- Advantages
- Penetrates cracks that are less than 10 mils in width.
- Low viscosity, easy to apply.
- Penetrates porous surfaces.
- Protects concrete from water and chloride absorption.
- Bonds to dry and damp concrete.
- Consolidates weak concrete surfaces.
Applications & Uses
- Markets
- Compatible Substrates & Surfaces
- Basic Uses
- Seal concrete and protect it from the attack of water, salt and other chemicals.
- Penetrates and seals hairline cracks in concrete.
- Limitations
- Iso-Flex 609 Epoxy Crack Sealer is very exothermic in a large mass and should be spread onto the surface as soon as the mixing is complete.
- Apply to substrates above 50°F and below 90°F.
- Sealed concrete may have a blotchy appearance.
- Store between 50 - 90 °F.
- Installation
- Apply to a clean, dry, sound substrate that has no surface contamination.
- Some dampness in the concrete is tolerable but a dry surface is preferred.
- All cracks greater than 1/16” in width should be routed and caulked prior to applying the sealer.
- Mask any expansion joint sealant to prevent adhesion of the Iso-Flex 609.
- Mix the two components, Base and Curing Agent, with a low speed drill for 2 - 4 minutes.
- Quickly distribute the sealer onto the substrate with a squeegee or roller.
- Apply excess material to cracks and allow the sealer to seep into the crack.
- After several minutes remove excess sealer from the entire surface with a roller.
- Average coverage rate for the first coat should be 150 ft2 /gal.
- A second application at 150/300 ft2 /gal can be applied in 10 - 12 hours.
- For anti-skid or subseqent coating application, a 20 - 40 mesh sand may be broadcast into the second coat not earlier than two hours after application, but before the IsoFlex 609 becomes tack free.
- Clean-Up
- Clean tools, equipment and spills immediately with MEK or Xylene while still wet.
- Cured Iso-Flex 609 Epoxy Crack Sealer will require mechanical abrasion to remove.
- Maintenance
- In heavy traffic areas, the Iso-Flex 609 Epoxy Crack Sealer will eventually wear through.
- The surface can be resealed with new sealer.
- Contact manufacturer for recommended surface preparation and coverage rates.
