TackStop™ – Premature Tackulation Control Additive for Window Film Installation

TackStop™ is a purpose-built installation additive designed to prevent premature tackulation by slowing the evaporation of water in your slip solution.

On hot glass, in direct sunlight, or during high-temperature installs, slip solutions can flash off too quickly—causing film to grab before it’s properly positioned. TackStop extends working time by keeping the slip wetter for longer, allowing controlled positioning, proper alignment, and smoother squeegee passes.

This is not a slip replacement. TackStop is engineered to be used in addition to your standard slip solution to improve performance under challenging conditions.

What TackStop Does

• Slows water evaporation to delay premature tack

• Extends working time on hot glass and sun-exposed installations

• Maintains consistent slip behavior during positioning and squeegeeing

• Helps prevent pre-tack related issues such as ghosting, creases, and silvering

What TackStop Is Not

• Not a slip solution replacement

• Not an adhesive or bonding agent

• Does not affect final film adhesion

Adhesive Compatibility

• Safe for PSA (Pressure-Sensitive Adhesive) films

• Safe for CDA (Clear Dry Adhesive) films

• Optimized primarily for PSA-based window films

TackStop does not interfere with normal water evacuation or curing. Once squeegeed out, moisture behaves as expected and the film cures normally.

Ideal Use Cases

• Direct sunlight installations

• Hot exterior or interior glass

• Large panes and vertical glass

• Great for mobile automotive tinters working outdoors or in uncontrolled environments

• Automotive, residential, and commercial flat glass installs

Designed for Professional Installers

TackStop was developed to solve a common real-world problem: losing control of the film because the glass dries too fast. By extending moisture retention without altering long-term adhesion, TackStop provides more working time—without compromising finish quality, clarity, or cure.

No ghosting.
No creases from pre-tacking.
No silvering.
Water evacuates normally and the film cures as expected.

How to Use

Add TackStop to your existing slip solution at the recommended dilution. (1 oz. per gallon is the suggested starting point)

Adjust concentration based on temperature, sun exposure, and installation conditions.

Always test before full installation.
