Proper Management of Coated Polyester Racing Awnings: The Problem of Sticking

On this page, we want to talk about a common but easily avoidable problem that can irrevocably compromise the life of this excellent type of racing awning: the phenomenon of coating sticking.

What is the Coating and Why is it Important?

Coated polyester awnings are made with a robust polyester fabric covered with a coating (often on one side). This coating is a special finish that provides two essential functions:

Waterproofing

It creates a barrier that prevents water penetration and protects against rain and humidity.

Durability

It increases the fabric's strength, resistance to abrasion, wear, and atmospheric agents, extending the lifespan of the awnings.

The Problem: Sticking and Detachment of the Coating

When an awning is stored wet or damp in its bag for a prolonged period, the moisture creates ideal conditions for the coating to stick to itself. Once the awning is reopened, the stuck areas separate, causing the coating to detach in patches. This damage is irreversible and permanently compromises both the aesthetics and the waterproofing of the awning.

A Technical Analysis of the Phenomenon

When awnings are stored wet or with high residual humidity, the **PU coating**, due to its polymeric nature, undergoes a process of molecular adhesion with the adjacent fabric surfaces. This happens because water acts as a catalyst, facilitating the adhesion between the polymeric chains of the coating.

When the awning is subsequently reopened, the tensile force applied to separate the stuck flaps is greater than the internal cohesive force of the coating. The result is a partial detachment of the coating, which appears as visible patches.

Important

This type of damage is not covered by the warranty, as it is not a manufacturing defect but a consequence of improper storage.

The Solution is Simple: Never Store the Awning Wet in its Bag.

To avoid this unpleasant and costly inconvenience, you just need to follow a simple rule: before putting the awning back in its bag, you must ensure it is perfectly dry!

What to Do When the Awning is Wet After Use: Practical Tips

On-site Drying

If weather conditions allow, leave the awning set up on its frame for the time necessary to let it air dry completely.

Workshop Drying

If you are forced to take it down in the rain, once you return to your location, open the awning in a covered and well-ventilated area. Let it dry completely before putting it back in the bag.

Final Check

Use a dry cloth to remove any remaining moisture residue in the folds.

Following these simple guidelines will allow you to preserve the integrity and functionality of your racing awnings, ensuring optimal performance and durability for many seasons.
