The short answer by floor type
| New floor | Paint walls first? | Why |
|---|---|---|
| Luxury vinyl plank (LVP) or laminate | Yes | Clean, quick install; paint drips on vinyl are a pain to remove and easy to scratch out of |
| Prefinished hardwood or engineered | Yes | The floor arrives finished; protect it once, after the messy work is done |
| Tile | Yes, with a final touch-up after | Tile setting splashes thinset and grout low on the wall; plan a touch-up of the bottom foot |
| Carpet | Yes, always | Carpet goes in last of all; paint spilled on carpet is the worst floor to clean |
| Site-finished hardwood (sanded in place) | Prime and first coat yes, final coat after | Sanding dust settles on wet or fresh paint; the finish needs a dust-free room |
| Refinishing existing hardwood | After the floor, or before with a final coat after | Same dust problem; the last coat of polyurethane wants the room empty and closed |
The full sequence in a room
- Drywall finished and primed. The mud has to be fully dry before primer; the waits are in how long drywall takes to dry.
- Ceiling, then walls, two coats. On the bare subfloor, with a drop cloth for the heavy drips. Run the wall paint an inch or so below where the top of the baseboard will land.
- Flooring. Installed against painted walls, with the expansion gap at the edge that the baseboard will hide.
- Baseboards and door casing. Ideally primed and painted on sawhorses before they go up, so only the nail holes and joints need work on the wall.
- Fill, caulk, final coat on the trim. Caulk the gap between the top of the baseboard and the wall, fill the nail holes, then the last coat on the trim with tape or a shield over the new floor.
- Touch-ups. Wall scuffs from the flooring crew and the trim install, with paint saved from the same can.
The caulk line is why the order works. The bottom inch of the wall is hidden by the baseboard, and the joint between baseboard and wall is closed by a bead of caulk that gets painted with the trim. So the wall paint never has to meet the floor at all, and the painter never has to cut a clean line against new flooring. Shoe molding or quarter round, if you use it, goes on last and gets painted or stained before it is nailed down.
The arguments for painting after the floor
Some painters prefer to go last, and they have a point in a few cases. If the floor install is rough on walls, as tile and site sanding are, every scuff becomes a touch-up anyway. If the old baseboards stay in place and the floor goes in up to them, the painter has to come back for the trim regardless. And some owners would rather do one painting visit at the end than two. The fix is the same in each case: do the ceiling and the first wall coats early, protect the new floor with rosin paper or a breathable floor protector taped at the seams, and leave the last coat on the walls and trim for after.
What does not work is painting after the floor with nothing on it. Plastic sheeting slides under a ladder, and a can kicked over on new LVP or prefinished oak is a repair, not a wipe. Cardboard or a proper floor protector is cheap next to replacing two planks from a discontinued lot, which is the risk covered in how much flooring to order.
Scheduling the two trades
| Step | Typical time for a room | Waits on |
|---|---|---|
| Prime and two coats, walls and ceiling | 1 to 2 days | Dry drywall; a few hours between coats |
| Flooring, floating LVP or laminate | 1 day | Dry paint; the boxes acclimated in the room first |
| Flooring, tile | 2 to 3 days plus grout cure | Dry paint, a flat subfloor; no walking until the thinset sets |
| Flooring, site-finished hardwood | 3 to 5 days including coats of finish | Painting done except the final coat; the room closed to traffic |
| Baseboard and trim | Half a day to a day | The finished floor |
| Caulk, fill and final trim coat | Half a day plus drying | The trim installed |
Most flooring needs its boxes sitting in the room for a few days before install, so order it to arrive while the paint is still going on, not the day the painter leaves. Paint quantities for the walls, ceiling and the trim are in paint quantities explained, and if the room will be slept in soon after, a zero-VOC interior paint keeps the smell out of the bedroom; what the labels actually mean is in low-VOC and non-toxic paint.
Keep a quart for the end
Every renovation ends with touch-ups: a scraped corner from the flooring crew, a nick where the baseboard was nailed, a mark from the appliance delivery. Keep a labeled quart of each wall color and the trim, with the brand, color name and sheen written on the lid, and put the touch-ups on the punch list rather than asking for them as you go. Paint the room on the bare subfloor, put the floor in, then the trim, caulk and the last coat, and the only line the painter ever has to cut against your new floor is the bottom of the baseboard, with tape under the brush.
