Evening Gents,
Grout 3000 is softer than some grouts, mainly those that are based on a sand/cement type formulation. We have looked into this in great detail, as well as having the Grout 3000 tested as part of the EN13888 standards. The Grout 3000 is officially classed as abrasive resistant, i am pretty sure though that the test replicates foot traffic and that type of wear as opposed to its resistance to a sharp edge.
You can be rest assured that the Grout 3000 conforms to the requirements of EN1388 and meets CG 2 WA. It has become an extremely popular product and hand on heart I am only aware of one issue that we had when the grout was too soft for everyday use, we eventually found out that the home owner mopped the floor twice a day using Dettol detergent!! The floor was mopped within hours of it being grouted so the grout never got chance to fully cure.
For us, it's about trying to get the right balance of usability and ease of use versus fast curing and surface hardness. If we make the grout harder this compromises the workability, it can flash set on the tile and becomes very difficult to clean off. Agreed, the grout is softer than some other grouts but hopefully the ease of application and the long lasting end result make up for this.
Regards to all
