I just bought some latex on ebay its called tripple XXX its supposed to be the new wave in latex. Its supposed to be 3 times stronger with a thinner casting than the other stuff out there with a thicker pour. My question is I heard that the amonia smell is not supposed to be harmfull to breath in. But this stuff the amonia smell is so strong I poured my casting in a fairly large well ventaled room with a cleapo resperator on. And it was still so strong it took my breath away from me so much that I actually let the mold slip from my hands I couldnt be anywhere near it. It was a nightmare doing the casting and I puked 3 times with the resperator on. Will the amonia fumes cause any harm to your lungs or any other part of your body for that matter. Im ready to dump the rest of this stuff in a swamp.
