FAQ
What is Trufix 440 Grey?
Trufix 440 Grey is a premium, high-performance, polymer-modified, grey cement-based tile adhesive designed for fixing a wide range of tiles on interior and exterior floor and wall substrates. It provides superior bonding strength, excellent flexibility, and enhanced water resistance, making it suitable for demanding applications and large format tiles.
What are the key features of Trufix 440 Grey?
Trufix 440 Grey is a grey-colored, thin-set, cement-based tile adhesive with advanced performance characteristics, such as:
- Superior bonding strength and shear resistance
- Excellent flexibility and deformability
- High sag resistance for vertical applications
- Extended open time and adjustability
- Enhanced water resistance and durability
- Compatibility with a wide range of tile types and sizes
- Suitability for demanding substrates and environments
What are the advantages of using Trufix 440 Grey over regular cement tile adhesives?
Trufix 440 Grey offers several advantages over regular cement tile adhesives, such as:
- Higher bonding strength and improved adhesion to various substrates
- Greater flexibility to accommodate substrate movements or deflections
- Reduced water absorption and increased water resistance
- Extended open time and adjustability for easier installation
- Improved resistance to thermal variations and freeze-thaw cycles
- Enhanced durability and long-term performance in demanding conditions
- Suitability for large format tiles and challenging installations
What substrates can Trufix 440 Grey be used on?
Trufix 440 Grey can be used on a wide range of stable, dry, or damp substrates, including concrete, cement screed, cement backer board, brick masonry, cement plaster, gypsum plasterboard, and existing ceramic tile or natural stone surfaces. It is also suitable for use on heated floors, swimming pools, and exterior facades.
What tile types can be fixed with Trufix 440 Grey?
Trufix 440 Grey is compatible with a wide range of tiles, including ceramic, porcelain, vitrified, mosaic, glass, and natural stones like marble, granite, and limestone. It is particularly recommended for large format tiles, thin tiles, and tiles with low water absorption.
How is Trufix 440 Grey mixed and applied?
Trufix 440 Grey is mixed with clean water in the ratio of 4.5-5 parts of powder to 1 part of water by volume to obtain a lump-free, creamy consistency. The adhesive is then spread on the substrate using a notched trowel, and the tiles are pressed firmly into the adhesive bed, ensuring complete coverage and a uniform thickness.
What is the recommended notched trowel size for applying Trufix 440 Grey?
The recommended notched trowel size for applying Trufix 440 Grey depends on the size of the tiles and the substrate condition. For tiles up to 600 mm x 600 mm, use a 12 mm x 12 mm square-notched trowel. For larger tiles or uneven substrates, a larger notch size or a back-buttering technique may be necessary to ensure proper coverage and support.
What is the open time and pot life of Trufix 440 Grey?
Trufix 440 Grey has an extended open time of approximately 30-40 minutes at 30°C, allowing more time for installation and adjustments. The pot life of the mixed adhesive is around 3 hours at 30°C. Do not add more water or use the adhesive beyond its pot life.
How long does Trufix 440 Grey take to set and cure?
Trufix 440 Grey sets in 24 hours and achieves full bond strength in 14 days at 30°C and 50% relative humidity. The tiles can be grouted after 24 hours, and the tiled area can be subjected to light foot traffic after 48 hours. Protect the tiled surface from water exposure and heavy loads during the curing period.
Is Trufix 440 Grey suitable for use in swimming pools or external facades?
Yes, Trufix 440 Grey is highly water-resistant and suitable for use in swimming pools, water tanks, and external facades exposed to weather conditions. Its superior bonding strength, flexibility, and durability make it ideal for demanding applications subject to thermal variations, vibrations, or movements.
