There are several ways to attach trim to brick without using nails. One option is to use adhesive caulking or liquid nails, which can be used in conjunction with clamps or tapcon hex-head screws. Alternatively, you could use plastic anchors and small trim screws or a powder-actuated nailer. If you're looking for a temporary solution, super glue and painter's tape can be used to attach trim to brick, which can then be easily removed.

What You'll Learn

Using liquid nails
When attaching trim to brick without nails, one option is to use Liquid Nails, a construction adhesive. This method is long-lasting and durable but requires patience and careful planning. Here is a step-by-step guide:
First, determine the placement of the trim on the brick surface. Mark the desired location with a measuring tape and a pencil, ensuring straight rows and allowing for any necessary gaps or grout. Brush and vacuum the bricks to remove any loose dust before gluing.
Next, apply a suitable amount of Liquid Nails adhesive to the brick surface. Follow the manufacturer's instructions for safety and proper application, as different adhesives have varying drying times and strengths. Consider using adhesive caulking for added sealing.
After applying the adhesive, carefully position the trim onto the brick, pressing and holding it firmly in place. Use clamps, sticks, or wedges to support the trim until the adhesive sets. If the mortar joints are too soft or the bricks are uneven, consider using additional support, such as drilling in a tapcon hex-head screw or shooting finish nails into the mortar.
For a seamless finish, fill any gaps or nail holes with colour-matched filler or wood filler, and lightly sand the area. If you need to remove the trim in the future, be aware that Liquid Nails can damage the wall, and you may need to replace the drywall or use paint and varnish remover, which requires elbow grease.

Tapcon screws
To use Tapcon screws, you will need to follow these steps:
- Determine the correct length of screw for your application. The minimum length is determined by adding 1 inch to the thickness of the material being fastened, and the maximum length is found by adding 1-3/4 inches to the thickness.
- Drill a hole into the brick using a hammer drill. Ensure that the hole is deep enough by adding 1/2 inch to the minimum and maximum depths mentioned above. Use the correct diameter carbide-tipped bit for the screw size you are using.
- Clean the hole of any dust and debris using a wire brush and vacuum. This step is crucial to achieving proper installation.
- You may also want to use some silicon caulk in the hole before installing the screw, as suggested by one source.
- Insert the screw through the fixture and into the pre-drilled hole. Use a #2 driver for a 3/16-inch screw and a #3 driver for a 1/4-inch screw.
- Be careful not to over-torque the Tapcon screw, as this may cause it to spin in the hole and lose its holding value. Turn the screw by hand for the last few revolutions to prevent this.

Adhesive caulking
For brickwork, it is recommended to use a caulk that dries clear. Silicone caulk or butyl-rubber caulk are suitable for outdoor areas as they can withstand exposure to various elements. If you are new to caulking, opt for a paintable silicone caulk that appears white when applied but dries clear.
Before starting your project, choose an inconspicuous spot to test the caulk. Hold the caulk gun at a 45-degree angle to the brick surface and release a small amount of caulk. Rub it into place and if you are satisfied with the appearance, you can begin caulking. Press the trigger of the caulk gun and spread a layer of caulk along the brick in a single motion. When you reach the end, release the trigger to stop the flow of caulk.
To create a smooth, professional finish, place your finger over one end of the caulk and press down slightly. Run your finger along the entire length of the caulk line, pushing it into small crevices. Once the caulk is completely dry, you can paint over it if needed.
In addition to caulking, liquid nails can be used as an adhesive to attach trim to brick. However, if you are concerned about damaging the brick, consider using a product specifically designed for brick, such as LePage PL Polyurethane Concrete Crack & Masonry Sealant. This sealant is flexible, expands with joints, and prevents stress cracks. It is also paintable and can match any surface.

Small right-angle brackets
When attaching trim to a brick wall, there are several methods that do not require the use of nails. One option is to use adhesive caulking or liquid nails along with trim-head screws. If the mortar joints are not too hard, you can also use Naze Harwood trim nails with adhesive. For a more removable option, consider keyhole mounts or wooden cleats, though these will require painting and maintenance.
If you want to avoid using nails altogether, small right-angle brackets can be an effective solution. Here is a step-by-step guide on how to use small right-angle brackets to attach trim to a brick wall without nails:
- Choose the appropriate size and material for your small right-angle brackets. They should be small enough to fit discreetly behind the trim and made of a durable material such as metal or plastic.
- Prepare the surface of the brick wall by cleaning and drying it to ensure that the brackets will adhere properly.
- Mark the locations for the brackets on the brick wall. Place the brackets at regular intervals along the top of the trim, spacing them according to the weight and length of the trim.
- Drill pilot holes into the brick at the marked locations. Use a masonry bit and adjust the torque setting on your drill to a low force, as small holes require less force.
- Insert anchor screws into the pilot holes. Make sure the anchors are secure and tight.
- Mount the right-angle brackets onto the anchor screws. The brackets should have holes that align with the screws, allowing you to screw them directly into the brick.
- Place the trim against the wall, aligning it with the top edge of the brackets.
- Secure the trim to the brackets using screws or other appropriate fasteners. Make sure the screws are tight enough to hold the trim firmly in place.
- If desired, you can fill and conceal the screw holes using matching plugs or decorative elements.
By following these steps, you can attach trim to a brick wall using small right-angle brackets without the need for nails. This method provides a secure and removable solution for decorative trim projects.

Plastic anchors
To use plastic anchors, start by drilling holes in the brick using a hammer drill and a masonry drill bit. The hole should be deep enough to accommodate the anchor and screw (if using one) and slightly larger than the anchor to ensure a snug fit. It is important to wear safety goggles and a dust mask to protect yourself from dust and debris during the drilling process.
After drilling, blow or vacuum out any dust from the holes. Then, insert the plastic anchors. If using screws, select ones that fit the anchors and are long enough to extend through the material being attached. Insert the screws into the anchors and tighten them securely.
When choosing plastic anchors, consider the weight of the object being attached and select an anchor with a suitable load capacity. For example, toggle bolts can typically handle loads between 30 and 50 pounds, while drop-in anchors are suitable for heavy-duty applications. Additionally, consider the environment and select anchors made from appropriate materials, such as nylon, plastic, or steel, which offer varying levels of durability and corrosion resistance.
