If you’re looking for a quick and simple guide to install plastic film on your windows? then you’ve come to the right place. This concise guide will tell you everything about the exact process on how to install the film, how to get the perfect finish, and some general tips that will help you to get your project underway.

Step One - Get the Right Tools

Before you embark on any attempt to install plastic film on your windows, the first thing that you need to do is make sure that you have the right tools. Sounds very basic but it’s something that will help you make progress from the beginning. The tools aren’t specialized and you won’t need anything that you can’t find in a simple DIY toolbox here, so you shouldn’t need to go out and buy any specialist equipment. Some of the things you’ll need are listed below:

  • Knife with a snap-off blade

  • Glass scraper

  • Rubber squeegee

  • Lint-free cloth

You’ll also need a spray bottle, which has been filled with a slip solution. You can make a slip solution by mixing baby shampoo (Johnson’s is great) with a pint of cold water. Aim to mix around one teaspoon of shampoo for every pint you think you’ll need. Of course, you can adjust this ratio if you’re doing multiple windows, or if you are working on a large project.

Step Two - Measuring

Measuring is incredibly important, as it will determine how smoothly the rest of the process goes. By measuring the window precisely and noting the width and length, you can then cut the window film to size and ensure the perfect fit. Top tip - cut the film so it’s slightly oversized, so you have a bit of leeway in the future.

Step Three - Preparation

Preparation is key if you a smooth process from start to finish, therefore you want to prepare your glass in advance to ensure your window doesn’t attract any grit, dirt or water bubbles when it is put up. In order to do this:

  • Spray the solution onto the whole glass panel, aiming for a fine mist.

  • Then, clean the glass using your scraper. Be mindful that you don’t neglect the edges.

  • Once done, spray the window again, using your squeegee to remove any water from the glass.

Step Four - The Liner

Next, you will have to remove the backing liner. The backing liner on a lot of window films is clear. If you’re using vinyl then you may find that it’s got a paper backing instead. When you remove the liner, spray down the sticky side with the solution. It’s a good idea to do this as you peel.

Step Five - Installation

Now you have taken care of the preparation, you need to apply the window film onto your glass. At this point, you should have a wet window, and the sticky side of the film should be wet too. Place the film on the glass, adhesive side down, and then use the squeegee to dry the water that’s behind the film.

Step Six- Trimming

This part will require a steady hand. Cut around the edges of the film and follow the edge of your panel. You have a choice to use the trim guide, but you can use the squeegee if you prefer.

Step Seven - Drying

It’s super important that you do not leave any water behind. Once it’s all dried, you may have some bubbles in the film. Use the squeegee three times, to make sure you don’t have any unsightly bubbles ruining your window film. This is a super easy step, but it’s one you won’t want to overlook.

So there you have it. It’s very easy for you to apply window film, and with a bit of care and attention, you’ll soon find that it is easier than ever for you to get the result you are looking for.
