Caparol Thermosan Self Cleaning Masonry



Matt finish self cleaning masonry.

Innovative silicone-resin binder combination with integrated Nano-Quartz Matrix Structure providing clean facades. Protected against algal and fungal attack. Consequent further development of the Caparol Clean Concept. Product Description.

High-tech facade paint with the essential benefit: Organically cross-linked nano-quartz particles form a compact, mineral-hard, three-dimensional quartz matrix structure against soiling and keep facades clean for a longer period.

Field of Application

The special silicone resin/binder combination effectuates water-repellent, highly water vapour permeable facade paint coatings on mineral and synthetic resin-bound (organic) renders/plasters, coated or uncoated. ThermoSan is suitable for all types of current, sound ETICS/EWI system surface coatings, e.g. synthetic resin (organic) renders and silicone resin renders, lime plasters and limecement plasters.

■ Provided with an encapsulated preservative against deterioration in the coating film due to algal and fungal attack.

■ Alkali-resistant, hence unsaponifiable.

■ Highly CO2 permeable.

■ Non-film-forming, micro-porous.

■ ThermoSan is able to wash fine cracks in render/plaster surfaces.

■ Contains special pigments, showing a photocatalytic effect.

■ Reduces noticeable marks on dark colours, if surfaces are subjected to mechanical loads.

On smooth masonry 5m2 per litre on rougher surface coverage will be less! 

ThermoSan can be tinted with AmphiSilan colourants. If more than one bucket is manually tinted, all product must be thoroughly mixed before use in order to avoid colour differences.

Quantities of 100 litres or more in individual colours may be ordered ready-tinted ex factory. ThermoSan is tintable via the ColorExpress tinting & mixing machine system in limited colour shades of current colour collections. Check tinted product before applying to avoid colour differences. Always use tinted paint of same batch, when applying on seamless surfaces.


Brilliant, intensive colours may have a lower opacity (hiding/covering power). It is therefore advisable to apply a first coat in a similar hiding pastel tint, based on white. A second finishing coat may be necessary. Colour Resistance according to BFS Data Sheet No. 26: (Binder)
