I’ve bought some, I’m a little nervous to use them I am worried about overspray bouncing back up and hitting the wet side underneath. Do you use 3 inch screws? Do you go in 2 inches on each side? Drywall screws? How do you keep them from spinning when you’re doing the hinges?
You can go in 2 inches from the side. Seems to be the best distance. You can use the 2 5/8" screw that comes with them. Sometimes, it's best to pre drill to avoid any issues. You have to flip the stakrack around to use that locking feature for your door hinges.
