Lou asked 6 years ago

Used Siko spackling in nail holes on wood planter box, then primed w/100% acrylic primer. It’s all lifting off surface where spackling was used.

1. Should I have primed wood first?
2. Could it be lifting because spackle didn’t cure?
3. How long should one usually let spackle cure?
