ElastiPoxy Control Joint Sealant and Crack Filler Kit

When Caulk and Rubberized Sealants Fail, Use ElastiPoxy

ElastiPoxy is a two-component, self-leveling, 100% solids, semi-rigid, epoxy control joint sealant and concrete crack filler. Used to repair and protect contraction/control joints, saw cuts, floor-to-wall joints, mortar joints, and large cracks in concrete floors and concrete blocks. An advanced formula that features an extended pot life and workability that allows for hand-mixing and pouring.

Once cured, ElastiPoxy is virtually indestructible! Impervious to water and soils gases with excellent chemical resistance. Strong enough to prevent damage or deterioration to joint shoulders caused by hard-wheeled carts or heavy vehicle load, while flexible enough to tolerate natural movements in the crack or joint. When mixed with dry construction sand, ElastiPoxy behaves more like a super-strong and super-durable patching mortar to provide a rigid repair for large voids and defects in both vertical and horizontal surfaces.

• Easy to Use – 1:1 mix ratio makes preparing and using ElastiPoxy easy. The complete kit includes paddle mixers and measuring cups.
• Incredibly Versatile – Use straight for a flexible repair on horizontal surfaces. Modify with sand for a rigid repair and for use on vertical surfaces.
• Flexible – Allows for the natural expansion and contraction of concrete.
• Moisture Tolerant –  Able to adhere to damp surfaces making it ideal for use in subterranean applications and slab-on-grade construction; basements, garage slabs, warehouses, and elevator pits.
• Zero VOCs – Safe for use indoors and in basements. Can help comply with LEED certification.

Amateur ‘Fixes” for Cracks and Control Joints in Concrete Slabs and Walls

Polyurethane Caulk & Rubberized Sealants – The most commonly mis-used concrete crack filler because of their ease of use, availability, and cost. A masonry caulk will bond well to dry concrete, but over time wicking water, efflorescence, ice, vehicular traffic, shoveling, and plowing will gradually weaken the bond. Caulk and rubberized products offer no strength and will shrink causing it to separate from the concrete. Soon enough, you will need to remove the material and repair the joint again.

Hydraulic Cement & Concrete Patching Compounds –  Hydraulic cement will fill and waterproof the joint, but concrete does not bond well to itself. It is the reason why when using a concrete patching compound, an inverted V-groove is required before filling. Hydraulic cement is rigid! More so than concrete and does not flex as the concrete expands/contracts. Making it unsuitable for use in moving joints. It will not be long until this rigid rod loosens and separates, exposing efflorescence around water leaks around the edges. Read more about why hydraulic cement is a poor crack repair material. 

These common methods provide only a superficial and temporary fix. Using ElastiPoxy provides a stronger, longer-lasting, practically permanent solution for flexible control joints, floor-to-wall joints, and saw cuts in slabs. Alternatively, when mixed with sand, a supreme rigid repair for cracks in concrete block walls, garage slabs, basement floors, parking lots, and commercial sidewalks.
