Features & Benefits
- When applied on a porous substrate, Antipluviol W penetrates deep down and reacts with the natural humidity present in the said substrate to form a hydrophobic, water-repellent layer inside the pores and capillaries
- Forms an efficient barrier against aggressive agents present in the atmosphere, which are carried into the material by rainwater. The water-repellent treatment formed by Antipluviol W also improves the self-cleaning effect of the façade and reduces the capacity of moss and mildew from adhering to the material
- Does not form a film on the surface. Therefore, the material’s permeability to water vapour is not modified and the appearance of the surface remains practically unaltered
- Has excellent resistance to alkalinity and UV rays and maintains its water-repellent properties over a long period of time
Recommendations & Limitations
- Antipluviol W is not suitable for impregnating the following:
- Horizontal surfaces (terraces)
- Basements
- Water tanks
- Walls subject to rising damp carrying salts
- Lift wells and areas subject to water under pressure
- Gypsum surfaces
- Synthetic plasters and surfaces decorated with synthetic paint
- Carry out a preliminary test to ensure no colour changes take place on the substrate when Antipluviol W is to be used on natural stones, coloured renders or on other types of substrates which show no uniform absorbency
- Do not apply Antipluviol W on damp substrates or on substrates that are not well cured
- Do not apply Antipluviol W if the temperature is lower than 5°C or higher than 35°C (the surface must be dry in all cases and must never be exposed to direct sunlight)
- Do not apply Antipluviol W if the level of humidity is higher than 85%
- Do not apply Antipluviol W if it is about to rain or in windy weather
