ABSTRACT-ASTM F3010-13 | Standard Practice for Two-Component Resin Based Membrane-Forming Moisture Mitigation Systems for Use Under Resilient Floor Coverings

ABSTRACT--ASTM F710-11 | Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring

ABSTRACT -- ASTM E96 | Standard Test Methods for Water Vapor Transmission of Materials

The Go-Early Technology™ system is installed in Division 03 of the CSI MasterFormat rather than Division 09, which allows for the immediate installation of all subsequent building elements, materials and flooring systems or coatings while also proving a smooth, durable and easy to clean surface. Because of it’s high level of performance, concrete substrates do not require moisture testing, curing compounds, concrete densifiers or hardeners or extensive repair due to impact damage, curling or cracking.

All cementitious underlayments and resilient flooring systems can be installed directly over the cured epoxy, including most resinous floor coatings. The epoxy is available in a 12 hour cure (AC•Tech 2170™) or 4 hour cure (AC•Tech 2170™ FC) formula, depending on use. AC•Tech 2170™ can be used on any indoor or outdoor concrete structures requiring moisture vapor reduction and alkalinity control.

AC•Tech (Allied Construction Technologies, Inc.) will warrant for a period of fifteen (15) years the listed AC Tech 2170™ Water Vapor Reduction System against material defects. In addition, AC•Tech will warrant for performance the water vapor transmission reduction as shown in the AC•Tech product data sheets and printed literature, provided that all the recommended floor preparation, mixing, application instructions, and any other technical information stipulated in AC•Tech literature are strictly followed. This limited warranty covers against performance failure due to concrete water vapor transmission as well as alkalinity up to pH 14 only and includes the following:

1. AC•Tech approved adhesives
2. AC•Tech approved cementitious underlayments
3. Floor covering systems (including epoxy, polyurethane and MMA systems)
4. All labor charges involved in removing and replacing flooring in the area under warranty

Should the AC•Tech 2170™ System fail due to elevated levels of moisture vapor or alkalinity the failed flooring composite will be replaced in the areas of failure at no cost to the owner.

If there is any suspicion or uncertainty regarding the quality or contents of the concrete or the previous building usage, AC•Tech recommends that additional testing (core testing, pull-off testing, etc) be done to ensure the concrete is suitable for installation. Should it be found to be unsuitable, the testing results will inform the AC•Tech technical team on the severity of the problem and help develop a long-term technical solution for all parties that is warrantable.

Waiting for concrete trenchwork to cure and then dry can introduce a significant waiting period into a fast-paced renovation or tenant improvement project. AC•Tech's Go-Early Technology™ can cut 3 weeks off this 4 week waiting period while also providing the final moisture, alkalinity, and curling control required of final flooring systems.
