Endurathane Wall Panels
Installation Guide
The Manufacturer has provided these instructions as installation guidelines in accordance with ASTM E-330. The 
manufacturer, however neither installs the panels nor has any control over the installation. It is the responsibility of the 
contractor and/or the installer to ensure panels are installed in accordance with these instructions and any applicable 
building codes. The manufacturer assumes no liability for either improper installation or personal injury resulting from 
improper use of or installation.
Ekena products alone may not constitute a waterproof installation!
Flashing and caulking should be added as needed in such areas as transition from Ekena panels, ledgers and/or trims 
to other siding products, windows, and doors to control moisture and protect the sub wall assembly. Urethane paneling 
expands and contracts with temperature changes (average shrinkage on exposed paneling is about .039” per foot), so 
install panels with appropriate number of screws. Never leave cut edges exposed; exposed polyurethane will discolor 
and become obvious with exposure to sunlight. Use Ekena touch-up paint or color match with a good quality exterior 
latex paint. Any deviation from these standard installation instructions must be made watertight by use of a vapor 
barrier behind the product and then sealed with grout and painted with touch-up paint.
Basic Use
Ekena products are intended for interior or exterior nonstructural use as a lightweight veneer facing on masonry, metal 
framed, or wood framed construction for architectural aesthetics. These products are suitable for use on residential 
and commercial projects of many types. Ekena foam veneer panels are made of high-density polyurethane and molded 
from actual stone, rock or brick. A unique manufacturing process creates lightweight simulated stone panels that 
provide enhanced durability, water resistance, signicant weight reduction, and lower installation costs. No additional 
foundation or structural support is required. Installation is quick and easy, and costs far less than a full thickness natural 
or cement stone wall.
General Guidelines
Sheathing must be properly fastened to the framing according to building code requirements and/or the sheathing 
manufacturer’s recommendations. Ekena products should be applied over a sheathing that provides a smooth,  at, 
solid, non-expansive, stable surface. For exterior applications make sure sub wall assembly is weather tight before 
applying Endurathane Wall Panels. Wall sheathing should be weather resistant, or covered with a weather resistant 
barrier such as fanfold insulation, house wrap or building paper. Consult local building codes for complete information 
and requirements.
