There are several important steps and considerations for preparing and applying PVC woven grain decorative film to ensure optimal adhesion and performance:

Surface Cleaning: The surface should be thoroughly cleaned to remove any dust, dirt, grease, or oils. Use a mild detergent and water solution, and make sure the surface is completely dry before application.

Surface Preparation: For surfaces that are rough or uneven, sanding might be necessary to create a smoother base. For very smooth surfaces, a light abrasion can help the adhesive bond better.

Surface Dryness: Ensure that the surface is completely dry before applying the film. Moisture can affect adhesion and cause bubbles or peeling.

Temperature Conditions: Apply the film in a controlled environment where the temperature and humidity levels are within the recommended range specified by the manufacturer. Extreme temperatures or high humidity can affect the film's adhesion and performance.

Cutting and Measuring: Measure and cut the film carefully to fit the surface. It's often easier to work with slightly larger pieces that can be trimmed after application.

Adhesive Activation: Some PVC films require activation of the adhesive by applying heat or pressure. Follow the manufacturer's instructions regarding any necessary heat tools or rollers.

Application Technique: Apply the film slowly and evenly to avoid air bubbles and wrinkles. Use a squeegee or similar tool to press the film down and smooth out any bubbles as you go.

Edge Sealing: For edges and seams, make sure they are securely pressed down. In some cases, edge sealing with additional adhesive or a heat sealer may be necessary to prevent lifting or peeling.

Curing Time: Allow the film to cure as recommended by the manufacturer before subjecting it to heavy use or exposure to moisture. This helps ensure the adhesive has fully set.

Testing: If applying the film to a new type of surface or in a new environment, consider testing a small area first to ensure compatibility and adhesion.

Following these preparation and application steps will help achieve the best results with PVC woven grain decorative film.
