Is Silicone Better Than Elastomeric Roofing Materials

Silicone fails when applied to wood.

Is silicone better than elastomeric roofing materials.

Polyurethane succeeds with this material as well because it dries hard. A sealant is an elastomeric material that allows for 25 to 50 movement. It may seem like an easy fix to simply roll more elastomerics into place to prevent ponding. Silicone is quickly becoming the go to material in the flat roof coatings market.

Silicone is food safe. Silicone and polyurethane are two popular types of sealant. One of the leading reasons so many are now applying silicone roof coatings to their buildings is that silicone has a higher solids content than acrylic. Over time it is the better choice.

Its benefits range from leak free protection to improved aesthetic appeal of the roof to improved sustainability. It s an incredibly versatile material thanks to its chemistry and the many ways that it can be modified. Silicones weather better than other coatings with almost no erosion and they don t get hard or brittle. Silicones are moisture cured and humidity can even promote their cure.

As one may guess opinions aside there are pros and cons that exist for both silicone and acrylic roof coatings. Silicone is the best sealant for glass tile and metal while polyurethane works well on natural products such as wood. The nature of silicone products causes them to start compiling a dirty yellow appearance after only a couple years of application. Sealant is used to fill gaps to keep water and air at bay to allow for expansion and contraction of building materials and to enhance aesthetics.

Finally epdm has a shorter life span than silicone so depending on the application it will need replacing more often. Silicone is also good in ponding water situations. Consequently it offers vast possibilities. The pros of silicone.

In some applications the use of silicone can eliminate the need for a primer. Whereas acrylic roof restoration starts at a lower cost silicone elastomeric last longer and is more reliable. Elastomeric is highly popular for commercial roof contractors because of its density flexibility and durability. More than just an opinion this idea has proliferated the roof coatings industry for nearly a decade.

The hard drying makes polyurethane a lot more difficult to apply as it stiffens when out of the tube. This means that they can be applied thicker in a single coat without compromising on the application quality and the effectiveness of the coating after it has been cured. Elastomeric roof coatings perform as well as silicone roof coatings when it comes to ponding.
