ETRU is an authorized and licensed applicator of the product, SpectraShield®; a polymeric lining system leading product in the polyurea coating industry.  While SpectraShield® has a variety of utilitzations, it’s the only polymeric lining system of its type designed specifically for wastewater structures.  Think sewage treatment plants and wastewater facilities, transportation containers and vessels and even sewers lines and drainage systems. Designed specifically as an alternative for traditional cementitious and epoxy systems, SpectraShield® has been in use for over 25 years and continues to gain in popularity due to its economical, efficient and effective properties.

SpectraShield® cures in place and is comprised of an application of 3 layers.  The first layer is a moisture barrier with a coating of silicone-modified polyurea. The second layer is  made of an application of closed cell polyurethane foam that restores the structure to original levels by filling all voids, eroded areas, bug holes and missing mortar joints.  The final layer – the pink layer – is another layer of silicone modified polyurea that serves as a corrosion barrier.

Are you interested in specific applications for paint and spray coatings from ETRU? Listed below are a just a few of the many applications.  Give us a call or use our form to find solutions for your project.

SpectraShield® is fast.  It goes on fast and cures fast. The typical 7 foot manhole can be lined in less than one hour.

SpectraShield® has been used around the world for over 25 years for a variety of industrial applications.

The installed price of SpectraShield® 500mil application is less expensive than the typical ½” cement build back with 125mils of epoxy top coat. SpectraShield’s cost benefit advantage is matched by no other competitor!

★★★★★ | ETRU installed a furnace in my home in 2017. Because I was delighted with Ryan’s knowledge of the product, as well as his professionalism, I called him a couple of days ago to repair my air conditioning unit. Ryan is very thorough in diagnosing the problem but also educated me on the best overall economic solution. Ryan provides excellent and timely customer service. I will remain a loyal customer, and I highly recommend you give ETRU a call.

★★★★★ | This firm and Ryan solved my HVAC problems that multiple other firms were unable to. Felt so good about their work and problem solving and friendly service that I contacted them about my insulation spray foam on the house project and was also really impressed with their job on that as well. Highly recommended.
