Professional Deck Coating and Waterproofing
Serving southern California & Surrounding Areas
Why Deck Coating Matters
Protect Structure, Prevent Leaks
A high-performance deck coating is the first line of defense against water intrusion, sun exposure, and daily wear. Properly selected and installed systems seal the surface, bridge minor cracks, resist UV degradation, and create a safer, slip-resistant walking surface—all while elevating appearance. From plywood balcony decks to concrete walkways and roof decks, the right coating prevents costly substrate damage and extends service life.
Water finds the weakest point—at door thresholds, posts, drains, scuppers, and transitions. Without a continuous, reinforced waterproofing layer, moisture can lead to rot, delamination, corrosion, and interior leaks. Dimarco Plastering Specialist and Deck Coating focuses on robust detailing at all penetrations and edges, using proven assemblies that meet industry standards for durability, safety, and long-term performance.
Urethane, Acrylic, Epoxy & Cementitious
We install elastomeric urethane traffic coatings engineered for flexibility, crack-bridging, and heavy foot traffic. These multi-layer systems typically include a primer for adhesion, a reinforced waterproof membrane, aggregate-textured wear coats for slip resistance, and a UV-stable aliphatic topcoat for color retention. Texture and color can be tailored to improve traction, reduce heat buildup, and complement your architecture.
For concrete restoration, we offer epoxy primers and moisture-mitigation options, along with cementitious or acrylic resurfacing to rejuvenate worn substrates before topcoating. For plywood balcony and walking roof decks over occupied space, we install fully reinforced waterproof assemblies that integrate with flashing, door pans, and stucco terminations. Low-VOC options, fire-rated assemblies, and systems tested to relevant ASTM/ICC standards are available to meet project and code requirements.
Inspection, Repair, Installation
Every project begins with a thorough condition assessment. We evaluate substrate type and health, check slope-to-drain, and identify failure points at seams, edges, and penetrations. When needed, we perform moisture testing, replace compromised sheathing or concrete, upgrade edge metals, and integrate new flashings. Surface preparation may include mechanical grinding or shot-blasting, epoxy patching, and proper priming to ensure permanent adhesion.
Installation follows manufacturer specifications and best practices. We apply reinforced waterproof membranes at critical areas, verify wet-film and dry-film thickness, and add aggregate for slip resistance suited to the use case. Posts, rail bases, door thresholds, and drain assemblies are detailed to maintain continuity of the waterproofing layer. Cure times are managed around temperature and humidity so each layer bonds as designed.
Quality control is documented through adhesion checks, thickness readings, and optional water testing on occupied spaces. At closeout, we provide maintenance guidelines covering cleaning, furniture protection, snow shovel equivalents for abrasion control, and recoating intervals—typically 5–7 years depending on exposure and traffic. Warranty options are available based on system selection and service conditions.
