About ERSTOMOULD

Mould-neutralizing interior coating

ERSTOMOULD is a functional, styrene-acrylate-based interior coating for the treatment and prevention of mould growth. The product is applied directly to mould-infested mineral substrates, encapsulating and neutralizing both visible mold and deeper mycelial structures.

This technology eliminates the need for conventional chemical or mechanical pretreatment in many cases. ERSTOMOULD is vapour-permeable, solvent-free, odourless, and, according to the test report, suitable for use in food contact environments.

Operating Principle

Application of erstomould on a mold-infested wall

How does ERSTOMOULD work?

  1. 1. Mechanical-capillary integration:

    The formulation penetrates the near-surface capillary layer and binds existing mycelial components.

  2. 2. Neutralisation of mould infestation

    Special active components neutralises the visible surface mould and the deeper mycelial zones in the capillary system.

  3. 3. Surface protection & prevention

    The coating forms a diffusion-open, carbonation-inhibiting protective film that significantly reduces renewed infestation, provided the cause is addressed through appropriate remediation.

FAQ

Frequently asked questions about ERSTOMOULD

Can ERSTOMOULD be applied directly to mould?

Yes, ERSTOMOULD is designed for the functional treatment of mould-infested surfaces according to the system description. However, loose or unsound layers must be removed.

Is ERSTOMOULD suitable for sensitive interior spaces?

Yes, ERSTOMOULD is solvent-free, odourless, free of silver ions and nanoparticles, and suitable for sensitive interiors after proper processing.

Can ERSTOMOULD be used in food-related areas?

After proper processing and complete drying, the system is suitable for food contact areas according to the test report. Specific application depends on the location, substrate, use, and approved documentation.
