Slate Patch for Patching Chips and Holes
This is what we use to fill chips and holes in slate. This product gets very hard. Probably harder than the slate itself. It's meant to be a permenant fill. The best quality is that it does not shrink while drying. You fill once, let it dry, then lightly sand with a sanding block.
This is not a good candiate for filling seams. Use the bees wax with resin instead.
50 grams per package which can fill a couple of medium sized holes.
