The Madewell Quarterly
Madewell Products is proud to introduce our very first issue of The Madewell Quarterly! We have begun distributing quarterly newsletters to those interested in new product and equipment offerings, upcoming Madewell events, and helpful tips on the best type of material to use and how to apply our products in various conditions.
Madewell 1312S White Epoxy Coating Now NSF/ANSI 61 Certified
Madewell 1312S White Epoxy Coating is now certified under NSF/ANSI 61 for Drinking Water System Components. This certification allows Madewell 1312S to be applied on steel and concrete structures containing potable water. Although similar to Mainstay DS-5 in composition, performance, and application, Madewell 1312S is applied at 10-20 mils in one or two coats. Madewell 1312S White Epoxy Coating may be used in conjunction with any of our Mainstay mortars to restore deteriorated concrete structures. For more information on potable water linings, please visit our website. To access our listing on NSF's website, please visit NSF.org.
Idustrial Restoration Using Mainstay 714 Vinyl Ester Coating
Steel and concrete structures found in paper mills, chemical processing plants, and other industrial environments often contain high concentrations of acids and harsh chemicals. Vinyl ester resins are most commonly used in linings for these structures over other coatings due to their superior chemical resistance properties. Glass flake reinforcement is typically added to vinyl ester systems to block water permeation and increase temperature resistance.
Mainstay 714 Flake Glass Filled Epoxy Novolac Vinyl Ester Coating is resistant against a wide variety of chemicals, including many acids, most alkalis, and various solvents. The combination of vinyl ester resin and glass flake reinforcement produces a product that offers exceptional corrosion protection in many aggressive environments. The Mainstay Composite Liner may be topcoated with Mainstay 714 for the restoration of concrete structures in industrial applications.

Restoring Culverts with Mainstay ML-72 Mortar
The American Association of State Highway and Transportation Officials (AASHTO) recognizes the use of cement mortar lining as a method for restoring corrugated metal and reinforced concrete culverts. Horizontal pipes carrying sanitary sewage may likewise be rehabilitated using Mainstay ML-72 Sprayable Mircrosilica Restoration Mortar and protected using Mainstay DS-5 100% Solids Epoxy Coating. Calculating the thickness of a cement mortar lining to rehabilitate these structures requires some engineering. The calculations used to perform this task are similar to those outlined in ASTM F 1216 – Inversion Lining. However, differences in lining material structural properties must be accounted for.
The structural and physical properties of Mainstay ML-72 mortar make it an ideal candidate for restoration work of this type. Although similar in concept to lining a vertical manhole by centrifugal spray, significant alternative methodologies must be employed. It is not, for example, possible to make multiple wet-on-wet passes. As you can see from the photo on the left, we have begun developing spinning equipment, centering equipment, and methods of moving the mortar spinner through the pipe at a controlled rate.
If you have any interest in pursuing this type of work and would like to see a demonstration, please contact us.
The Switch to Boss Compressors
Madewell has switched from Atlas Copco compressors to Boss Diesel Utility Skid Compressors. These compressors provide numerous benefits:
- Easy access to engine components
- A 55 gallon fuel tank that can provide enough fuel to run for over a day
- Rugged and dependable design
To learn more about the modifications Madewell makes to these compressors, please visit our website. To learn more about Boss Diesel Utility Skids Compressors, please visit bossair.com.
The New Madewell.net
Madewell.net has recently undergone some major renovations! Our website now offers important information about new and existing materials, such as the most up-to-date technical data and product specifications. Madewell.net also provides videos and other educational resources for learning more about the need for products such as ours in various industries. At the new Madewell.net, you now have access to:
- Resources on manhole rehabilitation, including videos on the manhole rehab process and how corrosion occurs in a manhole.
- A "Potable Water Linings" section that provides information on our NSF approved coating and systems for restoring concrete in potable water applications.
- An "Industrial Coatings" section that focuses on the use of Mainstay 714 Glass Flake Filled Novolac Vinyl Ester Coating for industrial applications.
- Overviews of our various zoo and aquarium lining systems and which systems work best for different types of applications.
