What is fabric covering in model aircraft building?

In model aircraft building, covering involves wrapping the structure of an airplane (often made of wood) with a heat-shrinkable technical film.

This process allows for:

• to stiffen the structure
• to improve aerodynamics
• to protect against moisture and UV rays

DIACOV 1000 fabric is a professional-grade solution used to achieve a durable, lightweight, and high-performance finish.

Why choose DIACOV for fabric reinforcement?

The DIACOV1000 is specifically designed for demanding model aircraft applications. It is an ideal choice for modelers seeking professional-quality results.

Its advantages:

• Excellent thermal tension (perfectly smooth fabric)
• Very high mechanical strength
• High long-term stability
• Compatible with Diatex finishing systems

What equipment is needed to cover an airplane with fabric?

To successfully apply fabric to a surface using DIACOV 1000 iron-on interfacing, we recommend using the following products:

• Adjustable canvas iron
• Hot-air gun (optional for final tension)
• Diatex-compatible adhesive
• Precision scissors / cutter
• Scraper or cloth

Thorough and careful preparation is essential for the best possible results.

How do you prepare the frame before applying the fabric?

Preparation is a key step in achieving a perfectly smooth surface and ensuring good adhesion of DIACOV 1000.

• Sand the entire structure until smooth
• Remove dust and residue
• Check for any rough spots
• If necessary, apply a primer.

How do you apply DIACOV 1000 step by step?

Here is the recommended method. This technique ensures that the canvas is stretched evenly, without wrinkles or bubbles.

1. Cutting the fabric: Cut the DIACOV 1000 interlining with a sufficient seam allowance.

2. Placement: Place the covering on the surface to be covered.

3. Initial setting: Use an iron set to a moderate temperature (~100–120°C) to set the edges.

4. Thermal stress: Gradually increase the temperature (~130–160°C) to stress the material.

5. Finishing: Carefully finish the corners and complex areas.

What temperature is best for stretching aircraft fabric?

The temperature depends on the steps:

• Curing: moderate temperature (~100–120°C)
• Stress: higher temperature (~130–160°C)

How can you avoid bubbles and wrinkles when applying fabric to a frame?

Defects often result from:

• Improper surface preparation
• Incorrect temperature setting
• Voltage rising too fast

Solutions:

• Work Gradually
• Smooth from the center outward
• Maintain a steady voltage

Can a damaged canvas be repaired?

Yes, DIACOV 1000 fabric makes repairs easy, and the seam is both discreet and sturdy:

• Cutting out the damaged area
• Installing a cover plate
• Thermal reactivation

How long does a DIACOV 1000 canvas installation last?

A well-made canvas mounting can last for several years (typically between 20 and 40 years). DIATEX mounting fabrics are known for their exceptional durability.

Its lifespan depends on:

• storage conditions
• from UV exposure
• the quality of implementation
