Tinting your own windows: a first-timer’s DIY guide

The tools, the order of work, and the mistakes that cause bubbles and lifted edges.

What you need

  • Film cut with some spare: a 52cm × 3m sheet covers most side windows
  • Spray bottle with water and a few drops of baby shampoo
  • Hard card, soft squeegee and a sharp snap-off knife
  • Lint-free cloths and a heat gun for curved rear screens

Our Starter tool kit has the basics; the Pro kit adds what we use in the studio.

The order of work

  1. Clean the glass twice, including the edges and seals. Dust is the main cause of specks.
  2. Cut the film roughly to shape on the outside of the glass, liner facing out.
  3. Shrink curved screens on the outside with gentle heat until the film lies flat.
  4. Spray the inside glass and the adhesive side generously as you remove the liner.
  5. Apply the film, slide into position, then squeegee from the centre outwards.
  6. Trim the final edge and push out remaining water with the hard card.
Most common mistakes
  • Not enough slip solution, so the film grabs before it is positioned
  • Working in a dusty or windy space
  • Rolling the window down before the film has cured

When to call us instead

Rear screens with heavy curves and dot-matrix edges are hard to get right first time. If you would rather not risk it, book a fitted tint from £100.
