Exterior Painting in Stone Mountain, GA

Stucco walls can look tired long before they fail: hairline cracks, gray streaks under windows, a chalky surface that rubs off on your sleeve. Exterior painting in Stone Mountain on a stucco house can refresh all of that, but only if the coating suits the wall system underneath. Traditional cement stucco and synthetic stucco look alike from the curb and need different handling.

Telling the two apart comes first, because it shapes how cracks and joints are treated, which coatings fit, and when a wall needs more than paint.

Hard-coat stucco or EIFS?

Traditional stucco is a cement-based plaster applied in layers over lath, and it feels rock-hard. Synthetic stucco, known as EIFS, is a thin acrylic finish over a mesh-reinforced base coat on foam insulation board. A gentle knock tells them apart: hard-coat stucco sounds solid, while EIFS sounds hollow and the surface gives very slightly under firm thumb pressure. Looking at the bottom edge or around a utility penetration can confirm it.

Knowing which system you have shapes every product choice that follows.

Hairline cracks and wider ones

Fine cracks in cement stucco are common and usually come from normal shrinkage and movement. They are cleaned out and filled with a flexible patching compound or bridged with a thick primer made for masonry, so they do not reappear through the new coat as quickly. Wider cracks, stepped cracks or cracks that keep growing can point to movement or water problems and are noted for closer evaluation.

Patches are textured to match the surrounding finish before painting. A smooth patch on a sand-textured wall stands out even under fresh paint.

Coatings that suit each wall

Cement stucco needs a coating that lets moisture escape. A masonry primer followed by an exterior acrylic designed for masonry is a common system. Elastomeric coatings, which go on thick and stretch over fine cracks, are another option for hard-coat stucco, though they breathe less, so the wall should be dry and sound before they are used.

EIFS makers specify which coatings are compatible with their finish, often acrylic products intended for that surface. Their recommendations come first, because the wrong coating can trap moisture in the system or fail to bond. Chalky or faded surfaces of either type are washed and dried before priming.

Where stucco meets windows, trim and the ground

The joints around windows, doors, light fixtures and the roofline are where water most often gets behind stucco. Those perimeter joints should have a flexible sealant over a foam backer rod, not hard patching material. Cracked or separated sealant is cut out and replaced with a product rated for the movement and the materials it joins.

Other interfaces must stay open. The metal weep screed along the bottom of a stucco wall lets water drain out and should never be filled with sealant or buried in mulch. Where a roof meets a stucco wall, a small kick-out flashing should send water into the gutter rather than down the wall.

Mildew, streaks and rusty accessories

Textured stucco holds dirt and mildew, especially on shaded walls and below windowsills. A mildew wash and a gentle rinse clean it without blasting the texture away. Metal corner beads, casing beads and weep screeds can rust where their coating has worn, leaving orange stains on the wall. The rust is cleaned, the metal gets a rust-blocking primer, and stains are treated before the finish coats so they do not bleed through.

When paint is not the answer

Soft spots, bulges, stains that keep returning below windows, or stucco that sounds different in one area can indicate water behind the wall. Painting over those areas hides them without fixing them. If we see signs like that, we recommend having the wall evaluated by a stucco or EIFS specialist, and moisture testing if needed, before painting goes ahead.

Questions about painting stucco in Stone Mountain

Should hairline cracks in stucco be filled before painting?

Yes, in most cases. Even fine cracks let water into the wall and tend to show through new paint. They are cleaned and filled with a flexible patching product or bridged with a thick masonry primer, then textured to match. If cracks are wide, stepped or growing, the cause should be looked at first, since filling them will not stop the movement behind them.

Can elastomeric coatings be used on synthetic stucco?

Only if the EIFS maker approves them. Elastomeric products are thick and less breathable, and on some synthetic stucco systems they can hold moisture inside the wall. Many EIFS makers recommend specific acrylic coatings instead. Checking the system’s documentation, or identifying the maker from the house records, is the safest way to choose a compatible product.

How long does new stucco need to cure before it is painted?

Fresh cement stucco needs time to cure and dry before paint goes on, typically several weeks, and its surface is very alkaline at first. Painting too soon can cause blotchy color or poor adhesion. The plaster and paint makers’ guidance sets the waiting period, and some primers are made to go on sooner over fresh masonry. Patches on older stucco also need curing time before painting.
