Product Description

VAPOR-TEK 440: MOISTURE VAPOR BARRIER COATING

A moisture vapor barrier coating designed to waterproof concrete floors. Controls moisture vapor emission rates up to 20lb/24 hr/1000ft prior to the application of hardwood flooring, carpet and tile. (Keep in mind this product sets up quick. Once Part A and Part B mix, it needs to be applied within 5-25 minutes. After the pot life is reached, discard any remaining material.).

Product Details:

• Helps reduce effects of moisture vapor transmission
• One coat application, no VOCs – no odor
• May be used as a primer to an epoxy floor system or stand-alone product before applying flooring
• Ensures protection of moisture sensitive floor coverings
• Stops dusting and allows for easy cleaning
• Will form an excellent bond to concrete – will not delaminate when exposed to moisture emission rates up to 20lb/24 hr/1000 sq. ft.
• Meets ASTM F3010 – Standard Practice for Two-Component Resin Based Membrane-Forming Moisture Mitigation Systems for Use Under Resilient Floor Coverings

Cure Times: (70F): Pot Life – 1 gallon volume: 5-25 minutes // Tack Free (dry to touch): 3-8 hours // Recoat or Topcoat: 12-24 hours // Full Cure (Heavy Traffic): 3-5 days

Surface Preparation:

Surface must be clean, dry, and completely free of loose particles, grease, oil, or any substance that would interfere with proper bond. Moisture content in the concrete should not exceed 6%. Perform vapor testing to verify that the vapor pressure is below 20lb / 24hr / 1000 sq. ft. Surface depressions or surface irregularities should be filled smooth and surface cracks, grooves or other non-moving control joints should be filled before application.

When applying directly to concrete, we recommend either mechanical scarification or acid etching until a suitable profile is achieved (CSP Level 3). If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to application. Concrete must be dry for at least 24-48 hours prior to application.

Recommended Tools:

Best applied using 3/8” nap shed-resistant roller. A paint brush may be appropriate for cutting in or small-scale applications. Spiked shoes, mechanical mixing device, and mixing containers are also recommended.

Mixing:

Combine two (2) Part A to one (1) Part B, by volume. Kits come prepackaged and should be used in their entirety and should not be broken down. Mix using slow speed to avoid whipping air into the coating. Improper mixing may result in product failure. Once the material is opened, it cannot be re-sealed for later use. Using a mechanical mixer, mix Part A in original container at low speed for one (1) minute. Once mixed, pour Part A into larger mixing container (5 gallon pail recommended). If applicable, pour color additive into Part A and mix for an additional one (1) minute. Add Part B into Part A and mix on low speed for three (3) minutes or until uniform. Do not combine more material than can be applied within a 10 – 15 minutes timeframe.

Application:

Using a brush, cut in any edges. Pour remaining material into a roller pan and apply using a 3/8” nap roller. Apply in a smooth, even, uniform manner. To help prevent visual differences in application be sure to minimize the time between tie-ins. Use control joints or natural breaks as breaking points between mixes. Continue to blend overlaps and roller marks. Vapor-Tek 440 does not self- level, so coating will cure with defects that are visible. Reroll areas that do not look satisfactory. Do not back roll coating if it begins to tack up. This could result in an orange peel texture and/or a whiteish haze in the coating. Applying the coating thicker then recommended or rolling the material when sticky will cause bubbles, roller lines, and create an inconsistent appearance.

Temperature Limits:

Surface and air temperatures must be at least 40°F and must not exceed 90°F during application with relative humidity below 80%. Floor temperature must be at least 5°F over the current dew point.

Application Notes:

• Do not apply at a temperature or thickness not recommended. • Do not delay in pouring mixed material onto the floor as mixed material has a short pot life and will start to harden quickly. • Do not apply over loose or unsound concrete, asphalt or bitumen substrates, glazed tile or nonporous brick and tile, magnesite, copper, metal, polyesters, or elastomeric membranes. • Moving joints and shrinkage cracks may reflect through system. Joints that are designed to move may reflect through the finished flooring system if the are not honored. • Tire marking may occur. • KreteTek Industries Inc. is not responsible for entrapped moisture and/or water underneath applied coatings with a low rate of water vapor transmission which can deteriorate concrete resulting in a cohesive failure within the concrete surface.

• This product should never be exposed to water until it is fully cured.

• This product will not prevent failures caused by insufficient surface preparation, improper applications, Alkaline Silica Reactions, iconic compounds or soluble salts in the concrete.

• KreteTek Industries Inc. is not responsible for failures caused by cracks in the concrete, pin holes or damage caused by use.

• Upon application to the concrete, outgassing may occur resulting in pin holes or voids when the air is displaced. If this occurs, reapplication is necessary. The surface should be lightly grinded and dust should be removed. Make sure the surface is dry and re- coat. In severe cases, the use of a patching material made with a thickening agent may be needed on these pin-holes and voids.

• Thinner applications than recommended may result in insufficient moisture vapor protection

• Any un-reacted alkaline silicate compounds within the concrete can result in osmotic action/water vapor transmission that will channel these water soluble compounds to the surface where they can effectively break the bond of the applied system as well as prevention penetration of the coating into the substrate.

• All concrete slabs must be at least 4” thick with a functioning vapor barrier. • Physical properties are typical values and not specifications.
