NA 1550 Crack-Isolation Membrane is a flexible, thin, lightweight, load-bearing, self-adhered membrane over which ceramic tile and natural stone can be installed immediately with any polymer-modified cement mortar or epoxy mortar. Glue-down wood flooring also can be installed with any urethane adhesive. NA 1550 is less than 1/16" (1,5 mm) thick, lightweight, easy to position on the floor and cut to size with a razor knife or scissors. NA 1550 also provides excellent sound reduction between floors, having an IIC (impact insulation class) rating of 47, a Delta IIC rating of 16, and an STC (sound transmission class) rating of 52, all without a suspended ceiling.

Customer Questions & Answers
how many gals. do I need to cover 4,700 sq.ft.
Approximate Coverage at a thickness of 15 mils (0.38mm) is 71 sq feet. For this 3.5 gal bucket the approximate coverage is 250 sq ft per container, so you would need 19 Gallons (quantity 19 of this product) to complete your project.

How thick do you apply the maplelastic ci and how soon can you start tiling?
We recommend applying two coats, and Mapei's technical datasheet suggests a 20mils thickness for one application. After Maplelastic is added, we suggest waiting an hour to begin tiling. You can find more information on the technical datasheet listed under "Install & Product Documents."
