Prosoco Consolideck LS Lithium Silicate Concrete Densifier

Prosoco Consolideck LS Lithium Silicate Concrete Densifier — Premium Hardener, Densifier & Sealer for Concrete Surfaces

Consolideck LS is a penetrating lithium silicate concrete densifier and hardener designed for contractors and trades professionals working with polished, troweled, or finished concrete floors. It chemically reacts with the concrete substrate to produce insoluble calcium silicate hydrate within the concrete pores, permanently increasing surface density, hardness, and abrasion resistance. The result is a surface that resists dusting, repels water, and requires less ongoing maintenance — making it a critical step in any concrete polishing or hardening workflow. Consolideck LS is well-suited for commercial, industrial, institutional, and data center floor applications.

Unlike conventional sodium or potassium silicate hardeners, Consolideck LS uses a lithium silicate active ingredient that will not trigger or contribute to surface Alkali Silicate Reaction (ASR) — a common failure mode with competing products. Application is a true one-step process with no scrubbing, no flushing, and no caustic wastewater to manage, making it faster, safer, and easier to use on the jobsite than traditional alternatives.

Key Features & Benefits

Lithium Silicate Chemistry — No ASR Risk

Consolideck LS is formulated with lithium silicate rather than sodium or potassium silicate, which eliminates the risk of triggering or contributing to surface Alkali Silicate Reaction (ASR). ASR can cause surface degradation and product failure with conventional densifiers. For contractors working on critical or long-term flooring projects, this distinction is significant.

One-Step Application — No Scrubbing, No Flushing

Consolideck LS is applied in a single step with no scrubbing, no flushing, and no caustic wastewater generated. This simplifies the application process, reduces labor time, and eliminates the need for secondary cleanup equipment or wastewater management on the jobsite.

Eliminates Dusting and Increases Surface Hardness

The increased surface hardness imparted by Consolideck LS permanently eliminates concrete dusting — a common problem in warehouses, manufacturing facilities, and other high-traffic environments. Treated surfaces are easier to maintain and produce a cleaner, healthier working environment for building occupants.

VOC-Compliant, Non-Flammable, Non-Toxic, Low-Odor

Consolideck LS has a VOC content of 0 g/L and is compliant with CARB 2007 and CDPH Standard Method v1.2-2017, making it suitable for interior use and eligible for LEED v4.x, LEED v5, CALGreen, WELL v2, and Living Building Challenge certifications. Its non-flammable, non-toxic, low-odor formulation allows use in occupied or sensitive environments including data centers and institutional facilities.

Broad Finish Compatibility

Consolideck LS is compatible with broom-finished, steel-trowelled, power-trowelled, and burnished concrete finishes, giving contractors flexibility across a wide range of project types and surface conditions. Coverage rates of 500–1,000 sq ft per gallon accommodate varying substrate porosity and application requirements.

Green Building Program Support

Consolideck LS carries SCS Indoor Advantage Gold certification, a Health Product Declaration (HPD), a Declare label (LBC Red List Free), and an Environmental Product Declaration (EPD, Declaration #: SmartEPD-2025-001-0716-01). These credentials directly support documentation for LEED v4.x, LEED v5, CALGreen, Living Building Challenge 3.x, WELL v2, and Fitwel certifications, reducing submittal burden for project teams.

Common Applications

Data Center Floors

Consolideck LS is specifically recommended for data center floor applications where dust elimination, surface hardness, and ASTM F150 electrical static dissipative compliance are critical requirements. Its low-odor, non-toxic formulation allows use in sensitive, occupied environments.

Warehouse and Industrial Floors

High-traffic warehouse and manufacturing floors benefit from the increased abrasion resistance and dust elimination that Consolideck LS provides. The simplified one-step application minimizes downtime during floor treatment.

Polished Concrete Systems

Consolideck LS is a standard densification step in concrete polishing workflows, used prior to final polish passes to harden the surface and improve finish clarity. It is compatible with all common finish types encountered in polishing projects.

Institutional and Educational Facilities

Schools, universities, and other institutional facilities with polished or finished concrete floors benefit from the cleaner, lower-maintenance surfaces produced by Consolideck LS. The non-toxic, low-VOC formulation supports healthy indoor environments.

Commercial Retail and Office Interiors

Retail and office interiors with decorative or polished concrete floors can be treated with Consolideck LS to improve durability and simplify routine cleaning and maintenance programs.

Green Building and LEED-Certified Projects

Projects pursuing LEED v4.x, LEED v5, CALGreen, WELL v2, Living Building Challenge, or Fitwel certification can use Consolideck LS with confidence, supported by a full suite of product transparency and compliance documentation.

Application Instructions

Surface Preparation

1. Ensure the concrete surface is clean, free of curing compounds, coatings, bond breakers, oils, or other contaminants that may inhibit penetration.
2. Confirm the concrete finish type is compatible: broom-finished, steel-trowelled, power-trowelled, or burnished concrete.
3. Refer to the Product Data Sheet for surface condition requirements specific to your project.

Application

1. Apply Consolideck LS at a rate of 500–1,000 sq ft per gallon, depending on surface porosity and absorption. Refer to the Product Data Sheet for specific coverage rates for your surface type.
2. Apply evenly to the concrete surface using appropriate application equipment. No scrubbing is required.
3. Allow the product to penetrate and react with the concrete substrate.
4. No flushing is required after application. No caustic wastewater is generated.

Post-Application

1. Allow the treated surface to cure fully before subjecting it to traffic or additional floor treatment steps.
2. Refer to the Product Data Sheet for specific cure times and any additional guidance for your application scenario.
3. Consolideck LS may be followed by compatible Consolideck guard and sealer products as part of a complete flooring system.
