New Specification For Fast Track Construction
AC•Tech Announces New Specification for Fast Track Construction Projects
DIVISION 03390 AC•TECH GO-EARLY TECHNOLOGY™ CONCRETE CURING, VAPOR REDUCTION & SLAB PROTECTION SYSTEM
Go-Early Technology™ is built on the AC•Tech 2170™ Fast-Curing, Zero VOC, 100% RH tolerant Vapor Reduction System that has long been recognized for its ease-of-application, high performance and consistent results in the concrete construction and resilient flooring industries.
Now, this same German-engineered ISO 9001:2008 manufactured epoxy resin has been formally tested here in the United States as a Type 1, Class C Liquid Membrane-Forming Curing Compound in accordance with ASTM C1315-11 testing standards.
This means that AC•Tech's Go-Early Technology™ offers Fast Track Construction Projects a One Coat, Division 3 Solution to Concrete Curing, Slab Protection and Vapor Reduction.
Consider the following Go-Early Technology™ application protocol and what it will mean for FastTrack construction projects:
1. Place concrete at 8th and 10 per plan. Do not put any silicate additives into original mix design or topically after placement.
2. Apply Light Broom finish (5-10 mils depth) at initial set. Skip cost (and substrate surface reactions) of hard trowel finishing.
3. 24 hours after initial set (and just prior to Go-Early Technology™ application) clean and vacuum concrete surface to remove any dust, dirt, and construction debris.
4. Mix the 2-component epoxy resin and quickly spread with a 10-12 mils squeegee and Backroll. Ensure entire concrete surface is covered, leaving no high spots uncoated.
5. Allow epoxy resin to cure 4 hours for foot traffic; 12 hours for mechanical resistance; 48 hours for chemical resistance (normal conditions).
6. Put all construction trades on the slab days to weeks earlier. While the concrete is curing under the Go-Early Technology™ membrane, the surface is dry, strong, and hard.
7. Put interior walls up after the vapor control resin has gone down. Mold and Mildew do not like “dry” drywall.
8. Install final flooring systems (at appropriate phase of your construction process) with no moisture testing / alkalinity testing / change orders required.
