Product Overview
Polymeric Wall Vinyl is a specialized cast vinyl film manufactured with advanced polymer chemistry for interior architectural applications. Its formulation prioritizes dimensional stability, conformability to textured surfaces, and clean removal after extended periods.
This material features a low-tack, repositionable adhesive system designed specifically for painted drywall, plaster, and other interior wall substrates. It resists bubbling and wrinkling during application and maintains its appearance over time without damaging underlying paint upon removal. The matte finish minimizes glare and provides a surface that is receptive to various printing technologies.

Product Benefits
Polymeric Wall Vinyl provides specific benefits for interior wall graphics, addressing common challenges in large-format installations.
Dimensional Stability
Minimal shrinkage and expansion due to its cast construction, preventing edge lifting and ensuring seamless panel alignment in murals.
Wall-Safe Adhesion
Controlled adhesive strength bonds securely to painted walls without causing damage to the paint or drywall upon removal within the specified period.
Bubble-Free Application
Micro-perforated adhesive layer and air-egress channels allow trapped air to escape during installation, reducing labor time and material waste.
Product Features
The design of Polymeric Wall Vinyl incorporates features tailored for professional interior graphic installations.
- Textured Matte Finish: Mimics the look of painted walls, reducing visible seams and hiding minor surface imperfections.
- Repositionable Adhesive: Allows for adjustment during installation without losing tack or stretching the film.
- Wide Format Compatibility: Manufactured in rolls up to 74" wide for seamless large-scale mural production.
- Ink Receptive Layer: Treated surface for optimal adhesion of eco-solvent, solvent, and UV-curable inks.
- Conformable Construction: Flexible enough to conform over lightly textured surfaces like orange-peel or knock-down wall textures.
- Stain Resistance: Surface can be cleaned with mild detergent and water without damaging the printed image.
- Low Glue Migration: Adhesive formulation minimizes the risk of adhesive residue or staining upon removal.
- Printable Backing: Liner is printable for registration marks and job information.

Application Substrate Guide
| Substrate Type | Surface Preparation | Expected Bond | Removability Window | Key Consideration |
|---|---|---|---|---|
| Latex-Painted Drywall | Clean with isopropyl alcohol; ensure paint is cured (30+ days). | Excellent | Up to 5 years | Most common and recommended substrate. |
| Gloss/Enamel Painted Walls | Light sanding may be required to improve adhesion. | Good | Up to 3 years | Test adhesion on a small area first. |
| Primed & Painted Plaster | Ensure surface is smooth, sealed, and free of dust. | Excellent | Up to 5 years | Ideal for historic building renovations. |
| Glass & Glazed Ceramic Tile | Thorough cleaning with glass cleaner. | Very Good | Up to 7 years | Removal is typically clean and residue-free. |
| MDF/Laminate | Ensure surface is sealed and non-porous. | Good | Up to 4 years | Not recommended for unfinished wood. |
Installation & Handling Tips
Environment Conditioning
Acclimate the vinyl and the substrate room to the same temperature (ideally 68-77°F / 20-25°C) for 24 hours prior to installation.
Panel Alignment & Seaming
For multi-panel murals, overlap panels by 1/16" (1.5mm) and cut through both layers with a sharp blade for a butt-seam appearance.
Application Fluid
A light mist of soapy water (2-3 drops of dish soap per quart) can aid in positioning but must be fully squeegeed out.
Curing & Post-Installation
Allow 72 hours for the adhesive to achieve full bond strength before subjecting the graphic to cleaning or high humidity.
Frequently Asked Questions
Common inquiries regarding the use, performance, and specifications of Polymeric Wall Vinyl.
Will Polymeric Wall Vinyl damage my painted walls upon removal?
When applied to a properly prepared, fully cured (minimum 30 days) latex or acrylic painted surface and removed within the specified 5-year window, it is designed for clean removal without damaging the paint. Removal technique (pulling back at a 180-degree angle slowly) is also important.
Can this material be used on exterior walls or windows?
No. Polymeric Wall Vinyl is formulated for interior use only. Its adhesive and face film are not designed to withstand UV radiation, constant moisture, or extreme temperature fluctuations, which would lead to premature failure outdoors.
What printing technologies are compatible with this vinyl?
It is compatible with eco-solvent, solvent, UV-curable, and latex inkjet printers. A primer is not typically required. Always conduct a small test to ensure ink adhesion and desired color output.
How do I handle seams in a large mural installation?
The material's dimensional stability minimizes panel movement. Use the "overlap and double-cut" method: overlap panels by a minimal amount, use a straightedge and sharp blade to cut through both layers, then remove the waste. This creates a nearly invisible butt seam.
What is the recommended method for cleaning wall graphics made with this material?
After the 72-hour cure period, clean with a soft cloth or sponge dampened with a solution of mild, non-abrasive detergent and water. Avoid abrasive cleaners, scouring pads, high-pressure washers, or solvents like acetone or thinner.
