Hi,

I'm a DIYer, and looking forward to starting a project.

Been researching epoxy grout, such as Mapei Kerapoxy, Ardex WA, Laticrete SpectraLOCK ...

But worried epoxy based grouts will look shiny, too much like plastic or silicone sealant.
I've only seen limited pictures online, so interested in a experienced take.

Which products are the most matt, have the least sheen, the most powder like texture? ... generally look the most convincing?

Thanks

Chendy
