Stucco Painting: What Homeowners Should Know
Stucco is a natural fit for homes in Western Colorado. It complements our landscape, works beautifully with Southwestern and contemporary architecture, and provides a durable exterior surface. But after years of exposure to intense sunshine, wind, temperature swings, snow, and moisture, even a good stucco exterior can begin to look faded, stained, cracked, or simply outdated.
A fresh coat of paint can completely transform a stucco home. But painting stucco isn't as straightforward as painting a bedroom wall or even traditional siding.
At XL Painting, our crews have seen what happens when stucco is painted correctly, and we've also seen the problems that can occur when preparation, repairs, products, or application techniques are skipped. Before you turn your stucco repaint into a weekend DIY project, here's what you should know.
Stucco Isn't Just Another Surface
One of the biggest mistakes homeowners can make is treating stucco like any other exterior surface.
Stucco is porous, heavily textured, and prone to developing cracks. Traditional stucco and synthetic stucco systems such as EIFS also have different characteristics that can affect how they should be repaired and coated. Professional painting guidance from Benjamin Moore notes that stucco typically requires significant preparation and can require considerably more paint than smoother surfaces because of its texture.
That means a successful stucco paint job isn't simply a matter of choosing a color and breaking out the roller.
The condition of the existing stucco, previous coatings, cracks, moisture, age of the surface, texture, and type of stucco all need to be considered before painting begins.
Preparation Is Everything
When homeowners look at an exterior painting project, the paint is naturally what gets most of the attention. For professional painters, however, much of our attention is focused on what happens before the first finish coat even goes on.
Stucco should be clean, sound, properly repaired, and thoroughly dry before it is painted. Sherwin-Williams notes that paint failure is often a symptom of inadequate surface preparation and recommends that surfaces be clean, solid, and dry before coating.
Depending on the condition of the home, preparation may involve:
Cleaning dirt, dust, chalking, and other contaminants from the surface
Removing loose or failing coatings
Identifying and repairing cracks
Repairing damaged or deteriorating stucco
Addressing areas where moisture may be entering
Allowing repairs and washed surfaces adequate drying or curing time
Protecting windows, doors, roofing, landscaping, concrete, and other surrounding surfaces
Applying the appropriate masonry primer or conditioner when needed
Skipping these steps may save time initially, but it can dramatically shorten the life of the finished paint job.
Those Cracks Shouldn't Just Be Painted Over
Hairline cracks are common on stucco homes, but that doesn't mean they should simply disappear beneath a coat of paint.
Cracks need to be evaluated before painting. Some minor cracks can be addressed with appropriate flexible repair products, while larger cracks or areas of loose or delaminated stucco can require more extensive repair. We recommend repairing stucco cracks before repainting because they can show through the new finish.
This is one reason we recommend having an experienced professional evaluate the exterior.
A painter shouldn't simply make a crack invisible. We want to understand what we're painting over and prepare it appropriately so you're not looking at the same problem again shortly after the job is complete.
Moisture Matters More Than You Might Think
Stucco and moisture can be a troublesome combination when painting isn't handled correctly.
If moisture is trapped behind an exterior coating or the surface is painted before it is adequately dry, homeowners can eventually encounter problems such as blistering, peeling, staining, or coating failure. Moisture in the substrate is a potential cause of exterior paint losing adhesion.
A professional painter knows that the goal isn't simply to create a beautiful exterior. The coating system also needs to be compatible with the masonry surface and the conditions of the home.
That's particularly important in Western Colorado, where exterior surfaces can experience significant environmental exposure throughout the year.
The Right Paint Makes a Difference
Walking into a paint store and choosing an exterior paint isn't enough.
Stucco is a masonry surface, and the appropriate coating system should be selected based on the specific substrate and its condition.
Depending on the project, professionals may use high-quality 100% acrylic masonry-compatible products or an elastomeric coating designed for appropriate masonry applications. Elastomeric coatings can be useful in certain situations because their thicker, flexible film can help bridge some hairline cracking and provide additional protection from water penetration. However, that doesn't mean elastomeric paint is automatically the right choice for every stucco home.
Selecting the right primer, coating, sheen, and application method is part of what you're paying a professional painter to determine.
The most expensive paint in the store won't perform properly if it isn't compatible with the surface underneath it.
Stucco Can Use a Surprising Amount of Paint
Here's something that often surprises homeowners planning a DIY stucco project: you may need much more paint than you expect.
Unlike a smooth wall, stucco contains countless peaks, valleys, pores, and irregularities. All of that additional surface area needs adequate coating.
Depending on the texture, stucco may require 30% to 50% more paint than a typical smoother surface.
This can make DIY cost estimates misleading. What initially looks like an inexpensive project can quickly become much more expensive once additional gallons of premium exterior paint, primer, patching products, masking materials, rollers, brushes, pressure-washing equipment, ladders, and possibly a paint sprayer are added to the list.
And that's before even considering your precious time.
Spraying Stucco Isn't as Easy as It Looks
Watching an experienced painter spray a house can make the process look effortless.
It isn't.
Stucco's irregular surface makes consistent coverage more challenging. Depending on the coating system and surface, professional painters may spray and then back-roll or back-brush the material to help work the coating into the texture and achieve a more uniform finish. Some painters specifically recommend back-rolling or back-brushing after spraying stucco for an even finish.
Professional spray application also requires careful masking and control of overspray.
In Western Colorado, where wind can become a factor quickly, spraying without the proper experience can turn into a mess. Windows, roofing, concrete, vehicles, landscaping, neighboring property, and outdoor furniture all need to be properly protected.
The actual spraying may be one of the fastest parts of the job. The knowledge and preparation surrounding it are what make the difference.
Western Colorado Weather Adds Another Challenge
Our climate is another reason we recommend leaving exterior stucco painting to professionals.
Exterior coatings need the proper conditions to cure and adhere correctly. Temperature, direct sunlight, wind, surface temperature, rain, dew, and moisture can all affect an exterior painting project.
A wall baking in afternoon sun can present very different conditions from the shaded side of the same house.
Professional painters don't just look at the weather forecast and decide, "It isn't raining, so we're good."
We plan the project around the conditions and follow the application requirements of the products we're using. That's an important part of getting the performance homeowners expect from a professional paint job.
Why DIY Stucco Painting Can Cost More in the Long Run
We understand why homeowners consider painting stucco themselves. Painting seems like one of those home improvement projects where you can save a significant amount of money by providing the labor.
Sometimes that's true.
But exterior stucco is one of the projects where mistakes can become expensive.
Poor preparation, improper crack repair, painting over moisture, using the wrong coating, inadequate coverage, overspray, missed areas within the texture, or painting under the wrong conditions can lead to a finish that doesn't perform the way it should.
If that happens, fixing the problem can involve more than simply applying another coat. Failed coatings may have to be removed or stabilized and the surface prepared again before it can be properly repainted.
In other words, doing it twice is rarely cheaper than doing it correctly once.
Professional Painting Is About More Than the Final Color
Of course, you want your home to look great when the project is finished. But a professional stucco paint job should accomplish more than changing your home's color.
At XL Painting, our goal is to provide a finished exterior that looks clean and consistent while giving the underlying surface the preparation and coating system it needs.
That means taking the time to inspect the surface, complete the necessary prep work, protect the areas surrounding the project, select quality products, apply them correctly, and clean up when the job is finished.
It's the work you don't see in the final photograph that often determines how good the finished project will be.
