Part 2—Application

1. Mixing Perdüre mvt+

1. Do not alter mixing ratios in any way. Part I and Part II are supplied in the correct mixing ratios. Always mix a complete unit in the proportions supplied.
2. Mix material for approximately 3-4 minutes to form a homogenous consistency using a slow speed drill and a “jiffy” blade. Do not trap excessive air. Scrape all sides and bottom of container to ensure thorough mixing.
3. For primer/scratch coat material add 10% water to lower viscosity (16 oz. per 1.25 gal. of Perdüre MVT+)

2. Application

1. Primer/scratch coat: Apply with a squeegee and short nap roller at a coverage rate of 250ft².gal. After squeegee application, back roll with the short nap roller to achieve a uniform coverage. Allow to cure hard enough for foot traffic, about 3-4 hours at 75°F.
2. Bodycoat: Mix a outlined in step 1. If using optional pigment pack (subject to availability), add 1 to 2 quarts per 5 gal. of Perdüre MVT+ and mix thoroughly. Apply mixed material using a 1/4” V-notched trowel/rake or 1/4” V-notched rubber squeegee. Immediately backroll with a looped roller. A 1.25 gallon unit will cover 30ft² @ 1/16” thickness.
3. Broadcast surface with 30 mesh sand to excess (50lbs/100ft²) to achieve 1/8”. Broadcasting procedure should begin within 5-10 minutes after spreading resin to ensure adequate absorption of aggregate. Sweep and vacuum excess or loose sand after hardening, allow for 16-24 hours of cure time, depending on the temperature..
4. It is optional to add filler sand (30 mesh) to the Perdüre MVT+ during mixing; 1/2 to 1 gallon of sand (6-13lbs) per 1.25 gallons Perdüre MVT+, depending on if it will be broadcasted or to what degree it will be broadcasted. The subsequent broadcasted aggregate will sink less, yielding a more consistent finish. To yield a nearly smooth finish, add 1/2 gallon of sand per 1.25 gallons Perdüre MVT+. A nearly smooth finish may be preferred for thin topcoats needing a smooth finish, or if Perdüre EJF, flexible epoxy crack isolation membrane will be used. Apply a test patch or sample board to confirm the desired mix design

3. After 24 hours of the application of body coat, the surface will be ready to receive any cementitious or resinous flooring system

Apply the desired flooring system directly over broadcast surface, or sand filled smooth surface. Prime the surface with appropriate primer before applying the floor covering system.
