SIKASikaflex Construction Sealant - Limestone, Polyurethane Adhesive, Self-Leveling, Weatherproof, 10.1 oz Cartridge - Seals Joints, Cracks, Gaps in Concrete, Wood - Paintable, Durable, Flexible

Sikaflex is a great product. Unfortunately there must be a mislabeled batch floating around and I was unlucky to order two that came in a grey color I cannot use on my white vinyl windows nor window frame openings on a white house - with major rain coming. Very disappointing and I hope the next 2 come from a correct white batch.

As my home ages, things are aging and requiring repair. This certainly applies to the expansion joints around my house. Most specifically where the garage floor meets the drive way is the bane of my existence. As time and the weather have shortly chipped away at the board like material, I found my self having to constantly clean out all the debris that would accumulate from my chores and hobbies that I commonly worked on in my garage.Add insult to injury a beautiful Cactus Wren and it's family have made it their goal in life to pick through the gap now open vacated by the expansion board. Every morning I had to clean the mess that they would make sibling their beaks and dislodging more of the the old board.I finally had enough, I researched the various makers, I found the products at the big box stores had much to be desired with quality, plus when trying to use one of them the ease of use and flow didn't really help as I found myself squeezing the heck out of the caulk gun.Ultimately I removed the other product and got this brand. I found that once it was dried the durability, versatility was second to none. I used this product in the above mentioned area with a great result. The adhesion that this stuff has is awesome, allowing me to use in walls, floors, and even around metal that was anchored in the concrete but had developed cracks around the insertion site.I now keep at least one of these tubes around because I'm always finding another use and I have since noticed the Cactus Wren is now working in my neighbors driveway - which is fine by me.

Great sealant for concrete - used to seal expansion joints in concrete floor. Pretty close color match. Dries quickly and minimal VOCs.

Works as intended.

Easy to use very strong yet very flexible and lasts a long time Outdoors

Been using it for years instead of crappy DAP products. It really seals stuff to concrete well. I use it to protect rim boards I placed directly on my patio to enclose the back porch without pouring a new footer. Right on the slab. This stuff keeps the wood dry.

Used on a basement concrete floor crack and worked great

This product has great adhesion and makes an excellent caulk for sealing around doors, windows, trim, etc.
