Acrylic Primer

If you’d like to simplify your TRU® Self Leveling projects, use Rapid Set® Acrylic Primer to improve the adhesion of TRU Self Leveling to properly prepared concrete. You can also seal porous concrete surfaces to prevent pinholes and bubbles from forming in the finished surface with Rapid Set Acrylic Primer. Available in 1-gallon jugs that cover about 400-600 square feet.

Standard Practices

Q: What is Rapid Set® Acrylic Primer and what can it be used for?
A:
Rapid Set® Acrylic Primer is a concentrated primer that improves the adhesion of self-leveling products and acts to seal porous concrete to prevent pinholes and bubbles from forming in the finished surface.

Q: How do I prepare the substrate prior to applying Acrylic Primer?
A: Mechanically prepare the substrate by shot-blasting and/or diamond grinding to achieve ICRI Concrete Surface Profile (CSP) 3. The substrate must be clean, sound, have an absorptive surface and be free of oil, concrete sealers, or any other material that may inhibit bond. Remove all shot, dirt and other debris.

Q: Do I need to dilute Acrylic Primer?
A: Yes. In most cases dilute with 1 part water to 1 part primer. For excessively porous or absorbent concrete surfaces, multiple coats may be necessary. Dilute the first coat with 3 parts water to 1 part primer. Additional coats should be diluted 1 part water to 1 part primer.

Q: How many coats are required?
A: It depends on the substrate. If the primer dries in less than 20 minutes, that is an indicator that the substrate is excessively porous. Additional coats may be added as soon as the previous coat is dry. Add additional coats until the primer stays wet for at least 20 minutes.

Q: How do I apply Acrylic Primer?
A: Apply primer to the substrate and work into the surface with a soft-bristle push broom. Spread evenly to thoroughly coat the surface and avoid puddling.

Q: What is the coverage of Acrylic Primer?
A: The coverage is dependent on the surface profile and absorption rate of the concrete. In most cases, 1 gallon of Acrylic Primer diluted with 1 gallon of water will cover 400 – 600 ft2

Q: How soon can I apply Rapid Set products over Acrylic Primer?
A: Allow the final coat of Acrylic Primer to dry for a minimum of 3 hours and maximum of 24 hours and confirm the primer is completely dry and there are no puddles prior to applying Rapid Set products.
