Project Description

Hyperdesmo® Aqua was applied as a high-performance coating to refresh and protect an existing painted surface. This application was carried out as a protective refurbishment coating, applied directly over a sound paint layer. The coating, pigmented to RAL 7040, delivered excellent coverage and adhesion with a smooth, durable finish.

Project Requirements

The project required a solution that provided strong hiding power, fast drying and weather resistance, while being easy to apply over the existing paint without the need for removal or priming.

Alchimica® Solution

Hyperdesmo® Aqua was chosen for its water-based, elastomeric formulation that provides a seamless, elastic waterproofing membrane. Its fast-drying time, ease of application and excellent resistance to UV and weathering made it ideal for this refurbishment. The product was pigmented to the specified RAL 7040 colour using standard water-based pigment pastes.

Coating Application

Surface Preparation:

• The existing painted surface was confirmed clean, dry and well-adhered, eliminating the need for primers or sealers.

Product Application:

• Hyperdesmo® Aqua was diluted between 5 and 8% with water to improve workability.
• It was applied by brush and roller directly over the existing paint.

Results

The application achieved excellent hiding power, completely covering the original colour in one coat. The coating’s fast drying and smooth finish enabled a quick turnaround with a durable, weather-resistant protective layer.
