A drywall hole that has been filled with spackle will not support a screw. Spackle, also known as joint compound or “drywall mud,” is not as durable as true drywall. Joint compound will shrink and pulverize easily when a screw is driven into it.

How long should spackle dry before drilling?

Let the spackle dry for 4-5 hours. The amount of time it will take your spackle to dry depends on the size of the hole, how much spackle you applied, and the brand of spackle you used. Once your spackle is dry, sand it down before applying your second layer.

Is spackle stronger than drywall?

Spackle is made for small repair jobs on drywall. It’s thicker than joint compound and harder to spread. Because it has a binding agent mixed in with the gypsum powder, it is more elastic and less likely to crack or shrink when dried. Spackle is a little more expensive than joint compound.
