Installing Signs On a Wall or Building Side
There are a few things to consider when installing your signs on a wall. Two key factors are size and weight of the sign, and the type of wall you are attaching the sign to.
Installing Small Signs
For small signs on a very smooth surface wall, you can use double-sided foam tape. Apply the tape to back of the sign all around the edges in continuous strips as well as some additional strips in the center. Before you take the backing strips off, make sure you have marked where you are putting the sign. Use a level to ensure the sign is straight as you put one edge against the wall and slowly push the sign in place against the wall. Press all the edges firmly to ensure maximum adhesion.
Installing Medium Sized Signs and on Rough Surfaces
For larger signs (up to 24″ x 36″) or for rough wall surfaces, double-sided tape alone will not be enough to hold your sign securely in place. You also need a caulking gun with silicone or construction glue. Apply double-sided tape to the back of the sign along all the edges. You can also apply a few strips through the center of the sign.
Next, apply a generous amount of silicone or glue to the center of the sign. Put the bottom edge of the sign against the wall and, with your level along that edge, slowly push the sign in place and press it firmly and evenly to ensure it is secure.
With this method, the double-sided tape will hold your sign in place while the silicone sets up. This is also a much more secure sign installation method to prevent theft or vandalism of the sign.
Installing Large Signs
Up to 48″ x 96″ full sheet alupanel signs or other materials such as glass that are quite heavy require anchors. The type of anchor depends on the type of sign and wall material.
For thin alupanel signs on concrete walls, you can use drive rivets. Pre-drill 3/8″ holes through your sign. Hold the sign in place on the wall and use a concrete drill to make a 1″ deep hole for a rivet at the top center of the sign. Insert your drive rivet and hammer it in place with a hammer.
This first rivet will hold your sign in place while you make sure it is level and drill the rest of your holes into the concrete and apply rivets as you go.
For drywall walls, use drywall anchors instead of drive rivets.
Installing Signs on Garage Gates
Garage gate pickets are hollow to keep the weight low so the electric operator can lift the gate. Signs can be installed using self tapping screws or bolts right through the gate pickets to secure the sign.
The sign size and placement should fit within the height of a single panel. Each panel has hinges across it allowing the gate to bend as it rolls up when opening. If your sign must be higher than the height of a single panel, it should be divided into separate signs that fit within each panel.
Installing Signs with Sign Posts
If you want to install a sign post in the ground with concrete, instead of using a surface mounted sign base, you can use the following procedure:
- Cut through asphalt or concrete if required using a concrete saw. Concrete sidewalks are typically at least 4″ thick and asphalt is typically 2″ to 3″ inches thick. Your hole should be 16″ x 16″ square.
- Dig out your 16″ x 16″ wide hole to a depth of 24″ (2 feet).
- Insert your sign post in the hole. Make sure it is vertically straight using a level on the side of the post and ensure it is facing the right direction.
- Use ready mix concrete and make up a batch in a wheelbarrow according to the instructions on the bag. Shovel it into the hole while someone ensures the post is centered and straight.
- Pack the concrete down and fill until the hole is full to the top. When installing your sign in a grassy area, leave a couple inches from the top free for grass to grow over the concrete. For concrete and asphalt surfaces, make the concrete level with the surrounding surface and smooth the top using a trowel.
