Low VOC Water & Salt Repellent Iso-Tek^™ 8540

Product Details

• Benefits
  • Exceptional waterproofing - Penetrates deep within the concrete chemically reacting within the pores and capillaries creating a long-lasting hydrophobic surface that beads water
  • 100% breathable - Non-film forming. Allows moisture within the concrete to escape without adverse effects to the sealer. Does not trap moisture
  • Protects against chloride ion penetration - Forms an effective chloride screen dramatically reducing chloride ion ingress preventing deicing salt / chloride damage
  • Resists oxidization - Protects reinforced concrete by limiting surface water content and inhibits rust and corrosion of rebar in reinforced concrete
  • Resists moisture intrusion - Resists wind-driven rain, spalling, pitting and cracking.
  • Resist organic growth - Mold, mildew lichen and efflorescence
  • Department of Transportation - Meets or exceeds DOT specifications
  • Resists freeze thaw & thermal cycling damage
  • Resists ASR/alkali attacks by preventing the ingress of water
  • Provides ease of maintenance and good adhesion for paints.
  • Improves durability - Prevents capillary uptake of water and the aggressive substances dissolved in it
  • Natural flat finish - Does not change surface appearance, UV stable, will not breakdown with light exposure
  • Can be applied to cured, honed and polished concrete - Ideal for horizontal surfaces exposed to pedestrian and vehicle traffic, compatible with silicate densifi ers
  • Solvent based - Excellent for cold-weather applications
• Application

  Surface Preparation

  1. New “green” concrete must be properly cured. Concrete should obtain 80% of design strength, typically achieved within 14-28 days.
  2. The concrete substrate must be structurally sound and clean of oil, grease, dirt, wax, curing compounds, efflorescence, paints, previous sealers, adhesives and other contaminants that might interfere with the penetration of the sealer. Power wash, acid etch or mechanically scarify as necessary to achieve the desired surface condition. Allow for proper dry time before application. May be applied to slightly damp surfaces, although maximum penetration is achieved on dry substrates. Do not apply if standing water is visible.
  3. Surface and air temperatures must be at least 20°F during application. Surface and air temperatures should not exceed 95°F. Do not apply when temperatures are expected to fall below 20°F within 8 hours or when rain is expected within 12 hours following application. Keep material from freezing. If freezing conditions exist before application, let the substrate thaw before application. Do not apply during inclement weather or when inclement weather is expected within 12 hours.
  4. Crack, patching and expansion joint sealants can be applied before or after application; always test for compatibility and adhesion.
  5. Protect people, property, vehicles, window glass, roofing materials, plastic products, shrubbery, landscaping and all surfaces not set for treatment from overspray.

  Application

  1. Always test a small area before application to ensure desired performance, aesthetics, coverage rates and to verify application technique. Let test area dry thoroughly, 5-7 days, before inspection.

  1. Stir material throughly before and during application. Do not dilute or alter material for purposes other than specified.
  2. Apply with a roller, brush or low-pressure non-atomizing sprayer. Apply to saturation and roll or broom out any puddles until the sealer penetrates the substrate. If it starts to rain, stop treatment and cover the impregnated areas.

  Dry Time

  Typical drying time is 4-6 hours at 70°F and 50% relative humidity. Cooler temperatures or higher relative humidity can extend the drying time. Treated surfaces will be ready for pedestrian and vehicle traffic within 24 hours.

  Clean Up

  Clean equipment and tools with xylene. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

  Precautions/Safety

  Avoid contact with skin, eyes and clothing, do not take internally. Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use. For medical emergencies only, call ChemTrec (1-800-424-9300).

  Best Performance

  • Proper application is the responsibility of the user. • Will not inhibit water penetration through unsound or cracked surfaces with defective flashing, caulking or structural waterproofing. • Iso-Tek 8540 VOC should not get into direct contact with bitumen. • Spills should not be allowed to sit for extended periods of time, clean all spills in a timely manner. • Plastic windows will turn opaque when sprayed with this product • Make sure the most current versions of product data sheets and safety data sheets are being used.

  Coverage:

  1 coat: 100 - 400 square feet per gallon. 2 coats: 50 - 200 square feet per gallon. Variations in texture and porosity of substrate will affect the coverage and performance of the product.
