Use and Care Manual

PhotoActiva TB does not form a film. Once dry, it does not alter the properties or appearance of the
substrate.
PhotoActiva TB is mainly applied on porous mineral surfaces (marbles, natural stone, ceramics, mortars,
bricks, etc.). In case of applying on organic materials, as wood or plastics, or on painted surfaces, it is
recommended to check the substrate resistance to photocatalysis, since its ability to destroy pollutants
may result in the destruction of the pigments and the binders of the base paint, or the organic
substrate. This effect may not be immediate, and be seen within a few months
The active particles are incorporated and remain in the surfaces thanks to its capacity of penetration
and to its binding compatible with the surfaces to treat
PhotoActiva TB has built-in mineral binders. Its incorporation into the surfaces is obtained by a
combination of penetration in the pores, and adherence to the surfaces. This grip is gradual, and it can
take up to 10 days to reach its maximum.
During the first days after application, if the surfaces are subjected to water or rain, water can drag a
small part of the material. This elimination will be lower the more porous the surface is, and when more
days have passed since the application. As a general rule, it is recommended not to apply the product
outdoors if rain is foreseen in the next 24-48 hours
Elimination of the photocatalytic effect may be obtained by coating the surface with a film producing
coating, as a standard non photocatalytic paint
