Stucco is a popular exterior finish many people use due to its durability, insulation properties, and aesthetic appeal. However, one of the most common issues homeowners face with stucco is the development of cracks over time.? 

Stucco cracks can not only detract from the appearance of your home but can also lead to moisture infiltration and other damage if left untreated.? 

Fortunately, there are several preventive measures you can take to avoid stucco cracks and keep your home looking its best. This article will explore some of the most effective ways to prevent stucco cracks. We’ll also discuss when to call in?stucco repair contractors. 

Mix Proportion? 

This implies how stucco acts on the application, drying, and curing. Notably, the water-to-cement ratio commands the stucco’s workability and the chances of cracking. To resolve this, you need the standard ratio of the manufacturer. Another way to examine the workability and consistency of a new stucco is to utilize the slump test. This type of test is also used to gauge the concrete’s workability. If the stucco maintains its shape after removing the cone, it has the right consistency.?? 

Control Joints? 

One of the main reasons stucco cracks happen is because of the movement produced by mechanical and thermal stresses, including movement or twisting of framing, building settlement, impact, vibration, etc. In several instances, the movement could result in small stucco cracks growing at high-stress points like the upper corners of windows and doors. Now how can we resolve this? Though it’s impossible to stop cracking from the whole stress force that happens while constructing stucco, the danger of cracking could be significantly minimized by setting up control joints, which will deflect the movement stresses. This can help reduce the likelihood of stucco cracks spreading and developing. While constructing a new house, you can install expansion joints to offer perimeter relief in wall systems.?? 

Drying Shrinkage? 

Most stucco cracks progress due to too much water evaporation from the stucco. For example, the extremely high temperature during the summer season can make water evaporate more rapidly from the stucco, which leads to hairline cracks and drying shrinkage. Most of such cracks only show an aesthetic problem. However, too much-cracked stucco won’t be able to effectively secure your business or home from the elements. To minimize the possibility of drying shrinkage cracking, the preventative measures below must be done:? 

  • Use a cement-compatible polymer for your freshly treated stucco, then trowel a fiberglass mesh in it.?? 
  • Prevent drilling and some operations that might minimize vibration on the curing duration.? 
  • Your freshly applied stucco must be damped-cured in dry and hot weather conditions.? 
  • Stick to the suggested mix ratio from the manufacturer and prevent cement-rich mixes.? 


Preventing stucco cracks requires careful attention to the installation process, regular cleaning of stucco, upkeep, and a willingness to address any issues promptly.? 

By following the preventive measures outlined in this article, you can help ensure that your stucco remains in excellent condition for years to come, protecting your home from moisture damage and maintaining its aesthetic appeal.
