When you buy security window film, you might wonder if the kit includes the application fluid you need. This matters because using the right fluid affects how well the film sticks and looks on your windows.
Most security film kits do not include the application fluid, which is a surprise to many homeowners. You often need to buy a separate slip solution or make your own with baby shampoo and water for proper installation.
Skip the Guesswork on Film Kits
Most security window film kits leave you guessing whether you have enough application fluid or the right sprayer, which turns a simple project into a frustrating mess of bubbles and dry spots. The VViViD Clear Protective 8mil Shatterproof Security Window ends that headache by including everything you need in the box, so you can focus on getting a smooth, glass-like finish instead of hunting for supplies.
I stopped wasting time on incomplete kits the day I switched to the VViViD Clear Protective 8mil Shatterproof Security Window — it comes with the fluid and applicator, so I finally got a flawless install on my first try.

Why Missing Application Fluid Creates Real Headaches
I remember my first security film installation like it was yesterday. I ordered a kit, watched a few videos, and felt ready. Then I opened the box and found no application fluid inside.
That moment of panic is something I want to help you avoid. Without the right slip solution, the film grabs the glass too fast. You end up with bubbles, creases, and a film that looks terrible.
The Emotional Toll of a Botched Installation
My neighbor tried to install security film without the proper fluid. He used plain water, and the film stuck unevenly within seconds. He spent four hours fighting with it, and the result was a wrinkled mess.
He wasted money on film he had to throw away. Worse, his kids were frustrated because the window looked awful. That bad experience almost made him give up on security film entirely.
What Slip Solution Actually Does
Application fluid acts like a lubricant between the film and the glass. It gives you time to slide the film into position and squeeze out air bubbles.
Think of it like this: you would not paint a wall without primer. You should not install security film without the right liquid. The fluid is not an optional extra — it is the difference between success and frustration.
- It prevents the adhesive from bonding too quickly
- It allows repositioning for a perfect fit
- It helps you push out water and air for a smooth finish
How to Get the Right Application Fluid Without Overpaying
After my neighbor’s disaster, I did some digging. I found that most security film brands expect you to buy their fluid separately. That is how they make extra money on top of the film itself.
Honestly, that felt like a trap to me. I did not want to spend another thirty dollars on a tiny spray bottle when I could mix my own solution at home.
My Homemade Slip Solution Recipe
Here is what worked for us: one teaspoon of baby shampoo mixed into a spray bottle of water. That is it. The shampoo breaks the surface tension so the film slides easily.
I have used this trick on three different window projects now. It costs pennies and works just as well as the expensive commercial sprays I have tried.
When You Should Still Buy the Kit Fluid
Some high-end security films come with specific instructions about their adhesive. In those cases, the manufacturer might void your warranty if you use anything other than their branded fluid.
Check your film’s warranty card before you mix your own. If the card says “use only approved solutions,” then follow that rule to protect your investment.
You do not want to install the film perfectly and then lose your warranty over a bottle of soap. That is a risk I am not willing to take with my own windows.
I know the feeling of staring at a box of film with no fluid and wondering if you just wasted your money. That is exactly why I grabbed this kit for my own garage windows after my first failed attempt:

What I Look for When Buying Security Window Film
After installing film on my own home and helping friends with theirs, I have learned what actually matters. You do not need to be a window expert to make a smart choice. You just need to know a few key things.
Check the Film Thickness First
Security film comes in different thicknesses, usually measured in mil. A thicker film like 8 mil stops bricks and break-in attempts, while 4 mil handles storms and minor impacts.
I use 8 mil on my ground-floor windows because that is where someone could actually reach. For upstairs windows, 4 mil is plenty and much easier to cut and handle.
Look at the Scratch-Resistant Coating
Some cheap films scratch if you clean them with a rough cloth. That leaves cloudy marks that ruin the view and make the film look old within months.
I always run my fingernail lightly across a sample piece before buying. If it scratches easily, I move on to another brand.
Measure the Glass Before You Order
Nothing is worse than ordering film and realizing you are two inches short. Measure each window’s width and height, then add an extra inch to every side for trimming.
I keep a simple notebook with all my window measurements. That way, I can reorder without pulling out a tape measure every time.
The Mistake I See People Make With Security Window Film Kits
The biggest mistake I see is assuming the kit has everything you need. People open the box, see the film and a squeegee, and think they are ready to go. Then they spray plain water on the glass and wonder why the film bubbles up.
I have watched three different friends make this exact error. They skipped reading the instructions because they thought installation was simple. Every single one ended up peeling the film off and starting over with the right fluid.
Here is what I wish someone had told me: always read the box label before you start. If it does not mention application fluid, plan to buy or mix some before you even touch the glass. That ten minutes of reading saves you two hours of frustration.
You should not have to guess whether your kit is complete or worry about ruining expensive film on a Saturday afternoon. That is why what finally worked for me was a complete kit with fluid included:
- MINIMIZE PROPERTY DAMAGE by absorbing impact from break-in attempts and holding...
- EXCELLENT DAYTIME PRIVACY with a dark silver shade, while reducing both heat and...
- STRONG ADHESIVE protected by release liner. For easier installation, use A LOT...
My Best Tip: Test Your Fluid Before You Cut the Film
Here is the aha moment that saved me from wasting a whole roll of film. Before I ever cut a single piece, I mix my application fluid and test it on a small scrap of film. This takes two minutes and tells me exactly how the film will behave on the glass.
I spray the solution on a piece of scrap glass or even a mirror. Then I lay the film down and try sliding it around. If it grabs too fast, I know my mixture is too weak and I add a drop more soap.
If it slides too much, I know I need less soap.
This little test has saved me countless times. It is way easier to adjust your fluid before you are standing on a ladder with a wet sheet of film in your hands. I promise you, that is not the moment you want to be experimenting with ratios.
Once you know your mixture feels right, the actual installation becomes smooth and almost relaxing. You can focus on squeezing out bubbles instead of fighting the film.

The most important thing to remember is that application fluid is rarely included, so you need to plan for it before you start your installation. Whether you buy a complete kit or mix your own baby shampoo solution, being prepared makes all the difference.
Go check your film order right now and see if fluid is listed in the box contents — it takes two minutes and might save you from a frustrating Saturday afternoon.
Frequently Asked Questions about Does Security Window Film Need Application Fluid Included in the Kit?
Can I use plain water instead of application fluid for security window film?
Plain water does not provide enough slip for the film to move into position. The adhesive grabs the glass too fast, leaving bubbles and creases that are nearly impossible to fix.
You need a solution that breaks the surface tension of the water. A few drops of baby shampoo mixed into a spray bottle works perfectly and costs almost nothing.
What happens if I install security film without any fluid at all?
Installing dry film is nearly impossible and will ruin your material. The adhesive will stick instantly to the glass, trapping air pockets and creating permanent wrinkles.
You will end up peeling the film off and throwing it away. That is wasted money and hours of frustration that proper fluid would have prevented entirely.
How long does application fluid take to dry after installing security film?
Most application fluids take between 7 and 14 days to fully cure. During that time, you may notice small water pockets that disappear as the fluid evaporates through the film.
Do not try to squeeze these out aggressively. Just let the film sit and dry naturally, and the haze will clear on its own within two weeks.
What is the best security window film for someone who needs clear visibility and shatter protection?
If you want protection without changing how your windows look, you need a clear film that disappears once installed. Your concern about visibility is valid because nobody wants a cloudy or tinted view.
That is exactly why I put this clear film on my own living room windows and have recommended it to friends who want safety without altering their home’s appearance.

Which security window film won’t let me down when I need daytime privacy and light?
Privacy films are tricky because some make rooms feel like caves. You want something that blocks the view from outside while still letting natural light pour in during the day.

Do I need to buy the manufacturer’s branded fluid to keep my warranty valid?
Some premium films require their specific solution to maintain the warranty. Always check the warranty card that comes with your film before mixing your own soap solution.
If the card says approved solutions only, follow that instruction. Losing your warranty over a bottle of soap is not worth the risk, especially on expensive security film.
