Hard maple hall table. Apron-and-leg construction, through-tenon aprons. Interior BC home, baseboard heat, a humidifier that runs October through April. Natural light from one window.
Every finishing decision for this piece was made before the first sandpaper touched it. That's the sequence. Everything else is just execution.
Before You Open the Sandpaper
Most finishing problems start here — when this stage gets skipped. You grab the sandpaper, sand to 220, raise the grain, sand again, reach for a finish, and then figure out what finish you're using while the piece is in front of you. That's backwards.
For this table:
Use case. A hall table sees keys, mail, the occasional glass. It's not a dining table. Film hardness isn't the governing requirement. Repairability and appearance matter more than armor. The failure modes to avoid are water rings and a surface that reads as finished rather than as wood. This points toward a penetrating oil or a thin film system. Not high-build polyurethane.
Species. Hard maple, which means water-based topcoats only if keeping the wood light. Oil-based poly on maple goes yellow. Irreversibly. The owner wants maple that reads as maple. Water-based system confirmed.
Shop conditions. March in the BC Interior. The shop cycles — heat on, heat off, overnight lows around 5°C. Water-based topcoat requires 13–15°C through the first four hours of cure. This is a scheduling constraint, not a problem. Heat the shop before mid-morning. Apply finish before noon. Don't start a finishing session at 3 PM.
System. Dewaxed shellac seal coat. Water-based poly, satin sheen, wipe-on application, three thin coats. No stain on maple. No wax. Write this down. Do not revisit it at the finishing station.
Surface Prep
Sand to 180. Not finer. Water-based grain raising makes 220-grit scratches visible under the finish, and you're raising the grain before the first coat anyway — so you'll sand to 220 then. No point chasing a 220 surface twice.
Work with the grain. Random-orbit swirls on hard maple read through water-based finish. The finish doesn't hide them. It locks them in.
Raking light before any finish goes on. Work light at 15–30° off the surface, low and raking, across every face. You're looking for cross-grain scratches, orbital swirl marks, planer snipe at board ends, old glue squeeze-out that was sanded over (shows as a ghosted patch with different light absorption). Fix everything the raking light finds. The finish will not cover any of it. The finish will make it permanent.
Hard maple has closed grain — no pore-filling decision needed. The surface is the surface.
Grain raise: wipe the surface with a damp cloth, let dry completely (two to three hours in a warm shop), sand flat with 220. Pre-raising the grain means the first coat of waterborne finish doesn't do it while loaded with product. Cold-shop note: below 10°C the drying time doubles. Do the grain raise in the morning, let it dry over the warm part of the day.
Pre-Assembly Finish
Before glue-up, seal the interior apron faces. Dewaxed shellac, 1.5–2 lb cut, one coat. These surfaces are fully accessible now. Post-assembly, the corners are tight. The shellac prevents glue squeeze-out from staining the maple at the interior joints and gives the interior a finished appearance. It's a 20-minute operation. Do it.
Cure 30 minutes. Glue up.
After Glue-Up
Give PVA a full 24 hours at working temperature before any stress on the joints. Don't start sanding the assembled piece after an afternoon glue-up. Come back in the morning.
Raking light check on all exterior surfaces. Look for squeeze-out haze, cross-grain sanding scratches from leveling joints, any gaps or high spots. Gaps and high spots are joinery problems — fix them before sandpaper. Sand exterior to 180. Raking light again. Grain raise. Sand 220.
The Finishing Sessions
Session 1, seal coat. Heat shop to 15–18°C, let it stabilize for 30 minutes. Dewaxed shellac on all exterior surfaces. Cure 30 minutes. Sand with 320 to remove nibs. Wipe clean.
Sessions 2 and 3. Wipe-on water-based poly. Small amount poured into a shallow dish. Lint-free cotton cloth — T-shirt material works; microfiber tends to leave a pattern. Wipe with the grain, light pressure, thin coverage. The coat will look like almost nothing has been applied. That's correct. Don't compensate by adding more. Cure fully (4 hours minimum in a cool shop). Sand with 320, remove dust, proceed.
Session 4, final coat. Same procedure. Do not sand after this coat. The surface of this coat is the surface of the piece. Slow down. Even, consistent strokes. Let dry 4–6 hours before handling.
The 28-day window: water-based poly is functional but not fully cured for a month. No wax. Nothing heavy on the surface. Note this in the documentation package.
Documentation
One page leaves the shop with the piece: species and its character, finish type and care instructions (damp cloth, no silicone-based furniture polish, no oil sprays), a movement note explaining the slotted clips, and your contact information.
The piece you built will exist for decades. Be reachable.
Use case before sanding. Surface work under raking light. Grain raise before the first coat. Pre-assembly shellac on inaccessible surfaces. Heat the shop before you start. Thin coats, full cure time, no shortcuts on the final coat. Documentation before delivery.
A well-finished piece looks like wood that's been protected, not wood that's been coated. The figure reads. The color is right. You can see the grain texture. If you can see the finish, something went wrong.
That's the sequence. It wasn't complicated. You just had to run it in order.
