How to Attach Wood to the Stucco Wall

Depending on the function of the wood item, there are corresponding methods builders use in attaching wood to a stucco wall or surface. 

Construction Adhesive

  1. Clean the stucco surface area using a scrub brush and cleaning solution.  Make sure to remove the dirt, grit, and grease especially to the spot where you intend to install the wood. Using a dry rag, wipe it out and allow it to dry.
  2. Carefully read the instruction for the construction contact adhesive to identify the set time for adhesive before applying it.
  3. Squeeze and apply adhesive into the wall and on the rear side of the wood. Put and press the rear face of the wood against the stucco that is coated with adhesive. Firmly press and hold the wood against the stucco as indicated set time for the adhesive. 

Mount to Stud

  1. Find studs by stretching a tape measure from the exterior wall corner to the center of the wall or search using stud finder from the interior of the building. Usually, studs are spaced 16 inches on center. From your measurements, minus the width of the stucco layer and wall sheathing. Then, using a pencil mark the location of the stud fo reference. 
  2. Fasten the wood drill bit to the power drill. Select a bit that is almost close or equal in diameter to the smooth portion of the lag screw shank. Take note that the smooth portion excludes threads. Cut a hole through the wood and attach a masonry drill bit to the drill. On the stucco stud mark, drill a hole. 
  3. Fasten a wood bit to the drill. Choose a quite smaller in diameter than the lag screw’s smooth shank so that there’s sufficient wood for threads to grab. Through stucco’s hole, feed the bit and start drilling a starter hole into the stud. The depth of the starter hole must be approximately equal to the length of the screw.
  4. Fasten the nut driver to the drill. Place the hole in the wood and the hole in the stucco in alignment with each other. In the nut driver, mount the head of the screw. Push the screw tip through the wood and the stucco’s hole until the tip reaches the stud. Drive the screw into the stud and keep working until the crew’s head pulls the wood flush against the stucco surface.

Wall Anchor

  1. Mark using a tape measure and pencil the spot where the fastener of the wood’s surface is located. Fasten the wood a little to the power drill then drill through the wood exactly at the mark. Place the wood against the surface of stucco at the preferred installation spot. 
  2. Fasten the masonry bit to the power drill. At the fastener mark, drill through the stucco surface until the bit reaches the wall cavity. For the toggle bolt’s toggle, unfasten the screw.  Right through the wood’s hole, use the pencil to draw a fastener mark on the stucco surface. 
  3. On the surface of the stucco, feed and pish the toggle. The wood flush must be pressed against the stucco surface. In order to draw the toggle against the interior of the wall, turn the screw clockwise using a screwdriver. Just continue to tighten the screw until the screw head flush lies against the wood and strongly attach the wood to the stucco.
