high-quality water-based polyurethane, preferably a product labeled for floors, cabinets, or heavy interior use. It creates a clear, hard film, resists soap and toothpaste, and does not add much color to Read more
Wood exposed to sun, rain, and seasonal movement needs a finish that can do more than make it look good. The wrong coating may crack, peel, or turn cloudy within a year. Spar varnish and exterior polyurethane are both used outdoors, but they are not interchangeable in every job. The Read more
When a wood finish has to dry quickly, shellac and lacquer are usually the first choices. Both can be recoated far sooner than oil-based varnish or polyurethane, but they behave differently on the bench. Shellac is easier to repair and more forgiving over unknown surfaces. Lacquer builds a smoother, harder Read more
For most interior wood projects, “varnish” and “polyurethane” are not truly opposite finishes. Polyurethane is a resin used in many modern varnishes. In the store, though, varnish usually means a traditional oil-based or water-based clear finish, while polyurethane usually means a tougher film finish labeled specifically for floors, furniture, or Read more
