Epoxy resin flooring? Yay or Nay?

[imayhavelostmymarbles]

Hi. We are building an extension to the back of our house to make a large living space.
It will have underfloor heating as we are looking at installing an air source heat pump and I have been looking at flooring.
A resin floor sounds amazing. The pics i have seen look amazing. So is it really?
What are the pros and cons?
Thanks

We had a large amount of epoxy resin flooring in our last house. We also had underfloor heating.
I loved the warm Matt continuous look of it, but it came in a limited amount of colours, they were fine but not 100% the choice I would have liked to of had. We ended up with a biscuit/beige colour all through the ground floor and a light grey in the bathroom.
The downstairs showed dirt very easily and marked and scratched over time, we didn’t mind it building up a patina, but if you like super clean looking floors it’s hard work.
The installation process is quite lengthy involving a base coat that needs to have a fine grit sprinkled on to it, has to be left to dry, can’t remember how long but I think 24 hours, then the latex is poured over the top, think that was 2 days drying, then it had a sealant/varnish 2 coats again more drying time, we used a specialist company and it cost a lot.
You obviously need to be able to keep the space free of any people/trades during the laying process, so it’s quite disruptive to a building schedule. It was also in our kitchen diner, so the kitchen was fitted after the floor was all done and dried.

These show the floor colours

Thanks. It looks great but I was thinking it would be a more cost effective solution as screed has to go down on top of floor heating coils anyway.
I am put off by the thought of it being a bit rough. I don't want a "gritty" floor finish.
Back to the drawing board!

@imayhavelostmymarbles no it’s not rough, it’s completely flat and smooth, but they have to put an undercoat and grit on first, for the resin to bond to, the resin is then poured on top and it’s completely smooth.
The only reason I mentioned the undercoat part was to make you away that there are several stages to the process which obviously have time implications, I think that’s what puts some people off because they don’t want to have several days where nobody can enter the space.
