Stop water seeping through concrete and masonry wall by applying crystalline waterproofing slurry to the interior wall surface.
Where to use:
Waterproof concrete tunnels, storage tanks, foundations, wastewater storage and other demanding applications.How to apply:
Spray or brush applied, capillary/crystalline slurry, for positive and negative side waterproofing of concrete structures. Additional InformationPerformance Characteristics
- Waterproofing 2 coat application will withstand 57 ft. hydrostatic pressure.
- Permanent Non-reversible chemical reaction develops crystalline structure in capillaries that block liquid phase water.
- Durable Excellent freeze/thaw stability and abrasion resistance.
- Very low permeability Resistant to deicing salts, chloride, and chemical attack, and environmental pollution.
- Radon barrier Stops radon infiltration.
- Breathability Will not cause damage to structure by restricting moisture vapor flow.
- Two colors Available in white and gray – use in alternate coats to ensure proper coverage.
Surface Preparation
- Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
- Grind or abrasive blast (CSP 3) concrete to achieve an open-pored surface. This is essential to allow the crystalline structure to grow into the cement capillaries. Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Profile (CSP).
- Stop active leaks with ProMasonry Hydraulic Plug.
- Saturate substrate with clean water, (saturated surface dry/SSD). Wall should be wet when Conpro Super Seal is applied.
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 quarts of potable water and 1 container of Conpro Super Seal Admix into a clean mixing vessel and slowly add all of the powder.
- Mix continuously for 3 minutes to a uniform, lump-free, slurry-like consistency.
- Add up to 2 pints 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 excess air.
- Do not re-temper.
Application
Walls- At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
- Clean and pre-stripe non-structural cracks (up to 1/16 inch) with one 4 inch wide, 50 mils. application of material.
- Dynamic cracks, joints and transitions (wall-to-slab) must be properly detailed with a closed cell backer rod and polyurethane sealant. Refer to SWRI Sealants, The Professionals’ Guide.
- Apply 4 – 6 inch wide stripe of material over cured sealant. Embed mesh fabric while material is plastic.
- Apply a 50 mils. coat over the entire surface with a stiff bristle brush or spray.
- Work the first coat into the substrate using a circular or figure 8 pattern to fill all voids and pores. Do not exceed 60 mils. per coat.
- Apply a second coat once the first coat is thumb-print hard.
- For trowel applied applications, reduce the water demand to achieve a mortar-like consistency.
- Broadcast Conpro Super Seal powder in 2 passes at 90° to each other to ensure uniform coverage of 2-1/4 – 2-1/2 lbs./yd.² (1/4 lbs. per ft.²) during the floating process.
- Mix 1 part Conpro Super Seal Admix with 5 parts water.
- Apply mixture uniformly with a low pressure sprayer.
- Finish as specified for concrete finishing.
Curing
Walls- Mist cure 3 – 4 times per day for 3 days or moist cure with wet burlap and polyethylene for 3 days.
- Protect repair from direct sunlight, wind, rain and frost during curing period.
- Dampen with a fine mist of water for 24 hours or moist cure with wet burlap and polyethylene. Alternatively, apply ProMasonry Cure & Seal.
- 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
- 150 ft²/50 lbs. @ 50 mils.
Product Handling
Packaging- 50 lb paper bag and 22 oz. plastic container of Conpro Super Seal Admix.
- Bag – 12 months when properly stored. Admix – 18 months when properly stored.
- Transport and store in cool, clean, dry conditions in unopened containers.
- High temperature or high humidity will reduce shelf life.
- Protect Admix from freezing.
Limitations
- Do not apply unless substrate and ambient temperature can be maintained at a minimum of 45°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 apply over active leaks. Treat leaks first with ProMasonry Hydraulic Plug.
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.
