Rust-Oleum 5090 Anti-Condensation Coating – Hygienic Moisture Control for Damp Areas

Rust-Oleum 5090 Anti-Condensation is a water-based, single-pack hygienic topcoat that helps prevent condensation and dripping caused by discontinuous steam or water vapour. Ideal for kitchens, breweries, washrooms, and shower rooms, it actively absorbs moisture—with just 1 litre able to hold at least 400 grams of water after drying. Quick-drying and suitable for slightly damp surfaces, it’s the smart solution for maintaining clean, dry, and safe interior spaces.

Key Features:

• Prevents Condensation & Dripping – Absorbs moisture before it collects
• Ideal for High-Humidity Areas – Use in kitchens, breweries, and washrooms
• Absorbs Over 400g of Water per Litre – High moisture absorption
• Fast Drying Formula – Speeds up project completion
• Water-Based & Easy to Apply – Suitable for slightly damp surfaces
• Hygienic Topcoat – Improves cleanliness and safety in wet areas

Application Details:

• Surface Types: Interior walls and ceilings in humid environments
• Water Absorption: 400g per litre (after drying)
• Base Type: Water-based
• Application Conditions: Can be applied to slightly damp surfaces

Surface Preparation

New concrete or brick surfaces should cure and dry for at least 30 days prior to application
of the coating. Repair surface defects of (coated) concrete or brick surfaces. Remove grease, oil and all other surface contaminations by alkaline or high pressure (steam) cleaning. Scrape and wire brush carefully to remove deteriorated coatings. Sand previous coatings which are in good condition to remove gloss and to roughen the surface slightly. The surface may be slightly damp during application.
