Ever wondered if you can refinish your hardwood floors without doing a full-on sanding job? The answer is: yes, absolutely. But — and this is a big but — if you mess up even one step, it could cost you thousands of dollars in damage.
Let’s walk through how to do it the right way, step by step. And more importantly, let’s make sure you don’t fall into any of the five common mistakes that could totally ruin your floors.
Step 1: Deep Clean Like You Mean It
Before anything else, we need to give those floors a serious deep clean. We're talking about a big ol’ cleaning machine filled with water and a special solution, complete with a fast-spinning brush that scrubs the grime off your floors and sucks the dirty water right back up — all without soaking your hardwood. You can do this by hand or with a buffer, but do not let that water sit too long. Moisture is your floor’s worst enemy.
Mistake #1: Not Knowing What’s Been Used Before
If someone else has cleaned your floors in the past, and you’re not 100% sure what products were used, this could be a huge problem. Products with wax, oil, or other contaminants get deep into the wood — yep, even under the polyurethane. Wood is like a sponge, so these gunk particles soak right into the pores.
Think your floors are clean? They might look clean, but deep down they could still be contaminated. And if you try to apply new polyurethane over those hidden contaminants? It’ll peel, bubble, or turn milky white. Bad news.
Sure, there are ways to test for this stuff, but they’re only about 50% accurate — basically like playing Russian roulette with your floor. If you don’t know what’s been on your floors, don’t risk it.
Step 2: Light Buffing (But Not Too Much)
If your floors have only been cleaned with water or a trusted solution like Bona, congrats — you’re clear to move on. Now comes the light buffing stage. This is where we bring in a floor buffer with something called a screen — it’s like a round mesh pad with some grit to it. This isn’t for sanding down to raw wood; it’s just to lightly scuff the top layer so the new finish has something to grip.
Mistake #2: Old Finish That’s Already Peeling
If your floor’s finish is already losing its grip on the wood underneath, that buffer is going to start flaking it off like a bad sunburn. You might think, “No big deal, I’ll just keep buffing.” Nope. That means the whole top layer of finish has failed, and now you’re officially in full-sand territory. Time to break out the 250-pound belt sander and strip the whole thing down to bare wood. Sorry.
Step 3: Watch Out for Stain Damage
Mistake #3: Buffing Through the Stain
Most floors are stained a different color than the natural wood. If your buffer hits a high spot or thin area in the finish, it can cut straight through the stain and expose raw wood. That’s a big problem.
And no — you can’t just dab a little stain on the spot and call it good. Even if you knew what exact stain was used (which you probably don’t), it would still stand out like a bad car paint touch-up.
Mistake #4: Trying to Spot Sand Damage
We get this question all the time: “Can’t you just lightly sand this little damaged area?” We wish. But sanding deep enough to remove real damage means cutting through both the stain and the finish. And if you do that, you’ve now got raw wood again — which will look totally different once the new clear coat goes down.
Remember: we’re not doing a full refinish here. That buffer is just to scuff the surface, not remove damage. Light buffing ≠ damage repair.
Step 4: Apply the Finish Coat
Assuming your floors made it through the cleaning and buffing stages without any of the problems above — awesome. You’re ready for the new coat of finish.
But hold up...
Mistake #5: Mixing Incompatible Finishes
Do you know what kind of finish is already on your floor? Because you can’t tell just by looking. And if the finish you’re about to apply doesn’t play nice with the old one, you’re back in disaster zone: peeling, weird colors, and probably a regret-filled phone call to a pro.
At Lumberjack Flooring, we only do maintenance coats if:
- We were the ones who last refinished the floors.
- The homeowner swears they’ve only cleaned with water or Bona.
We’re not anti-maintenance coats — they’re super important! You should be doing one every 1–3 years, depending on how wild your household is.
Final Tip: Timing Is Everything
If you’ve got dogs, kids, or you wear shoes in the house, you’re gonna hit that 1-year mark fast. Once you start to see wear spots in the finish — game over. It’s too late for a re-coat. You’re in full sand-and-refinish mode now.
So stay ahead of it. Re-coat before the damage shows up, and you’ll save yourself thousands of dollars (and a major headache).

Wrapping It Up
So yes — refinishing hardwood floors without sanding is totally possible. But only if you:
- Know exactly what’s been used on your floors
- Stick to the right cleaning solutions
- Don’t try to fix damage with spot sanding
- Avoid incompatible finishes
- Time your re-coats wisely
Otherwise, you’ll end up doing the full sand job you were trying to avoid in the first place.
