Control Joints and Nohr-S question (Colorado)

[charliecafe]

Hey everyone! Very new to the forum and have been getting some great information/ideas for coating the garage floor on a house that I close on next week.

I've pretty much decide to go with the Nohr-S product partly due to wanting to get the floor done before we move in while nothing is in the garage and due to the 35-60 degree temps during this time. We're giving ourselves 4-5 weeks to get some remodel stuff done while the home is empty, but chances of temps holding high enough for a few days to do Epoxy are unlikely.

Anyway, one of my main issues I can't decide on is filling the control joints for a seamless floor. Since Colorado is of course known for swelling soil, I'm wondering if anyone on here from Colorado has any experience with filling the joints prior to coating and then having cracks transition back through the surface? The house is 27 years old, a couple of the joints have 1/4 cracks down them, no apparent heaving, and no other cracks across the individual pads.

I'm hung up between taking the chance on filling prior to coating and dealing with coating repair later if the cracks come back through due to movement, or just using a flexible compound after the coating for keeping debris out of the joints.

Thanks for any help and suggestions that you have!

Legacy sells great product. I highly suggest you talk to Scotty directly about looking to do what you want to do.

In general: If there is not an overwhelming reason to fill saw cuts or joints, I don't. Its a Ford Chevy argument. My personal opinion is if you are doing it for the seamless look, go for it. BUT be prepared to take your time and make sure those joints are perfect or you will see them through most coatings.

If its a cleaning issue. Sikaflex after the fact.

If you decide to fill them pre-coat, Scotty has a very very good Polyurea based filler. TALK to him about it and the best ways to get it perfectly level

Thanks for that feedback!
The main is to keep debris out because it drives me nuts so I figured why not go with the seamless look since I'm doing the work. However, I had not thought about getting those joints perfectly flat and smooth with the filler component so that they don't show through the surface. That's a really helpful comment and to add into the cons column keeping me leaning to filling after.
Sikaflex is actually what I was thinking of using after the coating. I know it won't be a perfect match, but it will be functional for keeping a "clean" floor with debris out of the joints. Funny I used to work summers for Sika in Santa Fe Springs, CA during college as an installer for their concrete admixture systems on concrete plants, so I know they make some good materials.

Thanks again!

Glad to help. I cant emphasize enough, talk to Scotty and run all of this buy him. He knows his product very very well

You can coat the floor and go back later wth the SIKA.
Do not want to put coatings over it. It is too flexible for that.

Good luck!
