Red Devil RD 3000 Advanced Self-Leveling Concrete Sealant

Used this product to fill in seams in a garage floor. Overall it was easy to use and works well but a liitle pricey. It took a full two weeks to cure completely at an average thickness of 3/4" in most of the seams. The floor is much simpler to keep the chips and dust cleaned up from now and the floor jacks and carts roll without that dreaded sudden stopping at a seam.

This is the best material to fill voids in concrete and keep grass and debris out IMO. It self levels and dries to a concrete gray color, as claimed. It cost more, but is worth it IMO.

This stuff is the bomb! It's really like a thin silly putty in color and texture. But once it cures it stays hard but very flexible. Great sealer, and after filling all the cracks on the cement deck above the garage there was no more leaks or water intrusion after a long steady rain. To best apply this product you should heat the tube up before application. If you have a coffee mug warmer, standing on something like that for 15 - 30 mins prior to putting in the caulking gun will help tremendously. This is a pretty hearty sealant, so applying cold will not be impossible, but it will be more difficult w/o heating first.

While it does appear to seal the cracks, it's runny. One would expect it to be a heavier consistency being in a calking tube. It's almost impossible to use on a vertical surface. Time will tell if it's durable. Update: It's been on for three years and has held up well.

The color of product resembles of concrete. In 2 days, I was walking on the filled cracks of my concrete floor. The color of GE product is dark grey

Very competitively priced ($3-4 less per tube than a big box store). Like the feature of the removable spout, makes it easy to clean out and re-seal a partial tube. Product dispenses easily and dries quickly. Very happy with the product, packaging and price.

If you want everything to be black, hands, screws, tools, get this. It's a real mess. Takes way too long to cure.

I used this to seal the joints on my stamped concrete patio. I placed round backer foam in the joints before applying the caulk. It adheres to anything and levels out perfectly. I would definitely recommend using this product.

it does work

Item was found damaged after opening box . Leaking from crack in plastic container.

its not really self-levelling. you need a level or finger to level the caulk
