Problem: Many of our customers will decide to change the color of their stucco in order to update the appearance of their home and improve the drive-up appeal, even if the stucco has no problems.
Solution: Stucco usually comes pre-colored and does not need to be painted. If applied well stucco can last decades without needing significant repair or maintenance. Sometimes the want to paint stucco is just a matter of color choice. For previously unpainted stucco surfaces ServiceFirst Painting recommends using the ROMABIO BioGrip Primer and Masonry Paint. This paint is made of potassium silicate and maintains the natural permeability and breathe-ability of the stucco. This is the best solution to changing stucco color and maintaining the integrity of the original stucco.
Stucco is a beautiful choice for your home’s exterior. A combination of sand, lime, Portland cement and water, stucco provides a durable weather-resistant substrate to protect your investment from the elements. However, with the Texas heat, severe weather and dramatic changes in temperatures your homes stucco exterior can begin to fade, crack, fracture and chip. Additionally, it can become stained and discolored from atmospheric soil, mold and mildew.
ServiceFirst Painting has the expertise to revive your homes beautiful appearance and curb appeal. Painting and maintaining a stucco home with its rough and textured surfaces can be a daunting task but you can count on ServiceFirst Painting to complete the project right the first time, on time. Outlined below are a few challenges faced when painting a stucco home and the expert advice from ServiceFirst Painting.
Problem: Temperature change causes the stucco to expand and contract allowing moisture behind the stucco. This moisture penetration results in hairline cracks to the substrate, which in turn causes further damage to the stucco and makes the paint flake and peel.
Solution: Before priming and painting the stucco our team will repair minor damage and cracks using Sherwin-Williams ConSeal Elastomeric Sealant or Textured Elastomeric Patches. The elasticity properties of these products helps reduce the chance of these cracks reappearing.
Problem: Prolonged moisture can cause mold or mildew to stain and discolor the stucco, as well as prevent the new paint from bonding to the surface resulting in flaking or peeling.
Solution: In order to eliminate the mold and mildew a “mildew bath” is required consisting of a mixture of bleach and water applied to the affected areas. Allow the solution to work for 15 minutes and agitate with a brush if necessary.
Problem: A white staining often occurs on masonry surfaces like stucco as a result of salt deposits, or “efflorescence”. Efflorescence is caused when water interacts with the stucco and the sun’s heat draws the salt deposits to the surface of the stucco as the evaporation process occurs during the day. These stains are not easily removed and will not disappear on their own.
Solution: On occasion these white stains can be removed with a stiff brush. If this process does not work then an appropriate acid may be required to remove the stain and should be left to the professionals at ServiceFirst Painting. Sherwin-Williams SherLastic Elastomeric Coatings are formulated to resist efflorescence.
Problem: Ultraviolet radiation from the sun causes the binders and pigments in the paint to break down resulting in chalking and a loss of color. Wipe your hand across the stucco surface of your home. If a pale colored residue comes off on your hand then “chalking” has taken place and it is time to repaint the exterior of the home.
Solution: When painting stucco, particularly when chalking and significant color fade has occurred, the following process is recommended in order to achieve superior results. ServiceFirst Painting will pressure wash the surface to remove the chalking and compromised paint, atmospheric soil and other contaminants. Once the surface is clean and dry it may be necessary to apply a masonry primer. Sherwin-Williams Loxon coatings can help solve many of the challenges found with stucco including bridging hairline cracks, and resisting high pH, alkalinity, efflorescence, chalking, fading and mildew for beautiful color and sheen that lasts. Now it’s time to begin painting!
