Foundation Coat

Permanently waterproof below-grade concrete masonry units with fiber-reinforced surface bonding cement.

Where to use:

Permanent positive side waterproofing of below-grade concrete block walls.

How to apply:

Trowel or spray applied, fiber reinforced, Portland cement based, structural coating. Additional Information

Performance Characteristics

  • Waterproof barrier Passes CRD-48 (Resistance to hydrostatic pressure).
  • Radon barrier Stops radon infiltration.
  • Durable Resistant to weathering action, excellent freeze/thaw stability and abrasion resistance.
  • Breathability Allow moisture to diffuse, preventing damage from moisture build-up in wall system.
  • Structural When applied to both sides of dry stacked concrete block to form a complete wall system.
  • Attractive Smooth or textured finish on the above-grade portion of foundation enhances overall appearance. Can be used on interior foundation walls for added protection with a plaster finish. IRC and IBC approved For structural wall system and waterproofing.

Surface Preparation

  • Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
  • Repair spalled areas, static cracks and voids with Conpro Set or Foundation Coat.
  • Substrate should have open-pored and textured surface.
  • Saturate substrate with clean water, (saturated surface dry/SSD). Wall should be wet when Foundation Coat is applied.
  • For best results on concrete, grind or abrasive blast (CSP 3). Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Profile (CSP).

Priming

  • No priming is required under normal circumstances.

Mixing

  • Mechanically mix using a low speed drill (400 – 600 rpm) and mixing paddle or mortar mixer.
  • Pour 5-1/4 quarts of potable water into a clean mixing vessel and slowly add all of the powder.
  • Mix continuously for 3 minutes to a uniform, lump-free consistency.
  • Add up to 1 pint of additional water if needed.
  • Allow to “breathe” for 1 minute and remix for 1 minute. This will improve workability and open time.
  • Do not over mix, as this will entrain air and cause damage to the glass fibers.
  • Replace 1 quart of water with 1 quart of K-88 Admix when applying additional coats.

Application

  • At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
  • Trowel or spray apply material to a uniform minimum of 1/8 inch.
  • Cove material at junction of wall and slab to prevent water entry.
  • Apply with a vertical motion and finish with a horizontal motion.

Curing

  • Keep damp with a fine mist of water for 24 hours.
  • Protect from direct sunlight, wind, rain and frost during curing period.

Clean Up

  • Clean tools and equipment with water immediately after use. Cured material must be removed mechanically.

Coverage/Yield

  • 50 ft.²/50 lbs. @1/8 inch.

Product Handling

Packaging
  • 50 lbs. paper bags.
Shelf Life
  • 12 months when properly stored.
Storage
  • Transport and store in cool, clean, dry conditions in unopened containers.
  • High temperature or high humidity will reduce shelf life.

Limitations

  • Do not apply unless substrate and ambient temperature can be maintained at a minimum of 40°F for 24 hours. Refer to ACI Cold Weather Application Guidelines.
  • Cold mixing water and low temperature will retard set. Hot water and high temperature will accelerate set.
  • Protect application from precipitation and high wind for at least 8 hours.
  • Do not add more water than specified.
  • Do not re-temper as this will damage the fiber glass reinforcing.
  • Avoid overworking material during placement.
  • Over mixing will cause damage to the fiber glass reinforcing.

Health and Safety

  • Product is alkaline.
  • Do not ingest.
  • Avoid breathing dust.
  • Avoid contact with skin and eyes.
  • Refer to Safety Data Sheet (SDS) for additional information.

First Aid

  • In case of skin contact, wash thoroughly with soap and water.
  • For eye contact, flush immediately with a high volume of water for at least 15 minutes and contact a medical professional.
  • For respiratory problems, remove person to fresh air.

Disposal

  • Dispose of material in accordance with local, state and federal regulations.

For Cement Based Materials

The gallons per minute volume of a rotor/stator pump is determined by the pump size (i.e. size 6 has a larger capacity than size 3). The pressure capacity of a pump is determined by the number of stages. Thicker materials and longer distances require higher pressure.

Yes.  Building a structure below grade with concrete block (CMU) requires close attention to drainage details and placement of positive side waterproofing.  Foundation Coat forms a permanent, continuous membrane that prevents water entry. 

Foundation Coat is a fiber reinforced cementitious coating that can also be used to coat laid stack CMU's.  Dry stack construction is eliminating the traditional mortar joints and troweling Foundation Coat on both sides of the wall.  Because block is not perfectly uniform it may be easier and faster to lay the CMU in a bed joint but eliminate the head joint.  The resulting wall is stronger than conventional masonry.
