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.
Although it may seem like an investment this premium product has the unique ability to permanently control moisture vapor emission rates of up to 20lb / 24 hr / 1,000 ft. This product reduces the permeance of moisture vapor through concrete substrates to levels that are acceptable for the installation of hardwood flooring, carpet and tile. Flooring is protected and kept dry eliminating the risk of mold and mildew. The high performance and quick installation features of this system make it an ideal solution. Meets ASTM F3010 for vapor permeance.
Supplied as a two-component kit and easily applied with a squeegee, nap roller or brush, the Vapor-Tek 440 can be used on a variety of horizontal concrete applications. Recommended for areas with high risks of moisture intrusion, hydrostatic pressure and vapor transmission such as basements and warehouse floors. For interior use only, grinding or etching of the surface is recommended prior to application. Keep in mind this product has a quick set up time. Once Part A and Part B are mixed you have 5-25 minutes to apply the product before it begins to harden. Mix in small batches following the 2 Parts A to 1 Part B mix ratio to extend the pot life.
A high gloss, clear finish makes this product unique. Used as a primer before installing a durable concrete coating system or flooring such as hardwood, tile or carpet. It is recommended a calcium chloride test be performed prior to application to determine if this product is right for you.
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 EPDM Squeegee. 3/8” nap shed-resistant roller is recommended if back-rolling. A paint brush may be appropriate for cutting in or small-scale applications. Spiked shoes, mechanical mixing device 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.
APPLICATION:
Due to short pot life, we recommend immediately pouring entire contents of mixed Vapor-TekT 440 onto the floor in a long bead approximately 12 - 18 inches wide. Use 3/16” notched squeegee to spread material evenly at 10-20 mils to a uniform thickness.
As material is being spread, a second applicator can back-roll material using a 3/8” shed-resistant woven roller. Roll evenly across squeegee passes to minimize application lines. Do not back-roll material once Vapor-Tek 440 begins to tack up. This can interfere with self-leveling process. Use a new mixing pail for each kit.
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. Keep in mind the Pot Life is 5-25 minutes. Once the pot life has been reached the product can no longer be applied. Mix in smaller batches following the 2 Part A to 1 Part B ratio to extend the pot life.
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
CLEAN UP
Clean up mixing and application equipment immediately after use. Use acetone or xylene. Follow solvent manufacturer’s safety instructions. Be sure to follow all local, state and federal regulations when disposing of materials. Use “waterless” hand cleaner to remove dried material from skin.
PRECAUTIONS/SAFETY
Refer to the SDS sheet before use. Safety precautions must be strictly followed during storage, handling, and use. Personal Protective Equipment (PPE) should be worn at all times. PPE will include (but is not limited to): Safety glasses with side shields and high-quality nitrile gloves.
MAINTENANCE
To maintain the appearance and extend the life of the newly sealed surface, it is imperative to have a routine maintenance program. Dirt and debris that is tracked over a finished floor will quickly scratch and dull the surface. Place walk-off mats at entrances. Sweep and mop/scrub floors regularly using soft bristles/pads and a mild cleaner. Some cleaning products and equipment or improper use of these can damage a surface. Remove spills quickly to minimize damage and/or stains. For systems that support parked vehicles or other heavy items on rubber wheels, place a small piece of nonporous material, such as sheet metal or plexiglass between the tires and floor to prevent tire marks. Reapplication may be necessary in heavy traffic areas.
SHELF LIFE
12 months from date of manufacture when stored indoors in the original unopened container at 55°F – 85°F (13°C – 29°C) in a dry location with humidity below 65%. Do not allow materials to freeze.
CURE TIMES (75°F) 50% RH
