Description Product Overview Mapei Mapeproof 1K Turbo is a single-component, solvent-free polyurethane surface membrane designed for moisture suppression and substrate consolidation. It cures through reaction with atmospheric and substrate moisture, forming a dense, durable barrier that limits moisture transmission through cement-based screeds. It is specifically designed for substrates with elevated residual moisture levels, typically up to 95% relative humidity, where traditional drying times would delay installation. Mapei Mapeproof 1K Turbo allows for early installation of resilient, timber, and textile floor coverings while improving the strength and abrasion resistance of the substrate surface. Key Features One-component, moisture-curing polyurethane membrane Rapid drying for fast-track flooring installations Moisture suppression up to approximately 95% RH Improves substrate strength and abrasion resistance Solvent-free, odourless, and non-flammable Very low VOC emissions (EC1 Plus) No mixing required – ready to use Suitable for use under timber, vinyl, and resilient flooring Applications Moisture vapour barrier for cement-based screeds Preparation prior to timber flooring installation Use under resilient and textile floor coverings Consolidation of weak or dusty substrates Fast-track flooring projects with high residual moisture Substrates not subject to rising damp Notes Ready to use – do not dilute Apply by roller, brush, or flat trowel Typical application in one or two coats depending on substrate Waiting time between coats: 40 minutes to 2 hours Loss of tack: approx. 30–40 minutes Set to light foot traffic: approx. 60 minutes Allow minimum 2 hours before adhesive application Do not apply on wet substrates or where rising damp is present Technical Information Technical Specifications: Type One-component polyurethane moisture barrier Consistency Liquid Colour Brown Density Approx. 1.20 g/cm³ Dry Solids Content 100% Application Temperature 5°C to 35°C Consumption 0.20 – 0.40 kg/m² per coat Coverage Approx. 50 m² per 10 kg (at 0.2 kg/m²) Loss of Tack 30 – 40 minutes Foot Traffic Approx. 60 minutes Waiting Time Before Adhesive 2 – 24 hours Application Method Roller, brush, or flat trowel Packaging 10 kg drums Shelf Life Approx. 12 months (sealed) This product is designed for professional flooring applications where moisture control and installation speed are critical. Its fast curing profile and moisture suppression capability make it suitable for both renovation and new construction projects.
