Assessing Your Hardwood Floors for Painting
Before deciding on a paint color or investing in supplies, take some time to carefully inspect your hardwood floors. This will help you identify any problem areas to address so your painted floors turn out smooth and durable.
Look for:
- Scratches or gouges – Deep scratches and dents will likely still show through paint, so you’ll need to fill them properly before painting. Use a wood filler that matches the color of your floors.
- Warping or cupping – Severely warped or cupped boards will need to be replaced or sanded down before painting.
- Loose boards – Secure any loose boards with flooring nails/screws so they don’t creak or pop up later.
- Wax, grease stains, or residue – Paint won’t adhere well to waxy or oily surfaces. These need to be removed completely.
- Existing paint or finish – For best adhesion, you’ll need to sand down the previous finish before painting.
- Wood type/condition – Soft or porous woods like pine may require sealing for the paint to cure properly. Avoid painting over rotted or water-damaged boards.
Once you understand the condition of your floors, you can determine how much prep work is needed and decide if DIY painting is feasible or if it’s best left to the pros.
Choosing the Right Paint and Topcoat for Hardwood Floors
The specific paint and topcoat (polyurethane) products you choose will depend on the look you want, where the floors are located, and how much foot traffic they receive. Here are the main factors to consider when selecting products:
Sheen level – Satin or semi-gloss are common choices for hardwood floors. Glossier sheens make colors appear richer but show scuffs more easily. Matte is good for hiding imperfections but can look dull on floors.
Color – For a natural wood look, opt for wood floor paint tinted to match your existing tone. For a change, choose any solid color your heart desires – light colors open up small spaces.
Durability – High-traffic areas and kitchens need an extremely durable floor paint formulated for wear resistance. Check product specs before buying.
Ease of application – Look for polyurethane finishes that self-level and flow out well. Water-based or oil-modified options tend to brush on more smoothly.
Test paint swatches and samples on a board first to ensure you like the color and finish before purchasing.
Preparing Hardwood Floors for Painting
Proper prep is crucial for getting flawless, lasting results painting hardwood floors. Plan on devoting several hours to these key steps:
Deep Cleaning the Floors
Grease, wax, dirt, and dust need to be removed or paint won’t properly adhere.
- Sweep, then use a mop or scrub brush with a degreasing cleaner. Rinse well and allow to fully dry.
- For heavy wax buildup, use a wax stripper. Follow all directions for application and ventilation.
Fixing Imperfections
- Fill any cracks, holes, or deep scratches with wood filler. Let dry completely and sand smooth.
- Hammer down popped nails and replace severely warped boards if needed.
Sanding Off the Existing Finish
This roughs up the surface for better paint adhesion.
- An orbital sander with 80-100 grit paper works well for removing previous finishes.
- Sand uneven boards smooth. Sweep away all dust when finished.
Priming the Floor
Primer improves paint coverage and ensures it bonds tightly to the bare wood.
- Apply oil-based or shellac-based primer by brush, roller, or paint sprayer.
- Cover all areas fully, letting primer dry as directed before painting.
With the prep work complete, your hardwood floors will be ready for their color transformation!
How to Paint Hardwood Floors
Follow these steps for flawless painted wood floor results:
1. Prepare the Room
- Remove all furniture and debris from the room. Roll up rugs and move them elsewhere.
- Clean baseboards, trim, and walls located near the floor’s surface to prevent dust sticking to fresh paint.
- Open windows and use fans or ventilation to ensure airflow and help paint dry faster.
2. Tape Off Areas
- Use painter’s tape to cover baseboards, door trim, and any surfaces you don’t want painted.
- If taping off an entire room, run tape along the borders where floor meets the walls.
3. Apply Floor Paint
- Stir the paint before and periodically during use to keep pigment well incorporated.
- Pour paint into a paint tray or bucket to use as your reservoir for dipping a roller cover into.
- Use an extension pole and high-density roller sleeve designed for smooth floors. Load the roller with paint, then roll back and forth to distribute paint evenly across the floor.
- Maintain a wet edge as you go to prevent lap marks and visible transitions between painted/unpainted areas.
- Work in 3-4 foot sections. Let the first coat dry 4-6 hours before applying a second coat.
- For best durability, apply at least 2-3 thin coats rather than 1 thick coat.
4. Apply Polyurethane Topcoat
Once the paint has dried for 24 hours, protect it with 3 coats of water-based polyurethane:
- Lightly sand painted floors with 220 grit sandpaper to “degloss” and help the topcoat bind.
- Vacuum up all dust. Use a damp cloth to pick up any remaining dust.
- Using a high quality brush, roller, or painter’s pad, apply polyurethane finish with the wood grain.
- Allow each coat to dry fully before adding the next (2-3 hours).
- After the final coat, avoid walking on the floors for 24 hours.
5. Remove Tape and Reassemble Room
- Carefully pull up all painter’s tape once the topcoat is completely dry.
- Replace any furniture, rugs, and decor.
With these steps finished, you can enjoy walking on your freshly painted, polished hardwood floors!
FAQs About Painting Hardwood Floors
What kind of paint should I use?
High quality, 100% acrylic latex floor paints provide excellent adhesion and durability on wood floors. Oil-based paints are tougher but take much longer to dry. Always choose non-slip paint with some texture to avoid a slippery surface.
Do I need to use primer?
Yes, priming ensures paint adheres well. Oil-based primers lock onto wood best. Alternatively, use a bonding latex primer made specifically for hardwood floors.
Should I use a water-based or oil-based polyurethane?
Water-based polyurethanes are much lower odor and faster drying than oil-based options. They provide good durability for indoor wood floors in residential settings. Oil-based poly gives maximum toughness but takes hours longer to dry and apply safely.
How do I get paint out of cracks?
After painting, use a thin putty knife or 5-in-1 tool to lightly scrape paint out of any cracks or corners you don’t want visible. Wipe the excess away with a damp cloth. Avoid over-scraping to prevent damaging your finish.
Can I paint over stained floors?
Yes, but stains should be screened or sanded down before painting for proper adhesion. Make sure to use oil-based primer when painting over stains or slick surfaces. Test for paint compatibility.
How long does it take to dry between coats?
Typically 2-4 hours between paint coats and 2-3 hours between polyurethane coats. Allow more drying time in cooler, humid environments. Read the manufacturer’s instructions for exact recoat times.
How soon can I walk on freshly painted floors?
Avoid walking on floors until the paint has dried at least 24 hours. Wait 48 hours after applying polyurethane topcoat before resuming normal use of the space. Place cardboard over floors when moving furniture to prevent damage.
