MOLD AND MILDEW RESISTANCE
PermaBASE was designed to provide extra protection against mold and
mildew. When tested by an independent laboratory, PermaBASE received the
highest possible ratings on ASTM G 21 and D 3273. The use of PermaBASE
in actual installations may not produce the same results as were achieved in
controlled laboratory conditions.
No material can be considered “mold-proof,” nor is it certain that any material
will resist mold or mildew indenitely. When used in conjunction with good
design, handling and construction practices, PermaBASE can provide increased
mold resistance. As with any building material, avoiding water exposure during
handling, storage and installation, and after installation is complete, is the best
way to avoid the formation of mold or mildew.
