Review: You need double the amount if you really want flat topped joints - I am giving this 5 stars because it does exactly what they say and was a complete kit including mixing paddles and cups. Everything went according to direction. It is expensive and I was hesitant to buy 2 kits for my 3 car garage but I should have. If you are having second thoughts about buying more than you think you need, heed this warning. The hassle of removing everything from your garage (tools and other expensive, theft targets) and prepping everything and then doing the joint fill and flooring coating while that stuff is at risk of theft is a giant bucket of stress that is far more "expensive" than an extra kit!! Seriously, just buy the extra and if you don't use it send it back. I will make another recommendation that will help the install. Get foam core to partially fill the joints and get a caulking gun to run a bead on the bottom of the joint to glue down the foam core so the joint filler doesn't "float" the foam core up and leak under it. Every place I used caulking went well and where I thought the foam core was tight enough, it wasn't. Lessons learned for me. Other than that my project was successful. When this cures, it has a slightly rubbery feel like silicone but a lot firmer. So far my polycuramine floor coating is not cracking or showing any issues where the joints are.
Review: Happy with epoxy mixture with added sand - Worked pretty much as described. The only problem was after I added dry sand the propeller on the me ice furnished broke off. I mixed it with a putty knife and it worked great.

## Questions & Answers

**Q: Will this seal a hairline crack on a leaking cement above-garage patio?**
A: It certainly will. However, ElastiPoxy is quite thick. You should chase the crack to a depth of roughly 1/2inch and then pour the epoxy in. You should also take a look at our CrackWeld Concrete Floor Repair Kit. It uses a quick curing 2-component urethane that is very low in viscosity.  Perfect for hairline and thin cracks - no grinding or prep required.  Give us a call if you want to discuss further. Dan@RadonSeal

**Q: Can I use this if I am just getting seepage at the cove joint? There is no visible crack.**
A: Not sure what you want to seal if there is no crack, but the product is easy to apply.  I used a syringe and applied it to the crack between my basement wall and floor.

**Q: Can I grind it after curing?**
A: Yes, you can grind or sand it down smooth after the product has fully cured.

**Q: how much does 2 quarts cover?**
A: Based on a 1/4" wide x 1/2" deep control joint, ElastiPoxy® will fill 70 linear feet (without sand). Mixed with sand (4:1 ratio), ElastiPoxy® will fill 300+ linear feet of cracks.

### ⭐⭐ This product DOES SHRINK
*by D***N on August 26, 2025*

Product is a little tricky to work with. I found that syringes work the best in applying it cracks. After three months it did shrink and crack…. A lot. I have reapplied lately and now seeing what happens. I’m currently looking into other products due to the amount of cracking and shrinkage
