Build Concrete Form for Tabletop

it might work i don't know i'm going to line the edges all the way around to make sure that everything's sealed and it gives you a round over edge then i'll use a caulking tool to give it that round over edge i'm going to flip this upside down lay it right in there align it exactly where i trace it out and i'm going to put a bead of silicone around it now why because the back side of this is actually going to be the top side when we flip it over and that's going to be the perfect seat including this little tapered edge here that's why i'm not flipping it the other way around let's put some sweat in [Music]
