Application of Filler with Putty Knife Gradually

Gradually apply the filler as much as necessary. Now use a clean putty knife to smooth out the filled area nicely. This will provide an even result that will hardly look like you’ve repaired it.
Let the Filler Dry Completely
Depending on what wood filler you are using, the time necessary to dry it will vary. You should refer to the manufacturer’s recommendations for this. There should be some mentioning of the appropriate time necessary for drying. However, based on the depth of application, this drying period can be somewhere between 15 minutes to 8 hours.
Final Sanding to Match the Surrounding Wood Height

Here you should know the right way on how to use stainable wood filler as well as applying stain following to that. However, staining can be a bit tricky for the first-timers. One good method is using a random piece of scrap wood to dab filler onto it. Let the filler dry and then you can stain to see if things match together or not.
Depending on outcome, you can decide whether to thin out the stain or go for another shade. And if odds are in your favor, then the stain will match close enough for a cheap, easy and fast fix next.
Critical Points on Filling gaps in Hardwood Floors That You Must Know!
There are a few points that you should know about hardwood floors and before trying any filler things to it. First of all, be aware of the fact that wood is supposed to expand and contract depending on seasonal humidity changes. Are you seeing the gaps during the dry winter months? But also, there are not many noticeable gaps during humid seasons?
If you are answering both questions yes, then it’s best to leave it alone. This is because when you decide to fill the gaps on its widest condition, with expansion this will bring further problems later. In worse cases, with no room left for expansion, it can buckle as well.
If the case is about filling gaps in old wood floors, then know that those developed gaps can be more or less constant. While there’s still a chance of becoming narrower or wider because of humidity changes here.
The best way to be sure here is to check flooring during humid season. This is when the wood will be most swollen. If you believe that these gaps are enough big to hold a standing nickel inside, then there’s a problem and it needs some correction. Also, if you believe that the gaps are existing for year-round, things are probably safe to try filling.
And that was basically everything about how to use wood filler on hardwood floors. Here’s a quick note we want you to know. Wood fillers are no permanent fix. With the expansion and contraction, its effectivity will get compromised.
And the only savior to hold it is maintaining proper humidity. Also, fillers won’t be the best solution for huge gaps. So be sure you are expectations are not beyond what a wood filler can provide. Also, that does not make the wood filler a less helpful solution by any means. It’s just that you need to be in touch with the hardwood’s maintenance frequently as well.
