1) Spray NOMO Professional directly over the area affected by mold. Since the mold may already have spread invisibly, also spray the surrounding area (approx. 20-30cm).


2) Leave NOMO Professional to act for about 15-20 minutes so that the mold becomes inactive.


3) Then clean the infested area with water and a sponge, brush and/or pressure washer. In some cases, the mold will leave stains or residue. If a bleach or other product is used for removal, rinse very thoroughly to ensure no residue remains.

Allow the surface to dry completely before proceeding to step 4.


4) Reapply NOMO Professional to create an anti-mold barrier. Spray NOMO Professional on as a fine mist. Avoid dripping! Allow the product to completely.

When applied as prescribed and after complete drying, NOMO Professional is resistant to water and UV radiation.


The treatment of surfaces with NOMO Professional does not result in any changes or discoloration of paints or coatings.


Surfaces treated with NOMO Professional lose their protective barrier as soon as they are cleaned with chemicals such as chlorine, ammonia, hydrogen peroxide, among others. Furthermore, the protective barrier of NOMO Professional is removed by hard scrubbing or the use of high-pressure cleaners. In this case, it is necessary to reapply NOMO Professional.

Due to its water resistance, NOMO Professional can also be applied to surfaces exposed to liquids (e.g. in the shower).


Should these surfaces be cleaned with acid or bleach, NOMO Professional must be reapplied.
