Damon Spencer from United Kingdom kindly trialled Perflex Royal Grey matt epoxy tile grout. He is an incredibly skilled guy, works on exclusive projects around the country, Damon works on steam rooms, rasuls, and the jobs that seem kind of impossible to a lot of tilers. 

“You have got to look at it as how much does this room cost me to do..
£35 tub of normal epoxy which has to be mixed in one go, this does me say 3x3m room and half goes in the wash bucket and in the sponges, 8 sponges @£2 each and 4 white scourers £3 each, and all over ME!
Perflex x3 = 10% wastage, which you can save and use anyway ! 1 sponge and 1 scourer, not needed but just in case , NO MESS on me!"
 

"I personally think it should be a professional product used by trades."

"Believe me anyone who does epoxy grouting will gladly pay someone else to do it if possible so even if it did work out more expensive (it doesn't) it still saves you time and effort, which costs more." "I’m very impressed with the finish, it's more hygienic than standard epoxy id say and easier than the tile itself to clean where normally its the other way around..."

"Seriously think you're onto a winner”.
