Waterproof Coatings
Waterproof Coating Systems We Install
We work with multiple coating technologies and select the right system based on your property’s specific needs:
- Gaco Poly Fast Pass — A rapid-cure polyurea system ideal for occupied properties where fast turnaround is critical. This system can be walked on within hours, minimizing disruption to residents and tenants on balconies and breezeways.
- Pacific Polymers — A trusted line of pedestrian-grade waterproof deck coating systems engineered for long-term performance on balconies, walkways, and parking decks. These systems provide excellent flexibility and UV resistance in Arizona’s extreme climate.
- Epoxy-Based Systems — High-performance coatings for heavy-traffic areas and surfaces that need maximum durability and chemical resistance. We specify epoxy systems for applications where abrasion resistance and structural waterproofing are the priority.
Each system includes a slip-resistant finish texture appropriate for the application, ensuring resident safety while providing reliable waterproof protection.
Common Applications
Our waterproof coating crews work on all types of elevated and exposed walking surfaces found on multifamily and commercial properties:
- Balconies — Private unit balconies on apartment complexes, condominiums, and mixed-use buildings. Failed balcony waterproofing is one of the most common sources of water intrusion complaints on multifamily properties.
- Breezeways & Walkways — Common-area corridors, covered walkways, and open breezeways that see heavy daily foot traffic from residents.
- Walk Decks & Pool Decks — Elevated decks, rooftop amenity areas, and pool surrounds that require both waterproofing and slip resistance.
- Stairways & Landings — Exterior staircases and landing areas where waterproof protection and safety surfacing are critical.
- Parking Structures — Top decks and ramp surfaces on parking garages exposed to weather and vehicle traffic.
Why Waterproof Coatings Matter in Arizona
Arizona’s climate creates a punishing cycle for exposed walking surfaces. Intense UV radiation breaks down unprotected surfaces, while monsoon season delivers sudden, heavy rainfall that finds every crack and failed joint. The extreme thermal cycling — surfaces that reach 150+ degrees during the day and cool rapidly at night — causes expansion and contraction that standard coatings can’t handle.
When waterproof coatings fail on balconies and breezeways, the consequences go beyond the surface. Water intrusion into the structure below leads to wood rot, mold, stucco damage, and interior unit damage — all of which are far more expensive to repair than maintaining a proper waterproof coating system. A proactive coating program protects both your building envelope and your maintenance budget.
Our Coating Application Process
Every waterproof coating project follows a structured process to ensure long-term performance:
- Surface Inspection — We assess the existing substrate condition, identify any structural damage or moisture issues, and determine the right coating system for the application.
- Surface Preparation — Proper prep is critical. We remove failed coatings, repair cracks and damaged substrate, and prepare surfaces to manufacturer specifications for maximum adhesion.
- Primer & Base Coat — Application of the appropriate primer and waterproof base coat system, ensuring proper mil thickness and complete coverage.
- Top Coat & Texture — Final slip-resistant top coat applied with the appropriate texture for the traffic level and application.
- Inspection & Documentation — Post-application inspection with adhesion and thickness verification, plus warranty documentation for your records.
Frequently Asked Questions
How long do waterproof deck coatings last?
With proper preparation and application, commercial waterproof coating systems typically last 8-15 years depending on traffic level, exposure, and the system used. We provide manufacturer warranty documentation with every project.
Can you coat over existing deck coatings?
In many cases, yes — if the existing coating is well-adhered and the substrate is in good condition. We assess every surface and provide an honest recommendation on whether overlay or full removal is the right approach.
How long does the application take?
Timelines vary by scope, but most balcony and breezeway projects can be completed in phases that minimize resident disruption. Systems like Gaco Poly Fast Pass allow foot traffic within hours of application.
Do you work on occupied properties?
Yes. The majority of our waterproof coating projects are on fully occupied multifamily communities. We coordinate phasing and resident communication with your property management team.
