When attaching wood to stucco, follow these steps:
1. Prepare the stucco surface by cleaning it thoroughly and removing any loose material.
2. Mark the desired location for the wood attachment and drill pilot holes into the stucco using a masonry bit.
3. Insert plastic anchors into the pilot holes to provide stability for the screws.
4. Align the wood with the pilot holes and attach it to the stucco using screws that are suitable for outdoor use.
5. Make sure the wood is securely fastened to the stucco before proceeding with any additional steps or installations.
When attaching wood to stuccoed surfaces, the method chosen depends on the function of the wood item. For lightweight, decorative items, construction adhesives are sufficient, but for heavy or load-bearing items, direct fastening to wall studs or heavy-duty wall anchors is required. A masonry drill bit can be used with a standard power drill to bore through stucco to allow screws, lag bolts, or wall anchors to grip the stucco wall. If using adhesive, choose a contact adhesive that grips upon contact and sets quickly, eliminating the need to clamp or hold materials for a long drying period.
Construction Adhesive
Step 1: Surface Preparation
Use a scrub brush and cleaning compound to remove dirt, grease, and grit from the stucco area where you intend to install the wood. Wipe the installation area with a rag and allow it to dry.
Step 2: Applying Adhesive
Clean the rear of the wood with a rag to remove debris and dirt. Determine the adhesive’s set time by reading the instructions for the construction contact adhesive. Apply the adhesive to the wall and onto the rear face of the wood. Press the rear face of the wood against the adhesive-coated stucco and hold it firmly for the duration of the adhesive’s set time.
Wall Anchor
Step 1: Marking the Installation Location
Mark the location of the fastener on the wood’s surface with a tape measure and pencil. Attach a wood bit to the power drill and drill through the wood at the mark. Hold the wood against the stucco surface at the desired installation location. Press a pencil through the wood’s hole and use the pencil to create a fastener mark on the stucco surface.
Step 2: Drilling and Attaching the Fastener
Attach a masonry bit to the power drill and drill through the stucco surface at the fastener mark until the bit penetrates the wall cavity. Remove the screw from the toggle bolt’s toggle. Place the screw through the hole in the wood and thread the toggle onto the screw. Insert the toggle into the hole in the stucco surface and press the wood flush against the stucco surface. Turn the screw clockwise with a screwdriver to draw the toggle against the wall’s interior. Continue to tighten the screw until the screw head rests flush against the wood and securely anchors the wood to the stucco.
Mount to Stud
Step 1: Locating the Studs
Locate studs with a stud finder from the building’s interior or by stretching a tape measure from the exterior wall corner to the wall’s center. Studs are typically spaced 16 inches on center. Mark the studs’ locations on the stucco surface with a pencil, subtracting the thickness of the stucco layer and wall sheathing from your measurements.
Step 2: Drilling and Attaching the Lag Screw
Attach a wood drill bit to the power drill and choose a bit approximately equal in diameter to the smooth portion of the lag screw shank. Drill a hole through the wood. Attach a masonry drill bit to the drill and drill a hole through the stucco at the stud mark, drilling only through the stucco.
Third step
Mount a wood bit onto the drill. Select a bit with a slightly smaller diameter than the smooth shank of the lag screw, as this will allow enough wood for the threads to grip onto. Insert the bit into the hole in the stucco and create a pilot hole in the stud, with a depth equivalent to the length of the screw.
Fourth step
Attach a nut driver to the drill. Align the hole in the wood with the hole in the stucco. Insert the head of the lag screw into the nut driver. Push the tip of the screw through the wood and the hole in the stucco until it reaches the stud. Drive the screw into the stud until the screw head pulls the wood flush against the stucco surface.
