SIKASikaflex Construction Sealant - White, All-Purpose Polyurethane for Joints 1/2" or Smaller - 10.1 fl. oz - Weatherproof, High Elasticity, Paintable, Strong Adhesion

I have done a lot of caulking in my life... Like tens of thousands of feet. All I needed was some nice stretchy elastomeric white sealant to go around the inside of my aluminum window to drywall edge cap in my kitchen. I needed something paintable. This polyurethane sealant from Sika was just the thing. The local hardware stores don't have it and I am too far away from Smalleys/Beacon in western USA to pick up and I didn't want to spend money on gas to drive 2 hours to one. So I ordered this from Amazon and it showed up in a couple of days, Prime shipping from Las Vegas warehouse. The job was simple. Back the joint, blue tape the the black aluminum window frame, shoot it and tool it. Pull the tape and let it cure. As soon as it was cured I top coated it with the wall paint and it's been awesome for a year so far.

Great item! I have an old house, so this worked good on brick and around windows!

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.

Works as intended.

In my experience with caulk products over many years nothing compares. My regret is that I didn't find it sooner. I was happy to find silicone after watching cheap contractor caulk used in building our new home dry, shrivel, and crack before the home was a year old. And virtually no flex if there is any movement. 100% Silicone has it's merits, if you're satisfied with its color, because its non-paintable. It's also very hard to clean-up and remove now or later, and can be difficult to work with as it can get messy and you have just a few minutes to work it. And even after it dries, it attracts dust and whatever's in the air, regardless of whether it's clear silicone or colored. And it's not cheap. However. it does the job, holds up against the elements for years, works well if you don't want to paint, and it flexes. But the other issues just mentioned sent me on a journey of research and it paid off. Sika has a number of great sealants formulated for various needs. I generally use the PRO Select Construction Sealant around the house. I've also used the product designed for mortar. Some products are "no-sag" and others are self-leveling. It goes on smooth, is easier to work with, is less messy, has a longer working time, and easier to clean up than silicone. If you make a mistake or touch another surface with it you can often remove it with a damp rag. If sitting a while, citric orange solvent generally takes care of it. It also readily takes paint, which is recommended outdoors if you want it to last. Without paint, it doesn't hold up quite as well to UV and the elements as silicone, although much better compared to cheap caulk. This stuff also flexes, reducing the chance of separation in the event there's surface movement. It also doesn't dry up or degrade in the tube as fast as silicone. Another thing I learned recently. I came across a couple tubes 2 years past their expiration date and the product in both tubes performed like new.It's not cheap and some folks complain there's less in a standard tube than other caulks. But this is minor stuff if you want the best sealant for all the reasons I just covered.

Best sealant you could even use

Worked great

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