## How to Make Your Own DIY Window Film Application Solution

November 11, 2026

![image1-Nov-10-2026-05-38-22-3301-PM](https://blog.digitalwindowgraphics.com/hs-fs/hubfs/image1-Nov-10-2026-05-38-22-3301-PM.jpg?width=1999&height=1333&name=image1-Nov-10-2026-05-38-22-3301-PM.jpg)

When it comes to the production of window film graphics, the installer is the anchor of the team. All of the work and planning has led up to installation, when the graphic and messaging it projects will be shared with the world. With everything riding on the output of the installation, you’ll want to make sure you have a good installation process ready. And that includes having the right tools.

Depending on the material you are using, you may need to utilize an application solution. This can help the film material adhere to the glass and then set in place. While you can certainly purchase an off-the-shelf solution, you can also make your own.

Let’s see how even an amateur DIYer can make a lasting window film application solution.

## **Making Your Own Window Film Application Solution**

It is important to note that this solution should ONLY be used for wet-apply window films. If your window graphic is on a dry-apply adhesive film or a dry-apply cling, you will need to follow the installation processes specified for those window film material types.

### **Step 1: Gather the materials**

You’re going to need the “ingredients” for the solution as well as a way to apply it. That’s why you’ll want to have on hand:

- A clean spray bottle (32 oz. standard size)
- A squeegee
- 1 qt (32oz.) of purified water
- ½ capful (4-6 drops) of baby shampoo

**Substitutions:**

- If you don’t have baby shampoo, you can substitute Dawn dish soap (The original, blue formulation)
- You can use 1qt. (32oz.) of distilled water in place of purified.

### **Step 2: Mix the ingredients**

1. Open the water jug
2. Add in the ½ capful of baby shampoo (or Dawn)
3. Mix in place

After mixing, transfer to the spray bottle. Set the rest aside for future use.

| Pro Tip: Wait until the spray bottle is completely empty before refilling. Re-mix solution before pouring it into the spray bottle. |

### **Step 3: Applying the solution**

Now’s the time to put your DIY window film application solution into action. Use the spray bottle to apply the solution evenly to the glass surface and across both sides of the window film material. Covering every area of the film surface generously can help with window graphics installation placement. That’s because it makes sliding and smoothing the film easier.

As you apply the film to the surface of the glass, remove the backing as you go. Using your squeegee can help smooth down any air pockets that might develop as well as remove excess liquid.

## **What’s the Secret of This Window Graphics Installation Solution?**

To ensure you have a good mix with your solution, you may want to run a test installation in an inconspicuous location. This can also help you to see what the right amount is you’ll want to apply. When you do apply it, you’ll quickly see why it works so well. Your DIY solution creates a smooth surface, which makes it easy to slide your window film into place and then adjust it until the positioning is perfect.

## **LINTEC Puts The Power of Window Graphics Installations in Your Hands**

# **FAQs**

 How do I make a DIY window film application solution for LINTEC window graphics?

Combine 1 quart (32 ounces) of purified water with half a capful of baby shampoo. Mix the ingredients thoroughly, then transfer the solution into a clean spray bottle for application. 

 What ingredients do I need to make a homemade window film application solution?

You need 1 quart (32 ounces) of purified water and half a capful of baby shampoo. You will also need a clean spray bottle and a squeegee to apply the solution and smooth the window film. 

 Can I use Dawn dish soap instead of baby shampoo for LINTEC window film installations?

Yes, the original blue formulation of Dawn dish soap can be used as a substitute for baby shampoo. Use half a capful of Dawn in place of the baby shampoo when mixing the solution with 1 quart of water. 

 Is distilled water suitable for making a DIY window film application solution?

Yes, distilled water can be substituted for purified water when preparing a window film application solution. Use 1 quart (32 ounces) of distilled water with half a capful of baby shampoo or the recommended Dawn dish soap substitute. 

 What types of window film can I use a homemade wet application solution on?

LINTEC's DIY window film application solution is intended only for wet-apply window films. Dry-apply adhesive films and dry-apply clings require their own specified installation processes and should not use this solution. 

 How do I apply the DIY solution?

Use a spray bottle to generously and evenly coat both sides of the window film material and the glass surface with the application solution. As you apply the film to the glass, remove the backing gradually and use a squeegee to smooth the material and remove excess liquid. 

 Why should I spray both sides of the window film before installing it?

Coating both sides of the film with the solution creates a smooth surface that makes the material easier to slide and position on the glass. This allows you to adjust the window graphic until it is correctly placed. 

 How much window film application solution should I use during installation?

The solution should be applied generously and evenly across the window film surface to make sliding and smoothing easier. LINTEC recommends testing the installation in an inconspicuous location to determine the appropriate amount for your project. 

 What is the secret behind LINTEC's DIY window film application solution?

The solution creates a smooth surface between the window film and glass and deadens the adhesive, allowing the material to slide into position more easily. This makes it possible to adjust the graphic before smoothing it into place. 

 How do I prevent air pockets when installing LINTEC window graphics?

Use a squeegee as you apply the window film to smooth down any air pockets that develop. The squeegee also helps remove excess application solution during installation. 

 Why should I test my window film application solution before installing a full graphic?

A test installation in an inconspicuous location helps you determine how much application solution to use. It also allows you to practice sliding and adjusting the film during placement.
