Clean the surfaces
Aftermarket
Surface treatment of concrete with Joma products do not only help cleaning the air, but also reduce the need for maintenance by keeping the surfaces cleaner. Our products can be applied onto existing concrete surfaces like building walls and roofs, road dividers, garden walls and pavements. The products are optimised for mineral surfaces like concrete, but can also be used on top of silicate paints.
Maintenance-free concrete is hard to find, but our products will reduce the maintenance intervals on concrete surfaces significantly. For this, we have two product lines, called Joma Clean® and Joma Protect®. Joma Clean® provides self-cleaning by photocatalysis alone, while Joma Protect® combines photocatalysis with water-repellence. These are unique products developed to maximise the self-cleaning effect of the surfaces. The water-repellent surface reduces moisture in the concrete, which impedes the growth of algae and fungi and makes dirt easier to remove.
Do you want to contribute to cleaner air while at the same time spend less time and money on maintenance? Please contact us to discuss which of our environmentally friendly products is the best for your needs.
Joma Clean®
– self-cleaning by photocatalysis
The cleaning-effect of surfaces treated with Joma Clean® is provided by titania alone, meaning that algae, moss and fungi are broken down solely by photocatalysis.
Joma Clean® is the product of choice if you want the visual expression of the concrete to be unchanged, but still like to have efficient photocatalysis and a cleaner surface.
Joma Protect®
– self-cleaning by photocatalysis and water-repellence
In this product, titania is combined with other compounds which give a water-repellent effect to maximise the self-cleaning. Joma Protect® prevents water from penetrating into the concrete, whilst keeping the surface photocatalytically active.
The product leaves the surface diffusion-open, allowing water-vapour to get out. Joma Protect® will shortly after application enhance the colour of the concrete. The product is alkaline (pH 13), which requires use of adequate safety equipment.
Joma Protect White®
– self-cleaning by photocatalysis and water-repellence
Joma Protect White® is another unique Joma product where we have combined the titania with water-repellence to enhance the self-cleaning effect. The product leaves the surface diffusion-open, allowing water to evaporate from the inside.
Treatment of grey concrete with Joma Protect White® leaves a transparent, white impression, making the concrete look brighter. In addition to concrete, it can also be used as topcoat on light-coloured silicate paints.
Application guidelines
Depending on the size of the area to be treated, the products can be applied by spray, brush or roll. One liter covers 8-10 m2, depending on the absorption of the concrete. Cover up any area that should not be affected before starting. Wear adequate safety equipment – please read the safety data sheets before use. Apply until the surface is moist but avoid pooling or running of the liquid. Excessive use can cause discoloration. Surfaces needs to be clean and dry before application and protected against rain for 24 hours after treatment. The surfaces need access to daylight and rain for the photocatalysis to function.
