Perdüre MVT+
Moisture Vapor Retarding System

---

Part 1 – Information & Preparation

General Information

Perdüre MVT+ is designed as concrete slab surface treatment when moisture vapor transmission exceeds 8lbs. of moisture as tested with the calcium chloride test procedure (ASTM F -1869), or for use when concrete slabs test higher than 80% as tested with the relative humidity probe test (ASTM F-2170)

Surface Preparation

Surface preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared to minimum surface profile of ICRI CSP-3 to a maximum CSP-6 as outlined in Düraamen’s Technical Bulletin # 1. Specific attention should be paid to the following:

• Concrete Placement
• Curing and Finishing Techniques of the concrete substrate
• Age of concrete
• Previous contamination of the substrate
• Present condition of the substrate

Also, the temperature and humidity conditions of the area to receive the flooring system should be checked. As optimum room temperature of 75°F with a minimum slab temperature of 60°F is required for proper cure of the resin flooring system.

Material Quantities

Guideline System Requirements for 1000ft2 – 1/8" thick
Product	Description	QTY.	Coverage
Perdüre E02	Primer/Scratch coat (add 10% water)	4 gal	2502ft/gal
Perdüre E10	Body coat	40 gal	252ft/gal
Filler	(30# mesh)*	500 lbs	0.5lbs/ft2

NOTE: Required total system thickness after sand broadcast is 1/8” as outlined. Add 10% potable water to Perdüre MVT+ for primer application only.

* It is optional to add filler sand to the Perdüre MVT+ bodycoat during mixing. 1/2 to 1 gallon of sand (6-13lbs) per 1.25 gal Perdüre MVT+. Adding the sand to the body coat will allow for the subsequent broadcasted aggregate to sink less yielding more consistent finish. Adding at least 1/2– 3/4 gallon sand per 1.25 gal of Perdüre MVT+ eliminates the requirement to broadcast sand, yielding a nearly smooth finish when needed. 1000ft² will require 200–400 lbs. of filler sand. Apply a test patch or sample board to confirm desired mix design.
