DensiKure Concrete Curing Compound - Bulk

DensiKure Concrete Curing Compound — Cure and Densify New Concrete in One Step

Technical Specifications

PROSOCO DensiKure is a single-product solution that simultaneously cures and densifies newly placed standard gray or integrally colored concrete. By combining the chemistries that densify and harden concrete with those that cure it, DensiKure eliminates the normal wait time between separate curing and densifying steps. It is formulated for interior, smooth, steel-trowel finished concrete slabs and is well-suited for commercial and industrial flooring applications where schedule efficiency is critical.

Unlike conventional curing compounds that only form a moisture-retaining membrane, DensiKure also improves abrasion resistance, reduces surface dusting, and reduces the staining and color variations common to other curing methods. Treated surfaces are typically dry in approximately 60 minutes, allowing follow-on trades to proceed sooner.

Key Features & Benefits

Dual-Action Cure and Densification

DensiKure combines curing and densifying chemistries in a single application, removing the scheduling gap that normally occurs between these two steps. For contractors, this means fewer return visits, less labor, and a faster path to a finished floor.

Meets ASTM C309 Moisture Retention Requirements

DensiKure is compliant with ASTM C309, Type 1, Class A & B on interior steel-trowel finished concrete, giving specifiers and project owners a verified performance benchmark. This compliance simplifies submittal approval on specified projects.

Fast Drying — Surface Ready in ~60 Minutes

Treated concrete floors are typically dry within 60 minutes of application. This rapid drying time keeps project timelines tight and minimizes disruption to other trades working on the same slab.

VOC Compliant, Non-Flammable, Low Odor

With a VOC content below 100 g/L, DensiKure meets EPA AIM VOC regulations and is suitable for sale in all states and districts with more restrictive AIM VOC rules. Its non-flammable, non-toxic, low-odor formulation makes it practical for enclosed interior job sites.

Compatible with Subsequent Coatings and Treatments

DensiKure is compatible with subsequent applications of PROSOCO dyes, stains, coatings, and protective treatments. Contractors who plan to apply decorative or protective finishes after curing do not need to worry about adhesion conflicts.

Easy Application with Standard Equipment

DensiKure applies with low-pressure (<50 psi) pump-up sprayers and requires no dilution or thinning — apply it as packaged. A soft bristle broom or microfiber pad can be used to spread the product evenly across the surface.

Common Applications

New Interior Concrete Slabs

DensiKure is designed for application immediately after finishing on newly placed interior concrete, locking in moisture to enable a complete cure while simultaneously densifying the surface.

Commercial and Industrial Flooring

Ideal for warehouse floors, manufacturing facilities, and large commercial pours where abrasion resistance, reduced surface dusting, and schedule efficiency are priorities.

Data Center Floors

DensiKure is specifically noted as suitable for concrete floors in data centers, where surface quality, dusting control, and chemical cleanliness are important operational requirements.

Integrally Colored Concrete

The product is formulated for use on both standard gray and integrally colored concrete, and helps reduce the color variations that can result from other curing methods.

Floors Receiving Subsequent Decorative or Protective Treatments

When a slab will later receive PROSOCO dyes, stains, coatings, or protective treatments, DensiKure can be used as the curing step without interfering with those follow-on applications.

Application Instructions

Surface Preparation

1. Protect all people, vehicles, property, plants, and surfaces not intended for treatment from product, splash, and wind drift using polyethylene or other proven protective material.
2. Do not apply to surfaces with standing water.
3. For best results, apply DensiKure after finishing and before cutting control joints. If joints have already been cut, remove dust and debris from the surface and joints before application.
4. Confirm that the concrete surface is clean, free of standing water, and absorbent before proceeding.
5. Verify that surface and air temperatures are between 40–100°F (4–38°C). Do not install if rain is forecast during the installation window.

Determine Target Coverage Rate

1. Always test a small, representative area of the surface before beginning full application. Use the same equipment, surface preparation, and application procedures planned for the overall project.
2. Add 1 gallon of DensiKure to a clean pump-up sprayer fitted with a 0.5 gpm fan spray tip (or other approved spray equipment).
3. Coat the concrete surface thinly and evenly with no puddling. A soft bristle broom or microfiber pad may be used to spread the product. Stop spreading once drying begins.
4. Measure the test area to establish the target coverage rate per gallon for the project. Typical coverage is 200–600 sq.ft. per gallon (5–15 m²/L); actual rate will vary based on concrete quality, porosity, temperature, and relative humidity.
5. Allow the test area to dry thoroughly before inspecting results.

Full Application

1. Apply DensiKure as packaged — do not dilute, alter, or thin. Mix well before use.
2. Using low-pressure (<50 psi) pump-type spray equipment, coat the surface evenly with no puddling.
3. A soft bristle broom or microfiber pad may be used to spread the product. Stop spreading once drying begins.
4. Maintain the target coverage rate established during pre-testing across the entire project area.

Storage and Handling

1. Keep from freezing. Store in a cool, dry place with containers tightly closed when not in use.
2. Maintain storage temperatures of 45–100°F (7–38°C). Do not double-stack pallets.
3. Dispose of unused product and containers in accordance with local, state, and federal regulations.

Frequently Asked Questions

Q: Can DensiKure be used on exterior concrete?
A: No. DensiKure is formulated for use on smooth, interior steel-trowel finished concrete only. For exterior concrete curing needs, PROSOCO recommends SingleStep® or SingleStep® WB.

Q: Does DensiKure need to be diluted before use?
A: No. DensiKure should be applied as packaged. Do not dilute, alter, or thin the product. Mix well before use.

Q: When should DensiKure be applied relative to control joint cutting?
A: Ideally, apply DensiKure after finishing and before cutting control joints to minimize potential for tracking and surface dusting. If joints have already been cut, remove all dust and debris from the surface and joints before applying.

Q: How long before the treated surface can be used or receive follow-on coatings?
A: Treated concrete floors are typically dry in approximately 60 minutes. DensiKure is also compatible with subsequent applications of PROSOCO dyes, stains, coatings, and protective treatments once dry.

Q: What coverage rate should I plan for?
A: Typical coverage is 200–600 sq.ft. per gallon (5–15 m²/L). Actual coverage varies based on concrete porosity, quality, temperature, and relative humidity. Always perform a pre-test on a representative section to determine the project-specific target coverage rate before proceeding with full application.

Q: Is DensiKure compliant with VOC regulations in my state?
A: DensiKure has a VOC content of <100 g/L and is compliant with EPA AIM VOC regulations. It is suitable for sale in all states and districts with more restrictive AIM VOC rules.
