Paint & Finishing Guides
Paint & Finishing
Primer selection, paint spraying, furniture makeovers, and deck staining — finishing techniques that look professional, not good enough.
Paint is 90% preparation, and the difference between a finish that looks professional and one that looks DIY is almost always what happened before the color went on. Our painting guides lead with surface prep — choosing the right primer, sealing, and sanding — because that's where finishes are won or lost.
We cover the decisions that trip people up: latex versus oil primer, airless sprayer setup, furniture and cabinet makeovers, and the deck staining that actually lasts through weather.
Expect specifics over enthusiasm — the right primer for the surface, the right tip for the sprayer, the right order of coats. A finish that lasts is the only kind worth doing.

Frequently Asked Questions
Latex or oil primer — which do I need?
Oil primer is for sealing stains, bare wood, and adhesion over glossy or problem surfaces; latex primer is for general drywall and previously painted surfaces. If you're covering stains or tannin bleed, oil wins — otherwise latex is easier to work with and lower-VOC.
What pressure and tip should I use for an airless sprayer?
Start at the low end of the sprayer's recommended range and test on scrap — common starting points are 1,500–2,000 PSI for latex with a .015–.017 tip for trim and doors, .017–.019 for walls. Adjust until the fan is even with no tails at the edges.
How do I get a furniture paint job to last?
Sand, clean, and prime for adhesion, then use paint suited to the material and a topcoat for high-wear surfaces. Most peeling and chipping comes from skipping the prep or using the wrong product for the substrate, not from the paint itself.
How do I stain a deck so it lasts?
Clean and brighten the wood first, let it dry fully, and apply stain in weather conditions the product specifies. Penetrating stains last longer than film-forming ones because they soak in instead of peeling, but they still need reapplication every couple of years.
