How to Correct a Slate Floor Chip

Updated February 21, 2017

Slate flooring is a wise design choice for homes as it offers manageability and versatility. Slate consists of minute pieces of silt and clay that have bonded at high temperatures and pressure, making it resistant to stains. It comes in a wide range of shades and hues, from charcoal to green to sienna, so you're likely to find a colour that complements your decor. However, while slate is strong, it's not indestructible. If you drop something heavy on a slate floor, it could chip. Fortunately, it can be repaired.

Brush away any dirt or loose bits of slate from the area with a feather duster. Scoop out a tiny amount of epoxy filler on a putty knife.

Pat the epoxy filler over the chipped area of the slate, smoothing it over the chip. If you've matched the epoxy filler perfectly with the slate floor, the patch should be nearly invisible.

Allow the patch to dry for 24 to 48 hours before walking on it. When the patch is fully dry, examine it. Some epoxy fillers dry lighter than the stone around them. If that's the case, purchase a heavy-duty paint for stone and test it on a small area of the slate with a 1/2-inch nylon brush. Allow it to dry overnight.

Paint over the dried epoxy with a brush and the speciality stone paint if the paint dried to an appropriate shade.
