MiraFlex Membrane A is a unique polymer emulsion waterproofing designed for use beneath ceramic tile, marble, quarry tile, below grade, between slab and under Miracote composition floors and decks. MiraFlex Membrane A is recommended for tank lining in potable water drinking systems.Questions? Contact us

MiraFlex Membrane A is based on a styrene butadiene latex that dries to form a tough, water and vapor resistant film. The latex is water based, environmentally friendly and does not contain any solvent. It is non-toxic and can be used in conjunction with potable water.

Applied by roller, trowel, spray or squeegee, MiraFlex Membrane A offers water protection together with excellent adhesion and is more resistant to impact than most membranes. It is applied to floors and molded up onto bases, over curbs, etc. without the use of any adhesive other than its own composition. Among the surfaces Membrane A can cover are concrete, tile and metal. For wood surfaces, consult Crossfield Products Corp.

The final thickness of MiraFlex Membrane A is 25 mils dry (standard application, two applications of 23-25 mils wet) and 30 mils dry (polypropylene fabric reinforced). Laboratory tests have established that MiraFlex Membrane A will bridge concrete cracks up to 1/8″ (3.2 mm) at temperatures as low as 0°F. However, prudent design would assume that the product can be expected to bridge a crack of up to 1/16″ (1.6 mm).

Where to Use
As a waterproof membrane directly under seamless composition floors (Miracote or other), ceramic tile, quarry tile, marble, etc. For application as mechanical equipment room waterproofing or computer access floor waterproofing for below grade or between slab applications, consult separate Crossfield Products Corp. specifications.

Install a minimum 4‟ by 4‟ test area site mock up for approval of

acceptable color, texture, finish, adhesion, and any other critical requirement acceptable to the owner prior to proceeding with the installation.
Verify current versions of product technical data sheets (PTDS), material safety data sheets (MSDS), and installation guides (IG) at www.miracote.com.

Protect materials from excessive heat and cold and regularly check wet film thickness with mil gauge and monitor consumption to ensure correct application thicknesses and rate are obtained.
