Mapei Adesilex P9 25kg Construction Adhesive - White

Adesilex P9 is a grey or white powder that, when mixed with water, forms a creamy paste with excellent thixotropic properties. It offers strong adhesion to various substrates, hardens without significant shrinkage, and has a pot life of over 8 hours with an open time of 30 minutes.

This adhesive can be used for bonding ceramic tiles and mosaics on floors, walls, and ceilings. It is also effective for spot bonding insulating materials like expanded polystyrene and is suitable for wet areas such as swimming pools.

The waiting time before grouting varies: for walls, it is between 4 to 8 hours, while for floors, it is approximately 24 hours. This allows the adhesive to set properly before applying grout.

Yes, Adesilex P9 should not be used on surfaces subject to extreme flexing or vibration, such as wood or fiber-cement. It is also not suitable for metal surfaces or installations requiring an adhesive thickness greater than 5 mm.

Adesilex P9 can be applied in temperatures ranging from +5°C to +40°C. Once cured, it can withstand temperatures from -30°C to +90°C, making it versatile for various environments.

The adhesive typically reaches its full strength after about 14 days. However, it is ready for light foot traffic after approximately 24 hours.

The consumption rate of Adesilex P9 varies between 2 to 5 kg per square meter, depending on the substrate and application method used.

Mapei Adesilex P9 is a high‑performance cementitious adhesive designed for bonding ceramic tiles and mosaics on walls and floors. It is suitable for interior and exterior applications, provides strong adhesion, and is ready to use with water resistance and non-flammability.

It bonds well to ceramic tiles, mosaics, and natural stones on substrates such as concrete, cementitious screeds, and anhydrite. It is suitable for interior and exterior use and tolerates typical substrate movements.

Key properties include high adhesion strength, long open time, fast setting, water and frost resistance, suitability for wet areas, non-flammability, and a white cementitious powder formulation supplied in 25 kg bags.

Under typical conditions, a 25 kg bag provides coverage of about 6 m2, depending on tile size, substrate flatness, and application method.

Follow the manufacturer’s instructions: mix the white powder with clean water to form a smooth, creamy adhesive. Use a suitable notched trowel to apply the adhesive to the substrate, then comb ridges as required for tile size and type, and press tiles firmly into place to ensure full bedding.

Grouting should be performed after the adhesive has reached its initial set and achieved sufficient bond strength. Environment conditions (temperature and humidity) affect setting times, so follow the product’s guidance for your specific job site.

Yes. Adesilex P9 is water‑resistant and frost‑resistant, making it suitable for use in wet areas and exterior installations where appropriate.
