Top Picks: Best Glue For Brick
If you’re looking for the best glue for brick, you’re in the right place. Whether you’re working on a DIY project or repairing some broken bricks, using the right adhesive is crucial for a long-lasting and secure bond. In this article, we’ll discuss the top two glues for brick, highlighting their features and benefits, so you can make an informed decision.
Loctite PL Premium Polyurethane Construction Adhesive: Features And Benefits
Loctite PL Premium is a heavy-duty polyurethane construction adhesive that’s a solid general-purpose pick for bonding solid bricks together. Here are its key features:
- Cartridge application: dispensed from a standard caulk gun cartridge for controlled, even beads along the joint.
- Fast-tacking formula: forms an initial bond quickly, though full cure takes longer like most polyurethanes.
- Waterproof once cured: resistant to water, making it suitable for both indoor and outdoor brick applications.
- Weather resistant: holds up across a wide temperature range once fully cured.
- Versatile: bonds brick to a range of other materials including stone, concrete, and wood.
- Strong, rigid bond: not the right choice for a memorial or monument repair (see below) since it doesn’t flex with temperature swings the way stone conservation epoxy does.
PC-Masonry Two-Part Epoxy: Features And Benefits
If you’re repairing broken or damaged brick or stone rather than building something new, this two-part epoxy is a better fit than a general construction adhesive. Key features:
- High adhesion: bonds tightly to brick and stone surfaces for a long-lasting repair.
- Semi-flexible cure: moves slightly with the material rather than staying perfectly rigid, reducing the chance of a repaired joint cracking again later.
- Heat resistant: holds up in applications where the brick is exposed to higher temperatures.
- Chemical resistant: the cured bond resists most common chemicals and cleaning products.
- Two-part mixing required: unlike a single-tube adhesive, needs the resin and hardener combined before application, so read the working-time window before starting.
Between the two, the deciding factor is the job: use the polyurethane construction adhesive for general brick-to-brick bonding, and reach for the two-part epoxy specifically when repairing a crack or break in existing brick or stone, including projects where a strong, lasting repair matters.
Tips For Proper Application And Bonding
When it comes to using the best glue for bricks, proper application and bonding techniques are essential to ensure a long-lasting and durable bond. To help you achieve optimal results, we have compiled a list of tips that will guide you through the process. From surface preparation to application techniques, follow these guidelines to ensure your glue adheres firmly to the brick surface.
Surface Preparation
Before you begin applying the glue, it is crucial to prepare the brick surface properly. This will ensure better adhesion and a stronger bond. Here are some steps to follow:
- Clean the surface: Remove any dirt, dust, or debris from the brick surface using a stiff brush or a damp cloth. This will create a clean and smooth surface for the glue to adhere to.
- Remove loose or damaged material: Inspect the brick for any loose or damaged areas. Use a chisel or scraper to remove these areas, ensuring a solid and stable surface for bonding.
- Etch the surface: Depending on the type of glue you are using, you may need to etch the brick surface to enhance adhesion. Follow the manufacturer’s instructions for etching, if required.
Application Techniques For Optimal Bonding
Once the surface is prepared, it’s time to apply the glue and ensure optimal bonding. Here are some techniques to keep in mind:
- Apply the glue evenly: Using a caulking gun or a trowel, apply the glue evenly on the surface. Avoid applying too much or too little glue, as it can affect the bonding strength.
- Spread the glue: After applying the glue, use a putty knife or a roller to spread it evenly across the brick surface. This will ensure maximum contact between the glue and the bricks.
- Press and hold: Once the glue is spread, press the bricks firmly together and hold them in place for the recommended curing time. This will allow the glue to bond effectively and create a strong connection.
- Use clamps or supports: For larger or heavier brick structures, consider using clamps or supports to hold the bricks in place until the glue sets completely. This will prevent any shifting or movement that may weaken the bond.

Frequently Asked Questions On Best Glue For Brick
What Is The Best Glue For Brick?
The best glue for brick is an epoxy adhesive, specifically designed for heavy-duty bonding. It creates a strong and durable bond that can withstand extreme temperatures and weather conditions. Look for a glue that is waterproof, weatherproof, and resistant to chemicals for optimal results.
Repairing A Broken Memorial Or Headstone Brick (This Is Different From Regular Brick Repair)
Repairing a broken memorial, headstone, or grave marker brick is not a job for regular construction adhesive, silicone, or caulk. Conservation guidance is specific here: use a conservation-grade, semi-flexible epoxy made for stone and monument repair, not a rigid all-purpose adhesive. Stone and brick monuments expand and contract with temperature swings, and a rigid glue will eventually crack and separate at the joint — a semi-flexible epoxy moves with the material instead of fighting it.
Before applying anything, clean the broken surfaces thoroughly and let them dry completely; epoxy bonds fail on damp stone. Gently wire-brush the break edges to remove loose dirt and old adhesive residue, then apply the epoxy per the product’s instructions. Never use household glue, silicone, caulk, or packaged concrete patch on a memorial repair — these trap moisture against the stone and typically cause more damage over time than the original break.
Applying Thin Brick Veneer To Drywall (A Different Adhesive Than Regular Brick)
If you’re applying thin brick veneer to an interior drywall wall rather than bonding solid bricks together, skip the construction adhesive and epoxy discussed above — that’s built for structural brick-to-brick bonds, not for face-mounting thin veneer tiles. Use a mastic or thin-set mortar adhesive instead, applied with a notched trowel at roughly 3/8″ thickness, mixed to a consistency similar to creamy peanut butter. Back-butter each piece for extra adhesion, and let it cure 24-48 hours before grouting the joints.
