A-70 Latex Concrete
(MIL SPEC MIL-PRF-21631)

Synthetic resin emulsion concrete that is trowel-applied to form a seamless, non-sparking surface for heavy duty areas and rolling loads. It is primarily designed for use between channels of floors in cargo ammunition holds. For that service, it is normally applied at between 1-1/4 to 2 inch (31.7 to 50.8 mm) thicknesses - minimum 1/2 inch (12.7mm) thickness. A-70 Latex Concrete can also be used as an underlayment where thicker application is required at moderate cost.
