SLABLOC® 150 is a two-component, 100 percent solids epoxy engineered for high-performance moisture-mitigation systems. Contractors apply it beneath resinous flooring systems or floor coverings in commercial and industrial concrete slabs to control elevated vapor emission rates. This formulation provides professional applicators and facility teams with a reliable, low-permeance barrier to protect sensitive topcoats.
Professional concrete flooring contractors rely on SLABLOC® 150 to condition substrates prior to applying topcoats. It’s commonly specified for interior concrete slabs exhibiting high internal relative humidity or elevated alkalinity. Typical environments include:
SLABLOC® 150 functions as a substrate conditioning and moisture control layer. It isn’t intended as a finished floor or exposed wear surface. Installers must cover this product with an approved SLABHARD® flooring system, cementitious underlayment or resinous topping. It enables successful installation of epoxy flooring systems in environments where moisture conditions would otherwise cause bond failure. Applicators must adhere strictly to the specified cure and recoat windows.
Contractors must mechanically prepare concrete substrates to an ICRI CSP 2 to 3 profile. Acid etching is strictly prohibited. Applicators must remove all surface contaminants completely prior to application to ensure proper adhesion. Substrate and ambient temperatures must fall between 50 and 90 degrees Fahrenheit and remain a minimum of five degrees above the dew point. Concrete can be damp during application but must remain free of standing water. Mix the two components thoroughly and pour the material immediately to maintain working time. High humidity and low temperatures will extend the cure time.
Can SLABLOC® 150 be used as a final wear surface?
No. It’s engineered strictly as a moisture vapor barrier beneath resinous flooring systems and requires an approved topcoat.
What are the required concrete surface preparation standards?
Substrates require mechanical preparation to an ICRI CSP 2 to 3 profile. Acid etching isn’t permitted.
Does this product meet ASTM F3010 requirements?
Yes. It exceeds performance requirements for two-component moisture-mitigation systems.
What types of topcoats are compatible with this product?
Contractors can apply moisture-sensitive floor coverings, cementitious underlayments and approved SLABHARD® resinous coatings over this layer.
How long is the working time for the regular cure version?
The regular cure formulation provides a 20 to 30 minute pot life at 73 degrees Fahrenheit.
Does this material handle high alkalinity?
Yes. It is engineered to perform reliably under sustained high-pH conditions in new and existing concrete slabs.

SLABKRETE™ UC Topcoat is a three‑component urethane cement topcoat engineered exclusively for urethane cement flooring systems. Designed as the final performance layer within SLABKRETE™ 100 FS installations, it seals broadcast aggregate, refines surface texture, and enhances long‑term durability, chemical resistance, and cleanability in demanding industrial and commercial environments.
Applied as a thin‑film seal coat, mid‑coat, or aggregate encapsulation layer (depending on system design), SLABKRETE™ UC Topcoat delivers strong adhesion to cured urethane cement and supports aggressive sanitation and wash‑down procedures. This low‑odor, low‑VOC formulation is suitable for occupied or sensitive facilities when installed under proper ventilation.
Ideal for urethane cement flooring systems installed in:
Color System
Color is carried through Part B.
Typical Coverage Ranges
Is SLABKRETE™ UC Topcoat a standalone coating?
No. It is designed exclusively as a topcoat within urethane cement systems.
What problem does it solve?
It seals broadcast aggregate, improves cleanability, refines surface texture, and enhances chemical and abrasion resistance.
Can it be used as a mid‑coat or seal coat?
Yes. It may function as a mid‑coat, topcoat, or aggregate encapsulation layer depending on system design.
Is it UV stable?
No. Yellowing may occur with UV exposure; this is cosmetic only and does not affect performance.
Where does the color come from?
Color is carried through the Part B component of the system.
What environments is it best suited for?
Industrial and commercial environments with chemical exposure, sanitation requirements, impact, and abrasion—such as food processing, commercial kitchens, labs, and manufacturing areas.
SLABKRETE™ 100 FS is a fast-setting, heavy-duty urethane cement flooring product engineered for industrial and commercial environments where thermal shock, chemical exposure, and heavy traffic are everyday challenges. Applied at 3/16″–1/4″, this flowable slurry delivers rapid return-to-service, strong adhesion to concrete, and long-term durability. Its flowable consistency ensures even coverage across properly prepared substrates, with an optional aggregate broadcast for slip-resistant performance.
Ideal for industrial concrete coatings and commercial flooring applications, including:

Extended lead times are required for fulfillment. Color samples and printed representations are for general reference only. Actual results may vary based on substrate conditions, application techniques, environmental factors, and display or printing limitations. For precise color matching, always confirm using an approved sample under actual jobsite conditions.
Is SLABKRETE™ 100 FS a urethane cement product?
Yes. It is a urethane cement flooring product formulated for high-demand industrial and commercial environments requiring thermal-shock and chemical resistance.
Can it be topcoated?
Yes. SLABKRETE™ 100 FS is compatible with multiple SLABHARD® topcoats, including polyaspartic and urethane formulations.
Does it require a primer?
A primer is recommended. Use an approved SLABHARD® primer to ensure optimal adhesion and durability.
Can installers broadcast aggregate?
Yes. Quartz or aluminum oxide may be broadcast for slip-resistant texture or to enhance traction.
What environments is it best suited for?
Facilities with sanitation requirements, temperature swings, or heavy traffic—such as food processing, commercial kitchens, cold storage, and chemical-processing areas.
