## Description

When you need a high-performance adhesive that suits a wide array of both interior and exterior joints, the Sikaflex-1a self-leveling concrete sealant is the right choice. It's especially ideal for small joints found on windows, door frames, reglets, flashing, and similar roofing detail work. It also suits both vertical and horizontal joints. This sika self leveling concrete sealant works great in damp and in green concrete applications. The sika glue can be used in submerged conditions, including joints used in canals, reservoirs, runoffs, as a pool mastic, and similar. It's odorless and it won't stain your surfaces.

Review: Great stuff for Pool Decking - Great stuff. I used it to seal seam between the concrete deck and my pool tiles. Worked great. Not sure why they say it's self-leveling because it stayed in place on an overhead application. I used painters' tape on the vertical tiles to get a nice clean line.
Review: Excellent for Superior Walls! - Excellent for sealing Superior Walls as they age. Worked perfectly!

## Questions & Answers

**Q: is this product used at all in the marine industry on boats?**
A: No

**Q: What is the expiration date of these?  They are difficult to use if beyond expire date.**
A: I would not use this beyond its expiration date. Smarter to get fresh caulk as old caulk loses adhesion. This stuff is Soooo much better than anything else. But it needs to sit for 6-7 days before exposure to water in the bath or kitchen or paint anywhere else.

**Q: After I have filled the cracks can I apply more sikaflex on top of the existing sikaflex...Will it bond to itself?**
A: Yes and no. A cured bond break will exist, but if you need to increase the fill of the caulkable gap, no harm will be created. You can  reactive the existing caulk with a little acetone.  BUT if it's a vertical fill,  don't do it!  You'll have a mess in your hands and everywhere else....

**Q: I need to seal stainless steel to concrete in an underwater pool setting with chlorine, is this the stuff to use?**
A: I haven't had that kind of use for it, but this caulk seems very durable, and sticks pretty aggressively to everything.

### ⭐⭐⭐⭐⭐ Great stuff for Pool Decking

### ⭐⭐⭐⭐⭐ Excellent for Superior Walls!
*by J***D on January 8, 2026*

Excellent for sealing Superior Walls as they age. Worked perfectly!

### ⭐⭐⭐⭐⭐ Excellent product but incorrect description
*by 2***B on April 19, 2024*

I did not even attempt to use the Sikaflex until over a year after I purchased it, and then discovered that it expired one week after I bought it. So, it was over a year past expiration. But to my surprise, it was still in good condition! Very tough, strong adhesion, but Amazon’s description says it’s self-leveling, which it is not. I used it to bond shoe soles, seal leaks, and a tough caulking compound. A very good product that I will probably buy again.
