Moisture Vapor Barrier is capable of reducing the hydrostatic pressure emitted by concrete from 15 lbs/1000 square feet to less than 1 lb.(less than 0.05 perms). The presence of high moisture vapor emissions in concrete substrates should not exceed 3.0/lbs of moisture per 1000 sq/ft area within 24 hours, otherwise, it will adversely affect the adhesion of most conventional floor coverings and coatings.

Surface Praparation:
- The surface can be damp (no standing water) or dry. It must be clean, free from all dirt, dust, oil, grease, wax, paint, Curing agents or any contaminants that may inhibit proper adhesion of the coating. Note: Concrete can be fresh with a minimum of 10-14 days cure time.
- Concrete substrates should be prepared using standard methods such as steam cleaning to remove surface contaminants such as oils, fats, greases, waxes, sealers, paints, etc. Alkaline surface residue and laitance can be removed with a mechanical method such as shot blasting, grinding, bead blasting, diamond grinding, acid etching. track blasting, degreasing, solvent stripping, etc.
- After the surface has been clean and is dry, shot blast using a 50/50 blend of 280/330 shot to achieve a CSP 3-4 profile (texture similar to 60-80 grit sandpaper).
- All expansion joints should be filled with Mono-Caulk Polyurea Joint Filler
- It is the responsibility of the end user to identify which methods are suitable for concrete preparation given the specific conditions of the substrate and environment for application. Failure to adhere to these guidelines can result in product delamination, discoloration, blistering.etc. Testing is the responsibility of the applicator. Monopole bears no responsibility for failures due to any of the above conditions.
Mixing: Mix 2 parts A with 1 part B (by volume) for 3-4 minutes with a slow speed drill mixer. Do not dilute or alter mixture ratios. The mixed materials will have approximately 30-45 minutes of working time, depending on the temperature and humidity. Avoid entrapping excessive air into the blend when using high speed agitation. Apply the material immediately after mixing.
Application: Apply Moisture Vapor Barrier to the substrate with a notched squeegee, broom or any other proficient means. Roll the materials immediately with a 3/8" nap roller. Allow to cure a minimum of 24 hours.
Moisture Vapor Barrier is a high solids coating and may require adjustments in spray techniques. Use cross spray application procedure. Move the gun fast enough to avoid runs or sags.
- Spray Equipment: Conventional Spray-DeVilbis, Binks and Graco are suitable. Pressure pot equipped with dual regulators 3/8" I.D. minimum material hose, 070" I.D. fluid tip and appropriate air cap.
- Airless Spray: Pump ratio: 30:1 (min)". GPM Output: 3.0 (min).
- Material Hose: 3/8" 1.D. (min). Tip Size: .017"-0.21". Output PSI: 2100-2300. Filter Size: 60 mesh.
*Teflon material.
Brush, Roller or Squeegee: Use a pure bristle. Avoid nylon. Use a short-nap 3/8" synthetic roller with a phenolic core.
Multiple coats may be required to obtain desired appearance.
Avoid excessive re-brushing or re-rolling.
Excessive humidity or condensation on the surface during curing can interfere with the cure and can cause discoloration and may result in surface haze or blush. Haziness or blushing
must be removed by water washing before recoating. Higher film thicknesss, cooler temperature will require longer cure times and could result in solvent entrapment and premature failure.
Recoat in approximately 6-8 hours. At lower temperature, it might extend to 18-24 hours.
If the maximum recoat time has been exceeded, the surface must be abraded by sweep blasting or sanding prior to the application of additional coats.Application Note: When used as a top coat, a second coat is recommended.
Application Conditions:
- Normal Application: (60°F-85°F, Humidity 0-80%)
- Minimum Application: (50°F., Humidity 0%)
- Maximum Application: (90°F., Humidity 80%)

- Limitations
- Not UV Stable. Epoxies lose gloss, discolor and chalk in sunlight exposure. For Interior use only, unless protected by a pigmented U.V. resistant coatings such as Permashield 200,
- Permashield 2000,Monochem 610 or Permashield 100.
- Do not apply at temperature below 50° or above 90°F.
- Concrete must be cured for a minimum of 10 days and have vapor emissions of less than 15 lbs/1000 square feet, within 24 hours.
- Moisture Vapor Barrier must be cured for a minimum of 24 hours prior to exposure to water.
- Concrete must be clean, free of paint or sealers and must be a minimum of 2500 psi.
