The application of stucco involves several steps, including initial drying, hydration, surface preparation, and watering. Initial drying typically takes 48-72 hours for a layer of stucco to dry enough for the next coat or painting. Hydration is essential for achieving durable stucco, as it converts portland cement into a solid binder. In dry climates or windy weather, keeping the stucco moist for at least 48 hours after application is crucial.
To prepare the surface, ensure it is clean and free from dirt, oils, paint, and old materials. Moisture-cure the stucco, which should be 3/8 inch thick and moisture-cure for 48 hours before the brown coat is applied. In dry climates or windy weather, keep the stucco walls moist in the morning and evening when the walls are cool.
The best curing method is surface-misting with water, which involves lightly misting the surface of each layer of plaster two to four times daily. Applying an even coat of water to the newly stucco’d walls for 2-3 days can help reduce cracking.
Waterproofing a stucco finish requires a multi-step process that provides high resistance to water intrusion while allowing water vapor to easily escape. Most manufacturers don’t recommend painting stucco unless the pH level is 10 or below. Overall, understanding the intricacies of the stucco drying process is essential for achieving a smooth and durable finish.

How do you wet cure stucco?
Stucco walls should be kept moist for 48 hours after application, and watered in the morning and evening when the walls are cool. This allows the hydration process to continue and the stucco to harden. The hydration process begins with blending stucco in a mixer, which should be mixed for at least 5 minutes (concentrate) or 3 minutes (premix). Empty the entire mixer after each batch, as all particles are coated with water during mixing. Over-mixing can weaken the stucco by entraining air.
What is the best way to seal stucco?
The Iso-Tek 8100 is an industrial grade penetrating concrete sealer, best used as a water repellent on natural stucco or as a primer and bonding agent for painted stucco. It is the highest performing product in the product line and requires application before painting. If painted, the paint must be removed. The sealer can be applied seven days after sealing and acts as a bonding agent, increasing the ashesion of the paint applied to the stucco.
How long does it take stucco to dry cure?
Before applying stucco, it’s crucial to consider the weather conditions. Stucco typically drys for 48 hours before being exposed to rain or foggy weather, and it takes about 90 days for it to dry completely.

Can fresh stucco get wet?
Wetting stucco is crucial for its proper curing and longevity. It must remain in constant moisture for at least 48 hours after installation. Proper maintenance and installation can extend stucco’s lifespan over 50 years. To properly wet stucco, it is essential to know how to apply water. Stucco, an emulsion of sand, lime, and cement, requires water to create a paste-like consistency. Water helps create a paste by coating the particles in the stucco mix.
After the paste has cooled, apply it in a three-quarters of an inch layer. If the paste is not applied sufficiently, it won’t fully harden. Understanding how to apply water to stucco and addressing rain damage can help ensure its longevity.
Will painting stucco make it waterproof?
Elastomeric-modified paints offer excellent weather resistance properties for painted stucco. To prepare stucco for painting, follow these simple steps: wash exterior walls with mild detergent, rinse well, and let them dry. If pressure washing is desired, consult the 10-Step Guide to Pressure Washing – The Right Way. Make necessary repairs, choose a primer compatible with the substrate and paint system, prime surfaces, and let them dry before applying the paint.
If painting new stucco, allow it to cure and dry for 90 days before applying the primer, letting it dry, and painting the walls.

How do you dry stucco quickly?
The speaker presents a comparative analysis of the efficacy of snowblasted blades, delineating the advantages of the latter method in facilitating faster drying, contingent on meteorological conditions.
Can new stucco get wet?
Stucco must dry over 48 hours before rain, depending on the installation process. This time can affect the drying process by making the mix too moist, causing it to slip off the wall, or altering the appearance of the stucco. If expecting rain, cover the stucco with plastic or tarp, or use an accelerator to speed up drying several days before. Wet stucco may indicate water infiltration, which can occur due to various reasons, such as improper installation, improper maintenance, or weather conditions. To prevent water infiltration, it is essential to follow proper drying procedures and use appropriate materials and techniques.
What happens if you paint stucco before it cures?
The ideal time to paint stucco depends on factors such as the surface’s dry time, moisture availability from rainfall, humidity, and the application itself. High pH stucco can cause color burnout if painted too soon, so there is no rule of thumb regarding the amount of time it takes to cure. Manual hydration and rainfall can help lower the pH level and speed up the curing process. The most important dynamic is the extent of the stucco’s curing and its pH level, not the time since the application. Water is a vital catalyst in the chemical reaction that helps the material harden and cure, so it is recommended to moist-cure over several days.
Should stucco be sprayed or rolled?
Stucco can be painted using a roller or an airless sprayer, with a brush not recommended. A roller is suitable for small jobs but can be overwhelming on larger projects. For larger jobs, consider using an airless sprayer. Use a deep nap roller (3/4 to 1″) to work the paint into the surface for a uniform surface. Stucco typically requires two coats due to its high absorption and to conceal cracks and other repairs. A deep nap roller is recommended for a uniform surface.
Should I waterproof stucco?
Waterproofing is crucial for the exterior of any structure, as it prevents moisture damage and ensures protection from moisture. Installing waterproof stucco requires careful attention and precise techniques. Some homeowners may prefer alternative siding materials with easier water management strategies, as the installation process is laborious. To learn how to waterproof stucco, familiarize yourself with various siding alternatives that offer faster and easier waterproofing.
Can you spray stucco with water?
To reduce cracking in newly installed stucco, apply an even coat of water to the walls for 2-3 days after installation. Use a fan-style hose attachment or your thumb to gently and evenly coat the walls, allowing the color coat to cure evenly and relieve stress on the wall. Avoid slamming doors or windows during the first few weeks to prevent cracking. Properly installed stucco requires minimal maintenance year-round.
To prevent dirt from splashing onto the wall for the first 30 days, lay down cover plastic on splash zones or redirect sprinklers. Once the contractor has finished their work, ask for extra plastic to use during rains. This will help prevent dirt from getting trapped in the texture and making it difficult to clean off the wall. Properly installed stucco requires minimal maintenance year-round.

Hey Kirk – I just wanted you to know how much I appreciate all your great articles and information. I am doing a full remodel. Stucco was one of only three tasks we are outsourcing as DIY’rs and because I understood stucco so well after perusal your articles, I was able to select a great contractor. Thank you for the willingness to share your information. Keep up the great work!
Hello Kirk love all your articles! Had a scratch coat applied about 10 days ago and my contractor has me hydrating it twice a day. Is this still necessary after the 2 days you mentioned? Brown coat will be applied in a couple days. Should I just give it one good soaking a day or continue with twice a day? Thank you
I had never stuccoed before, but after perusal Kirk for 2 years, I decided I’d try it on my own house. Any questions I had, he either had a article for it, or he answered them in the comments. I’m really proud of how it turned out. The only thing I messed up on is two of the windows aren’t “sharp.” 😢 I should’ve caught that. But I couldn’t have done everything else without Kirk!
Kirk, I was trying to start my finish coat today, but stucco would not stick to the brown coat ? I was using a stucco that you had to mix in sand and I mixed 3-1 as bag and you stated. Wet wall prior to installing. But notice this was harder to spread than the brown coat. Wanted to try and spread thin, but found very hard to do. I lost faith in my mix and scrapped a whole batch. Not sure why it kept falling off.
Expat living in the Philippines and trying to Find expert advice here is like looking for a real hamburger at a Vegan Venue. Wall Heat is the problem and the only available solution is metal double backed insulated panels that are epoxy painted. Like Cold storage Panels. I am going to use these as a thermal break in a concrete post and beam residential structure. QUESTION: what method do i use to provide an exterior, as well as interior( for mechanical attachments), concrete face. Mesh mechanically attached via sheet metal screws? Do you have another solution. Thanks
I’m a retired terrazzo mechanic and mason. I was also an architectural precast manufacturer. We recently had lath,scratch and brown done on a house we’re selling. The brown went on the day after the scratch. I questioned it,but they said it was ok. My hunch is that the scratch was still green and not sufficiently cured. We now have many multiple long hairline cracks across the brown coat. They wanted to do color coat a week after and I told them to wait and let it cure. I used this company before on another house and they let things cure longer. It was a good end job with minimal cracks after 3 years. Same process. Sto color coat. My question is, should they do a thin bonder coat or maybe mesh strips over the cracks before the color coat? I understand cementitious surfaces can crack, but I’m concerned the cracks will follow through to the final color coat. Suggestions? Thanks 🙏🏼
I’ve been working on an old building for years. Kirk and Jason’s articles have given me the information to get some of the aging stucco and plaster repairs done and not just cover it all with drywall. It’s a concrete structure with stucco outside and cement plaster inside. I’d love to share photos of the progress with you guys. I’ve got a LONG way to go, but by the time I’m done, she’ll be the beautiful structure she once was.
