Gorilla Max Strength Construction Adhesive (Clear)
The Gorilla Max Strength Construction Adhesive is designed for heavy-duty bonding with a crystal-clear finish that helps keep brickwork looking clean. It is positioned as stronger than Gorilla’s standard Heavy Duty line, offering a robust solution for masonry gaps and joint repairs where visibility matters. The formula is waterproof and suitable for indoor or outdoor projects, delivering a strong bond even in damp or submerged conditions. The product is versatile for most masonry repairs where a discreet, durable adhesive is needed.
- 2x strength compared with Gorilla Heavy Duty Ultimate in relevant tests
- Crystal-clear finish preserves the appearance of brick joints
- Waterproof and suitable for indoor or outdoor use, including wet conditions
Gorilla Heavy Duty Construction Adhesive (7 Oz)
This 7-ounce white construction adhesive is designed for a broad range of projects, including masonry work on bricks. It provides a strong, waterproof bond and is meant for both interior and exterior applications. With quick grab, it can hold materials in place rapidly, aiding alignment before the adhesive sets. The formula is paintable, letting you finish brick surfaces with ease to match surrounding textures or finishes.
- Waterproof bond suitable for brick and masonry
- Fast grab, typically setting in seconds to minutes depending on conditions
- Paintable on many surfaces for a seamless finish
Gorilla Heavy Duty Construction Adhesive (9 Oz)
The 9-ounce cartridge version of Gorilla’s heavy-duty line provides a durable, waterproof bond for brick and masonry projects. It shares the fast-grab characteristics that help with efficient installation and reduction of project downtime. As with other Gorilla heavy-duty formulations, it is designed to perform on multiple substrates, including brick, stone, concrete, and wood, with a finish that can be painted to suit the project aesthetic.
- Heavy-duty, waterproof performance on brick and masonry
- Fast grab for quick positioning and setting
- Paintable for flexible finishing options
Gorilla Original Gorilla Glue (2 Oz)
The original Gorilla Glue is a waterproof polyurethane formula known for its versatility across dissimilar surfaces. It performs well on brick and other masonry materials, offering a strong, durable bond that resists outdoor elements. It is particularly valued for tough repairs where substrates differ, such as brick to concrete or brick to metal. The glue expands slightly during curing, so surface preparation and clamping can enhance final results.
- Leading multi-purpose, waterproof polyurethane glue
- Excellent for bricks, stone, and other masonry
- Strong outdoor performance on varied substrates
Flex Glue Mini White (0.75 Fl Oz)
Flex Glue Mini White is a rubberized, waterproof adhesive designed for quick and flexible bonds. Its ability to work on dry or wet surfaces, including underwater, makes it appealing for brickwork in damp environments or where masonry joints may experience moisture. It provides strong initial grab and a durable bond with relatively simple application, making it a practical option for small brick repairs, paver work, and masonry touch-ups.
- Works on dry, wet, and underwater surfaces
- Strong instant grab with flexible, durable bond
- Compact, portable tube ideal for small brick tasks
Buying Guide
Choosing the right brick glue depends on the specifics of your project, including surface texture, exposure, and required finish. The following considerations help compare options and optimize results for brickwork.
- Bond type and substrate: Porous bricks benefit from adhesives formulated for masonry; polyurethane glues work well on uneven surfaces, while CA glues (cyanoacrylate) are best for small, fast repairs on clean joints. For structural masonry, consider heavy-duty construction adhesives or polyurethane formulas designed for exterior use.
- Water exposure and weather resistance: Exterior brickwork or damp environments require waterproof adhesives with proven moisture resistance. Some sprays and CA glues may not perform well under constant moisture; select products labeled waterproof or weatherproof for long-term durability.
- Open time and cure speed: If you need quick positioning, fast-grab adhesives reduce setup time. For larger bricks or complex shapes, slower-curing formulations or those allowing clamp time can improve alignment and bond strength.
- Viscosity and gap filling: Thick or high-viscosity glues fill larger gaps and resist sagging on vertical joints. Thinner adhesives spread easily but may require gap planning or surface preparation to avoid runs.
- Finish and paintability: If the brick appearance matters, choose clear or paintable adhesives that won’t disrupt the aesthetic. White or brown formulations can affect the look of mortar joints or brick faces unless covered or painted.
- Application environment and safety: Outdoor projects demand UV stability and outdoor durability. Interior projects may prioritize ease of cleanup and minimal odor. Always follow safety instructions, use gloves, and ensure proper ventilation when using solvent-based products.
- Surface preparation: Clean, dry surfaces bond best. Remove dust and loose mortar, pre-wet where appropriate (for some adhesives) and clamp or weight pieces during curing to maximize adhesion.
- Brand and warranty considerations: Reputable brands with masonry-specific claims often provide more reliable performance. Check product data sheets for cure times, substrate approvals, and warranty guidelines to match your project needs.
When selecting a glue for bricks, align the product’s properties with your project’s demands: whether you need a nearly invisible, waterproof joint, a fast-setting bond for interior brick veneer, or an adhesive capable of withstanding outdoor exposure. The five options highlighted here cover a range of common brick applications, helping you choose based on bond strength, finish, and curing behavior. Always test a small area first to confirm compatibility with your brick, mortar, and any coatings or paints you plan to apply.
