Epoxol Primer - Epoxy Adhesion and Concrete Sealer

Applying Epoxol Primer for Epoxy and Concrete Sealing

Substrate Preparation for Concrete and Cement Screed:

1. Allow the concrete to cure for at least 28 days, taking necessary maintenance measures during this period.
2. Mechanically prepare the cementitious substrate (e.g., grinding, shot blasting) to achieve a smooth surface and ensure optimal adhesion.
3. The surface should be dry, clean, and protected from rising moisture. Remove any loose or friable material by brushing or sanding with appropriate equipment and a high suction vacuum cleaner.
4. Strive for a smooth, flat, and continuous surface without voids or cracks. Use Epoxol Putty to fill in any cracks.

Application:

1. Mix the two components A and B in the predetermined ratio.
2. Stir the mixture for about 2-3 minutes using a low-speed electric stirrer until it becomes homogeneous.
3. Apply one layer of the mixture to the surface using a roller, brush, or airless spray.
4. For highly porous surfaces, consider applying an additional layer if needed.

Special Notes:

• Do not apply Epoxol Primer in wet conditions or if wet conditions are expected during the application or curing.
• Store the components in suitable temperatures, and mix and stir the mixture mechanically in the shade.
• Avoid over-stirring to prevent air entrapment in the mixture. Apply the mixture immediately to prevent it from hardening inside the container.
• Note that prolonged UV exposure may lead to chalking of the final coating over time.
• If more than 24-36 hours have passed between successive layers, lightly sand the previous layer to prevent potential adhesion issues with the next layer.

What is Epoxol Primer used for?

• Epoxol Primer is used to enhance adhesion for epoxy, polyurethane, or polyaspartic floor coatings and can also serve as a concrete sealer.

When can I apply Epoxol Primer on concrete?

• Concrete should cure for at least 28 days before applying Epoxol Primer. Make sure it's dry, clean, and free from rising moisture.

How do I prepare the concrete surface for the primer?

• Mechanically prepare the surface using methods like grinding or shot blasting to ensure it's smooth and conducive to adhesion. Remove loose material with appropriate equipment.

What should I do if there are cracks in the concrete?

• Fill cracks with Epoxol Putty to achieve a smooth, continuous surface without voids or cracks.

How do I mix and apply the primer?

• Mix components A and B in the predetermined ratio, stir for 2-3 minutes, and apply a single layer using a roller, brush, or airless spray.

Can I apply more than one layer of Epoxol Primer on highly porous surfaces?

• Yes, consider applying an additional layer if needed for highly porous surfaces.

What conditions should I avoid during application?

• Avoid applying in wet conditions or when wet conditions are expected during application or curing.

How should I store and handle the primer components?

• Store the components at suitable temperatures, mix and stir them mechanically in the shade, and avoid over-stirring to prevent air entrapment.

What should I be cautious about with prolonged UV exposure?

• Prolonged UV exposure may lead to chalking of the final coating over time.

Why is it important to lightly sand between successive layers?

• To prevent potential adhesion issues with the next layer, lightly sand the previous layer if more than 24-36 hours have passed between applications.

Is Epoxol Primer suitable for all types of floor coatings, including polyurea?

• Epoxol Primer is primarily designed to enhance adhesion for epoxy, polyurethane, and polyaspartic floor coatings. While it excels in these applications, its compatibility with polyurea may vary depending on specific formulations. It's recommended to conduct a compatibility test before using Epoxol Primer with polyurea to ensure optimal results. For polyurea-specific priming needs, it's advisable to consult with the manufacturer of the polyurea product.

Can I use Epoxol Primer on both absorbent and non-absorbent surfaces?

• Yes, Epoxol Primer is versatile and can be used on a variety of surfaces, whether they are absorbent or non-absorbent. It excels in providing excellent adhesion to different construction substrates, making it suitable for both porous and non-porous surfaces. However, it's important to ensure that the surface is properly prepared, as mentioned in the application instructions, to achieve optimal results. Proper surface preparation is crucial for the primer to bond effectively, regardless of substrate absorbency.
