Subkote 1 Underlayment

(MIL SPEC MIL-PRF-3135, Type I, Class 1)

A trowel-applied, synthetic rubber latex mastic used to smooth a deck overall to receive finishes of uniform gauge thickness. It is resilient, flexible and sound deadening, yet provides good indentation resistance. Subkot 1 is normally applied from 1/8 inch (3.1mm) to 1.5 inch (38mm) thickness - not to exceed 3/4 (19 mm) thickness per application.

Typical Uses:

-To smooth a deck overall to receive finishes of uniform gauge thickness
-For lightweight filing
-To create pitch to drains
-Thin ceramic tile bed
-To underlay Magnesite
