Screening and recoating offers an alternative for hardwood floors that are showing their age but haven't suffered significant damage. This process removes the old finish and a very thin layer of wood, allowing a fresh coat of polyurethane to bring back the shine and protect your floors.
In this guide, I will walk you through everything you need to know about screening and recoating hardwood floors, from assessing your floor's condition to achieving a flawless finish.
Quick Steps to Screen and Recoat Hardwood Floors:
- Prep: Clear the room, protect trim, and ventilate.
- Clean: Thoroughly clean the floors and let them dry.
- Screen: Use a buffer with coarse, then fine grit screens, following the wood grain.
- Vacuum & Tack: Remove all dust with a vacuum and tack cloth.
- Apply Finish: Apply thin, even coats of polyurethane, letting each dry completely.
- Cure: Allow the final coat to cure fully before resuming normal use.

When to Screen and Recoat
screening and recoating is the sweet spot between simple cleaning and a full-blown sanding and refinishing job. So, how can you tell if your hardwood floors are ready for this type of rejuvenation? Look for these telltale signs:
- Surface Scratches and Scuffs: Everyday wear and tear can leave a network of fine scratches on the surface of your floor's finish. Screening effectively removes these superficial blemishes.
- Dull or Worn Finish: If your floors have lost their luster and shine, even after cleaning, it's a good indicator that the finish is wearing thin and needs to be refreshed.
- Discolored or Patchy Finish: Areas of discoloration or uneven sheen can also point to a worn finish that would benefit from screening and recoating.
However, screening isn't a solution for every hardwood floor issue. Full sanding and refinishing will be necessary If you have:
- deep scratches that penetrate the wood itself
- significant gouges
- or extensive water damage
Similarly, if your existing finish is peeling or flaking off, screening won't adhere properly.
Generally, a hardwood floor finish lasts anywhere from 3 to 5 years with regular maintenance.
Materials and Tools Needed
Before you begin the screening and recoating process, gather all the necessary materials and tools. Here's a comprehensive list:
- Floor Buffer: For screening your floors—you can rent one from most home improvement stores. Make sure it comes with the appropriate sanding screens.
- Sanding Screens: These are attached to the buffer and come in different grits. Start with a coarser grit (around 100) and progress to a finer grit (150-180) for a smooth finish.
- Hardwood Floor Cleaner: Choose a cleaner specifically designed for hardwood floors to remove dirt, grease, and grime before screening.
- Vacuum with Soft Brush Attachment: Essential for removing dust and debris after screening.
- Tack Cloth: This sticky cloth will pick up any remaining fine dust particles before applying the finish.
- Applicator: You can use a lambswool applicator, a T-bar applicator, or a high-quality brush designed for polyurethane.
- Polyurethane Finish: Select a high-quality polyurethane finish specifically designed for hardwood floors. Consider the sheen level (gloss, semi-gloss, satin) you desire.
- Paint Tray or Bucket: For holding the polyurethane finish.
- Painter's Tape: For protecting baseboards and trim.
- Drop Cloths or Plastic Sheeting: To protect your furniture and other areas from dust and spills.
Safety Gear
- Safety Glasses and Dust Mask: Protect your eyes and lungs from dust and fumes.
- Gloves: Protect your hands from the chemicals in the finish.
- Knee Pads: For added comfort during the screening process.
Investing in quality materials and using the right tools and products will ensure a beautiful, long-lasting finish for your hardwood floors.
Don't hesitate to ask for recommendations at your local home improvement store if you're unsure about which products to choose.
Step-by-Step Guide to Screening and Recoating
Now that you have all your materials and tools assembled, let’s dive into the step-by-step process of screening and recoating your hardwood floors. Follow these instructions carefully for optimal results:
Step 1: Preparing the Room:
- Clear the Room: Remove all furniture, rugs, and other items from the room.
- Protect Baseboards and Trim: Use painter's tape to mask off baseboards, door frames, and any other trim you want to protect from the buffer and finish.
- Ventilation: Ensure proper ventilation by opening windows and doors. Good airflow is crucial for dissipating dust and fumes.
Step 2: Cleaning the Floors:
- Thorough Cleaning: Use a hardwood floor cleaner and a mop or microfiber cloth to thoroughly clean the floors. Remove all dirt, dust, grease, and grime.
- Any residue left on the floor can interfere with the adhesion of the new finish.
- Dry Completely: Allow the floors to dry completely before proceeding to the next step.
Step 3: Screening the Floors:
- Attach Sanding Screen: Attach the coarser grit sanding screen (around 100 grit) to the buffer.
- Start Screening: Begin screening the floor in small sections, moving the buffer back and forth in the direction of the wood grain.
- Overlap each pass slightly to ensure even coverage.
- Switch to Finer Grit: Once you've screened the entire floor with the coarser grit, switch to a finer grit sanding screen (150-180 grit) and repeat the process.
- This will smooth out any scratches left by the coarser grit and create a smooth surface for the finish.
Step 4: Cleaning After Screening:
- Vacuum Thoroughly: Use a vacuum with a soft brush attachment to remove all the sanding dust from the floors. Pay close attention to corners and edges.
- Tack Cloth: Go over the entire floor with a tack cloth to pick up any remaining fine dust particles. This is crucial for achieving a smooth, flawless finish.
Step 5: Applying the Finish:
- Prepare the Finish: Stir the polyurethane finish thoroughly according to the manufacturer's instructions. Do not shake the can, as this can create bubbles.
- Apply the First Coat: Using your chosen applicator (lambswool, T-bar, or brush), apply a thin, even coat of finish to the floor, working in small sections.
- Follow the direction of the wood grain.
- Drying Time: Allow the first coat to dry completely according to the manufacturer's instructions.
- Apply Additional Coats: Apply at least two coats of finish, allowing each coat to dry completely before applying the next.
- Lightly sand with fine-grit sandpaper (220 grit) between coats to ensure proper adhesion.
- Final Coat: Apply the final coat of finish, taking extra care to avoid creating bubbles or streaks.

Step 6: Final Curing:
- Curing Time: Allow the final coat of finish to cure completely according to the manufacturer's instructions. This typically takes several days.
- Avoid Heavy Traffic: Avoid walking on the newly finished floors as much as possible during the curing period.
- Don’t Place Furniture and Rugs: Refrain from placing furniture or rugs on the floor until the finish is fully cured.
Remember to consult the manufacturer's instructions for your specific products for the best results.
Tips for a Successful Recoating
Here are some essential tips to ensure a successful outcome:
- Ventilation: Open windows and doors to allow fresh air to circulate and carry away dust and fumes.
- Temperature and Humidity: Ideal conditions for applying polyurethane are between 60-80°F with moderate humidity.
- Avoid recoating during extremely hot, cold, or humid conditions, as this can affect the drying and curing process.
- Choose the Right Finish: Select a finish that suits your lifestyle and desired aesthetic.
- Gloss finishes offer maximum shine but show scratches more easily.
- Satin finishes provide a softer sheen and are more forgiving.
- Consider the level of traffic in the area when making your choice.
- Thin Coats are Best: Applying thin, even coats is crucial for preventing bubbles, streaks, and uneven drying.
- Don't Rush the Drying Process: Allow each coat of finish to dry completely according to the manufacturer's instructions before applying the next.
A little extra attention to detail will make a significant difference in the final result.
FAQs
How long does the entire screening and recoating process take?
The process typically takes 1-2 days, depending on the size of the room and the number of coats of finish applied. Keep in mind that the finish needs adequate drying time between coats and a longer curing period before heavy traffic is allowed.
How long does a recoated finish last?
With proper care and maintenance, a recoated hardwood floor finish can last for 3-5 years before needing to be refreshed.
What are the different types of polyurethane finishes available?
The most common types are oil-based and water-based polyurethane:
- Water-based finishes are generally low-odor and dry faster.
- Oil-based finishes offer greater durability but have a stronger odor and longer drying time.
Can I screen and recoat engineered hardwood floors?
Yes, in most cases, engineered hardwood floors can be screened and recoated. However, the wear layer of engineered wood is thinner than solid hardwood, so it's essential to proceed with caution and consult a professional if you're unsure.
Over-screening can damage the veneer layer.
