Don't waste your money. It's runs out of the tube like water. I purchased another kind to use on my camper. It's more expensive but works.

This sealant applies very easily. I used 12 tubes and only had 1 tube that the beginning was a little off on the color. Set up time is minimal. It has been down for 3-4 weeks and looks great. The self-leveling is awesome. I used a tube every 12-15 feet. Very happy with product overall.

Easy application and great color
This is referred to as “the golden standard” for this type of product and I agree. It flows smoothly and dries looking like concrete. My local Hone Depot was out of stock and I needed more, so I went with Loctite. Not bad, but see my picture for the color difference. I will be ordering Sikaflex and removing the Loctite “Concrete Gray”. It’s far too glossy to resemble concrete.

    Tip for clean application
    Awesome product. I was so tired of my expansion cracks filling with sawdust, dirt, screws, etc. Best tip I found online was to put blue tape over the crack, cut along the edges, pull out the middle piece, and fill. After it tries you pull up the outside edges and presto - clean edge and no cleanup.

      Chose this type over the SL type because it can be applied to un-cured concrete. Difficult to apply perfectly flush with the surface, but easy to trim with a razor blade after it cures. Provides a hard, durable seal.

      I have bought over 1k in this product The issues that I’m having is some of the tubes have dried out and I’m not getting what I paid for. Also I had a full case of 12 tubes that would not cure properly. I had a heck of a time cleaning that mess up and replacing it with new sealer. The product is not getting rotated as per what the manufacturer asked Home Depot to do.

      Preparation is key. Up to 5 of use did this at any one time. We used masking tape for rough surfaces to line the cracks so control overflow and get a crisp finish. I made sure to sweep first so it would stick, and then followed with shop vacuuming the cracks. A person used a small paint brush to smooth down the Silka once squeezed in. A full 24 hours later I removed the taped and this is the finished. It's been a month and the weights of the many cars's tires have pushed the sealant into place and it's now it's own shade of gray. The is exactly the result I wanted. Using any other product that requires you to spray and set was a no go for me.
