Stucco FAQs, answered by experts

Several clues suggest that your stucco is damaged or has underlying issues. Visual clues include discoloration, cracks, indentations, broken caulking, or visible mold. If you touch your stucco and feel any soft spots, that could also indicate a problem. If you notice any of these concerns, call in an inspector who can confirm your suspicions and help provide solutions.

Stucco applied over brick can last 30 to 50 years or more when correctly applied and properly maintained. Stucco’s lifespan can be shortened by improper application, incorrectly mixed material, lack of preparation before application, and lack of maintenance. To get the most life out of your stucco siding, keep up with maintenance and repair any damage as soon as you discover it. 

Masonry screws are the best option to be used on stucco. They’re thicker and made to penetrate harder surfaces like concrete and cinder blocks. Fluted masonry screws work the best because they create a stronger grasp thanks to the lines on their shafts. If you’re working on exterior stucco, use galvanized screws to prevent corrosion.

Tools include trowels, floats, and patching compounds. Professionals use these for precise and durable repairs.

Stucco will dry in two to three days, but you should wait one to two months to allow it to cure fully before you paint it. The curing process is slow, but leaving the material exposed to air and natural moisture will help it reach its maximum strength. If you live in a hot, arid climate, wait a month before painting. Wait two months before painting if you live in a more moderate or wet climate.
