ElastiPoxy Joint Sealant & Crack Filler Kit

ElastiPoxy Joint & Crack Repair kitElastiPoxy is a two-component flexible epoxy. No polymer additives, 100% solids, zero VOCs. Low viscosity, self-leveling epoxy for filling cold joints, saw cuts, large cracks, and spalls in concrete slabs. Impact-resistant. Virtually indestructible under high water pressure or heavy traffic. Chemical and water resistant. When mixed with sand, it provides a strong, rigid filler for filling cracks or surface defects in concrete and masonry.

  • ELASTICITY – Adequate elongation to allow for the natural expansion and contraction of concrete or masonry.
  • TENACIOUS BOND - Adhesion to damp surfaces, making it ideal for basements, slabs on grade, and driveways.
  • ZERO VOCs - Environment- and user-friendly.

The Old Ways to Repair Joints in Concrete Slabs

Hydraulic cement is waterproof but does not bond well to concrete. That’s why it needs an inverted V-groove. It is also very rigid – more than concrete – and does not move with the concrete. Not suitable for moving joints! After a couple years, this rigid rod gets loose and efflorescence (white powder) starts appearing around its edges, soon followed by drops of water. Using a patching compound instead will not provide a flexible and waterproof joint.

Polyurethane caulk is both waterproof and flexible. It bonds well to the surface of dry concrete but wicking water and efflorescence gradually weaken the bond. It has no strength and easily separates due to water pressure, efflorescence, or traffic.

These common methods provide only a superficial and temporary fix.

Coverage

repair crack in concrete floor with ElastiPoxy

Based on a routed out joint or crack 1/4" wide by 1/2" deep and using pure epoxy (no added sand), the small kit (2 quarts of epoxy) will fill approximately 75 linear feet. The medium kit (2 gallons of epoxy) provides four times more volume – 300 linear ft.

Using the small 2-quarts kit and 4:1 sand to epoxy ratio, you will need approximately 20 lbs. of dry sand for the mixture to fill about 375 ft. of cracks ¼” wide and ½” deep.

Repair Control Joints, Cracks, Leaky Basements, and Spalls

The ElastiPoxy Joint & Crack Repair Kit is easy to use by both contractors and homeowners. Since the pure ElastiPoxy is flexible and self-leveling, use it for:

  1. crack in slab repair with ElastiPoxyWAREHOUSE, FACTORY CONCRETE FLOORS - Protect edges of contraction control joints against heavy wheel loadings.
  2. SAW CUTS - Seals saw cuts in foundation slabs, basement floors, and garage floors against dirt, water, vapor, and gases, including radon.
  3. BASEMENTS - Seal floor-to-wall joints in basements and buildings against water, vapor, and radon gas.
  4. DRIVEWAYS - Seal control joints and the large joint to garage floor against dirt, water, freeze-thaw cycles, and salts. Fill pits and minor defects.
  5. SIDEWALKS - Repair control joints and the troublesome sidewalk joint next to the building foundation.
  6. CONCRETE STAIRS - Fixes the joint between a foundation wall and adjacent stairs, which are subject to a lot of movement.

Mix ElastiPoxy with sand for a strong, permanent, and rigid repair of:

  1. CONCRETE SPALLING - Repair spalls, holes, and defects in concrete driveways, patios, and pool decks.
  2. CRACKS IN CONCRETE BLOCKS - Permanently seal cracks in concrete block or brick foundation walls.
  3. CRUMBLING CONCRETE - Use as a parging to repair and waterproof crumbling or honeycombed concrete.
  4. LEAKING BLOCKS - Parge very porous, deteriorated, or crumbling blocks to strengthen and waterproof.
  5. STRESS CRACKS - Use for filling very wide cracks in concrete floors.
  6. RUSTING STEEL – Fill holes caused by rusting embedded steel in parking decks and bridges after coating the steel with pure ElastiPoxy.
  7. FORM TIES - Waterproof leaking form wire ties in poured concrete walls.

APPEARANCE

Gray color. You can mix in a color pigment or use colored sand to match the surface color. Adding sand or sprinkling on sand before it cures makes the surface color and texture look more like concrete. The filler is partially paintable. When using pure epoxy, it is best to roughen up the surface first with a grinder.

Repair Kit Contents

  • 1 can of Base Resin (Compound A)
  • 1 can of Epoxy Hardener (Compound B)
  • 2 Measuring Cups
  • 2 Mixing Attachments

You will need a small plastic pail for mixing the two compounds and a low-speed electric drill for the mixers. If needed, get some DRY construction sand or play sand (with no fines!). A small plastic watering can or a cup with a spout for pouring pure epoxy into joints and cracks in floors or a small trowel for applying the epoxy-sand mix.
