The 36, 50 and 80 Grit Sequence
A full sand runs through a sequence, commonly 36 then 50 then 80 grit, with each pass removing the scratch pattern left by the one before. Skipping a grit to save an hour leaves deeper scratches that the finish then magnifies, and those show up under daylight rather than under work lights.
Screen and Recoat Against a Full Sand
If the finish is worn but the wood underneath is not damaged, a screen and recoat abrades the existing surface and adds a fresh coat without removing wood. It is faster, cheaper and leaves the floor thicker. We recommend it wherever the floor genuinely qualifies, because it preserves sandings for later.
Dust Containment at the Sander
Dust is collected at the machine rather than chased afterwards, with containment at doorways and controlled airflow. Nothing captures every particle, and any contractor claiming otherwise is overselling it. What good containment does deliver is a house that stays livable and a neighboring unit that is not coated.
How Long a Refinish Keeps You Off the Floor
Timing depends on the finish system, not on the size of the room. Waterborne products allow foot traffic soonest, oil-modified takes longer, and every system needs longer again before rugs and heavy furniture return. We give the actual schedule for the product going down, coat by coat, in writing.
Waterborne, Oil-Modified and Hardwax Oil
Waterborne finishes dry fast and stay clear, oil-modified polyurethane ambers over time and is very durable, and hardwax oil sits in the wood and can be spot-repaired without recoating a whole room. Each suits a different situation, and the right one depends on traffic, timeline and how the floor will be maintained.
Finishes Legal Under the Air District Coating Limit
The South Coast air district caps wood coatings at 275 grams per liter, and that limit binds the contractor applying the product, not only the manufacturer selling it. We specify from products that comply, so there is no discovery midway through a job that the intended finish cannot legally be used here.
Choosing a Sheen You Can Live With
Sheen changes how much a floor shows. Higher gloss reflects more light and reveals every fleck of dust, footprint and minor scratch, while satin and matte hide more and read as more contemporary. In rooms with strong daylight the difference is dramatic, so we look at samples in the actual room.
Refinishing Room by Room While You Stay
Most refinishing jobs can be phased so the household keeps part of the house throughout, with sealed-off work areas and a sequence agreed in advance. It takes longer overall than emptying the place, but for an occupied house or an occupied building it is usually the difference between doable and not.
Cure Time Against Dry Time
Dry means the surface is no longer tacky. Cured means the finish has reached full hardness, which takes considerably longer. Putting rugs down or sliding furniture across a floor that is dry but not cured is the most common way a brand new finish gets damaged in its first month.
Edges, Corners and Closets
A drum sander cannot reach the perimeter, so edges, corners, closets and stair landings are worked with an edger and by hand. Blending that perimeter into the field is the part of the job that separates a good refinish from an obvious one, and it is where the time goes.
