Self levelling epoxy

[Blackrat]

you can use laminating epoxy, you must just get the slowest hardener they have ... if they have ATH you can mix some of that in 30%ATH and 70% epoxy , this will make the epoxy less likely to crack

make sure you clean the surface with thinners / acetone after washing with soap and water

Thanks too much, after hard search find some new resins, ones used for Domes (Epoxy Domes) https://www.google.com/search?q=epoxy+domes&tbm=isch - These have viscosity resin 10000 - 12000 mpa and hardener 400mpas. These come without solvent and harder in like 24 hours. Looks like glass
and found another similar that can be used with additional stuff like sand/quartz/carbonate maximum 100% of weight- viscosity resin 1375 ~ 1625 mpas and hardener 600-700 mpas.

Cost is like 36USD each KG

Another option is to use 3/4" natural granite. SOmeone know if is possible ? i can make the structure from welded steel and then attack some pieces of Natura Granite to get flat surface.
