1A WHITE

Sikaflex 1a is the best.

Patio had a bunch of leaks this product sealed, all leaks, easy to use

This product came highly recommended in a youtube video I watched for how to repair the coping seal on my pool. And this product worked as stated. It's almost a year since I used it and it's holding up well. I am very pleased! It worked so well I looked for other places around my house that I could use the leftover tubes. It did well sealing the expansion joints and cracks in the driveway as well. This has solved the weed and ant problem and I've come to realize the water from the rain which runs down through the expansion joints is what causes the dirt erosion under the concrete and therefore the reason for the huge crack in one of the sections. Sealing these cracks should prevent further erosion. The only reason for the 4 star review instead of 5 is because 3 out of the 12 tubes were dried and were therefore unuseable.

My primary purpose for this caulk is for use on a travel trailer. My first use of this was about two years ago when I re-caulked most of my RV. That caulk is still in place, still white and sealed. I simply love it! I plan to use it on my house, my RV and anywhere else I need a good caulk. I found out about this product from watching a YouTube video made by a guy who used it on his motorhome. The guy stated that he had spent his career in the Commercial arena where it concerned all kinds of sealants and caulks. In his opinion, and I agree, this stuff is light years ahead of Dicor, which I have found to be a terrible product. It is rare that I give any product five stars, but his one deserves that rating.

Sika products are great. The 1a caulk/sealant outperforms any big-box-store caulk I have ever used. Ya, you will need a solvent for clean up of tools.

Works well

Waste of money tubes exploded in box. See pic

I used this mostly for its commercial durability. I used on my house between a 3ft. knee wall and a concrete path. First I pressurewashed, let dry, and applied the product. It is obviously stronger than your regular home improvement store brands. And purchased this way is much cheaper than individual tubes again at home improvement store. I am very pleased with this product and believe you will too.
