Repair and Paint Stucco

logo

Stucco is a durable material that can be left as is; if moisture in the air can pass freely through its porous surface, it will not become trapped inside the building. Stucco can be cleaned as needed with an approved cleaning solution and low water pressure. If cracks occur in the surface, they should be repaired.  There are some great tips for stucco repair from my old military buddy’s painting business in Chandler, Arizona.  His website is: http://BGBpainting.com

 

Stucco comes in shades of white, neutrals and earth tones. If you want to change the color of your stucco home, it can coated with a cement and water mixture that has been tinted with color pigment of your choosing.

Paint can be tricky to stick to previously painted stucco. Sometimes you may have to give the surface something to grip or hold on to.  If so, you can scratch the stucco with a wire brush. If the previous paint is in really bad shape, you have two options:  (1) Pressure wash the house, which you can DIY.  If that doesn’t work, you can sandblast the surface. It is recommended that you use a professional if you need to sandblast.

There are several considerations when choosing masonry paint.

  • Ability to breath allowing internal moisture to escape and still be resistant to external sources of water.
  • Flexible – Move with the house without splitting at any temperature.
  • Bridge small cracks. Removing these unattractive non-structural cracks.
  • Resist dirt pick-up and mildew growth.
  • Be resistant to chipping, chalking and peeling for maximum longevity.

 

No matter which type of paint is used at least the first coat should be back-rolled to properly fill the pinholes and tight cracks. This method will require two people, one spraying and one rolling. The same considerations when brushing and rolling need to be followed.

Apply the paint as a thick continuous film, immediately roll behind the sprayer. On a hot day you will have to move quickly. To make this a more enjoyable experience, work in the shade as much as possible and follow behind the sun.

Begin spraying at the top and work your way down, working the wall in sections. In order to cover the surface efficiently spray using a horizontal, side to side, movement and back roll using a vertical, up and down, movement.

The objective when painting stucco is to provide a continuous film of paint and a pinhole free surface. Do not skimp on the quality of primer or paint and the amount used. Use the best method specific to you and your own situation.
