Stucco is simply a mixture of various concrete that is applied in several layers. This application results in stucco’s strong bond to the wall. When you apply stucco to a solid wall, or a steel or wooden framework, you may need some experience under your belt. However, if you’re a newbie, such a project is easily done with the assistance of a knowledgeable handyman.

Before actually starting the process, it is important to consult with the weather forecast for the next coming days. You would not want to do the job if the temperature is predicted to go below 4 degrees Celsius or above 32 degrees Celsius within the week. This is because stucco should be applied during an overcast day, with temperatures ranging from 10 to 16 degrees Celsius, and with low winds.

 

  1. When the weather is ideal as checked, you may now start by putting up sheathing materials. Any rigid material can be bonded to your support studs, such as oriented strand board or plywood. You may stucco over these materials. When you stucco over an open frame, your wall will not be so even and secure.
  2. Then, cover the plywood using two layers of building paper. You may install the weep screeds and the casing bead after this. Then, a metal lath should be attached, after which control joints should be installed. Control joints are especially important when dissimilar walls meet.
  3. From one part cement material and 2 and a quarter parts plaster sand, mix the scratch coat. Then mix in potable water, just enough so that the stucco can be troweled. Using a square trowel, apply the scratch coat into the lath, pushing firmly as you do so. Allow the scratch coat to cure for at least 48 hours, while preventing the stucco from drying out. You can do this by misting the stucco twice a day and protecting the stucco wall with a windscreen.
  4. Apply the brown coat after mixig, and then wet cure for another seven days, at the least. Finally, you can cover this with the finish coat. You should wet the surface if the finish is colored to prevent mottling.
