Installation Guide

Installation

Fit It Yourself. No Specialist Gear.

Techni Tint film is applied wet, from the inside of the glass. If you can keep a panel clean and work patiently with a squeegee, you can fit it. Read every step before you start — the prep does more for the finish than the application does.

What You'll Need

  • Slip solutionWater + 2–3 drops of baby shampoo
  • Spray bottleFine mist, 500ml+
  • Hard card squeegeePlus a soft-edge squeegee
  • Heat gun or hairdryerFor shrinking curved glass
  • Sharp bladeSnap-off, fresh section per cut
  • Lint-free towelsTwo — one damp, one dry

The Process

  1. 01

    Clean the Glass Properly

    Spray the inside of the glass with slip solution and scrape the whole surface with the blade held flat. Work the rubber seals and the bottom edge hardest — that's where grit hides and where you'll see it later. Wipe out, re-spray, squeegee dry, then check the glass at an angle against the light. Any speck you leave here becomes a permanent bubble.

    Don't rush this step

    Cut the Film to Shape

    Wet the outside of the glass and lay the film on it with the liner side facing outward, so the film sits in place while you work. Rough cut around the glass, leaving roughly 10 to 15mm of extra film on every edge, then trim back to the shape you want. Cutting on the outside means a slip of the blade never touches your interior trim.

    Keep the liner on until step 4
  3. 03

    Shrink Any Curve Out of It

    Curved glass needs the film heat-shrunk to fit flat. With the film still on the outside of the glass, pass the heat gun over the raised fingers of film from a distance and tap them down with a soft squeegee as they relax. Move constantly and never park the heat in one spot. Repeat until the film lies flat with no lifted edges.

  4. 04

    Peel the Liner and Wet the Adhesive

    Peel the clear liner off, spraying the adhesive side generously as you go so it never touches itself. Keep it soaking wet — a dry patch of adhesive will grab the glass instantly and you'll be left with a crease. Re-spray the inside of the glass at the same time.

    Wetter is better
  5. 05

    Position and Squeegee Out

    Lift the film into the vehicle, adhesive side to the glass, and float it into position — it should still slide while wet. Once it's sitting right, squeegee from the centre outwards in overlapping passes, pushing water and air to the nearest edge. Spray the top side of the film first so the squeegee glides instead of scratching.

    Work top to bottom, then corner to corner, until no water moves under pressure.

  6. 06

    Trim the Edges and Finish

    Trim the film back to a hairline gap of about 1mm from the glass edge, so there's nowhere for the seal to catch and lift it. Wrap the hard card in a lint-free towel and do a final firm pass over the whole panel, especially the perimeter and around any defroster lines. Dry the seals and door card before you close up.

Get a Better Finish

  • Work in shade, out of wind, on a warm dry day. Direct sun dries the film before you can position it; wind puts dust on your adhesive.
  • Do the easiest window first to get your technique in before you touch the panel that matters most.
  • Change your blade section often. A dull blade tears the film instead of cutting it.
  • Fingerprints on the adhesive show up permanently — handle the film by its edges only.
  • If you crease the film, stop. A crease won't squeegee out. Re-cut that piece.

Curing and Aftercare

  • First 3–5 DaysLeave the windows up. The adhesive hasn't set and rolling down can peel the edge.
  • Haze and Small PocketsNormal. That's trapped moisture leaving the film — don't pick at it or try to squeegee it out.
  • Fully ClearUsually 1–2 weeks depending on heat and humidity. Cold, damp weather takes longer.
  • Cleaning After ThatAmmonia-free glass cleaner and a microfibre cloth. Ammonia breaks the film down.

Compliance: 

Tint laws vary between Australian states and territories, including requirements for Visible Light Transmission (VLT), reflectivity, and where certain films may be legally installed.

It is the customer's responsibility to ensure the selected film complies with the road rules applicable in their state or territory before installation. Some films and finishes may be intended for show vehicles, off-road use, motorsport, or display purposes only and may not be legal for use on public roads.

Techni Tint does not guarantee that every film is road legal for every application or jurisdiction. Before fitting any window film to a road-registered vehicle, we recommend checking the current requirements with your relevant state or territory road authority.

We encourage all customers to install and use our products responsibly and in accordance with Australian laws.
