Hydrofuge is a water-repellent impregnation treatment for suitable mineral façades. It reduces the absorption of wind-driven rain without covering the wall with a fully closed paint layer.
It is not a solution for every moisture problem. The façade must be suitable, clean and in good condition, so Nu-Isoleren first assesses the substrate.
Hydrofuge is a colourless water-repellent treatment for suitable mineral façades. The product penetrates the pores of the substrate and reduces rainwater absorption without creating a visible paint film. The wall still needs to be in sound condition before treatment.
A hydrophobic treatment penetrates a suitable mineral substrate and reduces capillary absorption of rainwater.
Hydrofuge is a colourless water-repellent treatment for suitable mineral façades. The product penetrates the pores of the substrate and reduces rainwater absorption without creating a visible paint film. The wall still needs to be in sound condition before treatment.
It is mainly intended for façades that are in sound condition but need extra protection from driving rain. Defects should be repaired first.
Hydrofuge is mainly suitable for porous mineral substrates that can absorb the impregnation. Cracked walls, active leaks, severe salt damage or incompatible coatings should be investigated before treatment.
A correctly applied treatment can reduce rainwater absorption while maintaining vapour permeability.
A hydrophobically treated façade absorbs less rainwater and can dry more quickly after wet weather. This helps reduce weather exposure and moisture-related soiling. It does not replace repairs to defective pointing, cracks or other building defects.
The treatment penetrates a suitable porous substrate and reduces rainwater absorption. It is primarily protection against moisture from outside.
It does not treat rising damp, leaks or internal condensation.
After inspection and any required cleaning, the impregnation is applied evenly until the substrate is sufficiently saturated. Windows, doors and surfaces that must not be treated are protected. Once cured, the appearance of the façade remains largely unchanged.
Moss, algae and dirt can prevent even absorption of the treatment. The wall therefore needs to be sufficiently clean.
Where required, we first carry out façade cleaning.
The façade should be clean and sufficiently dry before application. Moss, algae, dust and deposits can prevent even absorption. Façade cleaning therefore often comes first when the substrate is contaminated.
Hydrofuge can be relevant when a suitable exterior wall absorbs rain. Rising damp comes from the ground and requires a different treatment.
Hydrofuge helps reduce water absorption from driving rain, but it does not treat rising damp from the ground and it does not solve condensation. Correct diagnosis is therefore important whenever damp walls are present.
Correct preparation is essential.

We assess materials, pointing, cracks and moisture.
The façade is prepared where necessary.
The substrate must be sufficiently dry.
The hydrofuge is applied evenly.
Price depends on area, accessibility, substrate condition and whether cleaning or repairs are needed first.
Cost depends on wall area, accessibility, substrate absorption and any cleaning or repair work required beforehand. A free quotation allows the complete treatment to be priced correctly.

Answers about hydrofuge, façade impregnation, moisture, preparation and pricing.
Nu-Isoleren applies a water-repellent treatment to a suitable façade to reduce the amount of rainwater absorbed by the surface, without simply covering the wall with a visible layer of paint.
A water-repellent treatment performs best on a clean and suitable façade. Nu-Isoleren therefore checks the condition of the surface first and, where necessary, cleans it before applying the treatment.
No. The material and condition of the façade matter. Nu-Isoleren therefore assesses the surface first and, where necessary, recommends repairs before applying the treatment.
