Wood primer and millwork finishing 

Somewhere in a lab, a chemist is trying to outperform a bug. The bug is still winning.

Shellac has been used as a finish and sealant for centuries and nothing synthetic has come close to replacing it for sealing raw and unknown wood substrates. The alcohol carrier that gives it that sharp initial smell flashes off within minutes — what’s left behind is one of the most natural and effective sealers in existence. It’s a step most contractors skip because the cleanup adds time and the material costs more. But it’s the difference between a finish that holds for years and one that starts showing tannin bleed or discoloration within months.

Preparation matters

The finish is only as good as what’s underneath it.

Primer is sanded smooth using the Festool sanders and dust extraction system paired with Granat abrasives — a self-sharpening, non-clog material that keeps cutting cleanly while allowing heat to dissipate from the surface. Heat buildup from a clogged disc doesn’t just slow things down, it can burn or glaze the material instead of abrading it cleanly. For contoured surfaces and moldings, Granat PROfile foam-backed pads conform directly to the shape. Polyester fillers are used for any repairs. On the spray side, Graco FFLP tips run at up to 50% lower pressure — delivering the softest, most consistent fan pattern available in airless spraying.

Paint selection

The closest thing to a factory furniture finish from a paint off the shelf.

The standard for any trim, woodwork, or cabinetry is Sherwin-Williams Gallery Series water-based urethane trim paint. Formulated for spray application, it self-levels exceptionally well and holds up where other paints in this category create micro-texture or start showing wear ahead of schedule. The cost per gallon is higher upfront — but considerably less expensive than refinishing ahead of schedule.
