Hi,
OK, I looked at those three brands. All appear to have suitable products but I am drawn to the Ultra FlexJoint as it specifically states its suitable for 1mm and has a "super fine texture"
Ultra FlexJoint: Specially designed for areas where movement or vibration is likely to increase flexibility and to provide a virtually impermeable set. Allows for joints up to 20mm to be grouted in one application. Suitable for use with most common
tile applications including natural stone, porcelain, conglomerate and ceramic wall and floor tiles. Classified CG2.Available in white, cream, limestone, sandstone, chocolate, grey and anthracite. 1-20mm joint widths. Kitchens, bathrooms, swimming pools, power showers etc. Water repellent. Internal & external. Anti-fungal. Mould resistant. Polymer modified. Hygienic. Under floor heating. Super fine texture
Tilemaster Grout 3000 is a highly versatile wall and floor grout specially formulated using carefully selected cements and additives to provide a smooth, creamy, controlled workability. Grout 3000 is flexible and is suitable for use on surfaces subject to limited movement and/or vibration such as plywood overlay, plasterboard and under floor heating. Grout 3000 is suitable for grouting a large variety of wall and floor tiles with joint widths between 2mm and 15mm wide. Grout 3000 has very low permeability making it ideal for use in areas subject to prolonged or permanent wet conditions such as wet rooms and swimming pools.
weber joint pro is a scratch-resistant, water-repellent, flexible
tile grout for interior and exterior use in situations where some movement or vibration is expected. Suitable for joint widths up to 10mm. Can be used on walls and floors. Water-repellent surface for reduced water penetration and improved resistance to staining. Limited flexibility to absorb movement from wooden floors or underfloor heating.
Anyone disagree with the Ultra option?
And does anyone know of a stockist in Hampshire (Farnham area) I can't find anyone via Google.
Thanks for the input chaps!
