"
(28 mm) total minimum thickness, interior floors only)
• Existing ceramic tile, VCT or non-cushioned sheetgoods provided they are single
layer only and well bonded to a substrate approved for tile (interior)
• Adhesive residue (except tacky or pressure-sensitive adhesive)
• Epoxy terrazzo (interior)

Substrate Preparation
Surfaces to be patched shall be free from oil, grease, dust, paint, concrete
sealers, floor finishes or curing compounds. Surface protrusions shall be
removed by sanding, scraping or chipping. After sanding, remove all dust by
vacuuming. (While sanding or scarifying surfaces that may contain silica sand,
use an approved dust mask. Never sand surfaces containing asbestos.) Do not
cover existing building expansion or control joints. Provide control joints where
specified. (For waterproofing applications, see Joint Details, page 3). Patch and
fill holes and voids with an appropriate TEC
®
surface preparation product.

Store in cool, dry location. Do not store open containers, nor leave containers
exposed to sunlight. Keep from freezing.
Shelf Life
Part A Maximum of 18 months from date of manufacture in unopened package.
Part B Maximum of 12 months from date of manufacture in unopened package.
Limitations
• For exterior wall applications, refer to local building codes for moisture vapor
transmission requirements.
• Not for use as a wear surface.
• Do not apply over wet areas.
• Do not apply to stainless steel or other metal surfaces.
• Do not use mastic adhesives over membrane.
• Do not use over dimensionally unstable substrates such as particle board,
