Signs to watch
Is this you?
Hairline cracks spidering across the stucco
Fine cracks are normal as stucco cures and moves with temperature. They still have to be filled before paint, or water finds them and works behind the coating over the wet season.
White chalky crust bleeding through the surface
That's efflorescence — salts carried out by moisture moving through the masonry. Paint over it and the coating fails from behind. It has to be removed and the moisture source understood first.
Old paint peeling in sheets off the wall
On masonry, peeling almost always means the last coating trapped moisture that couldn't escape, so it pushed the paint off. The fix isn't more paint — it's a breathable system that lets the wall dry.
Faded, blotchy, or previously patched stucco
Sun and rain flatten masonry color and patches rarely match. A uniform breathable coat evens it out — once the surface is sound and the cracks are dealt with.
Your options
Breathable coatings matched to masonry
Masonry isn't siding — it holds and releases moisture, so the coating has to breathe. We use permeable Sherwin-Williams masonry and acrylic systems that shed rain from the outside but let vapor escape from the inside, instead of the impermeable films that trap water and peel. Prep is the job: wash off chalk and biological growth, remove efflorescence and find why it's there, fill hairline cracks with a flexible patch that moves with the wall, and prime bare or patched areas. Get the breathability wrong and you seal moisture into the wall.
The method
How we do it
- 01
Assess moisture and cracks
We check for active moisture, efflorescence, and the pattern of cracking, then tell you honestly whether the wall needs simple crack repair or a moisture source addressed before any paint goes on.
- 02
Clean, repair, and prime
Wash and let the masonry dry, remove efflorescence, fill hairline cracks with flexible patching that moves with the wall, and prime bare and repaired areas so the coating bonds evenly.
- 03
Apply the breathable coat
A permeable Sherwin-Williams masonry coating applied at proper coverage — uniform color that sheds rain while letting the wall dry, then a walk of the whole exterior together.
Straight numbers
What drives a stucco repaint
Price follows the surface, not the paint. What moves the number: how much crack repair and patching the stucco needs, whether efflorescence points to a moisture source that has to be solved first, wall square footage and texture depth (heavy texture drinks more coating), stories and access, and how sound the existing paint is. A wall that just needs washing and a breathable coat is a very different number from one fighting years of trapped-moisture failure — and we'll tell you which one you have before we quote.
Where we do this work
Stucco & Masonry Painting: straight answers
Can't I just use regular exterior house paint on stucco?
You can, and it's a common mistake. Standard films that work on siding are often too impermeable for masonry — they trap the moisture stucco naturally carries, and it pushes the paint off from behind. Breathable masonry coatings shed rain but let the wall dry, which is why they last where regular paint peels.
Do the hairline cracks need to be fixed, or will paint cover them?
They need to be filled first. Paint bridges the width of a hair, not a moving crack — the coating splits again and water gets behind it. We fill hairline cracks with a flexible patch that moves with the wall so the coating stays intact through the wet-dry cycle.
What is the white powder on my stucco and will painting stop it?
It's efflorescence — mineral salts left behind as moisture moves through the masonry and evaporates. Painting over it just fails from behind, because the moisture is still moving. We remove it and figure out where the water's coming from first, then coat a sound, dry wall.
Is elastomeric coating better for stucco than regular masonry paint?
Sometimes — elastomeric is thick and bridges hairline cracks, which is useful on some stucco. But it's much less breathable, so on an already-damp wall it can trap moisture and cause the peeling it was meant to prevent. We'll tell you honestly whether your wall is a breathable-coating job or a genuine elastomeric candidate.
