Removing paint from a hardwood floor is a process that takes differing amounts of time depending on the amount and type of paint that has been spilled. Items needed are a putty knife, hair dryer, rag and mineral spirits.
Scrape with putty knife
Using a putty knife, gently scrape around the paint stain on the floor. Some types of paints, especially those that haven't been cured yet, can be removed with a simple scraping. However, if the paint stain isn't removed with the putty knife, the paint may need to be warmed up.
Warm the paint
Turn on the hair dryer and apply it directly to the paint stains. After the paint has had some time to warm up, try using the putty knife again. Depending on the type of paint, this may be enough to get the paint loose enough to remove it. If not, then solvent may be needed.
Apply mineral spirits
Lightly dampen a rag with the mineral spirits. Then, delicately dab at the stain. The use of this solvent should be enough to get most paints off of hardwood floors and out of crevices. However, solvents can be damaging to floors and should be used as infrequently as possible.
