SIKA Sikaflex Self-Leveling Sealant, Sandstone, 29 fl oz

I’m very happy with this SIKA Sikaflex self-leveling polyurethane sealant. The product is easy to work with, spreads smoothly, and helps create a clean, professional-looking finish. It is a great option for sealing cracks and joints where a durable, reliable seal is needed. The self-leveling formula makes the application easier and helps the material settle evenly into place. The quality feels excellent, and it seems designed to provide long-lasting protection against water and the elements. Overall, this is a high-quality product that does the job well. I would definitely recommend it to anyone looking for a dependable sealant for home improvement or repair projects.

Professional-Quality Self-Leveling Sealant That Makes Concrete Repairs Easy I've used several products for sealing concrete joints over the years, and Sikaflex continues to be one of the brands I trust. This self-leveling polyurethane sealant flows nicely into horizontal expansion joints, creating a smooth, professional-looking finish without having to spend time tooling the surface by hand. The sealant adheres well to properly prepared concrete and cures into a flexible, waterproof joint that should hold up well to changing weather conditions. I also like that it can be painted after it has fully cured, making it easier to blend repairs into the surrounding concrete if desired. Application is straightforward with a standard caulking gun, and the narrow nozzle allows for good control. Just be sure to thoroughly clean the joint before applying the sealant, as good surface preparation makes a big difference in the final result. One thing to keep in mind is that this is a self-leveling product, so it's intended for horizontal joints only. It's not suitable for vertical surfaces because it will flow before curing. Wearing disposable gloves is also a good idea since polyurethane sealants can be messy to clean off your hands. Bottom Line: This is a high-quality, professional-grade concrete joint sealant that's easy to apply, self-levels beautifully, and cures into a durable, flexible, waterproof seal. It's an excellent choice for driveways, sidewalks, garage floors, and other concrete joints, making it an easy 5-star recommendation.

Great self-leveling sealant for cracks and between slabs on the porch to keep water from getting under the slabs. The sandstone look blends in very well. Looks great. Very pleased.

Used to seal a ~3/4" wide driveway apron gap. Gap was ~8" deep and varied 1/2-3/4" wide. I first filled the gap with 6" of paver sand. I then pressed in a foam rubber 3/4" OD backer rod ~1/2" below grade. Then applied the first of 2 tubes of caulk and let it set for 1 hour. Then applied the second tube of caulk to get the level just below grade and let it set overnight. As expected, there was some settling from the sloped ends of the apron. Still good enough. Next morning it was no longer tacky to the touch but far from fully cured. I'd expect full cure in 3-5 days maybe. Only time will tell how long it lasts but from previous experience this self-leveling polyurethane material is some incredible stuff.

I have been using this product for many years. I think it is the best self leveling product on the market. I bought it this time for a long1/4in crack in my garage floor. I first blew out the crack, then inserted a pencil size, foam filler and pushed it down into the crack about 1/4-3/8in to seal the bottom of the crack. If you don't seal off the bottom of the crack or void....you will use/waste a lot of product. Fill the crack slowly keeping the material slightly proud and then be patient. It takes a couple of days to completely cure (depending on the thickness of the application). Good stuff, very durable and better than the BB store prices.

This stuff is Amazing - just like any job; prep before you start the job!!! Clean the area ; sweep with a broom ; pull out any debris ; blow off with a leaf blower then , fill any deep areas with sand and or Backer Rod . The fact that this stuff is truely “ Self Leveling “ makes it a breeze to use . Use and Begin with Patience; all you have to do is hold the Caulking gun as it releases slow . Key is keep a very clean & Happy workspace ; keep a sweat cloth ; some wet paper towels and or roll of paper towels with a small bucket of water handy to immediately clean up any accidental spills . Any one out there needing extra income could make good money with this Great Product

The best adherence of any! Can't remove from concrete even using turbo sprayer! Use foam rod to stop caulk fall through. Nice professional appearance when dry! I recommend this over any others self leveling.

I have no idea if the product is good or not. I ordered 6 tubes and had to return before I used them. They gave me an immediate refund after shipping then a week or more later they put the charge back in my card. Their response was that they could see that I sent the products back via UPS tracking but did not get them. I used the same box they shipped to me and their QR code for shipping. Other than personally delivering the product I don't know what else a customer is to do. I then call Amazon support and they (Amazon support) gave me my money back but nothing from SIKA. I personally would not buy from them again. That doesn't mean its a poor product, but their customer support is unsatisfactory to me.

Just the right sealant I needed, I like the self leveling action. Just make sure you clean the gap/crack then pour it

This stuff is the business! The neatest expansion joints you’ll ever see, and all without any tape or tooling. It’s a bit pricey, that’s for sure. And you’ll need an American sized 29oz caulk gun, but just wow. So easy to use.

El producto es justo lo que esperaba. Le doy cuatro estrellas debido a que llegó abollado de la parte inferior, pero funcionó correctamente. Ojo con las instrucciones, el tubo no entra en una pistola de silicón convencional, es necesario comprar una más grande.

The self leveling property works well. It remains to be seen how durable the seal will be with time.
