Painting Stucco and Concrete Block Homes in Orlando, FL

Why stucco and CMU block dominate Orlando construction

Concrete block construction with a stucco finish is the standard for the vast majority of Central Florida homes built from the 1960s onward, found throughout neighborhoods like Baldwin Park, Windermere, Dr Phillips, and newer Lake Nona construction, largely because it holds up structurally well against humidity, termites, and hurricane wind loads compared to wood-frame siding. That durability is a real advantage, but stucco's rigidity also makes it prone to hairline cracking as the underlying slab and block shift slightly over decades, especially in homes over 20-25 years old.

Understanding that your walls are stucco over block, not wood siding, changes the painting approach: the priorities become crack repair, proper primer for masonry surfaces, and moisture management, rather than the sanding and wood-rot repair concerns of a siding-clad home.

Prep steps that matter most on stucco

Pressure washing is the first step and needs to be thorough enough to remove chalking, mildew, and surface dirt without blasting through soft or already-failing stucco, which is a common mistake with too-aggressive pressure settings. After washing, every visible hairline crack should be routed out slightly and filled with an elastomeric or acrylic caulk rated for masonry movement, not just painted over, since paint alone won't bridge a crack for long.

Any efflorescence (white mineral deposits) or areas of spalling stucco need to be addressed before painting, since paint applied over active moisture issues will fail quickly. A masonry-specific primer, rather than a generic exterior primer, helps with adhesion and alkali resistance, since fresh or patched stucco can have a high pH that breaks down standard paint.

Standard acrylic paint versus elastomeric coatings

Standard 100% acrylic exterior paint works fine for stucco in good condition with minimal cracking, and it costs less and is easier to touch up later. Elastomeric coatings are a thicker, rubberized paint system specifically designed to bridge hairline cracks (typically up to about 1/16 inch) and provide a more substantial water barrier, making them a strong choice for homes with a history of cracking or water intrusion, common in older Conway and College Park block homes.

Elastomeric coatings require correct application thickness (measured in mils) to perform as designed; under-application is a common shortcut that leaves the coating without its crack-bridging capability. They also cost meaningfully more, generally $6,500-$12,500 for a typical home versus $4,500-$8,500 for standard acrylic, and are harder to touch up seamlessly later since the texture and thickness differ from a single fresh coat.

Cost breakdown for a typical stucco or block home job

For a single-story stucco home around 1,800 square feet in good condition, budget $4,500-$8,500 for a standard acrylic repaint including basic prep. If crack repair is extensive, add roughly $8-$18 per linear foot of routed and filled cracking. If you're going with a full elastomeric system, budget $6,500-$12,500 depending on home size and existing crack extent, since elastomeric jobs typically also involve more thorough crack prep upfront as part of the system's warranty requirements.

Choosing a contractor for stucco work specifically

Ask any painting contractor how they handle crack repair specifically, do they route and fill with a flexible masonry caulk, or just paint over hairline cracks. Ask whether they're proposing standard acrylic or elastomeric and why, given your home's crack history and any past water intrusion. And get the mil thickness spec in writing if you're paying for an elastomeric system, since that's the detail most likely to get shortcut on a rushed job.
