Residential Elastomeric Coating in Boca Raton
Faded, chalky stucco in Boca Raton is a failure of the elastomeric coating's acrylic matrix under South Florida's UV, allowing moisture to reach the substrate.

What Is Residential Elastomeric Coating?
Residential elastomeric coating addresses the protective film that shields your stucco and masonry from UV radiation, moisture, and thermal movement. Not every faded or cracked exterior has the same solution, a chalky surface on a sound substrate needs a different approach than a blistering finish coat over an unresolved moisture source.
UV radiation breaks down the acrylic polymer matrix of an elastomeric coating over time, reducing its elongation and crack-bridging capacity. Thermal cycling at the stucco surface then opens hairline cracks through the weakened film. Once a crack opens, moisture penetrates behind the coating, salt-air chlorides accelerate lath corrosion where the substrate is stucco over metal lath, and repeated wetting and drying cycles cause the coating to blister, delaminate, and ultimately fail. Correct diagnosis determines what comes next.
Standalone elastomeric re-coating
Full exterior coating renewal over sound or freshly repaired stucco, applied to Boca Raton homes on the 7-10 year maintenance cycle that many HOA communities require
Elastomeric coating as final protective layer
Applied after stucco crack repair, delamination repair, or full re-application as the system's waterproof finish
Surface preparation and crack repair
The mandatory prerequisite to any coating application; coating over open cracks or active moisture will fail within a season
Primer application
Manufacturer-specified primer matched to the substrate type and salt-air exposure level of this location
Penetrating silane and siloxane sealers
For above-grade masonry surfaces where a film-forming coating is not the appropriate system
Why Act Now: The Case for Boca Raton Homeowners
Costs significantly less than full stucco removal and re-application driven by moisture damage that a properly maintained coating would have prevented
A failed elastomeric film allows UV and moisture to reach the stucco substrate directly, accelerating cracking and lath corrosion behind the wall
Addresses the source of coating failure, UV degradation, thermal cracking, adhesion failure over a damp substrate, not just the visible blister or chalk
Extends the stucco system lifespan significantly with correctly specified high-build elastomeric coatings rated for Boca Raton's UV load and humidity
Completed in days with minimal disruption to the property and surrounding landscape
Backed by a written workmanship warranty

Frequently Asked
Boca Raton Elastomeric Coating FAQ
The questions Boca Raton homeowners ask most. Tap any to expand.
Standard exterior paint is applied at 3 to 5 mils dry film thickness. Elastomeric coatings are applied at 10 to 20 mils, creating a rubber-like membrane that actively bridges hairline cracks rather than simply covering them. In Boca Raton's climate, with intense UV, high humidity, salt air from the Intracoastal and the Atlantic, and significant thermal movement through summer, standard paint degrades rapidly and provides no crack-bridging capacity. An elastomeric system maintains flexibility and waterproof performance for 10 to 15 years when correctly specified and applied.
A correctly specified and applied high-build acrylic elastomeric system typically delivers 10 to 15 years of effective performance on a Boca Raton stucco home. Homes in direct Intracoastal or canal-front positions, with salt-air exposed east or north-facing elevations, may reach the lower end of that range sooner, particularly if the original coating was under-applied or the primer was omitted. Premium ceramic-blend systems are rated for 15+ year service life and are specified where the homeowner requires an extended recoating interval.
The visible signs that repair is required before re-coating are: blistering or delaminating coating sections, stucco that sounds hollow when tapped behind the coating film, rust staining indicating corroding lath underneath, or interior moisture following rain events. If the coating has simply faded, chalked, or developed hairline surface cracking without any of these signs, direct re-coating over a sound substrate is likely the correct scope. The only way to confirm it is through an on-site assessment. Applying a new coating over an unresolved substrate problem produces a failed coating.
Yes. Old Floresta is Boca Raton's only official historic district, and its Mizner-era properties require coating systems that are breathable and compatible with the original lime-based and Portland cement masonry. Standard synthetic elastomeric coatings applied over historic masonry trap moisture rather than allowing the wall to breathe, causing damage to the original material. As Certified Jahn Applicators, Anthony Pennacchi & Sons is qualified to specify and apply mineral-compatible, breathable coating systems appropriate for Old Floresta properties and other Mizner-influenced homes in Boca Raton.
Yes. Florida law requires a licensed contractor for elastomeric coating and exterior restoration work on residential properties. Anthony Pennacchi & Sons holds a current Florida contractor license and carries full insurance. When evaluating contractors for residential elastomeric coating in Boca Raton, FL, license verification is a basic requirement, not an optional check.
