National Applied Construc-tion (NAC) Products announces a performance warranty to assure compatibility between approved thinset and medium bed mortars and its ECB Anti-Fracture Membrane for the life of the floor installation. This is the first warranty of its kind in the tile industry.

In making the announcement, Tom Duv, president and CEO of NAC Products, noted the benefit of the industrys first combined membrane/applied mortar system performance warranty. This is solid assurance to specifying architects, professional tile installers and building owners that newly installed floors are protected against reflective cracking and delamination between the substrate and floor surface for the life of the installation. Considering the cost of a failed installation, its a fantastic insurance policy.

Transferable to new building owners, the system warranty is issued on a project-by-project basis and is supported by all major manufacturers of A118.2 or better latex mortar, in partnership with NAC Products. The system warranty requires that floors must have full ECB membrane coverage for protection against 3/8-in. lateral substrate movement. A list of supporting thin-set and medium bed tile mortar manufacturers is available at the NAC Products web site, www.nacproducts.com.

ECB crack isolation membrane installation.

ECB crack isolation membrane utilizes a proprietary primer formulation that, combined with the adhesive formulation of the membrane, bonds to the substrate. This membrane/primer combination provides a matched surface for the adhesive pre-applied to the bottom of the membrane.

Proper installation of ECB membrane.

ECB Anti-Fracture Membrane is designed for use under floor surfaces that require protection from structural movement and for protection against Moisture Vapor Transmission (MVT) 10#/ 1000SF/24 HRS. Suitable installations include ceramic, porcelain, stone, marble, slate and granite tile, pavers and brick. Suitable substrates include poured, pre-stressed and pre-cast concrete, concrete backer board, mud beds, gypsum and lightweight concrete. NACs ECB Membrane is the original crack isolation membrane and the first to meet all ten ANSI A118.12 standard performance tests for crack isolation membranes:

4.1 Fungus & Microorganism Resistance
5.1.5 28-Day Shear Strength
5.1.6 Shear Strength after Accelerated Aging
5.2 Point Load Test
5.3 Robinson Floor Test (extra heavy-duty live load resistance of rolling wheels on tile)
5.4 System Crack Resistance
M-5.6 7-Day Shear Strength Test
M 5.4 7-Days Water Immersion Shear Test
M-5.6 12-Week Shear Strength
M-5.7 100-Day Water Immersion Shear Strength Test

National Applied Construction Products, Inc. pioneered anti-fracture membranes in the United States and invented self-adhering, sheet-applied crack isolation technology. Its ECB Anti-Fracture Membrane is the No. 1 architecturally specified, No. 1 lab and field-tested, and No. 1 contractor/owner preferred membrane in America. In addition to ECB, NAC sister products include Strataflex fracture-free waterproofing membrane, SubSeal liquid applied waterproofing membrane, SAM3 fracture-free sound abatement solution (for sound-rated ceiling assembly), and Super SAM fracture-free sound abatement solution (no ceiling assembly required).

The company also supplies proprietary primers, sealant, tape and hardeners that are critical to the correct installation and lifetime warranty of its membrane products. For more information about the NAC family of flooring solutions, visit website at www.NACproducts.com or call 1.800.633.4622.
