CPRL UK is a supplier of high-quality epoxy, polyurethane, and MMA paints and coatings1. Whether you’re working on a large-scale industrial project or a small home improvement job, understanding concrete primers is essential. Let’s dive in!

Concrete Primers

What Are Concrete Primers?

Concrete primers play a crucial role in preparing concrete surfaces before applying floor paints and coatings. They enhance adhesion, durability, and overall performance. At CPRL UK, we offer a range of concrete primers suitable for various applications:

Epoxy Concrete Primers: ist of pre-weighed BASE and CURING AGENT components. They work well with high-build epoxy floor paints and polyurethane resin-based paints. Some top-selling epoxy concrete primers include:

Acid-Resistant Primer: Used for protecting concrete or steel reinforcement in chemical environments. It pairs well with products like CPR 604 (Acid Resistant Epoxy Screed) and CPR 605 (Self-Sealing Acid Resistant Screed).

Sub-Zero Primer: Ideal for cold storage facilities, food processing plants, and outdoor environments with extremely low temperatures. It allows you to prime and paint cold rooms and freezers without adjusting the ambient temperature2.

Water-Based Epoxy Primer: Environmentally friendly and solvent-free, making it suitable for sensitive operating environments like kitchens and laboratories. It can be used as a stand-alone protective coating or in conjunction with other paints and coatings.

MMA Concrete Primers: Methyl methacrylate (MMA) primers are quick-drying and suitable for porous surfaces that transfer moisture easily. They enhance UV resistance, abrasion resistance, and overall strength. These primers are perfect for quick return-to-service applications, even at low temperatures.

Surface Tolerant Primers: Designed for harsh environments where moisture, corrosion, or humidity are issues. They provide excellent adhesion even on imperfect surfaces.

Choosing the Right Primer

When selecting a concrete primer, consider factors such as the project type, surface conditions, and desired performance. At CPRL UK, we’re here to help you find the perfect primer for your specific needs. Whether you’re painting a factory floor or improving your garage, our range of concrete primers has got you covered.

Tips for applying concrete primers

Surface Preparation:

Clean the concrete surface thoroughly by removing dust, dirt, oil, and any loose particles. Use a broom, vacuum, or pressure washer.
Repair any cracks, holes, or uneven areas. Fill them with an appropriate patching compound and allow it to cure.

Choose the Right Primer:

Select the primer based on the type of concrete (new or existing), the coating system you plan to use, and the environmental conditions.
Consult the manufacturer’s guidelines to determine the best primer for your specific project.

Mixing and Application:

Follow the mixing instructions carefully. Some primers are two-component systems that require precise ratios.
Use a roller, brush, or sprayer to apply the primer evenly. Pay attention to corners, edges, and seams.
Apply the primer in thin coats to avoid puddling or excessive buildup.

Coverage and Drying Time:

Achieve the recommended coverage rate specified by the manufacturer. Too little primer may result in poor adhesion, while too much can lead to surface defects.
Allow the primer to dry completely before applying the topcoat. Drying times vary based on the product and environmental conditions.

Temperature and Humidity:

Apply primers within the recommended temperature range. Cold temperatures can slow down curing, while high temperatures may cause premature drying.
Avoid applying primers in extreme humidity, as it can affect adhesion and drying.

Ventilation and Safety:

Work in a well-ventilated area to prevent inhaling fumes.
Wear appropriate personal protective equipment (PPE), including gloves, goggles, and a mask.

Testing Adhesion:

Before proceeding with the topcoat, perform an adhesion test. Apply a small area of the coating system and check if it adheres properly.
If adhesion is poor, address any issues before continuing.

Conclusion

Concrete primers are the foundation for successful floor coatings. Choose wisely, and your project will benefit from improved adhesion, durability, and longevity. For more information on our concrete primers, feel free to contact us.
