Several coats may be needed to cover stains or dark colours. The product appears translucent on application, but will become a solid white as it dries. Simply apply to walls or ceilings with a paint brush or roller.

Auro Anti-Mould paint has been designed to protect your home interior from the harmful effect of mould. Its natural formulation is lime based, which prevents mould from growing and spreading. The product is particularly effective in high moisture environments, making it an excellent anti mould bathroom paint for use on walls and ceilings.

If the surfaces to be painted already have mould infestations, we recommend pre-treatment with Auro 412 Mould Eliminator to remove existing growth. This should then be followed by a treatment of Auro 413 Mould Stop Spray to ensure no further growth. The Auro anti mould system is natural, non toxic and effective.

The Anti-mould paint is registered according to the Biocide Regulation at the Federal Institute for Industrial Health and Safety Standards (BAUA).

Ingredients: water, calcium hydroxide, titanium dioxide, mineral fillers, cellulose, alcohol

Coverage: 10 metres squared per 1L

Application: Stir paint well before use. Apply quickly and evenly with a paint brush or roller. Allow 24 hours drying time between coats.

Tips: High PH prevents mould infestation. Any existing mould should be pre treated using Auro 412 and 413 mould cleaning products. The paint appears translucent on application, but achieves full opacity after drying. 

Preventive mould protection thanks to a high pH value! Solvent-free, breathable interior wall paint with a high coverage rate. This mould-resistant product has a lightly textured finish (like small grains) from the milled lime. If covering stains or dark colours, then several coats may be necessary. While applying the product, it appears translucent but becomes a solid white as it dries. Just apply with a roller or brush.

AURO Anti-Mould Paint is specifically designed to protect your home from the harmful effects of mould. With its advanced lime-based formula, it prevents mould from growing and spreading. This paint has a wide range of applications, it can be used as bathroom paint and is especially suited to high humidity environments where emulsion paint just doesn’t offer the protection needed.

In cases of actual mould growth, we recommend the prior use of the spray treatment AURO Mould Eliminator No. 412 to remove existing growth. We offer both products together with the AURO 413 Mould Stop spray as part of AURO’s Anti-mould system. The Anti-mould paint is registered according to the Biocide Regulation at the Federal Institute for Industrial Health and Safety Standards (BAUA).

Application:
Stir well before use, then apply swiftly and evenly with a brush or roller. Allow for 24 hours of drying time between coats.

Tips:
The high ph value prevents mould infestations.
Already existing mould should first be removed with AURO Mould eliminator No. 412.
The paint appears transluscant on application and gets its full opacity only after drying.
Use biocides carefully. Always read the label and product information before using.
