Crack Repair Kits for Concrete & Masonry

"Magic crack filler" often refers to low-viscosity adhesive systems that flow into cracks by capillary action. Tech-Bond Global's SI Green ultra-thin formula functions on this principle — it penetrates hairline cracks at the molecular level and cross-links the surfaces together, creating a bond that is permanent and structurally stronger than a surface-applied filler or epoxy.

Choose SI Blue for standard, general-purpose bonding tasks. Use SI Black (thick viscosity) when you need greater control, such as overhead applications or detail work. Select SI Green (ultra-thin) specifically for hairline crack repair where penetration depth is critical. All kits include viscosity selection guidance on the product page.

Yes. Tech-Bond Global's patented Polymer Bonding Process is specifically engineered to bond historically unbondable materials including PTFE (Teflon), HDPE, Delrin (POM), polypropylene, and silicone rubber. The Deluxe and Professional Kits include Poly Prep surface preparation, which activates these surfaces for true molecular cross-linking rather than simple adhesion.

All Tech-Bond Global bonding kits feature an extended shelf life when stored in a refrigerator. After opening, bring the bonding agent back to room temperature before use. Refrigerated storage is strongly recommended to maximize usability across the product's full lifespan, particularly important for bulk or commercial buyers holding inventory.

Yes. The Tech Patch and Tech Wrap Kits are purpose-built for field repair of metal pipes, metal tanks, and PVC pipes. Available in seven widths from 2" to 12", they are part of the Tech Patch Repair System (TPRS) — the only system globally proven to repair HDPE pipe, including a successful repair on a 78-inch HDPE pipe for Borouge in Abu Dhabi.

Tech-Bond Global kits serve a wide range of industries including pipeline and tank maintenance, mining, solar and wind energy, marine, automotive, HVAC, plumbing, agricultural equipment, and more. Dedicated Industry Kits are also available for specialized sectors such as taxidermy, funeral prep rooms, and solar panel applications, each configured for sector-specific bonding challenges.
