treesner Posted April 3, 2017 Report Share Posted April 3, 2017 do you guys have a recommendation on what type of resin to buy if I want to do a table top that has elements on the bottom but get covered up and flat top. I'll need to buy a very large volume of it example of type of thing i mean I imagine i'd want the 'casting resin' like this opposed to just normal resin? In one of the videos i watched the guy recommended polyester resin because it's cheap (although it smells horrible). There's also polyurethane resin but needs to be done in a moisture free area. found this quote in an article: "I use epoxy for everything unless I am trying to cast something larger that I want to have a shiny gloss finish. In that case, I use polyester because I can polish it on my buffing wheel instead of using the gloss sealer spray or coating with another layer of resin. If I lived in a less humid environment (like the desert), I would definitely do more with polyurethane resin as I suspect I could work with it without needing a dehumidifier."

wtnhighlander Posted April 3, 2017 Report Share Posted April 3, 2017 Probably casting resin. As I recall, it is a harder material than polyester resin. Polyester is sometimes used in place of epoxy resin glassing wooden boats, and I've heard pros and cons for both, but polyesther is supposedly more flexible / softer. If you are embedding objects with a lower specific gravity than the resin, be sure to glue them to the substrate first, or cast the thing upside down, so the side the embedments float up to becomes the bottom.

ChrisG-Canada Posted April 5, 2017 Report Share Posted April 5, 2017 I use West System Epoxy and it's anything but soft when it's cured! Maybe other types of epoxies can be soft, but in my experience the West System kind gets very hard and durable. Quote Link to comment Share on other sites More sharing options...
