Q&A: What Are These Strange Raised Areas in this Wood Floor?

1 L 1023 Wfb On23 Qn A Raised Dents

What are the raised areas? This is a sand and refinish; the raised areas are all the same, with some bridging across a board seam. The floor was sanded flat, water-popped and stained. There are three or four spots in this three-point section and none anywhere else. They are not in the finish coat—they are wood. â€” Brent Kelosky, Sport Floors Inc. (Koppel, Pa.)

Patrick Russell at All American Floor Sanding and Installation in Ocala, Fla., answers:

Those were existing dents that were in the floor prior to sanding. They were sanded flat, and when the floor was water-popped, the moisture made the compressed wood regain its normal shape, rising above the rest of the wood floor. This is similar to the technique of getting dents out of a wood floor with moisture and an iron—just that in this case, the waterborne finish provides the moisture, and the dents decompress without the added heat.
