Priming and painting wood for a smooth, durable painted finish.
Good new paint starts with the old paint. If the existing coating is dirty, glossy, loose, or contaminated with grease, the new finish may peel, blister, or show every dent underneath it. Preparing previously painted wood is not difficult, but it is more than giving the surface a quick scuff. Read more
Routed edges are easy to make look good and surprisingly easy to make look worse than a square edge. The cutter leaves a clean profile, but it also creates end grain, inside corners, sharp transitions, and sometimes small ridges from router chatter. Paint will highlight every one of those defects.

MDF has a smooth face but thirsty, porous edges. If you apply primer directly to unsealed MDF, the faces may look fine while the edges turn fuzzy, swollen, or uneven. Paint can also dry with different sheen and texture from one area to another. Sealing MDF before priming is mainly Read more
A seamless paint finish starts before the paint goes on. Wood filler must be mixed to the right consistency, pressed firmly into the defect, and sanded without leaving a soft or visible patch. Poor preparation commonly shows up as sink marks, flashing, pinholes, or a different sheen around every filled Read more
MDF edges are more absorbent and softer than the faces. If you paint them without sealing first, the edge drinks primer, raises fuzzy fibers, and often looks rougher after every coat. The fix is not simply more paint. A smooth result comes from hardening and filling the edge before applying Read more
How to Fill Nail Holes in Wood Before Painting Small nail holes are easy to fill, but they are also easy to make visible. Paint will not hide a shallow dent, a dark shadow, or a ring of raised wood around the fastener. The best results come from treating the Read more
The short answer For painted projects, hardwood is not automatically better. Softwood is usually the better buy for large trim, shelving, utility furniture, and outdoor projects where low cost and easy machining matter. Hardwood earns its price when you need a harder surface, cleaner edges, better dent resistance, or a Read more
Paint adhesion depends more on preparation than on the paint itself. Wood can look clean and still contain sanding dust, wax, silicone, resin, or mill glaze that prevents a coating from gripping. A good preparation job creates a clean, slightly keyed surface, removes anything that can bleed through, and gives Read more
A distressed painted wood finish is meant to look worn, not neglected. The convincing version has variation: exposed edges, a few darker recesses, uneven color, and wear in places that would realistically receive handling. The process works on furniture, trim, shelving, crates, and other projects made from solid wood or Read more
Why Wax Causes Problems Under Paint Wax is a poor paint base because it remains soft and water-repellent. Paint may appear to stick at first, then peel, fisheye, crack, or lift when the wood expands and contracts. Sanding alone usually does not solve the problem: it can flatten the surface Read more
