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.
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.
I just sealed my back patio due to expansion joints that were expanding. Based on the product descriptions of "elasticity" and all the stellar reviews, I figured this product would be perfect. After only one month this product had failed to stretch with the movement of the joint. Even the other joints I sealed showed the product separating from one of the spanned surfaces. Now the backing rod and sealant all have to be removed and the job has to be completed again with a better product. My office maintenance folks recommended "big stretch" caulking which appears to hold up great on our campus.

We are sorry to hear this. It is important to follow the product installation recommendations and ensure that the joint is within the product's maximum limitations to achieve a long lasting application.

It's a great product. It's very important that you prep the area first. Use backer rod to fill in big gaps, otherwise you waste too much sealant. I would give it 5 stars, but I think it's an over priced item.

Great product!! Used spray foam and trimmed excess instead of using backer rod for prep work. Downside is the product has an expiration date. Home Depot has a couple cases of near expiring product on the shelf. Found several tubes of a year or more on them and purchased those.
