Anchors are needed to secure items such as pictures, fixtures and mirrors to hollow or weak wall surfaces. Stucco presents an interesting challenge because the surface is lightweight and solid, but hollow with variable solid areas. The best type of wall anchor to install in stucco is an all-purpose anchor that spreads wide for hollow areas but only thickens for solid areas.
Mark the location for the wall anchor on the stucco with a pencil. Use two anchors for heavy items if possible. Use a level to mark both locations so they are horizontally equal.
Insert a drill bit the appropriate size for the anchor into the drill. Choose a drill bit based on the information on the anchor packaging.
Drill a hole in the stucco at each location for an anchor. Hold the drill bit at a 90-degree angle to be sure the anchor will be straight in the hole when installed.
Place the base of the anchor in the hole and gently tap the anchor into position with a hammer.
Insert the screw that came with the anchor into the opening of the anchor. Use a drill or hand screwdriver to turn the screw to the desired depth into the anchor in the stucco.
