Mapei Granirapid

Product Overview

Granirapid is a two-component tile adhesive composed of a special hydraulic binder and silica sand (component A) combined with a synthetic rubber latex (component B). It features extremely fast curing, excellent bond strength, very low shrinkage, and outstanding mechanical properties including resistance to impact, vibration, temperature changes, and ageing. Granirapid is particularly suited for projects requiring rapid completion and return to service.

Features

• Fast Curing: Light foot traffic possible within hours of installation, significantly reducing project timelines
• Deformable Formula (S1 Class): Provides flexibility to accommodate substrate stress from temperature changes or minor vibrations
• Excellent Bond Strength: Outstanding adhesion performance on a wide range of challenging substrates
• Low Shrinkage: Minimal shrinkage during curing, ensuring long-term stable tile installation
• Chemical Resistance: Good resistance to alkalis, oils, and solvents
• Low VOC Emissions: EC1 R Plus very low emission certified (per manufacturer data)
• European Standards Certified: Classified C2F S1 under EN 12004 (per manufacturer data)

Applications

• Fast-track installation of all types of ceramic tiles, porcelain tiles, and mosaics for interior and exterior use
• Natural stone (marble, granite, etc.) and artificial stone installation
• Reconstructed stone and stone projects requiring fast-setting adhesives
• Bonding rubber flooring on cement substrates
• Rapid renovation tiling in high-traffic environments (shopping centres, factories, hospitals, airports, etc.)
• Tiling over underfloor heating systems
• Overlay tiling on existing floors (ceramic tiles, natural stone, terrazzo, etc.)
• Swimming pool and basin tiling

Packaging

• White: 28 kg kit (component A: 22.5 kg + component B: 5.5 kg)
• Grey: 30.5 kg kit (component A: 25 kg + component B: 5.5 kg)

Important Notes

• Not suitable for substrates subject to severe movement or vibration (e.g., chipboard, fibre-cement board)
• Not suitable for metal surfaces
• Some natural marbles (e.g., green marble, sandstone, slate) are sensitive to moisture and should not be bonded with this product
• Component A contains cement — may cause skin irritation or allergic reactions on contact; wear protective gloves and goggles
• For detailed application methods, coverage rates, and technical parameters, please refer to the official product data sheet

Mapei Granirapid is a professional-grade fast-setting tile adhesive. It achieves light foot traffic readiness within hours of installation, significantly reducing project timelines. Compared to standard tile adhesives that require days before use, Granirapid is ideal for shopping centres, hospitals, airports, and other venues that need rapid return to service.

What Tiles Can Granirapid Be Used With?

• All types of interior and exterior ceramic tiles, floor tiles, and wall tiles
• Natural stone and marble
• Artificial and reconstructed stone
• Large-format tiles and heavy stone slabs
• Tiling over underfloor heating systems

FAQ

How does Granirapid differ from standard tile adhesive?

Granirapid is a two-component fast-curing tile adhesive. It allows light foot traffic within hours, far faster than standard adhesives. Its bond strength is also higher (C2F S1 class), with resistance to impact and vibration, making it suitable for high-traffic areas. Standard tile adhesives cure more slowly with lower bond strength.

Can Granirapid be used with underfloor heating?

Yes. Granirapid is suitable for tiling over underfloor heating systems. Its flexibility (S1 class) and fast curing properties effectively handle the expansion and contraction caused by temperature changes.

Why use fast-setting tile adhesive instead of standard adhesive?

Fast-setting tile adhesives like Granirapid are ideal for projects requiring rapid completion and return to service, such as shopping centre renovations and hospital maintenance where prolonged closure is not an option. Fast curing also reduces the risk of tile displacement during installation.
