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 InformationMinimize InformationPerformance 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.
- 12 months when properly stored.
- 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.
