To scrape a large area, go to Home Depot (or someplace similar) and get a scraper--preferably one you can move with your foot (it will have a tall handle like a garden shovel). Then start scraping the glue off the wood. Then, you'll still need to sand the wood floor and refinish.
To do the whole thing with a sander, plan on using lots of sandpaper, because the adhesive will warm under the sander and turn to goo. Stop and change your sandpaper often. Depending on how much glue you have, you might start with 36 grit, then move to 50, 80, and finally 120 or 150 to finish.How do you get adhesive off of wood flooring after tile is removed?
Go to a home improvement store(Home Depot, Lowe's, Ace etc...) and ask for ';Goo Be Gone';. It is specifically an adhesive remover and has always worked well for me; however, there are more potent and likewise, caustic formulas available. I would ask an expert in one of these stores. Who knows? They could very well have one specifically designed for your situation! Good luck!How do you get adhesive off of wood flooring after tile is removed?
goo gone works on all types of adhesives and will not harm the wood. You may need to let it soak in for between 2 - 5 minutes to easily remove the glue.
