Just because your home has a brick wall doesn't mean that you can't accessorize it. The building material might be more intimidating to work with than the standard drywall or wood when it comes to mounting items to walls, but you can mount many things to brick using heavy duty construction adhesive. You can mount house numbers, wrought iron wall art and other home accessories to brick without having to drill into it. Select the location of the object you are mounting carefully, since you won't be able to adjust it once the adhesive bonds.
Hold the object that you want to mount on the brick surface in place. Mark the corners of the object with a pencil so that you have registration marks to apply the adhesive and mount the object.
Brush the area where the object is to be mounted with a wire brush to remove any loose debris on the surface of the brick. Sand the surface with a medium/coarse-grit sanding block to roughen the surface of the brick so that the adhesive bonds effectively.
Insert the tip of the heavy duty construction adhesive tube into the built-in cutter on the caulk gun and cut the tip off at a 45-degree angle. Puncture the seal inside the tip with the seal punch on the caulk gun. Pivot the heavy duty construction adhesive tube, tip first into the caulk gun.
Apply a bead of adhesive around the inside area of the brick surface where you plan to mount the object to the brick. Apply a bead of adhesive around the inside area of the back side of the object.
Align the object over the pencil marks on the brick surface and press it into place within 10 minutes of applying the adhesive. Clamp the object to the brick on each side with squeeze clamps.
Wipe off any adhesive that may squeeze out around the edges of the object with a cloth rag dampened with warm soapy water. Allow the adhesive to dry for 24 hours and remove the squeeze clamps.
