SingleStep WB Concrete Curing & Weatherproofing Blend - Pallet of 32 Units

PROSOCO SingleStep WB – One-Step Concrete Curing & Weatherproofing Compound

PROSOCO® SingleStep® WB is a water-based acrylic-silane blend engineered to cure and weatherproof new concrete in a single application. Formulated for contractors working on high-performance concrete structures, it quickly penetrates to form a water-repellent gel within the pores and a semi-glossy film on the surface. This film retains moisture in the slab, allowing the concrete to reach maximum hardness while simultaneously building chemical and water resistance. It meets the requirements of ASTM C309, Type 1 Classes A & B and AASHTO M-148, Type 1, Classes A & B.

Unlike traditional curing compounds that require costly, time-consuming water curing and removal steps, SingleStep® WB eliminates that extra labor entirely. Water repellency begins within 24 hours of application and continues to increase for up to 72 hours, giving treated surfaces durable, long-term protection against water infiltration, deicing salts, and chemical attack.

Key Features & Benefits

One-Step Curing and Weatherproofing

SingleStep® WB handles concrete curing and weatherproofing simultaneously in a single application, eliminating the need for separate products or processes. For contractors managing tight schedules, this directly reduces labor hours and material costs on the job site.

Rapid Water Repellency Development

The product beads water after just 24 hours and continues building water repellency for up to 72 hours post-application. This fast performance means treated slabs are protected against moisture intrusion very shortly after finishing, even in active job site conditions.

Dual-Action Penetration and Film Formation

SingleStep® WB penetrates into the pore structure to form a water-repellent gel while simultaneously leaving a semi-glossy film on the surface. The surface film locks in concrete moisture to support proper hydration and maximum hardness development, while the subsurface gel provides lasting protection.

Protection Against Deicing Salts and Chemicals

Once cured, treated concrete resists damaging water penetration, salts, and deicing chemicals. This is especially valuable in parking garages and northern-climate infrastructure where repeated salt exposure is a primary driver of premature concrete deterioration.

Eliminates Costly Water Curing and Removal

Traditional curing compounds often require water curing regimens and subsequent removal before the surface can be used or coated. SingleStep® WB removes that step entirely, offering a faster path from pour to finished slab.

Silane Ingredient Retention

The formulation is designed to prevent loss of silane ingredients due to evaporation, ensuring the active chemistry stays in the concrete where it is needed for maximum repellency performance.

Broad VOC Regulatory Compliance

SingleStep® WB is compliant with EPA AIM VOC regulations and is suitable for sale and use in all VOC-regulated states and districts except California's SCAQMD. Contractors working across multiple states can rely on this product without sourcing region-specific alternatives in most markets.

Common Applications

Parking Garages

Parking structures face constant exposure to vehicle traffic, water intrusion, and deicing salts. SingleStep® WB provides the chemical resistance and moisture barrier needed to extend the service life of garage slabs and decks.

Athletic Stadiums

Stadium concrete must withstand heavy foot traffic and outdoor exposure. SingleStep® WB cures the slab to maximum hardness while weatherproofing the surface against rain and cleaning chemicals.

Engineered Concrete Structures

For spec-driven projects requiring ASTM C309 or AASHTO M-148 compliance, SingleStep® WB meets both standards, making it a suitable choice for bridges, transit infrastructure, and other engineered applications.

Sidewalks

Exterior flatwork such as sidewalks benefits from SingleStep® WB's rapid water repellency development and resistance to freeze-thaw cycles driven by water and salt infiltration.

Interior Concrete

SingleStep® WB is also suitable for interior concrete surfaces, providing curing and protection in warehouse floors, interior slabs, and similar environments. (Note: for interior steel-troweled concrete, PROSOCO's DensiKure may be more suitable — consult product documentation.)

Application Instructions

Surface Preparation

1. Protect people, vehicles, property, plants, windows, and all non-masonry surfaces from product, splash, residue, fumes, and wind drift.
2. Protect and/or divert foot and vehicle traffic from the work area.
3. Ensure fresh air entry and cross ventilation during application and drying.
4. Extinguish all flames, pilot lights, and other potential ignition sources during use and until all vapors are gone.
5. Confirm concrete surfaces are clean and structurally sound.
6. For new concrete, wait at least 3 hours after the freshly poured concrete has received final finishing and all surface water is gone before applying.
7. Verify surface and air temperatures are at least 40°F (4°C) and should not exceed 90°F (32°C) during application and for 8 hours following. Apply to shaded surfaces and before daytime temperatures peak.
8. Do not apply if subfreezing temperatures are expected — freezing will inhibit penetration and significantly impair results.

Equipment Setup

1. Use high-volume, low-pressure spray equipment (less than 50 psi) as the recommended application method.
2. Fit spray equipment with neoprene fittings.
3. Use fan spray tips to avoid atomization of the material.
4. For small-scale application or where spray is not appropriate, product may be applied by brush or roller — contact PROSOCO Customer Care or your local representative for guidance.
5. Ensure all application equipment is clean and dry before use.

Storage and Handling

1. Keep from freezing.
2. Store in tightly sealed, original factory containers in a horizontal position to prevent moisture accumulation on the drumhead.
3. Store in a cool, dry place and keep tightly closed when not dispensing.
4. Shelf life is 2 years in a tightly sealed, unopened container under proper storage conditions.
