The Sure Set Process

Check the weather. It’s best if its between 40 and 90 degrees Fahrenheit.

Unpack and lay out your numbers to rest and flatten.

Gather these tools: 

Masking tape (included)
Squeegee (included)
Dry erase marker (included)
Tape measure
Step stool/ ladder
Isopropyl alcohol (for window cleaning)
Application fluid (included)
Position your step ladder so you are eye level with the glass – ensure good clean lighting so you can see what you are doing.


Clean your window – wash and rinse with water and a dab of dish-soap. Dry with lint free towel. Finish the cleaning with isopropyl alcohol and lint free cloth. Wipe in one direction. No lint.

Mark the vertical center and horizontal level with the dry erase marker (do on outside of window if doing interior installation).

Temporarily tape the number up on the inside of the glass, aligning the center and level marks. Check for position. Adjust as necessary.


    Installing the number


    1.       Place a tape hinge along the bottom of the numbers and tape them in place on the glass.

    2.    With the hinge holding the numbers, let them fall back so you can remove the plastic backing paper.

    3.    Carefully remove the clear plastic backing paper. If any of the numbers stick to it, simply lay the plastic back down and press your squeegee against that area and try again. Take your time.

    4.       With the numbers now exposed, spray the application fluid onto the glass and also onto the numbers. Be generous.

    5.       Lay the numbers up against the glass, adjust if needed, and gently squeegee out the application fluid.

    6.    Now spray the back of the numbers with more application fluid. This helps to release the paper once the adhesive has set.

    7.    Wait an hour and then begin pulling the paper backing away from the window. Using a sharp angle as shown in the photo helps to reduce the pull on the digits.


    8.       If any part of the number begins to pull away simply squeegee it against the glass and wait another 10 min.

    9.    Once the numbers are up, use a soft lint free cloth to clean off any application fluid that may be on the glass.


     Installing the shade


    1.       To begin, lay your shade face down on a clean flat surface and squeegee the back of it. Push firmly.

    2.    Flip the numbers over and gently remove the plastic backing paper.

    3.    IMPORTANT:  Keep track of the side of the plastic that is against the numbers as you are going to reapply the plastic in the next step.

    4.    Reposition the plastic with the shiny side against the numbers while leaving the registration marks exposed (see the photo).

    5.     Carefully align the shade’s registration marks over top of the ones that have already been installed on the glass.  Once aligned, squeegee it against the glass firmly. This will now serve as a hinge for the installation.

    6.       Let the numbers fall back, and gently peel away the plastic backing paper starting from the bottom left (as shown in the photo).

    7.    From the bottom up, squeegee the numbers against the glass. Once it is on the glass, continue to squeegee it.

    8.    Peel the application tape away using a sharp angle as shown in the photo.

    9.    For a tight appearance, run your finger around the area where the shade and the number meet.

    10.  If you have any air bubbles you can pop them from behind with a pin and squeeze the air out.  

    11. Remove the registration marks, clean the glass front and back and enjoy your new house numbers.
