ElastiPoxy Joint Sealant & Crack Filler

ElastiPoxy is a unique, state-of-the-art joint sealant and crack filler for concrete and masonry repairs. Unique features:

• Adequate elongation to allow for the natural movement of concrete or masonry
• Adhesion to damp surfaces, making it ideal for basements, slabs on grade, and driveways
• Environment-friendly, zero VOCs.

ElastiPoxy is a two-component flexible epoxy. No polymer additives, 100% solids, zero VOCs. Low viscosity, self-leveling epoxy for filling joints, cracks, and spalls in slabs. Impact-resistant. Virtually indestructible under high water pressure or heavy traffic. Good chemical and water resistance. When mixed with sand, provides a strong, rigid filler for filling cracks or defects in masonry walls.

Use pure, self-leveling ElastiPoxy for repairs of concrete slabs as:

1. Elastomeric joint sealant for factory floors and driveways to protect edges against heavy wheel loadings.
2. Expansion joint filler for foundation slabs and basement floors to allow for the natural movement of concrete slabs.
3. Floor-to-wall joint sealant in basements and buildings to seal against water vapor and radon gas.
4. Crack filler for concrete floors – route out the crack first 1/2" deep.
5. Filler for holes in parking decks and coating of embedded steel.
6. Filler for pit marks in slabs, indoors or outdoors.

Mix ElastiPoxy with sand for a strong but rigid repair of:

1. Cracks in concrete blocks or brick walls – route out first with a grinder or chisel hammer.
2. Spalls, pits, holes, and defects in concrete driveways, patios, and pool decks.
3. Large cracks in concrete or masonry floors and walls.
4. Lightweight and split face blocks, or other blocks with little or no cement.
5. Very porous or crumbling blocks and concrete - trowel the epoxy-sand mix into the surface.
6. Leaking form ties in poured concrete walls.

The Old Ways of Fixing Cracks

These common methods provide only a superficial and temporary fix.

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.

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.

Do-It-Yourself Elastic Epoxy Crack Filler Kit

The ElastiPoxy joint and crack repair kit is suitable for both contractors and homeowners.

Contents of the Kit:

1 can of Base Resin (compound A)

1 can of Epoxy Hardener (compound B)

2 measuring cups

2 mixer attachments.

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

Appearance: Gray 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.

Coverage

Based on a routed out crack 1/4" wide by 1/2" deep and using pure epoxy (without added sand), the smaller kit (2 quarts of epoxy) will fill approximately 75 linear feet. The larger kit (2 gallons of epoxy) provides four times more volume – 300 linear ft.

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