※ Since patterned films require alignment, please order 20~30% more than the calculated amount.

Please check.

  • The width of the film is usually fixed at 122 cm. Please position it based on the shorter of the horizontal and vertical sides of the surface to be attached.
  • If there are curves or the finishing surface needs to be wrapped, there must be an allowance of at least 5cm on all sides compared to the actual dimensions to ensure stable cutting.
  • You must completely remove oil or dust from existing furniture using a degreaser (such as alcohol] to prevent the corners from lifting over time.
  • The strongest adhesion is achieved when the material is attached in a 'touch-dry' state (when it feels sticky to the touch] after applying the primer.
  • If air bubbles form, make tiny holes with the tip of a knife to release the air, and use a spatula to push from the center outwards.

Interior Film/Adhesive Sheet Quantity Calculator, Furniture, Door, and Kitchen Sink Refurbishment Quote Guide

How many meters of adhesive film will you need to cover both the upper and lower kitchen cabinets? Since interior film is difficult to modify once applied and color variations between lots may occur if you place additional orders due to a shortage of materials, it is important to calculate accurately from the start. This calculator precisely determines the actual required film length (in meters] by taking into account the size of the item to be refurbished, the film width, and the finishing allowance.

Interior Film Quantity Calculation Formula

The film requirement is calculated based on the length of the attachment surface and the required number of strips.

Total required length
Required length (m] = {(Length of attachment surface + Finishing allowance] × Required width} × (1 + Markup rate / 100]
Required width
Width = Rounded up (Mounting surface width ÷ Film fixing width]

Interior films are usually produced with a fixed width of 1220mm, so you must first determine the required width based on the width of the surface to be attached.

Detailed Guide to Calculator Input Items

Please verify the actual dimensions of the mounting surface and the working method for an accurate quote.

1. Width and height of the attachment surface

Enter the total width and height of the surface to be coated (room door, kitchen cabinet door, etc.] in millimeters. If there are multiple doors, please sum the total areas and enter the result.

2. Film width and finishing allowance

The standard film width is 1220mm. The finishing allowance is the length that wraps around the corners and folds to the back, usually leaving a margin of about 50mm to 100mm on all sides (top, bottom, left, and right].

3. Surcharge rate

This is an allowance to cover cutting errors or pattern matching. It is safer to allow a generous 10–15% for solid-color films, and 20–30% for grained films such as wood or metal.

Expert Know-how and Checklists

This is the core know-how that determines the quality of film installation.

  • Application of water-based primer

    Be sure to apply a water-based primer to corners, curved areas, and MDF surfaces, and let it dry before attaching. This will completely prevent the film from peeling.

  • Bubble removal and finishing methods

    Push the roller from the center outwards to remove the air. Any remaining air bubbles can be removed by gently poking them with the tip of a needle and then rubbing.

  • Using a hair dryer (curved surface installation]

    The film does not adhere well to angled or curved surfaces because it is stiff. Applying heat with a hairdryer makes the film flexible, allowing it to wrap neatly even on curved surfaces.

Frequently Asked Questions (FAQ]

  • Q. Are adhesive sheets and interior films different?
  • A. They are different. Sheet paper is made of thin vinyl material and is suitable for stationery, whereas interior film is made of thick, durable PVC material and is a specialized material used for refurbishing furniture or doors.
  • Q. Can I apply it over the existing adhesive film?
  • A. It is possible if the existing surface is firmly attached. However, if there are torn or lifted parts, you must remove them or level them with putty before attaching to achieve a clean finish.
  • Q. Do I need to remove the sink cabinet doors and reattach them?
  • A. Yes, it is much easier and produces better quality to unhing the hinges, remove the door, and work on it while it is laid on the floor. I also recommend removing the handle beforehand.
