Requirement of tile joint grouting product

There is Indian standard for stating the minimum requirement for chemical resistant grouting mortar material – IS 4389. Whereas, BS EN 13888 talks about the requirement of cementitious and epoxy grout used for tile joints. Here in this blog, we discuss about the BS EN 13888.

Standard BS EN 13888, specifies the performance requirements for cementitious and reaction resin grouts for ceramic tiles.

The basic or fundamental specification for the cementitious grout shall be as follows:

The additional specification for the cementitious grout shall be as follows:

 

The basic or fundamental specification for the epoxy or resinous grout shall be as follows:

  

For epoxy or resinous grout, there is no additional specification. But, some test like Flexural strength after freeze-thaw cycles, Compressive strength after freeze-thaw cycles, Water absorption after 30 min.. are not required to test.

Based on the strength parameters, both Cementitious Grout (CG) and Resinous Grout (RG) can be given class as follows:
