Top 10 Best Epoxy Glue For Concrete

Quick repairs and assembly of 3D printed parts often call for a fast-setting, strong epoxy. When time is of the essence, a rapid-cure formula can make all the difference for DIYers and makers.

J-B Weld KwikWeld is a trusted solution for those needing a strong bond across a variety of surfaces, including plastics, metal, and wood. Its syringe design enables easy, mess-free mixing.

• 6-minute set time minimizes wait and speeds up projects
• 3127 PSI tensile strength for reliable, lasting bonds
• Works on multiple materials for broad DIY use

Compared to slower-curing or decorative resins, KwikWeld focuses on speed and strength. The tradeoff is a dark grey cure color, which may not suit visible or clear-finish needs.

When shoe repairs need to be strong but also nearly invisible, a clear, heavy-duty adhesive is the go-to solution. This is especially important for visible areas or lighter-colored footwear where glue marks would stand out.

GORILLA Max Strength Clear Adhesive offers a powerful bond with a crystal clear finish, making it ideal for those who want repairs to blend seamlessly. It's well-suited for both indoor and outdoor shoes, and for anyone who values a subtle, waterproof fix.

• 2x stronger formula: Delivers a robust bond for demanding repairs
• Crystal clear adhesive: Leaves minimal visible residue
• Paintable and gap-filling: Adapts to various shoe materials and repair needs

Unlike standard super glues, this adhesive prioritizes strength and invisibility. The main tradeoff is a slightly longer cure time for maximum durability.

Anchoring bolts or repairing structural cracks in concrete requires an adhesive that can withstand stress and environmental changes. A specialized epoxy paste ensures a secure, permanent hold in these demanding applications.

PC-Concrete Epoxy Paste is formulated for anchoring threaded rods, bolts, and dowels, as well as filling cracks in concrete and masonry. Its high-tack formula resists moisture and can be used in vertical or damp environments, making it suitable for both indoor and outdoor repairs.

• High-tack paste resists moisture and works on vertical surfaces
• 20-minute work time allows for careful placement and adjustment
• Wide temperature range supports use in varied conditions

Compared to general-purpose adhesives, this product prioritizes anchoring strength and crack filling. The tradeoff is a longer cure time and a more specialized application process.

Small 3D prints and minor repairs often require a reliable adhesive that dries clear and holds strong. For those working on quick fixes or reinforcing delicate parts, a versatile epoxy is essential.

GORILLA 2 Part Epoxy is a practical choice for home users who need a straightforward, gap-filling solution. Its easy-to-use syringe design makes it suitable for beginners and those tackling occasional repairs.

• 5-minute set time allows for repositioning and quick adjustments
• Gap-filling formula bonds uneven or vertical surfaces securely
• Water resistant for added durability in moderate conditions

Compared to larger resin kits, this epoxy prioritizes convenience and targeted use over volume. The main tradeoff is its limited suitability for large surface coatings or artistic finishes.

Frequent small repairs on concrete and other materials can quickly use up single-use adhesives. A convenient multi-pack ensures you always have a reliable epoxy on hand for household fixes.

This Gorilla 2 Part Epoxy 2-Pack provides the same clear, strong bond as the single version, but with double the supply. It's ideal for DIYers who regularly tackle minor repairs and want a consistent, easy-to-use product.

• Two syringes included for multiple projects or backup supply
• 5-minute set time offers quick results with time to adjust
• Dries clear for seamless, professional-looking repairs

Compared to standard construction adhesives, this product prioritizes strength and versatility for large or challenging repairs. The main tradeoff is a longer cure time and a more industrial formula.

Repairing overhead or vertical concrete surfaces can be tricky, as many adhesives tend to drip or sag. A non-sagging epoxy paste is essential for these challenging repairs, ensuring the adhesive stays in place until fully cured.

PC-Masonry Epoxy Paste is formulated for masonry repairs on both wet and dry surfaces, with a non-sagging consistency that works well on horizontal and overhead applications. It's suitable for both indoor and outdoor use, and can be painted or stained after curing.
