Some are half dry in the tube
Bought 12 tubes, 3 where half dryed up, which pushes the liquid back into the gun. What a mess! The other 9 worked great, but I was short on my project and couldn't finish.

    Great for gaps between home foundation and concrete patio.
    I used this stuff to fill gaps between the home foundation and the concrete patio as scorpions likes to hangout in those gaps here in Arizona, the gaps were 2 inches wide and around 6 inches deep. I used sand as filler because the gaps were too deep after cleaning up the old material that was already there. Although I bought backer rod but I skipped using it because the area was wider and I wasn't sure if the backer rod will stay in place. It's been couple days and I'm happy with the results so far. Will do more of the other home sections in the soon future.

      Works very well
      It does what its supposed to do, but not the easiest to work with. Watch some videos and have a plan if using for the first time.

      Really nice product
      I really like this stuff. I filled the cracks with sand except for the top half inch and filled with this stuff.

      Exploded Tube - Quality Control?
      Bought two tubes to seal joints in freshly skimmed driveway. Used one with decent results than loaded the second tube. Per instructions I cut the nozzle, punctured the upper inside seal, loaded it into the caulk gun and pulled the caulk gun handle to start. The tube made a gurgling sound and the stuff shot out of the caulking gun relief holes. Caulk went everywhere. Whatta mess! All over my freshly skimmed driveway! Tried to wipe it up but now I have smeared caulk all over the driveway, not to mention the ruined caulk gun. To say I am displeased is an understatement. However and to be fair - this is my second application of Sika on my driveway. The first application ultimately developed cracks and splits after a few years under oppressive TX summer heat. But I figured I would give it another shot. The sealant is a decent product but the packaging needs some quality control attention.

        Believe me. Will blow out at bottom.
        Even though I punctured good size hole, three out of four tubes blew out at the bottom. Big mess. Ruined gun and driveway. I don’t recommend this brand. Buy Loctite. Similar application with lower price.

          easy to apply, high quality and looks really nice.
          You can use a chaser blade on an angle grinder to wider some cracks and make them look more even first (see 3rd photo), otherwise for normal spacing gaps in concrete it is super easy. Clean out the cracks to be concrete only, no dirt/etc. Use backer rod that is wider (1/4") bigger than the gaps you fill. Leave at least 1/4" but no more than 1/2" space between top of concrete and backer rod. The ratio you want is 2:1 width to depth ratio, and ideally no wider than 1" though i've gone a little wider than that in a couple places and it was fine. And then simply use caulking gun to fill in the gaps. Have paper towels on hand, ideally someone to hold them when you need them. Solvent based stains or paints can't be applied on top of this, but water based ones can.
