HANGAR BAY FLOOR FINISH. Use a high build epoxy coating
system on the hangar bay floor, as specified in MPI 212, Thin Film Flooring
System for Aircraft Maintenance Facilities. MPI 212 requires a two or three coat
flooring system with reflective topcoats consisting of a primer and a topcoat or
primer, mid-coat and topcoat. The mid-coat and topcoat must be of the same
material. This system is appropriate for use in aircraft maintenance hangars,
equipment maintenance shops and all other industrial floors where resistance to
abrasion, lubricants and fuel is required.
The color of the floor finish should be evaluated to determine the
reflectance needed or desired. The colors are generally white or light gray.
Discuss the selection of the system with the activity to verify the type and color
desired. Also verify the requirements for the applicator's certifications.
Note: An alternate floor coating for new construction is the White Dry Shake
System consisting of cement, pigment, special hardening admixtures, sand, and
||content||
\ grit /1/ as the topping to achieve increased lighting levels. The Dry Shake
must be applied in strict conformance with the material suppliers written
instructions. Use of a mechanical spreader is essential for a successful
application. Contact the NAVFAC Engineer Innovation and Criteria Office (EICO)
for information.
