UPPERCASE VERSUS LOWERCASE LETTERS

typography alphabet

The font has been carefully designed to allow a viewer's eye to easily see the shape of each character. Not each character in a font is exactly the same size; otherwise your sign lettering would be difficult to read. We name the font after its uppercase letter 'A' size but most lowercase letters are shorter. Some lowercase letter shapes such as 'b d f h k l' have ascenders which can be taller than the uppercase 'A' height. Some lowercase letters such as 'g j p q y' have descenders which go below the words baseline. Uppercase letters that are rounded such as 'C G J O Q S U' are taller than an uppercase 'A' because the rounded part extends above and below the baseline. Please call us if you need to know the character's actual size and not its named size.

INSTALLATION OF BUILDING SIGN LETTERS
SO SIMPLE THEY'D THOUGHT A PRO DID IT!

Christy will take you step-by-step through the process of installing building letters. Thoroughly clean application area of all dirt, tar, and wax. Mark the decal with a ruled line along the top of letters and down its center.

Stud Mount Method

  • 01
    install step one

    Tape one edge of the template to the installation surface and unroll it. Level the template and tape the other edge of the installation surface.

  • 02
    install step two

    Mark holes with center punch, then drill 1/4" holes 3" deep where indicated on your template. Remove the template and clean out all drill holes using any of the following methods: a quick puff of air, using the vents on your drill, compresses air or a turkey baster.

  • 03
    install step three

    Insert the studs into the stud holes on the back of each letter. Place letters in holes on wall before applying silicone to verify position. Adjust as necessary. Now fill the drill holes in the wall of the first letter with silicone.

  • 04
    install step

    Push the tube of silicone over each stud on the first letter in order to evenly coat it with adhesive.

  • 05
    install step five

    Push the letter into the drill holes using a shim or spacer to assure proper stand off of the letter from the wall. Repeat steps 2 through 4 for the rest of the letters.

Pad Mount Method

  • 01
    install step one

    Clean the installation surface firs. Position the spacing tape on the wall and secure one end with masking tape. Unroll, level and tape the other end. Spacing tapes show the general position of each letter.

  • 02
    install step two

    Apply silicone to all the pads on the letter first. Position the letter on the wall where indicated with the spacing tape. Tape the letter to the wall with several strips of masking tape.

  • 03
    install step three

    Adjust as needed, push letter against wall to ensure good adhesive bond. Continue with the remainder of the letters, and allow the silicone to cure before removing the masking tape. Temperature and humidity will influence silicone cure times. On some conditions letters should cure overnight.
