Moisture Barrier and Vapor Blocker for Concrete Floors

In Stock, ready to ship
$0.00

The WiseBond® Moisture barrier and Vapor blocker for concrete flake and metallic floors. This moisture blocker can be applied between 3 to 5 mils making a gallon go over 300 square feet depending on concrete floors surface conditions. Used as a primer coat, it will help keep moisture and air from coming up from concrete floors, eliminating unwanted bubbles and pinholes when applying epoxy, polyurethane floor coatings.

NOT FOR SALE YET!

Our 1-Gallon Moisture and Vapor Barrier kit is primarily made for concrete floors where epoxy and flakes or a metallic epoxy floor will be installed. It is a 2-component solvent-based urethane primer, with 97% solids, low less than 40 g/L VOC, class 1 vapor barrier that meets ASTM-E96-E93.



We do not offer samples of our products. Why not?

This moisture barrier coating stops water vapor transmission, to less than 1/2 pound per 1,000 sq. ft. The material is a unique water vapor barrier which opens up the possibility of applying high-performance resinous coatings to uncured or moisture-laden concrete.

With exceptional penetration, it will not blister into the concrete’s porous surface. The specific chemistry of the material generates a mechanical interlock with superior bonding and a bond strength exceeding that of most traditionally applied epoxy primers.

Warranty of this product, when used according to the directions, is limited to refund of purchase price, or replacement of product (if defective), at manufacturer’s or seller’s option.

MIXING 

Organize a clean mixing station that is out of the way and does not block the progress of applications. Preparation is critical! Do not confuse Part “A” and Part “B” with one another or mix too far in advance.

This is a 3:1 ratio mixture. Pour 1 part B into 3 parts A, in that order. This kit is premeasured for convenience. Avoid pouring product down the inside of your mixing pail, as this will make it harder to mix the 3:1 ratio properly.

With a power drill and mixing paddle. mix both parts A and B for 5 minutes at medium speed. NOT high speed! A medium speed will help prevent air infusion (bubbles) into the material.

Once mixed, immediately apply the combined moisture barrier product on the concrete floor. Pour completely out in a long trail along the farthest side from your exit door. Work backwards for the application.

Do not leave the mixing bucket upside down to drain onto the floor. There is the possibility that unmixed portions of A or B may spilled on the side of the container. This unmixed product could drain onto the floor, creating a spot that will not cure.

Any unused portion of the concrete floor moisture barrier product left in the pail will cure at an accelerated rate rendering it useless. Likewise, if the material is left in your mixing pail too long before applying to the concrete floor, the cure will accelerate quickly and be unusable.

NOTE: Clean mixer paddles, clean out or replace mixing containers, and roller pad covers in a reasonable fashion. This ensures the chemistry of A and B remain consistent, especially over large concrete floor projects.

HOW TO APPLY CONCRETE MOISTURE BARRIER AND VAPOR BLOCKER

  • Concrete moisture vapor barrier may be applied with a paint roller or squeegeed and then back-rolled.
  • Keep an eye out for thick roller marks and feather out overlaps. Always keep a wet edge!
  • Select nap size approximately 3/8” or (9.5 mm).
  • Rollers should be superior quality with a phenolic core.
  • “De-fuzz” roller by wrapping tightly with masking tape and removing the tape. Or stretch out 2-3 feet of masking tape and roller the sticky side to remove lint and fuzz.
  • Large areas may require 18” (46 cm) rollers and wider squeegees.

The concrete surface must be cleaned thoroughly, sound, and profiled mechanically, as for all specialty sealers. This product is not a shortcut for poor surface preparation.

Apply when surface and ambient temperatures range between 50 F (10 C) and 90 F (32 C) and will remain that way for 24 hours.

After establishing room dimensions, before mixing the product, place a short piece of masking tape on the wall to correspond to the “distance” one gallon should cover. Work across the narrowest width of an area where practical. Work backwards to an exit way from the wet moisture and vapor blocker. Always track your coverage rate for each gallon (3.8 liters).

NOTE: Mask all areas requiring protection; product will stick to most everything.

Always wear appropriate PPE (personal protection equipment) and be sure there is adequate ventilation. This product should be acclimated to room temperature, before application. Ideal room temperature is 78 degrees and 50% relative humidity.

  • Do not apply on visibly wet or moist concrete.
  • Spread concrete moisture and vapor blocker evenly over the area with a roller or squeegee. Areas adjacent to walls should be “cut in” with a paint brush. Apply no more than 3-5 mils wet.
  • Barrier material should be dry to the touch and tack-free (approx. 4 – 6 hours) before applying concrete flake floor epoxy base coat or a decorative metallic floor base coat. This ensures the proper bond between the moisture barrier and the epoxy top coat.
  • NOTE: If the product is allowed to dry longer than 24 hours, the moisture barrier surface must be screened sanded with a 100-grit sanding screen on a rotational floor machine, and the material must be reapplied.
  • Clean up application materials with a solvent such as acetone or xylene.
  • For use by trained professionals that have read the complete SDS.
  • Contact your local government household hazardous waste facility for more specific information on disposal of unused product. Upon curing, left over catalyzed product is not hazardous.

COVERAGE: Applied between 3 to 5 mils thick, one gallon will cover 300 square feet depending on concrete floors surface conditions.

CAUTIONS: KEEP OUT OF REACH OF CHILDREN. Inhalation: Avoid prolonged breathing of airborne dust, particularly present during mixing. Use NIOSH approved respirator for nuisance if threshold limit values are unsafe. Skin Contact: Skin contact may cause irritation. Remove contaminated clothing and wash affected skin with soap and water. Launder clothing before reuse. If symptoms persist, seek medical attention. Eyes: Wear safety eye protection when applying. Contact with eyes may cause irritation. Flush eyes with water for 15 minutes. If symptoms persist, seek medical attention.
