CBSI Celebrates Sto® Month in May
For Customers in Maryland and Beyond
Helping local builders make a great impression with exceptional coatings and surface treatments for Mid-Atlantic construction projects is what we do every day at Capitol Building Supply, Inc. (CBSI).
This May, CBSI proudly highlights Sto®—the world leader in inventive wall systems, moisture barriers, coatings, and other exterior building material solutions.
Featured Sto Corp. Surfacing Solutions
For 60+ years, Sto has developed wall coating systems that deliver energy efficiency and superior aesthetics for building construction, maintenance, and restoration.
Top solutions available at CBSI yards across the Mid-Atlantic include:

StoCast Brick
Custom-made, resin-cast bricks offer the beauty of traditional brick while integrating functional advantages: lightweight, flexible, durable, and easy to apply. Choose from 30 colors, patterns, and textures!

StoCast Wood
Ideal for multi-cladding designs, these flexible, pre-fabricated resin cast shapes celebrate original wood textures found in nature for a durable and cost-effective alternative to real wood cladding.

Sto Strike Defense
This fortification solution takes EIFS durability to the next level, providing high impact and puncture resistance to protect construction from woodpeckers and other threats.

StoSeal STPE Sealant
Designed for opaque wall and building restoration applications, this high-movement, non-sag, hybrid construction sealant is durable, flexible, and highly resistant to moisture and weathering.
