## Description

Concrete Crack Filler is a ready-to-use epoxy sealer that makes quick and easy waterproof repairs to small cracks, holes, and seams in concrete and cement steps, patios, and garage floors. Buff-colored material cures to a color that blends in well. Concrete Crack Filler also fixes small cracks in brick, mortar, and slate. It comes in a handy cartridge that fits any standard caulk gun (with a recommended minimum 8:1 ratio). Just pop the cartridge into the gun, attach the included mixing tip to the cartridge, point, pull the handle and you’re ready to go.RTG Concrete Crack Filler is sag resistant so it won’t drip out of cracks and seams, and it begins to cure in minutes. Minimum recommended application temperature of air and substrate is 55°F or warmer. Gel Time: 10 minutes @ 72°F. Sandable: 3-4 hours. Tensile Strength: 8,500 psi. Compressive Strength: 9,600 psi. Flexural Strength: is 8,800 psi. RTG Concrete Crack Filler will not prevent or stop cracks caused by structural issues. *IMPORTANT: Exterior repairs must be painted over. Compare to Quikrete Concrete Crack Seal: RTG is easier to use, will not sag or drip when applied, and is easier to clean up. Compare to DAP Concrete Watertight Filler and Sealant; RTG Concrete Crack Filler is epoxy-based so it’s stronger, more durable, longer lasting, and more value. 100% made in the USA.

Review: Best stuff you can buy - I was unbelievably picky in selecting this product. This product did everything I needed it too. Pretty easy to apply and filled the cracks nicely. I used a utility knife blade while the product was still uncured to level it. Virtually no smell and hardened nicely.
Review: Product may work but not worth effort - The product was okay, it hardens nicely and looks okay but it was nearly impossible to get the product out of the caulking gun. It was way too much effort.

## Questions & Answers

**Q: What color does it dry to?**
A: A milky clear cokor

**Q: Does this work for sealing around a PVC sleeve through concrete?**
A: I would imagine you could use this for that. I used it on a flat concrete surface and it worked just fine. it's a two-part epoxy and the tip swirls eack part mixing it as it comes out of the tip.

**Q: I have a concrete fountain that has a crack/leak. Will this product be waterproof once cured?**
A: generally yes, but it does depend on the size of the crack and the preparation of the crack before application. You also need a good caulking gun because the product mixes in the nozzle and without a quality gun it will be hard to mix and apply.

**Q: Does this color match aggregate concrete?**
A: The filler is clear when it dries. You can easily part my over as we did in our basement and garage. It is highly concentrated and only cover a small difficult area. So make sure you plan ahead of applying it.

The product was okay, it hardens nicely and looks okay but it was nearly impossible to get the product out of the caulking gun. It was way too much effort.

### ⭐⭐⭐⭐⭐ Filling Workshop Floor Cracks
*by W***R on September 6, 2017*

After being irritated for years by a long thin hairline crack in my workshop floor, I decided to do something about because I eventually plan on painting over it with an epoxy floor paint. This product had a fairly thin consistency that made it easy to fill the crack without making a mess or wasting too much product. The crack is completely filled now, and you won’t even know it’s there once it get painted over
