Why Professional Water Proofing Matters

Stop Moisture Intrusion Before It Starts

Water intrusion is one of the most common and costly sources of building damage. Left unaddressed, moisture can cause mold growth, wood rot, rusting rebar, stucco blistering, efflorescence, and spalling concrete. Professional water proofing preserves the building envelope, protects interior finishes, improves indoor air quality, and safeguards structural integrity.

Dimarco Plastering Specialist and Deck Coating delivers a comprehensive approach that identifies root causes—not just symptoms—of leaks. From substrate evaluation to system selection and detailing, our goal is long-term performance with manufacturer-aligned best practices and clear maintenance guidance so your investment lasts.

Assessment, Preparation, Application, Verification

We begin with a thorough inspection that may include moisture meter readings, infrared scans, and slope-to-drain checks. Critical details such as flashings, transitions, penetrations, and terminations are reviewed. We assess existing coatings, detect substrate failures, and recommend the right system for your specific deck, wall, planter, or below-grade condition.

Surface preparation is meticulous: cleaning, mechanical abrasion, crack chasing, patching, and the installation or repair of flashings and sealant joints. We apply primers and membranes—such as urethane, acrylic, cementitious, epoxy, or elastomeric systems—to manufacturer-specified mil thicknesses, detail all penetrations, and perform quality control checks like adhesion testing and controlled water testing before sign-off.

Decks, Balconies, Stucco, Planters, And Below-Grade

Traffic-bearing deck coatings protect balconies, walkways, and roof decks from UV exposure and foot traffic. We integrate slope-to-drain detailing, door pans, scuppers, and post bases, then apply reinforced membranes and UV-stable topcoats with optional anti-slip textures for safety and durability.

Wall and stucco waterproofing often pairs elastomeric coatings with proper crack-bridging and joint design. We service WRB (weather-resistive barrier) interfaces, repair lath and plaster, address control and expansion joints, and seal parapet caps and terminations with compatible silicone or polyurethane sealants to keep water out of the wall assembly.

For planters, podiums, and below-grade structures, we use negative- and positive-side systems including crystalline, bentonite, and sheet or liquid-applied membranes. Drainage mats, protection boards, and weep systems help manage hydrostatic pressure. We provide maintenance plans, recommended recoat intervals, and documentation to support warranty compliance and long-term performance.
