Repairing a Bad Epoxy Pour

What happens here

Immediately after spreading the epoxy, use a propane torch to lightly and evenly pass over the entire surface. This heat from the torch will cause any air bubbles trapped in the epoxy to rise to the surface and pop, resulting in a smooth, glass-like finish. Pay close attention to any visible bubbles, and also run the torch along the sides of the countertop where bubbles commonly form. Do not hold the torch in one spot for too long, as this can scorch the epoxy or create uneven curing. Continue to 'baby-sit' the slab for the next few hours, re-torching if any new bubbles emerge, until the epoxy begins to set.

Goal: Eliminate air bubbles from the epoxy surface for a smooth, clear finish.

woody [Music] so immediately after the pour we went right into the torching part process and what i'm doing is just touching up if i got any if i noticed anything so getting down here and eyeballing it to get right at the same level as any bubbles and uh kind of catching any imperfections and if i'm noticing any dirt or dots i'll dot them out because i can still fix them at this point [Applause] this will be the thumbnail dan give me that thumbnail right there the ending just thumbnail [Music] [Applause] so i went to 240 frankie i did not go to 400 grit you didn't do the 400 though nope nope they say 220 so i figure if i went 240 yeah i went i went x3 as it is [Applause] so now basically it's a matter of just babysitting this slab to make sure no bubbles come up and if they do then just touch them with a torch before they become permanent it's a matter of catching it at this time [Applause] but now a report like this actually adds depth to the um [Applause] because the thicker you go the better the results come out look at that frankie i don't know if there's anything to touch up dude [Applause] she's about as we do have to torch the sides as we do this just because bubbles will form on the sides it will run a little bit more when you get light up the torch because you're warming up the material this is where you gotta get down let's check for bubbles all right two more to go [Applause] now these are virgin coats so i'm gonna use a lot more material this is gonna be the first coat for these two all right it's time to pour the mantle this is where we get it over all the ends we brush on the ends whiskeys [Music] all right you guys let's take a close look at what we're trying to find before it becomes problems that see this little row of bubbles there those those all got to be eliminated a little bit right there so instead of using a torch with a lighter i don't like heat guns i like torches better because the heat gun moves the material around more it's got more air pressure on it for some reason i don't know why this just concentrates on popping bubbles one of the things guys don't leave the torch in one spot very long at all it doesn't take bubbles that's it
