SIKA Sikaflex Self Leveling Sealant, Sandstone, 29 fl oz fL, Polyurethane, Sealing Horizontal Expansion Joints in Concrete, Accelerated Curing, Self-Leveling, Durable

If you’re looking for a sealant that combines ease of use with long-lasting performance, look no further than Sika Sikaflex Self-Leveling Sealant. This product has transformed my concrete surfaces, providing a clean, durable, and professional finish with minimal effort.Why I Love It:• Self-Leveling Magic: The true beauty of this sealant lies in its self-leveling properties. Once applied, it flows smoothly into joints, creating a flat, even surface without the need for tooling. This feature is particularly beneficial for those new to sealant applications, as it reduces the chances of uneven lines or missed spots.• Durability That Lasts: After curing, the sealant remains permanently elastic, effectively bridging gaps up to 1.5 inches wide. It’s designed to withstand the rigors of daily traffic, weather fluctuations, and the wear and tear typical of high-traffic areas like driveways and garage floors.• Quick and Easy Application: The product is a one-component polyurethane sealant, meaning no mixing is required. It’s available in both 10.1 fl. oz. and 29 fl. oz. cartridges, catering to various project sizes. The application process is straightforward—just clean the joint, apply the sealant, and let it level itself.• Paintable and Weather-Resistant: Once cured, the sealant is paintable with water-based, oil-based, or rubber-based paints, allowing it to blend seamlessly with your existing surfaces. It’s also waterproof and resistant to aging and weathering, ensuring long-term performance.Tips for Best Results:• Surface Preparation: Ensure that the joint surfaces are clean, dry, and free from oil, grease, or any other contaminants. This will promote optimal adhesion and longevity of the sealant.• Use Backer Rods: For deep joints, consider using a backer rod to control the depth of the sealant and prevent excessive use.• Curing Time: Allow the sealant to cure for 3 to 5 days for full strength. During this period, avoid any traffic or disturbance to ensure the best results.

I had a wooden expansion joint that rotted out. I cleaned out the expansion joint and put in exterior foam, leaving about 1/2 inch for the self leveling sealant. I have a slight slope away from the house and just jammed some cardboard in the joint in a couple of spots until the sealant started setting up and then pulled out the cardboard and added a little more material. Don’t have more than a half inch (depth) space to fill, you’ll just waste material. It levels nicely but you have to manage any slope. It won’t stay put, it will run. It dries like flexible rubber. I used a 29oz tube and another half tube to do 18 feet by 1” wide by 1/2 “ deep.

That amazon does not this item without damage. The product is good, i think... i wont know for a couple of years so all i know is that it is easy to use.and definitely looks better than the crack. But amazon doesnt protect the spout of this product from damage, and half of those i have ordered arrive with broken and bent spouts. The box the cartridge is shipped in is too big and the cartridge is allowed to shift and break its spout... which has a weaker support than 10oz cartridges

The product is fantastic, very happy with the result.Problem was Amazon shipping, 4 loose in a large box and the bad handling had bent all the nozzles, thankful none had broken off but the packing was dreadful

This product is not for sealing vertical cracks and joints, horizontal only. I have a few wide gaps between slabs in my driveway and I was told that could undermine it and cause it to sink. I got some sand and filled in the gaps, leaving a half inch depth at the top. You put this stuff in your caulking gun and then basically just pour it in. It's a little thicker than honey and it will flow and fill in the area so you don't need to be as precise as with regular caulk. Just move along, allowing the caulk to ooze out as you go. It is self leveling and self sealing because it flows and makes contact with all the sides. It is supposed to remain stretchy and keep the water out for a long time. I can't say anything about that because I only just applied it but it has dried to a rubbery consistency and it looks great.

Worked great for sealing cracks in my sidewalk. Make sure to follow instructions as it does self-level.I bought several tubes. Fixed several cracks. The results look great and it has lasted through a full year cycle without failing so far.

Works great have used many times!

This is the best sealer that I have ran across. You can't go wrong. It is easy to use!
