Sikaflex Self Leveling Sealant, Gray, polyurethane with an accelerated curing capacity for sealing horizontal expansion joints in concrete, 10.1 fl. oz Cartridge

This stuff is just great! You need to fill large gaps with backer hose otherwise it will take a lot of this to fill the joints. It is easy to use and does actually self level which I love as you don't have to get your hands messy trying to spread it, it spreads itself. I've used on all my joints around my pool deck which I now plan to paint with concrete paint. It's an added value that this is paintable.

I had a crack around my pool between the coping and the concrete decking . This stuff is very self leveling .Use a filler such as sand to fill the crack up to within a 1/4 of an inch from the top . I recommend using a fine sand to put on top after you apply a small area . This helps with the as the aesthetics of the finished job . I used some blue masking tape on the coping to keep it looking neat because this stuff can get messy . Do small lengths at a time , maybe 8 feet . This product works and stays flexible and does the job it was intended to do . Highly recommend .

MY project is a aggregate poured porch slab with brick surround. the bricks are pulling away from the slab that lets rainwater penetrate. These surfaces are uneven so the self leveling property is great. Even if your crack is quite narrow you WILL need to stuff the crack. This comes out of the tube quite runny and is for horizontal surfaces only. I have included a picture of a crack that was quite narrow and it still ran right through. I found out that pipe cleaners worked very well for the size cracks I had , the wire in the pipe cleaner was great to hold itself in the uneven cracks and I used flat bladed screw driver to force it below the finished surface. Afterwards the Sikaflex flowed on great with no sinking in and will look great after curing. As a sidenote, for my application I am getting about 40 lineal feet of coverage out of the LARGE tube.

The product itself is good, but one tube came broken and was unuseable. All four tubes were the wrong color. Instead of gray, which was ordered and on the label, the Sikaflex was beige. I didn't inspect the package carefully until the handyman came to install the product. But by then, 30 days had passed. Inspect your package as soon as it arrives. I will order again but this time, I will make sure the color is gray and the tubes are not damaged.

Had trouble with humidity creating a very slippery concrete floor in my garage when the humidity goes way up. The moisture would enter through the stress risers in the floor because they were cracked. Used this stuff and no more issues. Seals nicely and levels out on it's own, just don't try to overwork it. Clean the grooves in your floor, use a good caulking gun, cut the tip for a healthy bead, move slow and evenly and let the sealant level itself, try not to touch it. it dries to the touch over night.

Great productGood pricePay attention to proper handling and clean up

Great product applied easy and I love how it self levels. I feel this product is more durable the similar products and is a good value for the money.

Seems as though the first tube had some issues, which made me have to cut it open and make a big mess to get the substance out but the second tube seems fine. The stuff flows well once it's out and does self level pretty well.
