What Does Elastomeric Mean?
You have probably seen the term “elastomeric” all around our website, and probably around the internet in your search for the perfect sealant or coating for your project. You know it’s a good thing and that it is a useful quality in a sealant, but what does that really mean to you as the handy-man or woman and homeowner?
It’s easy to think of elastomeric as synonymous with flexibility, meaning it is able to resume its original shape when a deforming force is removed. Coatings that are considered elastomeric expand and contract with the underlying layer (for example your roof, deck, or foundation). This is an important characteristic of a coating for you because due to a process called Thermal Shock, roofs and foundations expand and contract due to hot and cold weather conditions.
What Makes Elastomeric Coatings Better?
Traditionally asphalt and tar were used to waterproof roofs and foundations. The problem that would occur as they would get brittle over time. This was because the petroleum contained within these compounds tends to become outgassed over time, meaning it would leave the substance and lead to the brittle coating. Because it was so delicate, the coating would easily crack when thermal expansion occurred on a roof or settling occurred in a foundation.
That is why we use elastomeric technology in our coatings. Ames products do not crack… instead they flex (sometimes up to 1000%!) with the surface and remain in a continuous unbroken non-permeable film over the surface of your roof, deck, foundation, or basement. This is thanks to the acrylic and rubber that make up our products. They do not become brittle and lengthen the lifespan of whatever surface you apply them to.
We want to help you do it the right way the first time, and our elastomeric coatings and sealants ensure that. Call our offices if you have any questions about our products such as Maximum-Stretch or Elasto-Barrier and their industry leading elastomeric properties.
