A well-maintained school building contributes to a positive learning environment and the image of an educational institution. This was no different for the Dalton College in The Hague. After years of intensive use and exposure to weather conditions, the facade frames had lost their original appearance. The colour had become dull, the surface was dirty, and the protective properties of the existing coating were visibly diminishing.
In order to give the building a fresh, representative appearance again and to protect the frames in the long term, a smart restoration solution was chosen: a combination of deep cleaning with Cleaner and a finish with 2C Perma Coat Gloss, a transparent, protective coating with a colour-restoring effect.
Purpose of the treatment
The work carried out had several objectives:
- Restoring the colour of weathered, dull frames
- Restoring the protective effect of the existing powder coating
- Providing long-term protection against UV, moisture and pollution
- Realising a glossy, fresh finish without repainting
- Extending the lifespan of the existing materials
- Carrying out cost-saving maintenance without disrupting school activities
Technical approach and products used
Step 1: Cleaning with Cleaner
The first step consisted of an intensive cleaning with the product Cleaner. This step is crucial for removing:
- Atmospheric dirt, soot and dust
- Limescale, grease and oil residues
- Old maintenance products or wax layers
- Contamination that can hinder the adhesion of the coating
This preparation ensures a clean, slightly porous surface to which the new coating can adhere optimally.
Step 2: Applying 2C Perma Coat Gloss
After the surface has dried, 2C Perma Coat Gloss is applied in one layer. This two-component coating:
- Restores the original shine and colour perception
- Forms a dirt and water-repellent layer of approx. 15–20 microns
- Protects against pollution, rain, UV light and temperature fluctuations
- Resistant to light mechanical stress (such as touching or abrasion)
- Easy to clean with a damp cloth or neutral cleaning agent
Why this approach for a school building?
Educational buildings such as Dalton College have specific maintenance needs:
- They are used intensively by hundreds of pupils and staff
- Maintenance must be carried out quickly and without inconvenience
- Budgets are limited, so cost-efficiency is crucial
- The appearance of the building influences the experience and reputation of the school
This treatment fits in perfectly with this: the frames look as good as new again, without the need for time-consuming or expensive renovation.
Sustainability and environmental benefits
The chosen approach also offers a clear environmental benefit:
- No replacement of materials = less waste and raw material use
- Limited use of paint or solvents
- Sustainable extension of the lifespan of existing window frames
- Lower maintenance frequency = fewer resources and labour in the future
In this way, the project contributes to sustainable real estate management within education.
