Customer Questions & Answers

Can I use this as a concrete bonding adhesive for new over old concrete? I have some leftover from a level job.

Instead of buying another brands concrete bonding adhesive for a small job, can this be used to adhere new concrete over old concrete?
Asked by: steve
Howdy Steve, Concrete Leveler Primer (CLP) is a concentrated, solvent-free acrylic primer that improves the adhesion of Rapid Set Concrete Leveler to properly prepared concrete. CLP also acts to seal porous concrete surfaces to prevent pinholes and bubbles from forming in the finished surface. SUBSTRATE PREPARATION CLP is for use on properly prepared dry and porous concrete surfaces only. Substrate must be clean, sound, and free of oil, curing compounds, dust, mastic and other bond breakers. Mechanically profile surface by shot blasting or grinding. Acid etching the concrete surface is not recommended. As long as you properly prepared this could work for you. Happy bonding, Coach Dave

Will works as a concrete sealer on top of the concrete leveler

Asked by: Stricklc
This is not a sealer, if is a primer to make the concrete leveler adhere better to the underlying surface. Almost the opposite of a sealer, I would not put this on top. I would, however, use it as instructed or you chance the concrete leveler cracking.

using primer for thinset application?

Hello, I just finished leveling a bath and used the primer on all the floor prior to pouring. There is a small 2'x5' portion of the floor that did not get the leveling. Can thinset and tile be applied over this primer days later, or would I need another product to go over the primer? Maybe a new primer coat less than 24 hours before installing the tile with thinset? Thanks
Asked by: Moderntool
You can use thin set directly over our primer without any issues. Thank you for choosing Rapid Set!!

Bonding agent?

Hello, is this primer basically a bonding agent similar to a thin membrane? I need to level a bathroom that was previously covered in tile and installed with mastic. I have nearly removed it all except for very thin areas layers that are tight to the surface. Not in the mood to grind the whole floor. Will this stuff bond OK? Thanks
Asked by: Moderntool
Our Rapid Set primer is used to seal off the porosity in the existing slab and give you a nice sheen surface for the leveler to glide across when installed. We highly recommend getting as much of the mastic as possible up prior to installing for bonding purposes. Thanks you for choosing Rapid Set!

Customer Reviews

1 qt. Concrete Leveler Primer is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from Seems to work well, and I've seen what not using primer can lead to I've used this on floors where the previous leveler had to be completely removed because it never stuck to the floor and was crumbling under the flooring installed above it. I haven't had any problems with application or adhesion of leveler after using this primer. Spend a little more money up front and get the primer to save yourself a huge headache and expense later.

Rated 5 out of 5 by from 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.
