PrezisionCut® Dry/Hinge Installation Instructions


Please thoroughly and carefully read these instructions — failure to do so may result in permanent damage to your decal.


Installing a large vinyl decal is not as simple as “peel and stick.” Many variables can cause damage to your decal before, during, and after installation. Understanding how our decals are made and what variables can affect the decal will significantly improve your installation experience. 


Please watch our installation demonstration video for a visual reference of the instructions below. The video is not a complete step-by-step guide. We strongly recommend that you review these written installation instructions as they explain in detail the many variables that may affect your installation.

Your decal will arrive rolled-up, face-out inside our 100% recyclable shipping tube. Please contact us immediately if your package is delivered damaged. After inspection, we highly recommend that you roll the decal face-out (just like it was shipped) inside the shipping tube until the day of installation. This will help keep the transfer tape from delaminating. Always store the decal out of direct sunlight in a cool, dry, climate-controlled area until the day of installation.


We highly recommend hiring a professional to install your decal. Most tint, sign, or wrap companies will install our decals for a fee. A professional will have the experience, additional tools, and a climate-controlled area to complete the installation. Please ask them to review these instructions before installation.

If you have any questions, please don't hesitate to contact us.

Installation Methods

We recommend two methods of installation: the Wet Installation method and the Dry/Hinge Installation method. Determining which method to use will depend on your confidence/experience level and environmental conditions.


Wet Method

The wet installation takes the most time to complete (up to 12 hours). However, it allows you to reposition and reapply the decal during installation, making it great for beginners. The temperature, humidity, and amount of application fluid used will determine the required amount of dry time. We recommend purchasing a decal with our opaque paper transfer tape if you plan on using this method. 


Dry/Hinge Method

The dry/hinge installation is the fastest method to install decals (average 20-90 minute installation times). However, unlike the wet method, you only have one attempt to get it positioned and installed. Once the decal touches the window surface, it cannot be removed without causing permanent damage.

Decal Construction

Our decals are constructed in three layers: (1) Release Liner: The release liner is a white (or blue if you order white vinyl) silicone-coated paper that protects the adhesive side of the decal during production, shipping, and installation. The release liner will be removed, either in whole or in part, during the installation and discarded, (2) Vinyl Material (Decal): The vinyl material (the actual decal) is sandwiched between the release liner and transfer tape and has a specially formulated clear, solvent-based adhesive coated on the back of the material, and (3) Transfer Tape: The transfer tape is a transparent vinyl or an opaque paper material with a medium-tack adhesive coating designed to adhere to the decal and keep the design together in one piece during installation. Once the decal is installed the transfer tape will be removed and discarded.

Environmental Conditions

Many environmental factors can affect the decal before, during, and after installation, including the installation location, air temperature, window temperature, humidity level, wind, and window cleanliness.


Although we recommend installing the decal in an enclosed, climate-controlled environment (e.g., a garage or shop), the installation may be completed outside. If you are performing the installation outside, you want to choose a location out of direct sunlight and free from airborne contaminants (e.g., under a tree that sheds leaves/cotton or in the middle of a dirt field). 


The ideal air temperature and window temperature are between 60°F and 80°F. Temperatures above 80°F may cause the adhesive to become incredibly tacky and can warp the transfer tape and vinyl, making installation difficult. Temperatures below 60°F will cause the adhesive to lose its adhesive properties, causing the decal to not adhere to the window. 


The humidity level, combined with the air temperature, will determine the drying time required for the wet installation method. If the humidity is high and temperatures are low, dry times will be longer. The dry/hinge method is typically not affected by humidity. 


We do not recommend installing the decal while it is windy. You will not only be exposing the adhesive side of the vinyl to the open air, but you will also be holding part of the decal with one hand and performing the installation with the other (unless you have someone assisting you). 


Inadequate or incorrect cleaning is the number one cause of decal failure. Make sure you thoroughly clean the window with a non-residue, oil-free and ammonia-free glass cleaner. If there are stubborn contaminants, use a small amount of denatured alcohol (rubbing alcohol works too). You may also use a square-edge razor blade scraper to remove contaminants like tree sap, or tar — just be extremely careful not to scratch your window. Waxes, polishes, ceramic coats, or other vehicle treatments must be thoroughly removed from the surface of the window.

Tools & Supplies


Glass Cleaner

It is used to clean and prepare the window surface before installation. Use non-residue, oil-free, and ammonia-free glass cleaners only.


Clean, Lint-Free Paper Towels or Microfiber Cloths

It is used to clean the window and soak-up excess application fluid from around the outside of the decal during installation. 


Denatured Alcohol (Rubbing Alcohol)

It is used to clean stubborn contaminants from the window surface before installation.


Masking Tape

Used to help hold the decal in various places during installation. Any generic masking tape will work. 


Scissors/Razor Blade

It is used to trim excess release liner/transfer tape from around the outside edge of the decal (if desired).



Find someone who can help you hold the decal and grab supplies during installation.


We recommend starting the dry/hinge installation method in the early morning or late evening, out of direct sunlight. If you are performing the installation outside, check the weather to ensure no chance of rain, snow, or high winds are forecast for the day of and day after you plan to complete the installation. 


The ideal air and window surface temperatures are between 60°F and 80°F. Temperatures above 80°F may cause the adhesive to become incredibly tacky and can warp the transfer tape and vinyl material. Temperatures below 60°F can weaken the adhesive coatings, causing the decal to not adhere to the window.

If you are completing the installation outside, only work on one decal at a time. Leave any additional decals inside a climate-controlled area and out of direct sunlight. Leaving the decal exposed to low/high temperatures or direct sunlight before installation may cause the transfer tape and vinyl material to delaminate and warp.


If you purchased a set of decals (driver and passenger side), follow these steps individually for each decal:


Step 1

Un-box and unroll the decal inside a climate-controlled area and lay it face-up on a smooth, flat, clean surface. Using the squeegee at a 45° angle with moderate pressure, start in the center of the decal and squeegee towards the outside edges of the decal. This will help re-adhere any areas of the transfer tape that may have become delaminated from the decal.


Optional: Trim the excess release liner and transfer tape from around the outside edge of the decal. 


Step 2

Bring the decal to the vehicle and position it face-out on the window. Align the decal to the window — keep in mind that it has been designed with a ⅛” offset from the outside edge of the window. In other words, the decal is ⅛” smaller than the actual window. Some decals come with installation guides (⅛” vinyl lines that follow the shape of the window) which will be removed after installation. 


Use masking tape to hold the decal in place at all four corners. Once you have the decal lined up to the window, run one single piece of masking tape vertically across the center of the decal and onto the vehicle at both ends — this will create the “hinge.” 


Step 3

Remove all pieces of masking tape from one side of the hinge — do not remove the hinge piece of masking tape. Start slowly and gently removing the transfer tape from one half of the decal. If there is a section or piece of the decal that remains on the release liner, slowly roll the transfer tape back over the section/piece and use the squeegee to adhere it to the transfer tape. If the decal remains adhered to the transfer tape, continue slowly removing the transfer tape. Continue this process until you reach the hinge. 


Be very careful not to touch the adhesive side of the vinyl decal to anything. 


Step 4

Cut the release liner with scissors just to the side of the hinge and discard. Fold the exposed side of the decal back over, keeping the decal completely off the window. With the other hand, use the squeegee at a 45° angle and begin working the decal onto the window starting at the center of the decal and moving vertically from center-out. Use moderate to firm pressure and work in small sections until you reach the far side and the decal is completely adhered to the window. 


Remove the remaining pieces of masking tape, including the hinge piece. The transfer tape will hold the decal in place. 


Repeat steps 3 and 4 for the remaining side of the decal.


Step 5

Run the squeegee, starting from the center and working towards the outside of the decal, across the entire decal to ensure you have adhered the decal to the window. 


Step 6

Starting in one corner, slowly and gently start peeling the transfer tape from the decal. If there is a section or piece of decal that remains on the transfer tape, slowly roll the transfer tape back over the section/piece and use the squeegee to adhere it to the window. If the decal remains adhered to the window, continue slowly removing the transfer tape until it is completely removed. 


Step 7

Your installation is now complete. Please allow at least 72 hours before washing your vehicle.

Care & Maintenance

Air Bubbles

Tiny air bubbles are expected (especially with the dry/hinge method) but don’t worry; they will dissipate on their own over a few weeks. If they do not dissipate or are larger than 1/4” in diameter, you can use a pinhead to poke a tiny hole in the center of the bubble and work the air out.


Cleaning the Decal

Cleaning your decal is easy and prolongs their life expectancy when done correctly. We recommend cleaning your decal each time you wash your vehicle or when there is a build-up of dirt or contaminants around the vinyl material. 


Using clean, dry, lint-free paper towels and ammonia-free glass cleaner, lightly mist the decal/window with the glass cleaner and carefully wipe the surface with a paper towel — being cautious around the vinyl edges. Use another clean and dry piece of paper towel to absorb any remaining moisture. 


Besides ammonia-free glass cleaner, mild dish soap, or mild car wash soap on or near the decal, do not use any chemicals or cleaners. Although possible, most commercial car washes and residential pressure washers will not damage your decal. We do not recommend using extreme high-pressure or high-temperature pressure washers or automatic touch car washes as they may reduce the life expectancy and permanently damage the decal.  


Please note that small elements within a design are more susceptible

to damage than larger areas and may fall off over time. 


Maintaining the Decal

Although vinyl is a resilient material, it can fail due to various reasons. However, most failures are small and can be easily repaired at home. Most of our decals are intricate and contain small, sharp vinyl edges. These areas of the design are considered weak spots and are the most likely to fail. 


If you notice a piece of vinyl that is beginning to peel, use an Exacto-knife to trim it — but be careful not to scratch your window. For large areas that have failed, we encourage you to use your imagination and trim the vinyl in a way that compliments the design.
