Straight answers
How big a hole can it fill?
Holes up to about 1 inch. Mesh and the injection plate hold the material in while it expands.
When can I hang something?
In about 1 hour for a 1 inch hole, or 4 hours for a ½ inch hole. It reaches full strength at 7 days.
Can I paint over it?
Yes. Once it has cured, sand it flush, then paint, texture or drill it.
