Check the wear layer at a vent or threshold to see whether your hardwood is a candidate for refinishing. If the boards are sound, screening (screen-and-coat) can scuff the existing finish and allow a new coat of modern water-based or oil-modified polyurethane with minimal dust. Deep damage usually requires sanding, which today is often done with dust-collection shrouds and HEPA vacuums. Chemical "liquid sanding" and bonding systems exist for low-dust restorations but require careful product following. Dry and cure times vary by product; light walking is often permitted within hours, with full cure typically taking days to a week.

Did you pull up old carpeting and find hardwood underneath? Many older homes hide real wood floors that can be restored instead of replaced. This update explains how to tell if a wood floor can be refinished, the common restoration methods used today, and practical expectations for time and dust.

Can the floor be refinished?

Start by checking the wear layer - the wood above the tongue-and-groove joint. On solid plank floors that wear layer is full thickness; on engineered flooring it is the top veneer. You can often see the wear layer at a removable register vent, at a transition strip, or at a closet threshold.

How many times the floor can be refinished depends on the thickness of that wear layer and the type of floor (solid vs engineered). Thicker wear layers let you sand deeper. If you can't see thickness easily, remove a vent or an existing threshold for a look.

Screening (screen-and-coat): a low-dust refresh

If the finish is worn but the wood itself is sound and there are no deep scratches or cupping, screening and recoating is a common professional method. A floor technician uses a low-speed buffing machine with an abrasive pad to scuff the existing clear coat. That prepares the surface so a new coat of finish (typically a water-based or oil-modified polyurethane today) will bond.

Steps:


  • Clean and vacuum the floor thoroughly.


  • Screen with a proper pad attached to a buffing machine.


  • Vacuum and tack with a microfiber or cloth dampened with an appropriate cleaner (avoid excess solvent).


  • Apply the finish with a lambswool applicator or roller and back-roll as needed.


Most modern water-based finishes dry faster than older oil-based urethanes; many products advertise walk-on times measured in hours and lighter traffic within a day, with full cure in about a week. Exact times vary by product and conditions; follow the manufacturer's label. 1

When you need more than screening: sanding or repair

If boards are deeply scratched, stained, or you need to remove old finishes, a full sanding may be required. Today's sanders commonly use a dust-collection shroud and HEPA-rated vacuums to dramatically reduce airborne dust compared with open sanding.

Chemical methods and low-dust systems

There are also chemical stripping or "liquid sanding" products and bonding systems designed to remove or modify the existing finish without full mechanical sanding, and then accept a new finish. These systems can cut dust and speed turnaround, but they require following product instructions closely to get a reliable bond. 2

Expectations for use

After recoating, you can often walk on the floor with care within hours to a day, but avoid heavy furniture and rugs until the finish has cured per the product instructions (commonly several days to a week for full hardness).

When to call a pro

Call a flooring professional if you're unsure about wear-layer thickness, if the floor has structural problems, or if you need a guaranteed dust-minimizing sanding setup.

Modern finishes and dust-control tools let many homeowners refresh hardwood with far less mess than in the past. Inspect the wear layer, decide between screening or sanding, and pick a finish whose drying and curing times match your schedule.

  1. Confirm typical wear-layer thickness ranges for engineered flooring veneers (common thicknesses and how many times they can be sanded).
  2. Verify current typical dry-to-walk-on and full-cure times for popular water-based polyurethane finishes.
  3. Confirm terminology and availability of chemical "liquid sanding" systems and their common product names/claims.

FAQs about Restoring Hardwood Floors

How can I tell if my hardwood is solid planks or engineered?
Look at an exposed edge - under a register vent or at a threshold. Solid planks are full thickness all the way through; engineered boards show a thin top veneer over layered backing. If you can't access an edge, a flooring pro can confirm.
What’s the difference between screening and sanding?
Screening (screen-and-coat) lightly abrades the existing finish to accept a new coat and produces minimal dust. Sanding removes finish and some wood, addressing deep scratches or stains but historically created much more dust (modern sanding uses dust-collection systems).
How soon can I walk on a newly recoated floor?
Many modern water-based finishes allow light foot traffic within hours and normal use after 24-48 hours; full hardness typically develops over several days to a week. Always follow the manufacturer's guidance for the specific product you use.
Are dustless sanding systems really dust-free?
No sanding system is perfectly dust-free, but using sanders with shrouds plus HEPA-rated vacuums greatly reduces airborne dust compared with uncontained sanding.
When should I hire a professional?
Hire a pro if you can't determine wear-layer thickness, if floors have structural issues, or if you want minimal dust and a guaranteed finish application.
