Stucco Repairs Got You Stuck? 8 Tips For Simple DIY Project Success

Gregory Walker

Stucco is a plaster-like substance applied over walls for appearance and durability. It is occasionally used on interior walls but is mostly frequently used on the exterior of homes and buildings. The classic forms of stucco are very sturdy building materials and have been used for hundreds of years. However, stucco does need maintenance and repairs from time to time and doing it properly is critical to preventing further damage. Simple DIY repairs and maintenance can be successfully undertaken by a homeowner, but larger scale repairs should be performed by an experienced contractor.

What is Stucco Made of?

Traditional stucco is made from lime (calcified limestone), sand, and water. More recently, stucco is being made from portland cement, sand, and water. Traditional stucco was very durable, easy to work with, and easy to paint. The materials also reflected heat and kept homes cooler making it particularly desirable for hot regions. Newer forms of stucco are less durable and can crack and deteriorate more easily. Preventative maintenance and repairs must be done by companies like Advanced Wall Systems Inc in a timely way to avoid more serious and expensive problems.

Tips for Simple DIY Stucco Repair Success

To make simple repair patches for modern stucco, mix ½ bag of portland cement, 6 shovel fulls of moist mason or brick sand, 1 shovel full of hydrated lime, and 1/2 c. of an acrylic bonding agent. If a smaller quantity is needed, be sure to keep ingredients in the proper ratio when reducing.

Combine all the dry elements in a wheelbarrow and blend them well. Add the liquid acrylic bonding agent, and then add water a small amount at a time. Continue stirring until the repair mixture takes on the texture of a frosting.

Some tips for successful mixing and simple repairs are:

  • Don't add more water than necessary to the cement mixture. Excess liquid will make the repair materials too loose to work well.
  • Don't mix more stucco than can't be used in 30 to 90 minutes. After that time, the stucco will begin to harden and be unusable.
  • Moderate temperatures are best for stucco repair. Temperatures at night should be at least 40°F. Bright sunlight, low humidity, heat and wind can dry out stucco quickly. Work quickly and cover wet stucco mixture with plastic when idle.
  • Wet cement can cause skin irritation. Always wear gloves and use tools for mixing and applying. Do not use bare hands. If cement gets on your skin, rinse promptly with water.
  • If painting stucco, be certain to choose a paint that is alkaline tolerant and water vapor permeable. Other types of paint will result in peeling and the need to repaint more often. Be sure to allow stucco patch to dry for a week before applying paint.
  • For safety, wear eye protection such as goggles.
  • When making simple repairs, remove loose pieces of stucco before repairing.
  • To help the new stucco bond to the old, wet down the existing stucco before applying the repair mixture.

Stucco is an attractive and tough building material that can stand up over time. By providing regular DIY preventative maintenance, larger and more expensive repairs will be less likely.

Hi, I'm Caroline. Welding has always been really fascinating to me. One day, when I was at work in my office, we had a leaky pipe in the ceiling. After calling a plumber, he called a welder who came to repair the large, open pipe. As we were all sitting there trying to work, the welder just came in and started repairing the pipe! I had never worked on a construction site before, and I probably never will. But I started thinking about what it would actually be like to work on a construction site, which led to me exploring construction themes and writing this blog!
