Perfect for decking around pools
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 .

Perfect if used correctly...self leveling..STUFF your cracks!!
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.

Filled My Stress Risers
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.

Product is good, Color was wrong and one tube was damaged
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.

This is the real deal
After trying a cheaper product that never really set up, I cut out the failed product and used this. AMAZING difference. This product will self level, sets up in 24 to 36 hours in direct sunlight (hot temps) and leaves a firm, gray rubber like finish. This is my go-to product for all future driveway crack repairs. So glad Amazon carries this brand! The 29 oz tubes showed up in good condition and was a breeze to apply except for difficulty squeezing the caulk gun handle on the last 1/2 of the tube. I used 2" masking tape to mask off the crack for a tidy looking finished job. I first cleaned out the crack, filled half way with sand, then backer rod, then crack filler. I slit down a pool noodle for backer rod material. Warning; when you let off the gun handle and release pressure, the product will continue to ooze out the tip so have something ready to catch the drool so your project looks professional when completed. Moving forward I will always choose this product and highly recommend it. This stuff makes me look like I know what I'm doing ;)
