Pourla® High-Performance Epoxy Primer
What is a High Performance Epoxy Primer?
Pourla® High-Performance Epoxy Primer is a two-component resin-based formulation engineered to create a firm, vapor-resistant membrane that meets the stringent requirements of ASTM D4541-22 for adhesion strength and ASTM E96 for water vapor transmission (SPECIFICATIONS). The system forms a continuous, impermeable film over concrete substrates, delivering superior adhesion and long-term moisture protection.
As the foundation layer of any professional epoxy flooring system, this clear penetrating primer bonds deeply into the concrete surface to reinforce substrate integrity and establish a strong mechanical bond for subsequent coatings. Its verified performance as a moisture barrier (per ASTM E96) effectively prevents issues such as bubbling, delamination, and cracking—common failures in unprimed or inadequately sealed floors.
Unlike traditional opaque gray primers, Pourla’s crystal-clear finish preserves the natural aesthetic of marble, terrazzo, or decorative concrete while providing industrial-grade protection. This allows designers and installers to achieve both transparency and durability in a single product.
Functioning simultaneously as a primer, base coat, and vapor barrier, Pourla® High-Performance Epoxy Primer locks out moisture, strengthens weak or porous areas, and ensures optimal adhesion for metallic, flake, or pigmented epoxy layers applied above. The result is a seamless, high-gloss surface built to perform and last.
Key Features of Our Epoxy Primer
Every flooring project needs a strong foundation and that’s where this primer stands out. It combines durability with design freedom, giving you protection, flexibility and a clear finish for professional looking results.
Clear Finish Option
This epoxy primer stays transparent, keeping the natural look of marble or polished concrete. Unlike gray primers, it works as a clear epoxy sealer that enhances design freedom.
Moisture Sealing and Vapor Barrier
It creates a moisture barrier epoxy layer that blocks vapor from rising through concrete. This stops future damage and protects floors from peeling, cracking or delamination.
Deep Concrete Penetration
The solid formula penetrates concrete surfaces, increasing adhesion between the primer and top coats. Strong epoxy adhesion ensures your flooring system lasts longer and resists wear.
Flexible Tinting Option
Use it clear for decorative surfaces or add pigment additives for a custom look. This flexibility makes it suitable for both modern homes and commercial spaces.
Fast Cure and Easy Recoat
The industrial grade system cures quickly with recoating possible within hours. Its reliable performance saves time for contractors and DIY users working on tight schedules.
Low VOC and Easy Mixing
The 2-part epoxy primer is VOC-free. It is easy to prepare and can be used safely indoors. With a simple 2:1 mixing ratio, it delivers consistent results for any flooring project.

How to Apply Epoxy Primer Correctly?
To get the beautiful floor, you need to start with the correct preparation and application. Just follow these steps:
Step 1: Prepare the Surface
The first step is to clean the concrete or plywood subfloor very carefully. Remove dust, oil or old coatings. Grinding or shot blasting is recommended for stronger adhesion and smooth epoxy floor preparation.
Step 2: Mix the Primer
Combine two parts resin with one part hardener by volume. Stir for at least three minutes until blended. Remember don’t create air bubbles during epoxy primer mixing.
Step 3: Apply the Primer
Pour the mixed primer in ribbons across the surface. Spread evenly using a squeegee then back-roll with a microfiber roller for a smooth epoxy coating finish.
Step 4: Allow Proper Cure Time
The primer begins curing in 5–6 hours at 77°F. Floors reach full cure within 36–48 hours under normal conditions. Keep the area free of traffic until fully hardened.
Step 5: Follow Pro Tips
Wear spike shoes to move across the wet surface without marks. Clean with 91% isopropyl alcohol instead of acetone for better adhesion between layers.

Technical Specifications
- Color: Clear Light Blue
- Density: Epoxy Resin(66.8 ± 3.1 lb/ft³) Epoxy Hardener(61.2 ± 1.9 lb/ft³)
- Resin Viscosity: 800cP @ 77°F
- Hardener Viscosity: 60 cP @ 77°F
- Mix Ratio by Weight: 2A:1B (2 part resin to 1 part hardener)
- Coverage: 150-200 ft²/gallon
- Recommended Working Temperature: 65–75°F
- Working Time: 25 ± 5 minutes at @77°F
- Initial Cure Time: 5-6 hours @77°F
- Full Cure Time: 36-48 hours @77°F
Work Environment
- Keep the adhesive containers clean. Mix components A and B strictly according to the specified ratio. Accurately measure the components, stir thoroughly along the inner wall of the container in a clockwise direction until evenly mixed, and let the mixture sit for 3-5 minutes before use.
Precautions
- Adjust the amount of adhesive mixed according to the operational time and required usage to avoid waste. When the temperature is below 60°F, preheat component A to 86°F before mixing to ensure easier handling (as component A thickens in lower temperatures). After use, seal the container lid tightly to prevent moisture absorption, which could render the product unusable. When the relative humidity exceeds 85%, the cured material surface may absorb moisture from the air, forming a white fog-like layer.
