LABPOX® PRIMER – 100% Solids Epoxy Concrete Primer

LABPOX® PRIMER by Lab Surface is a professional-grade, 100% solids, two-component epoxy primer designed to deliver superior adhesion, excellent concrete penetration, and reliable performance beneath resinous flooring systems.

Featuring an exceptionally low viscosity of approximately 300 cps, LABPOX PRIMER is engineered to penetrate properly prepared concrete surfaces, helping establish a strong bond between the substrate and subsequent epoxy coating layers.

Its proprietary Pinhole Mitigation Technology helps reduce pinholes caused by air escaping from porous concrete, minimizing surface imperfections and helping contractors achieve smoother, more consistent finishes.

Designed for residential, commercial, and industrial flooring applications, LABPOX PRIMER provides a combination of fast curing, excellent adhesion, and long-term durability, making it particularly valuable for heavy-duty and high-traffic environments.

Whether installing metallic epoxy floors, decorative flake systems, or industrial epoxy coatings, LABPOX PRIMER helps establish a reliable foundation for professional flooring installations.

Application Recommendations

1. Surface Preparation

Proper concrete surface preparation is essential for successful epoxy flooring installations.

Concrete must be structurally sound, clean, and free from dust, oil, grease, existing contaminants, and materials that could interfere with adhesion.

Mechanically prepare the surface using appropriate diamond grinding or shot blasting equipment to achieve the concrete surface profile (CSP) required by the coating manufacturer.

Repair cracks, joints, and surface imperfections as necessary before applying the primer.

2. Mixing

LABPOX PRIMER uses a 2:1 mixing ratio (Part A to Part B).

Measure and combine both components according to the manufacturer’s instructions.

Mix thoroughly using a low-speed mechanical mixer until a uniform consistency is achieved.

Avoid excessive mixing speeds that could introduce air into the material.

3. Application

Apply LABPOX PRIMER to properly prepared concrete using a compatible squeegee and roller.

Distribute the material evenly, allowing the low-viscosity formulation to penetrate the concrete surface.

Avoid excessive material buildup and puddling.

Porous concrete may require additional attention or a second application depending on substrate conditions and manufacturer recommendations.

4. Curing & Recoating

LABPOX PRIMER features fast-curing characteristics, with a reported curing time of approximately 2 hours and 30 minutes under specified conditions.

Actual curing and recoating times depend on temperature, humidity, substrate conditions, and application thickness.

Always follow the manufacturer’s recommended recoat windows before applying subsequent epoxy layers.

Why Contractors Choose LABPOX PRIMER

A successful epoxy flooring installation starts with proper concrete preparation and a reliable bond to the substrate.

LABPOX PRIMER is engineered to improve adhesion while helping minimize pinholes and other surface defects associated with porous concrete.

Its combination of ultra-low viscosity, fast curing, and pinhole mitigation technology makes it an excellent choice for professional contractors installing decorative and industrial resinous flooring systems.
