Dryvit is a relatively new product designed as an alternative to standard household stucco. Dryvit comes in 1- and 5-gallon premixed buckets that spread over a foam insulation and mesh backing. Because of the way it's installed, this product is ideal as a brick coverup. This system has a better economic value than the traditional stucco because of the strength and insulation value of the materials used. Once complete, Dryvit walls texture and paint just like typical home stucco walls. Everything needed for this project is available at most larger home improvement centers or hardware stores.
Measure the brick surface with a tape measure to get the total square footage needed to cover it completely. Add 10 percent to the total to allow for bad measurement or waste.
Cut the gypsum paneling with a circular saw to the dimensions required to cover the face of the brick. Test-fit the newly cut panel and have an assistant hold it in place while you drill 3/16-inch pilot holes through the board along the perimeter at approximately every 4 inches. Stop the drill as soon as you hear it hit the brick for all holes, and then remove the panel and set it aside.
Drill pilot holes into the brick using a 1/4-inch masonry bit. Drill slowly and keep the bit level to avoid cracking or chipping the masonry. Complete all holes and insert 1-inch masonry anchors into each of the holes.
Replace the gypsum panel over the brick and align the holes. Insert 1 1/2-inch screws into the wood and tighten them through to the masonry anchor. Complete the process for all holes to secure the panel to the brick.
Apply construction adhesive to the face of the panel with a trowel and cover it completely. Place and smooth sheets of polystyrene insulation from the top of the panel to the bottom into the adhesive. Cut pieces to fit using a utility knife. Allow the insulation, glue and panel to bond together for an hour before proceeding.
Spread a second layer of the adhesive over the insulation and fit sheets of fiberglass mesh into it. Let this layer dry for another hour prior to trimming the excess fiberglass mesh to fit, using the utility knife.
Trowel on the Dryvit material approximately 1/8-inch thick. Apply it as you would drywall compound or stucco, and smooth it or texture as you like. Let the layer cure for approximately two hours, and then place another layer to reach the desired thickness. Allow the wall to completely cure overnight.
Use paintable silicone caulk to seal any joints between other construction materials and the new Dryvit section. Paint the new wall covering with any color latex house paint.
