Moisture mitigation system under any epoxy-based Dur-AFlex flooring system
Use with resilient flooring primers, adhesives or underlayments approved by their manufacturers as compatible with MVP- Application
Application Method/Spread Rate
Pour 2 parts resin into 1 part hardener and mix for 2 minutes using a jiffler-type mixer at 300 – 450 rpm. DUR-A-GLAZE MVP PRIMER is applied with a 3/16 inch V-notched squeegee and back-rolled with a 3/8 inch nap roller cover. Apply at a rate of 100 sq.ft./gallon to yield a dry film thickness of 16 mils. NOTE: Out-gassing may occur in very porous concrete. To address this, apply a second coat of DUR-A-GLAZE MVP PRIMER mixed with an equal amount of Cab-O-Sil. Apply using a flat squeegee at 250 – 350 square feet per mixed gallon.
Limitations
- For interior applications only
- Apply only to properly prepared, sound and stable concrete at least 5 days old.
- DUR-A-GLAZE MVP PRIMER is to be applied at substrate temperatures between 60° F and 90° F.
- Do not apply when RH of concrete is greater than 99% (at 40% depth of slab) or moisture vapor transmission levels are greater than 20 lbs/1000 sq. ft./24 hours.
- Recoat window of within 24 hours must be adhered to.
- Do not use as a stand-alone system
- Available clear only
- Does not prevent floor failures due to osmotic blistering. See note on this page under WARRANTY.
- Where Dur-A-Glaze MVP is used with vinyl tile, sheet vinyl, carpet, or any other resilient floor covering, the 10 year warranty is only valid if Dur-A-Glaze MVP is used with primers, adhesives and underlayment approved by their manufacturers as compatible with MVP.
Surface Preparation
This product requires preparation in order to perform as expected. Surface must be profiled, clean, dry, oil free and sound. Please refer to the Surface Preparation Guide on our website for more information. Perform anhydrous calcium chloride tests per ASTM F1869 for to determine moisture vapor emission rates and/or in situ probe method testing per ASTM F2170 to determine relative humidity levels. NOTE: If replacing VCT, note that salt concentration is typically higher where tiles meet. Dur-A-Flex highly recommends core analysis at intersection of joint lines prior to installation of any resinous floor system.
- Joint Guidelines
Construction, Expansion and Isolation joints are considered moving joints which allow horizontal and vertical movement between the slab and adjoining structures, such as walls and columns, helping to minimize cracking where the two meet. Prior to filling moving joints Dur-A-Flex, Inc. recommends “honoring” these joints by making a saw cut through the finished floor system at a depth of ¾” deep and ¼” wide with a diamond blade saw attached to a vacuum. A bond breaker such as backer rod (closed cell) must be added to the bottom of the joint. Be sure to mark the location of the joints prior to the installation of the finished floor. Control and or Contraction joints are considered nonmoving joints which accommodate shrinkage and relieve internal stresses during the curing process of the concrete. Fill joints as follows: Mix 1 part Dur-A-Glaze MVP hardener with 2 parts Dur-A-Glaze MVP resin and thicken with 3 parts Cab-0-Sil.
