Tilemaster Flexigrout is a highly versatile, flexible, fast setting wall and floor grout, specially formulated using carefully selected cements and additives. Tilemaster Flexigrout’s flexibility makes it suitable for use in a wide range of applications, including for use on surfaces subject to limited movement and/or vibration such as underfloor heating systems. Tilemaster Flexigrout is suitable for grouting joints in wall and floor tiles between 3mm – 15mm wide. Tilemaster Flexigrout is suitable for use areas subject to prolonged or permanent wet conditions such as wet rooms and swimming pools. Tilemaster Flexigrout can be used internally and externally and it is unaffected by frost after setting. When mixed with Tilemaster Flexmaster Additive, the flexural properties of Tilemaster Flexigrout are enhanced, making it suitable for a wider range of substrates such as steel and fibreglass. WARNING: Coloured grouts can cause staining and/or scratching to certain tiles; we recommend that a test application is carried out prior to grouting. Avoid covering the tile in grout and work the grout into the joint covering as little of the tile as possible.
