Step by step instructions on how to apply window film & frost glass

Regardless of the type of window film or stickers you purchase, the principle will be the same. We also have several targeted video tutorials which you will find by clicking here

Glass Preparation (the crucial task)

Glass preparation before applying window film.

Make a slip solution using a few drops of washing up liquid mixed with water in a spray bottle and toughroughly clean the glass. Use a glass scraper to remove specks of paint.

Film Cutting

Unless your film is already cut to size, and if the film has a paper liner with a metric grid, measure your glass at the top and bottom, and left and right and mark and cut your film. You can also cut the film bigger than required and trim the film once applied to the glass.

Film Application

A. Throughroughly wet the glass with the slip solution.

B. Place the film face down an a flat surface and expose a small amount of the adhesive or cling side.

C.  Spray the adhesive or cling side liberally with the slip solution as you peel off the protective liner.

D. Slip the adhesive or cling side of the film on the glass butting one edge and the top against the window frame or rubber gasket (double glazed unit).


Squeegee Technique

A. Liberally wet the face of the film with the solution to act as a lubricant fro your squeegee or felt edged tool.

B-C. Squeeze out the solution from under the film using a firm and even pressure, starting from the top and working your way down and accross the film.

Film Trimming

Run a credit card and a retractable knife blade down the edge of the glass to trim any excess film. The thickness of the card will allow for a small gap to help any remaining solution to be squeezed out. Once trimming is complete go over the film once more to squeeze out all the solution. 

Final Checks

1. Make sure that all the solution has been squeezed out.

2. Wipe the film and any remaining solution with paper towel.

3. Inspect the film on both sides of the glass to check for any trapped solution or air bubbles.

How To Remove Window Film

Removing window film can be a very easy process, but it all depends on how long the film has been on the glass, and the type of film that was used.

Here's a video tutorial which shows the basic principal.

Typically, films are either made using PVC or PET.

PVC is  a soft material which can be peeled off the glass with a glass scraper. Any glue residue can be removed with soapy water and a scraper.

PET is a brittle material widely used for solar and safety film, and might be made of layers of mettalised material. To remove this type of film, use a wide glass scraper and lubricate with soapy water to remove the film.

As a rule, old PET film are more difficult to remove than PVC films.

For large panes, it is best to first score the film into strips with a sharp knife. This means that you can tackle it in more manageable pieces.


How To Care For Your window film After Installation

Window film is very easy to look after and you won't need any special products to clean it with. In fact, soapy water, similar to the solution you used to apply the film is the best cleaning product. 


Wait for at least 3 weeks before first cleaning your film

Use soapy water

Use a soft cloth or paper towel

Use a rubber edged squeegee (unless the film is printed or has cut outs) in good condition


Do not use abrasive products

Do not use Amonia based products

Do not use defective or damaged squeegees

Caring for printed films, or films with cut-outs

Extra care must be taken when cleaning printed films, or films which have been cut out and have exposed edges. Gently clean with a soft cloth only, and take particular care around the cut areas. Do not rub too hard or use a squeegee as it could damage the print or your cut film.

Caring for static cling films & stickers

Take extra care around the edges and clean your sticker or film from the centre out. Do not use a squeegee.

Product Description

Writing or drawing on the Film
Always check suitability of white board marker pens on an offcut of film.

Surface Preparation: Walls, plastered surfaces
For the film to adhere properly, the painted wall should be smooth, flat, dust free and free of imperfections. The film will not adhere to a bare plaster finish unless painted or varnished first. 

Surface Preparation: Painted surfaces

  • On older paint work, we would recommend a light sanding down to help with adhesion, and to remove any imperfections. 
  • On recent paint work, a clean with soapy water would suffice.
  • On new paint work, please wait 2 weeks for the paint to totally cure before applying the stickers.

Surface Preparation: Laminates, metal surface, wood.
Laminates, like kitchen door coverings for example will require a thorough clean with soapy water to remove any greasy cooking deposits.
Bare, untreated metal surfaces should be thoroughly cleaned to remove any oily deposit.
Wooden surfaces should be lightly varnished for best results.

Applying the Stickers
Cut the material to the required size, unless you have ordered the material made to measure.
For small pieces, just remove the protective liner to expose the adhesive side, line up and apply the sticker to the surface. Once you are satisfied with the position, smooth the sticker firmly onto the surface using the felt edge tool supplied with your order. 
For larger pieces, peel back and fold down 4" (10cm) off the top of the backing paper to expose the adhesive side. Apply and line up the top of the film to the surface . Once you are satisfied with the position, peel off the rest of the backing paper from behind the film in stages, and smooth down as you go along using the felt edge tool supplied with your order. Once the whole of the film has been applied, go back over the whole thing using more pressure. 

If any trimming is required, just use a retractable knife and trim the excess material. Just be careful as the material is quite thick. Use a straight edge like a metal ruler if necessary.
