Why choose Beissier Humidity Stain Remover
- ✓ Ready to use — direct application without dilution — shake and spray directly onto the stain; no mixing, no preparation; the 750ml spray format allows precise treatment of specific areas
- ✓ Highly effective against mold, mildew, algae, and grime — acts on the microorganisms responsible for stains, eliminating them thoroughly and not just masking the surface stain
- ✓ Preventive action — prevents re-occurrence — periodic use on prone areas creates a residual effect that hinders the growth of mold and algae; especially useful in bathrooms without ventilation, ceilings with condensation, and north-facing walls
- ✓ Interior and exterior — same product to treat stains on bathroom walls, kitchen ceilings, facades, exterior walls, terraces, and any surface with mold or grime
- ✓ Ideal preparation before painting — applying Humidity Stain Remover before painting in areas with a history of mold ensures that stains will not reappear under the new layer of paint; fundamental for lasting treatment

Mold stains or capillary humidity stains?
This product eliminates stains caused by mold, mildew, algae, and grime that develop on damp or poorly ventilated surfaces. It does not treat the cause of the humidity. If the stains are from capillary humidity (rising from the ground), leaks, or structural condensation, first treat the cause with Beissier's specific products for those pathologies and then use this cleaner as a preparatory step before painting.
