Best Exterior Paint for Stucco: A Complete Guide

Stucco is a popular plaster material used to mold architectural decorations, coat walls, and texturize drywall. It’s a fantastic option for a home’s exterior since it has a very high resistance to precipitation and UV radiation.

The best exterior paint for stucco

Below, we’ll go over all of your options and show you how to pick the best stucco paint for your home’s exterior.

Things to Look for When Choosing the Best Exterior Paint for Stucco

There are three types of stucco paint: masonry, elastomeric, and acrylic. While you can use other paint formulas that may adhere to stucco, those are more susceptible to chipping, bubbling, and peeling than the three above-mentioned paints.

Acrylic

Among the three types, acrylic is the most permeable, meaning it penetrates further into stucco than the other paints. Because of this, moisture can escape from stucco as opposed to forming ugly bubbles underneath the paint.

Acrylic offers an affordable option and has great durability and color longevity. It also comes in an expansive range of different colors and finishes while drying faster than either elastomeric or masonry paint. However, it does not have the same bonding strength as the other two paints. It also lacks the high waterproofing quality of elastomeric paint.

Masonry

Masonry paints are designed to bond with cinder blocks, concrete, masonry substrates, and stucco. These are very durable and highly mildew- and moisture-resistant. However, these paints offer a limited variety of colors and lower coverage than acrylic paints.

Elastomeric

Elastomeric is basically a rubber paint that’s applied in a liquid form to later dry as a layer of solid rubber. When it comes to water resistance, it’s the best choice. And the paint’s thick formula is one of the limited options available to conceal hairline cracks found in stucco surfaces.

However, these paints do not provide the same glossy or vibrant color appearance and may take a maximum of 72 hours to cure completely. Elastomeric paint also has bonding issues with stucco. Since stucco would already have several paint layers, the weight of elastomeric paint can cause the older paint layers to pull away from the stucco.

Durability

The number of coats applied, formula, finish, and viscosity of exterior stucco paint can influence its durability.

Viscosity

Viscosity represents a great indicator of a stucco paint’s durability. Generally, the thicker the viscosity of the paint, the more durable it will be after it cures fully. Viscosity can also indicate good coverage since thicker paints can conceal small chips and cracks.

Formula

The primary determinant of any paint’s durability is its formula. For instance, acrylic paints represent the most breathable out of the three formulas and have a high resistance to peeling, chipping, fading, and bubbling.

However, masonry paints bond better with masonry surfaces like stucco, but they are not as flexible or breathable as acrylics, which increases the likelihood of peeling and cracking. Finally, elastomeric paints are highly durable and very moisture-resistant but take longer to cure.

Finishes

Exterior paint for stucco has four basic finishes: satin, flat, gloss, and semi-gloss. Flat is the most commonly used for stucco since it helps conceal tiny imperfections that the glosser finishes only highlight.

How Many Coats of Stucco Paint Will You Need?

The rule of thumb is that the more coats of paint you apply, the more durable your results. However, keep in mind that paint carries weight, and with each successive coat, you increase the cumulative weight. This means the layers may reach a point when the first coat is no longer strong enough to adhere to the stucco. If this happens, the paint will begin to peel away from the stucco, which could cause surface damage.

While this is a rare scenario, a paint’s weight should be factored in, especially when dealing with elastomeric paint, which is often the heaviest out of the three mentioned. If you have to work on a wall that already has many layers of paint, you may be better served to remove a few layers with a paint scraper before you repaint.

Weather Resistance

All exterior paints are specifically formulated to withstand outdoor elements such as snow, UV rays, rain, and fluctuating temperatures. However, there are different levels of weather resistance among the above-mentioned paints.

By far, elastomeric paint represents the most weather-resistant paint. The rubber in the paint does a fantastic job sealing out moisture, and the thicker viscosity will protect stucco from UV damage. To help the elastomeric paint better bond to your stucco, it’s best to use a high-quality exterior primer.

VOCs

Volatile Organic Compounds, or VOCs, are damaging chemicals often found in exterior paints. VOCs can have possible negative effects on the human body, including nausea, headache, airway irritation, and even kidney, liver, or central nervous system damage. So it’s safe to say that the best exterior paint for stucco contains few to no VOCs.

Some believe the harmful side-effects of VOCs are not as much of a problem with exterior paints since they are only used outside where fumes escape. However, it’s smart to keep your exposure to VOCs to a minimum no matter what. It’s a good idea to wear a respirator when working with these paints, even if working outside.

Color Endurance

Color longevity is a very important factor when choosing a good stucco paint. If longevity is your most important criterion, acrylic paint is going to be your best option because the paint permeates deepest into the stucco. Elastomeric and masonry paints are fantastic when it comes to bonding to stucco and sealing out moisture, but not as effective at retaining bright, clear colors because they simply do not permeate as deeply.

You also may want to keep in mind that the specific paint color itself may impact its resistance to elemental factors like direct sunlight. Darker colors start to fade more noticeably compared to lighter shades. For instance, if you wish to paint your home’s stucco exterior in a dark hue, you should look for a product that has titanium dioxide, a helpful additive designed to resist color fade. If you have older stucco that’s noticeably dirty, you might consider a paint with a high-hiding formula that will conceal stains.

Dry Time and Coverage

The drying time and coverage typically depend on very specific formulations. You should check the information on the product along with the manufacturer’s recommendation for use to learn the total paint coverage per gallon. This info should also reveal just how long it will take for the product to cure fully.

Acrylic paints for stucco offer higher coverage than elastomeric or masonry paints, usually covering around 300-400 sure feet per gallon. The other two, on average, only cover around 75-125 feet per gallon.

Both masonry and acrylic paint have relatively fast cure times of about 24 hours, while elastomeric paint may take up to 72 hours to cure fully. It would be best to keep in mind that low temperatures and high humidity can increase your cure time.

Preparing the Surface and Application

Before painting your exterior stucco, you must properly prepare it to achieve the best results. This also includes your exterior stucco walls. First, patch any holes or cracks, then sand your patches. Also, sand away any bubbling, peeling, or chipping paint. After making the necessary repairs, wash down your stucco walls using a power washer set on low to remove debris and dirt. Cleaning your stucco will help create stronger adhesion between your exterior and the paint.

Using a Paint Sprayer to Paint Stucco

If the product you pick isn’t a primer-paint combo, apply the appropriate exterior primer on your stucco before you paint. While you can apply the exterior paint using either a roller or brush, you may want to consider a paint sprayer for faster and better dispersal. Plus, these sprayers are excellent at delivering paint into creases and divots commonly found on stucco walls.
