Be sure the hole are free of contamination, oils, and dust. The affected area is best to be a rough texture to allow for bonding. Patch the affected area with a stainable polymer modified patching material or you can use gray portland cement with some sand aggregate. If using the polymer patch option, be sure to apply TWO coats (one filler and one finish). If you decide to use the portland mix, scrub some re-emulsifiable bonding agent into the hole before you fill in the patch, allowing it to dry ONCE.Be sure the patch is completely dry and cured before you stain otherwise the patch may turn out darker than the rest of the floor.
