Engineered hardwood floors are a popular choice for their durability and elegant appearance, but over time, scratches, wear, and dullness can take away their shine.
Instead of replacing them entirely, resurfacing engineered hardwood floors can restore their beauty at a fraction of the cost.
Whether through sanding, refinishing, or a screen-and-recoat process, bringing your floors back to life is possible—if done correctly.
In this guide, I will walk you through the steps to assess and refinish your engineered hardwood floors, helping you decide whether resurfacing is the right solution or if replacement is necessary.
Quick Guide: How to Resurface Engineered Hardwood Floors
- Check Wear Layer Thickness → Must be at least 2 mm for sanding
- Deep Clean Floors → Remove dirt, wax, and debris
- Sand Lightly → Use 120-150 grit sandpaper (orbital sander only)
- Repair Damage → Fill gaps/scratches with wood filler
- Apply New Finish → 2-3 thin coats of polyurethane (water or oil-based)
- Let Cure Fully → Wait 48+ hours before heavy use
Pro Tip: For floors with light wear, try a screen-and-recoat instead of full sanding!

Can You Resurface Engineered Hardwood Floors?
The short answer is yes—but with some important limitations. Unlike solid hardwood, engineered hardwood has a thinner top wear layer, meaning it can’t withstand endless sanding. However, most quality engineered floors can be refinished 1-2 times, depending on their construction.
Key Factors That Determine Refinishability
Wear Layer Thickness
- The top veneer (real wood layer) must be at least 2 mm thick for safe sanding.
- Thinner layers (under 1mm) risk sanding through to the core, ruining the floor.
Number of Previous Refinishes
- Each sanding removes a small amount of the wear layer.
- Check manufacturer guidelines—some engineered floors are not designed for refinishing.
Type of Damage
- Light scratches and surface wear? Perfect for resurfacing.
- Deep gouges, water damage, or delamination? Replacement may be necessary.
Engineered vs. Solid Hardwood Refinishing
| Feature | Engineered Hardwood | Solid Hardwood |
|---|---|---|
| Refinishable? | Yes (1-3 times max) | Yes (multiple times) |
| Sanding Depth | Limited by wear layer | Can be sanded deeply |
| Best Refinish Method | Light sanding or screen & recoat | Full sanding & staining |
When Resurfacing Isn’t an Option
- If the wear layer is too thin (less than 1mm).
- If the floor has severe structural damage (warping, peeling, or deep moisture damage).
Pro Tip: If unsure, consult a flooring professional to assess your floors before attempting DIY refinishing.

Steps to Resurface Engineered Hardwood Floors
Resurfacing engineered hardwood requires careful preparation and the right techniques to avoid damaging the thin wear layer. Follow this step-by-step guide to restore your floors safely.
Step 1: Assess the Floor’s Condition
- Check the wear layer thickness (should be at least 2 mm for sanding).
- Look for deep scratches, dents, or water damage that may require spot repairs.
- Test an inconspicuous area before proceeding with full refinishing.
Step 2: Clean the Floor Thoroughly
- Remove all furniture, rugs, and debris.
- Vacuum and mop with a pH-neutral cleaner to eliminate dust and grime.
- Ensure the floor is completely dry before sanding.
Step 3: Sand the Surface (If Possible)
- Use a fine-grit sandpaper (120-150 grit)—never coarse grit.
- Opt for an orbital sander instead of a drum sander to prevent over-sanding.
- Sand lightly and evenly along the wood grain.
- Vacuum dust between passes.

Step 4: Repair Damaged Areas
- Fill gaps, scratches, or small dents with wood filler matching your floor color.
- Let the filler dry completely, then sand smooth.
Step 5: Apply a New Finish
Choose between water-based polyurethane (faster drying, low odor) or oil-based (more durable but longer dry time).
- Apply with a high-quality brush or roller in thin, even coats.
- Allow proper drying time (usually 24 hours between coats).
- Lightly buff with a 220-grit screen before the final coat for a smooth finish.

Alternative: Screen & Recoat (No Sanding Needed)
If your floors only need a refresh without deep scratches:
- Buff with a floor buffer and abrasive screen (120-150 grit).
- Clean all dust thoroughly.
- Apply 1-2 fresh coats of finish.

Pro Tips
- ✔ Work in small sections for better control.
- ✔ Maintain consistent lighting to spot missed areas.
- ✔ Avoid walking on floors until fully cured (48+ hours).

When Should You Replace Instead of Resurface?
While resurfacing can revive worn floors, some damage is beyond repair. Here’s how to know when replacement is the smarter choice than refinishing or screening.
Signs Your Engineered Hardwood Needs Replacement
The Wear Layer Is Too Thin (Under 1mm)
- Engineered hardwood can only be sanded 1-3 times before the veneer wears through
- If you can see the plywood core in spots, replacement is necessary
Extensive Water or Moisture Damage
- Warping, cupping, or buckling that doesn’t flatten after drying
- Black stains or mold growth (indicates deep moisture penetration)
- Delamination (layers separating) due to prolonged water exposure
Related: Hardwood Floor Repair After Water Damage
Deep Structural Damage
- Large gouges or cracks that penetrate the core
- Loose or missing planks that can’t be securely reattached
- Termite or pest damage compromising floor integrity
Outdated or Poor-Quality Flooring
- Low-grade engineered wood with an ultra-thin veneer (less than 0.5mm)
- Obsolete locking systems that make spot repairs impossible
- Severe fading or discoloration that can’t be fixed with refinishing
Cost Comparison: Refinish vs. Replace
| Factor | Refinishing | Replacement |
|---|---|---|
| Cost | $1.50–$4/sq. ft | $3–$10+/sq. ft |
| Time | 2–4 days | 1–3 weeks |
| Lifespan Added | 5–10 years | 15–25 years |
| Best For | Surface wear | Structural damage |

When to Consult a Professional
- If you’re unsure about the wear layer thickness
- If there’s subfloor moisture issues (may require new underlayment)
- If you want to change flooring type (e.g., switch to solid hardwood)
Pro Tip: For localized damage, consider partial replacement if you have extra planks from the original installation.

FAQs
Got questions about refinishing your engineered hardwood? Here are answers to the most common concerns:
Can You Sand Engineered Hardwood Floors More Than Once?
✅ Yes, but only 1-3 times max – depending on the wear layer thickness (minimum 2mm required per sanding).
Always check manufacturer guidelines first.
What’s the Difference Between Refinishing and Resurfacing?
- Refinishing = Sanding down to bare wood + applying new stain/finish
- Resurfacing = May include screening/light sanding + recoating (less invasive)
How Much Does It Cost to Resurface Engineered Hardwood?
| Method | Average Cost (per sq. ft) |
|---|---|
| Full sand & refinish | $3–$5 |
| Screen & recoat | $1–$3 |
| DIY refinishing | $0.50–$2 (materials only) |

Can You Change the Color When Resurfacing?
⚠️ Only with full refinishing (sanding to bare wood). Screen & recoat only refreshes the existing color.
How Long Does Refinished Engineered Hardwood Last?
- Sanded & refinished: 7–15 years with proper care
- Screen & recoat: 3–5 years before needing another refresh
What’s the Biggest Mistake to Avoid?
🚫 Using a drum sander or coarse grit – This can sand through the thin veneer in seconds.
Always use orbital sanders and 120+ grit.
7. Can You Spot-Repair Engineered Hardwood?
- ✔ Yes for minor damage – Use wood filler and touch-up pens.
- ❌ No for large areas – Replacement planks blend better.
How Do I Know If My Floors Are Beyond Resurfacing?
Replace if you see:
- Visible plywood core (sanded through veneer)
- Warping or mold from water damage
- Loose/lifting planks
