Table Top Epoxy - 1 Gallon USA Made by MAS

You can certainly thin it with denatured alcohol or acetone up to 5% (95% epoxy resin 5% solvent) thinning can reduce the mechanical and physical properties though, a lot of people will simply warm up part A prior to mixing in part B to reduce the viscosity and improve the flow. You can take the jug of part A, make sure the cap is on tightly and place it in a bucket of hot water. Keep in mind the warming the mixture will cause the chemical reaction to kick off a lot sooner and the working time will be reduced.

It can certainly but used outdoors, however a few clear coats of a high quality UV-Spar Varnish or Bristol Finish, will be needed to protect it from the UV Light which will cause it to yellow, turn chalky and degrade.

MAS Table Top is not FDA approved for direct food contact. To our knowledge, no manufacturer is selling a FDA approved epoxy resin system.  Some manufacturers may claim "FDA complaint", "meets FDA guidelines", etc. - this is not the same as FDA approval.  These are largely marketing claims that have not necessarily been substantiated.  That said, we’ve made many table/bar tops with our product and personally feel comfortable if the tabletop incidentally contacts food (like dropping and being picked up), but we wouldn’t use it to coat a food prep surface where the food will have direct and continuous exposure.
