Joint Filler Discoloration
Joint Filler Discoloration
Most flexible concrete joint fillers have the potential to discolor due to ultraviolet (UV) exposure, resulting in a change in color. The common chemicals makeups of these discoloring joint fillers are polyurethane-polyurea hybrids and semi-rigid epoxy. In many cases, they do not have UV protection. The discoloration is typically yellow, amber, or green. The length of time of when the discoloring to take place can be almost immediate to up to a few months, depending on the site and UV exposure. Once the discoloration has happened it cannot be changed back. Coloring the surface of the joint filler would be difficult to achieve due to the smooth texture and closed cell.
There is an exception: EZ Pour, aliphatic, pure polyurea joint sealant.
The best way to avoid discoloration of joint fillers is to use a UV-proof aliphatic material. At Solid Solution Products, we manufacture our very own called EZ Pour. EZ Pour is an aliphatic, 100% pure polyurea joint sealant. This is a top-notch sealant for horizontal concrete joints which physically outperforms what is in the market. It will not discolor, crack, separate, nor brittle. This makes it a great sealant for decorative and polished floors, as well as high hygienic areas such as food processing, grocery stores and silicone tech manufacturing.
If you are specifying a decorative or industrial floor where you cannot have any discolor, nor cracking, nor joint separation from the joint edge, EZ Pour is your best choice to get the job done.
