Sanding Old Hardwood Floors

Over time, a hardwood floor’s finish will become thinner over the high traffic areas first. But getting your floors completely clean and even looking will involve removing the rest of the finish. A floor sander is usually required for this type of work. You can rent one of these at your local home improvement center.

However, if you’re not used to working with a floor sander, this fact could evidence itself later on. Not only will a professional sanding save a lot of frustration, but it could also save your floor.

There Are Limitations When It Comes To Sanding Old Hardwood Floors

A hardwood floor can only be sanded so many times before replacement should be considered. If your hardwood floors have already been sanded too many times to survive another sanding, a professional will be able to determine this.

What if the stains are foul-smelling?

How To Remove Foul-Smelling Stains From Old Hardwood Floors

For foul-smelling stains, this means that whatever caused the stain is still present. Depending on how long this has been the case, the subfloor might be affected as well. Removal of the affected floorboards to address the floor beneath should be considered. Start with the floorboard located at the center of the stain.

With the affected floorboard removed, look at the underside of it. If the stain has saturated it, you’re better off replacing it than trying to get the stain removed.

If it looks like the adjacent floorboards will be in the same shape, remove and check these as well. Continue to work your way outward until you come across floorboards that aren’t stained through and through. That is to say that looking at it from the exposed edge, a significant portion of the floorboard remains unstained. These lesser stained floorboards don’t need to be replaced and therefore, don’t need to be removed.

What To Do If Your Old Subfloors Are Foul-Smelling

If the subfloor has traces of stain on it, try using an enzymatic cleaner to consume what’s left of the problem. Apply it liberally to the affected area of the subfloor only.

Also, be sure not to drench the subfloor or allow any of the solution to puddle. Soak up any excess with a clean, dry rag, The solution will continue to do its job even after you’ve done this.

Return to the area in a few hours. If the floor is dry and the smell is gone, spray the solution onto the subfloor again. The moisture will reactivate any lingering odor. Soak up any puddling and allow the enzymes to resume doing their job. Repeat this process until you’re satisfied that the subfloor is completely odor-free.

You can also try soaking stains with hydrogen peroxide. Saturate a clean terry cloth rag with it and lay it over the stain. Cover the rag with plastic food wrap. Keep the wrap in place by setting something heavy on top of it. A water jug will work.

Leave the saturated rags in place for a couple of hours before checking the stain. You can leave the rags in place for up to eight hours.

If a large area of the subfloor is significantly blackened and foul-smelling, it will probably need to be removed and replaced. A professional flooring installation expert or general contractor would be the one to determine this. Because a subfloor must be completely supportive and stable, it’s best to let a professional do this type of work. A professional will also be able to tell you if and to what extent the floor joists may be affected.

Once you’re sure your subfloors are no longer a concern, replacement floorboards can be installed. If you don’t have any of these left from the time your hardwood floor was first installed, there’s another option; Remove an unaffected floorboard and take it to your local home improvement center or flooring specialty store to match it.
