When damp appears, the first mistake is often to act too quickly. However, a damp wall gives many clues when you observe the marks, their position and how they change over time. Therefore, a simple method helps you understand the situation better and avoid an unsuitable solution.

With damp solution choice guide, the aim is not to hide marks, but to understand the signs before taking action.

Describe symptoms precisely

The online choice guide becomes more useful when you describe precise symptoms: height of marks, presence of saltpetre, smell, affected rooms and changes over time.

Consider the configuration

Wall type, power socket availability, the affected area and installation constraints all guide the search. For example, an ATE device must be installed only on a damp load-bearing wall, at the bottom of the wall, never on plasterboard, a partition or lining.

Understand the limits

A choice guide does not replace observing the building. It helps structure the search and avoid obvious mistakes. It does not turn water infiltration or a leak into rising damp.

Move forward without excessive promises

The aim is to select a coherent direction and then follow installation and use recommendations. Wall drying remains gradual and takes time.

When a technical solution may be considered

If the signs truly match rising damp, a technical solution may be considered. ATE remains the preferred option when installation is possible and a power socket is available. ATG may suit certain configurations without electricity or when installing a plugged-in ATE is difficult.

Key takeaway

However, caution remains essential: solutions related to rising damp do not treat leaks, water infiltration, flooding or condensation alone.
