Where are protective coatings commonly applied?

In commercial and institutional settings, protective coatings are typically used to safeguard concrete and masonry surfaces that face significant exposure to water, salts, chemicals, or freeze-thaw cycles. These coatings are a key asset protection strategy in New England, where seasonal moisture, snow, ice, and deicing salts accelerate deterioration.

Common applications for protective coatings include parking garage decks and ramps, which are highly susceptible to water penetration, chloride intrusion, and abrasion from vehicle traffic. Coatings on these surfaces help prevent corrosion of embedded steel reinforcement and minimize concrete spalling. Similarly, plaza decks and pedestrian walkways benefit from coatings that mitigate water ingress, reducing the risk of leaks into occupied spaces below and helping the structure withstand cycles of freezing and thawing.

Balconies are another high-risk area, especially those with exposed concrete slabs. Here, coatings act as a barrier against water and environmental pollutants, supporting long-term performance and occupant safety. Building facades, including brick, stone, and concrete walls, can be treated with breathable coatings to protect against wind-driven rain and atmospheric contaminants while allowing trapped vapor to escape, essential for maintaining the integrity of historic masonry or older envelope assemblies.

Structural concrete elements such as columns, beams, and parapets are also prime candidates for protective coatings—especially on exposed elevations or rooftop levels where direct weather exposure is greatest. Specialized coatings may also be applied to mechanical equipment pads, below-grade foundation walls, loading docks, and stairwells.

Selecting the appropriate protective coating system requires careful consideration of the building’s location, material composition, anticipated exposures, and maintenance needs. A professional inspection done by ESI Waterproofing & Masonry Restoration, Inc. can identify vulnerable areas and inform coating selection, surface preparation requirements, and ongoing maintenance plans. Proper installation and regular condition assessments are important to maximize the service life of the coating and protect the underlying structure. In New England’s climate, routine maintenance and timely recoating are essential factors in achieving reliable, long-term building envelope protection.
