Sto Corp. Launches Joint Warranty with Oldcastle’s Amerimix Brand


Sto Corp., the innovative world leader in cladding, air barrier, coatings, and restoration systems, and Oldcastle’s Amerimix brand - a nationwide manufacturer of stuccos, mortars, and grouts, are pleased to announce a joint marketing agreement. This program will allow for the ease of combining StoPowerwall™ Stucco finishes with Amerimix Pre-Sanded, Concentrate, Scratch and Brown, and Pump Grade Sanded product warranties, giving contractors the advantages to both under one single warranty. The StoPowerwall™ Stucco System creates a more durable, impact resistant, colorfast exterior wall cladding. This lightweight cladding offers greater flexibility, with faster installation than traditional stucco.

The joint warranty program will include Amerimix Stucco Products AMX 750 FBC, AMX 755 FBC, AMX 745 FSB, and AMX 740 FSB. The warranty will cover these Amerimix Stucco Products in conjunction with using a StoPowerwall Stucco System. This dual warranty will allow for Sto to further extend its ability to offer a more extensive system solution to the entire North American stucco market. This will enable access to more geographically desirable locations from local demand. All stucco products should be used in accordance with Amerimix’s application guidelines and with the correct product compatibility.

“We are looking forward to this new relationship,” said Johnsie Beck, National Amerimix Brand Manager (aka Oldcastle Company, Inc.) “Amerimix Stucco products and the StoPowerwall System are a good match allowing for a complete warranty opportunity protecting the wall and the project with the best in the industry”.

Sto’s Powerwall finishes come in a wide variety of flexible, silicone enhanced, elastomeric or acrylic-based finishes that are either textured or smooth. Sto’s elastomeric finishes can bridge hairline cracks to keep moisture out – all of which add up to a more powerful cladding system. StoPowerwall finishes deliver excellent color uniformity and a wide array of tint choices using highly concentrated pigments that won’t dilute material like universal tints can. With a variety of textured finishes and smooth coatings and more than 1 million tint formulas, Sto puts custom design options at your fingertips. Choose from various coatings and finishes, including StoCoat™ Lotusan™, which has a pronounced self-cleaning effect, is highly resistant to mold and mildew, and has high water vapor permeability.

The terms of the new Sto and Amerimix warranty are the same as the StoPowerwall system warranties, up to 12 years, depending on the system configuration. For more information on Sto Corp. and the new joint warranty, please visit, or call (800) 221-2397.
