PDLC Film Installation
Everything you need to know to install PDLC film on existing glass — tools, steps, wiring, and professional tips.
PDLC Film Installation Overview
PDLC film is available in two installation formats: self-adhesive retrofit film (applied to existing glass) and laminated PDLC interlayer (factory-bonded between two glass panes). This guide covers self-adhesive installation — the most common retrofit application.
The self-adhesive PDLC film is applied wet using a slip solution, then squeegeed flat. Electrical bus bar leads along the edges of the film connect to a compact PDLC transformer that you connect to your electrical system.
Most single-panel installations take 1–2 hours including cleaning, application, and wiring. No special tools are required beyond what is included in the installation kit.

Step-by-Step PDLC Film Installation
Follow these steps for a bubble-free, professional-grade PDLC installation.
Prepare & Clean the Glass
Thoroughly clean the glass with a lint-free cloth and quality glass cleaner. Remove all dust, oils, fingerprints, stickers, and silicone residue. Any contamination trapped under the PDLC film will create permanent bubbles. For best results, clean twice and allow to dry completely.
Prepare the PDLC Film
Unroll the PDLC film and allow it to lay flat for 15–30 minutes to release any roll memory. Confirm the panel dimensions match your glass. Identify the bus bar leads (silver strips along the edges) — these are your electrical connections. Do not cut or trim the bus bars.
Mix Slip Solution & Wet the Glass
Add 1–2 drops of dish soap to 16oz of clean water in your spray bottle. Mist the glass generously. This solution prevents the adhesive from bonding immediately, giving you time to position the film correctly. You have approximately 5–10 minutes to reposition before the adhesive sets.
Apply the PDLC Film
Peel 6–8 inches of the release liner from one edge of the film. Place that exposed edge on the wet glass, aligning it with the corner. Slowly peel the remaining liner while laying the film down onto the glass. Work from top to bottom, keeping the film taut. Avoid letting the film fold onto itself.
Squeegee Out Bubbles & Water
Starting from the center of the panel, use the squeegee card to push water and air bubbles toward the nearest edge using firm, overlapping strokes. Work systematically outward. Some micro-bubbles may remain initially — these typically dissipate within 24–48 hours as residual moisture evaporates.
Trim Edges (if required)
If the film extends beyond the glass edge, use a utility knife with a fresh blade to trim flush with the glass. A metal straight-edge ruler will help achieve clean, straight cuts. Seal all edges immediately after trimming with the provided edge sealant to prevent moisture ingress.
Connect the Electrical Leads
Connect the film's bus bar leads to the PDLC transformer using the provided quick-connect terminals. The film operates on 48–65V AC output from the transformer. Route the low-voltage wire to the transformer location. The transformer plugs into standard 120V or 220V AC. A qualified electrician should connect the AC supply circuit.
Test & Verify Operation
Power on the transformer and actuate the switch. The glass should transition from opaque (off) to clear (on) in approximately 50 milliseconds. Test multiple switch cycles. Inspect for any delamination at edges or persistent large bubbles. Contact our support team immediately if you observe any issues.

Laminated PDLC Glass
For new construction or high-specification projects, PDLC film can be factory-laminated between two glass panes.
PDLC Laminated Glass Construction
The PDLC interlayer is bonded between two glass panes under heat and pressure in a controlled factory environment — similar to safety/laminated glass construction. The result is a self-contained PDLC glass unit ready to install in standard glazing frames.
Benefits of Laminated PDLC
- No visible edge sealing required
- Glass looks identical to standard laminated safety glass
- Suitable for structural glazing applications
- Higher clarity in transparent state
- Compatible with curved glass
- Meets safety glazing standards (ANSI Z97.1, EN 12600)
