Kair Surface Cleanser Concentrate
Kair Surface Cleanser is a professional-strength biocidal wash designed to clean and prepare walls, ceilings, and surfaces affected by mould or mildew. Supplied as a 250ml concentrate, it’s ideal for use before redecorating with Kair Anti Mould Paint or applying other mould control treatments. This cleanser helps ensure that mould and fungal spores are removed at the root, stopping regrowth before it starts.
Product Features
Removes black mould, mildew, and biological growth
Water-dilutable concentrate (1:19 ratio)
Suitable for walls, ceilings, wallpaper, and hard surfaces
Prepares surfaces before using anti-mould paints
Fast-drying with biocidal action
Easy to apply by sponge, brush, or cloth
General Product Information
Kair Surface Cleanser is formulated to cleanse surfaces prior to decorating or wallpaper removal. It breaks down organic contaminants and destroys residual spores, helping to prevent mould from returning beneath the final paint layer. Recommended as a key step before using Kair Mould Eradication Additive or Kair Anti Mould Paint.
Energy Efficiency
Helps preserve the performance of thermal insulation and coatings by removing moisture-retaining contaminants that reduce wall breathability.
Health Dividend
Reduces mould spores that can trigger allergies, asthma, and respiratory irritation. Promotes a hygienic indoor environment and prevents hidden fungal growth
How It Works
The solution is diluted and applied directly to the affected area. The biocidal ingredients actively neutralise mould, bacteria, and algae. After drying, the surface is safe to decorate with Kair anti-mould solutions.
Control
Once cleaned and dried, the treated surface becomes a stable base for further anti-mould products. No active monitoring or further cleaning is needed until next redecoration.
Installation Instructions
Mix 1 part concentrate with 19 parts clean water
Apply using sponge, cloth, or scrubbing brush
Allow to dry fully before painting (1–4 hours typical)
In heavily affected areas, a second wash is recommended
Do not apply acidic cleaners before or after use
