Dull, scuffed timber floors can make a whole room feel tired, but it doesn’t always mean you need to strip everything back to bare timber.
If the damage is in the coating rather than the timber itself, you might be able to bring your floors back with a thorough clean, a light sand and a fresh coat. It takes a fraction of the time, mess and cost of a full sand, but only if the prep is done properly.
In this guide, we'll help you work out whether your floor is ready for a recoat, then walk through how to clean and prep timber so your new coat bonds properly and looks its best. If your floor needs a full sand back, our How to Sand a Floor guide covers that process step by step.
Quick Answer: How Do You Prep Timber for a Recoat?
To prep a timber floor for a fresh coat:
- Check that the wear is in the finish, not the timber
- Identify what finish is currently on the floor
- Deep clean and remove any polish, wax or residue
- Lightly abrade the surface so the new coat can grip
- Remove every trace of dust
- Test a small area, then recoat
Recoat or Full Sand? How to Tell
Before you buy anything, take a close look at your floor.
A recoat is usually enough when:
- The finish looks dull, patchy or worn in high-traffic areas, but the timber underneath hasn't been exposed
- Scratches are light and sit in the coating rather than the timber
- Oiled or hard wax oil floors look dry or tired, as many oil systems are designed to be maintained this way
- You want a quick refresh before selling, moving in or the end of a lease
You'll need a full sand when:
- Wear has gone through to bare or greyed timber
- There are deep scratches, dents or gouges in the timber itself
- There's water damage or black staining
- The coating is peeling, flaking or lifting
- You want to change the stain colour
On oiled floors, a simple check is to place a few drops of water on a high-traffic area. If the water beads on the surface, the finish is still protecting the timber. If it soaks in or darkens the timber quickly, the floor needs some maintenance.
Know What's on Your Floor First
Your new coat needs to be compatible with the existing one. Put the wrong product on top, and it may not bond properly, which can lead to peeling, patchiness, or a finish that wears through quickly.
Most timber floors are finished with one of two types of product:
- Polyurethane: a hard protective film that sits on top of the timber, available in water-based and solvent-based versions
- Oil or hard wax oil: soaks into the timber and gives a more natural, low-sheen look
If you know who finished your floors or what product was used, that's the easiest starting point. If you're not sure, don't guess. Contact our team, and we can help you work out what's on your floor and recommend the right product.
Step 1: Deep Clean the Timber
Start by clearing the room completely and vacuuming thoroughly, paying attention to edges, corners and the gaps between boards.
Next, clean the floor with a product designed for your floor. Lacquered and oiled floors need different cleaners, and using the wrong one can leave residue behind or damage the existing finish. You'll find suitable options in our Lacquered Floor Cleaner and Oiled & Waxed Floor Cleaner ranges.
Pay attention to contaminants that are known for causing adhesion problems:
- Floor polishes and "shine" products
- Wax build-up
- Silicone-based sprays, including some furniture polishes and household cleaning sprays
- Grease and cooking residue in kitchens
These can be hard to spot, but they can cause a new coat to bead, separate or peel.
Once the floor is clean, let it dry completely before moving on.
Step 2: Lightly Abrade the Surface
The goal here isn't to sand back to timber. You're simply scuffing the existing finish so the new coat has something to grip. A coat applied over a smooth, glossy surface is far more likely to fail.
For polyurethane floors, a floor buffer fitted with sanding screens is the most efficient way to abrade the main area evenly. Use an orbital sander for the edges and any spots the buffer can't reach. You'll find buffing screens and orbital sanding discs in our abrasives range.
For oiled and hard wax oil floors, the process can be different. Depending on the product system, a thorough clean may be all that's needed before a maintenance coat. Always check the manufacturer's directions for your oil.
Whatever finish you're working with, be careful not to cut through to bare timber. Bare patches absorb coating differently from the surrounding floor and can leave it looking uneven.
Step 3: Remove Every Trace of Dust
Any dust left on the floor will be trapped in your new coat for good, so give it a thorough clean.
Work from the top down. Vacuum window sills, the tops of skirting boards and any ledges first, then move on to the floor itself. You may need several passes to get it all.
Finish with a final wipe of the floor using a method suited to the coating you're about to apply, and make sure the floor is completely dry before you start coating. Then shut the windows, turn off fans, and keep people and pets out so fresh dust doesn't settle before you start the next step.
Step 4: Test, Then Recoat
Before coating the whole floor, do a test patch in an inconspicuous spot, such as inside a wardrobe or under where a couch normally sits. Let it cure, then check that it has bonded well and that you're happy with the look.
When you're ready, apply the new coat following the manufacturer's directions. Use a brush around the edges and a short-haired roller for the main area, working along the grain. Thin, even coats give the best result.

The Same Rule Applies Outdoors
Decks and exterior timber follow the same principle. A regular clean and re-oil is far easier, and far cheaper, than waiting until the timber is grey and weathered enough to need a full sand.
Clean the deck with a dedicated deck cleaner, let it dry completely, then apply a fresh coat of exterior oil. You'll find everything you need in our Exterior Wood Oil & Cleaner range.
