Questions & Answers

Do i have to delude it

Answer This Question

For excessively porous or absorbent concrete surfaces, multiple coats may be necessary. Prime the surface with an initial application of diluted primer at a ratio of 1 part water to 1 part primer. Allow to dry and become tack free. Then, apply a second coat of undiluted primer. Repeat as necessary until the final coat of primer stays wet for at least 20 minutes. Lower temperatures and/or higher humidity will extend drying time.

    How much primer do I need to treat 50 square feet?

    Answer This Question

    This would depend on how porous your substrate is. One quart covers about 50 ft2 to 100 ft2 and one gallon covers about 200 ft2 to 400 ft2.

          Will this work on sanded terrazzo?

          Answer This Question

          Our concrete leveler cannot be used over sand stone. So there is no need for the primer if that is your question.

            No seal on 1 gallon bottle. Most concrete primers (if not all others) have a seal under the cap. This is much thinner than expected and wanted to assure I did not just purchase a returned bottle that was watered down. Please let me know.

            Answer This Question

            Yes our primes should have a sealant under the cap. I would exchange it for a new one.

              Can this be used to prime Masonry such as brick or cinder block before pouring traditional concrete or self leveling product or applying screed to enhance bonding?

              Answer This Question

              It wont enhance bonding like bonding adhesive would. It used to help seal poures to stop moisture wicking.

                Answer This Question

                Apply Concrete Leveler after the primer is dry (usually 30 minutes to 3 hours) and within 24 hours of the final primer coat. If more than 24 hours have elapsed, reapply primer.

                  So far, the primer has successfully adhered the concrete leveler. I just finished the project last week, so not a long test yet.

                  In my previous life, pre-retirement, my business card said, "We don't do concrete, or roofs". Now, in this life, I NEED to level off my patio so the water won't create a pond. We are planning on getting this hired out, but, in my search of the perfect how's and why's of concrete work, this leveler primer keeps showing up as a must do. It does for concrete what primer will do for a painting project. ANYTHING to make this a one time event in my life is a good thing. It creates a "BOND" between the old concrete (mine is now 26 years old) and the new wet slurry mixture. No action packed pictures yet.

                  The RapisSet Concrete Leveler Primer is a great acrylic primer to use with a concrete leveler. It's sticky and will improve the adhesion of the concrete leveler to the existing concrete. It's meant to be used above 50 degrees Fahrenheit for best adhesion and it's recommended to mix one part primer with one part water. It needs to be applied to a clean, oil free surface and worked into the surface so the leveler will adhere properly. Multiple coats can be applied with sufficient drying time in between. It's a quality product to help seal porous concrete.

                  Use before the concrete leveler for adhesion
                  I ordered a bag of concrete leveler and this primer because the recommendation for using the leveler is to apply the primer first. Follow the directions printed on the side and allow ample drying time for the primer and you shouldn't have any problems with the leveler or your finished project. I did a small vestibule area first and used a paint brush from the dollar store to apply the primer. I am preparing the area for tile and it needed to be repaired and smoothed over.
