Sikaflex - White - Construction sealant (White) - All-Purpose Polyurethane sealant - for All Types of Joints 1/2" or Smaller - 10.1 fl oz

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.

Good quality marine grade caulking compound

Definitivamente la calidad es recomendable para cualquier tipo de trabajo y acabar con problemas de fugas

This is an excellent product. It is very strong, ultra flexable, very easy to discharge from a caulking gun even in freezing temps. To boot, it unlike most silicones, can be painted. It is a high quality caulk/adhesive. I will buy more when the need arises.

Works Well. Priced Right.
