Crack-Weld: Fix Cracked Concrete

This is our Original Crack Weld Filler, slow curing

When you work with concrete, you’re guaranteed to come into contact with cracked and damaged concrete. Cracks can be particularly frustrating for professional concrete floor coating installers. Cracks not only damage the integrity and appearance of concrete — they also damage the integrity of any overlay flooring installed on top of concrete. As an installer, that means you need to repair cracked concrete surfaces before any job can proceed. And you need to do it to the best of your ability — otherwise, you could create serious delays in your project.

Crack-Weld epoxy from Garage Coatings.com solves all of these problems. With Crack-Weld, you can fix cracked concrete, creating an ultra-strong bond between the two sides of any crack. Just as importantly it is a solvent-free formula means that you won’t need to delay or disable other parts of your installation.

Crack-Weld is a two-component epoxy that can be used to fix cracked concrete in practically any setting, on practically any job.

 Simply mix the A formula and B formula together, apply and spread the mixture, and wait. In five short minutes, the epoxy will penetrate into the crack, wick into the concrete. It will potentially seep through the crack itself to the bottom of the crack. As the Regular Crack Weld is not a paste but rather a typical heavy 100% Solids Epoxy Mixture. The use of silica sand ( 20 grit ) into the crack will help Dam the crack and not allow the Epoxy to run through the bottom of the crack. Repeat the process and over fill the crack so no low spots show. You can use a putty knife to smooth out the finish or grind the Epoxy down flush, after it has cure. Dry time will be 12-14 hrs  Approx.. depending upon Temperatures. We also offer the 5 Min Crack Weld if time is of importance. 5 Min Crack Weld is a paste patching compound used for Ultra Fast turnaround patching repairs. It is dry and cured in 20 min.
