Waterproof Paint for Guttering
When compared to other coating products, developing waterproof paint for guttering requires a specific approach and a slightly different set of design principles. All types of gutters need to withstand large volumes of pooling water, especially during stormy conditions. So, what factors need to be considered? We look at how a gutter coating varies from a roof coating.
The design principles behind commercial roof coating products includes easy user application, adhesion, durability, water and UV resistance. However, gutter paint requires some extra factors. Along with being waterproof, this type of product must be highly flexible.
What makes a good paint for guttering?
In today’s working environment, contractors need products to be robust and user friendly. With limited hours allocated to roof or gutter repairs or maintenance, it’s crucial that coatings are designed with fast adhesion in mind. But equally it is essential that gutter paints are waterproof and highly resilient to both UV damage, extreme temperatures and clogging.
Along with pooling water, coatings need to be tough enough to withstand a variety of debris. Mosses, grasses and weeds, nesting birds, and rubbish can all collect in guttering systems causing significant damage over time.
Below are three common issues:
- Pooling water backs up, causing damage to the gutter and surrounding building.
- Where the gutter system has an inadequate fall, over time this could cause the substrate to fail.
- Corrosion (oxidisation) can occur when there’s slow drainage.
Regular gutter maintenance is the key to preventing clogging. Instead of replacing an entire gutter system, a simple solution is to coat with a waterproof gutter paint. So, how are gutter coatings developed and how do they differ from a standard roof coating paint?
Developing a waterproof gutter paint
Although coatings for gutter systems use the same technology as other roof coatings, they have a different resin profile. Gutter paint has a more rubberised coating to cope with prolonged damp and wet conditions. Industrial gutters are designed differently to domestic guttering systems with no fall. Water collects until it reaches a certain height, and it then runs over to the drain. As a result, this type of gutter can be immersed in water for days at a time.
Technologists spend a lot of time in wintry conditions, testing the profile of gutter coatings. They test various substrates including concrete and metal-lined gutters, which are the most common substrates used for guttering systems on industrial buildings. It’s not unusual for testing to include breaking the ice to see how freezing conditions have affected a gutter. As ice creates pressure as it expands, a flexible, robust rubberised gutter paint is essential.
The technicians we use to develop our products are continually testing and improving our Giromax® Guttercoat. We listen carefully to the feedback of the contractors who use our products, which provides us with the foundation for future design parameters. Our aim is to ensure our products can be easily applied during cold, damp conditions.
Our focus is always on how we can improve the application, environmental aspects and affordability. This includes using certain polymers in our gutter coating to provide greater flexibility, UV resistance and adhesion. Read more about How We Test Our Coating Products…
