Reinforce Seams and Mask Baseboards

So now I've got nice tight plastic. Same thing, I come over here, got a little excess. Roll it up, tack it down. Roll it up, show you over here. Stretch it out, get it to seal, roll it in. Just like this, fill that in. Before I get off my ladder, so don't have to get up on it a second time. Got my seam, tack it on the tape. Fill my seam, just like that. Leak is gone. Ladder goes to the upside of the door, get rid of my tape. There, roll it, roll it, roll it. All the way down. Now I want it tight on the bottom. Roll it all in. Don't want anything flopping in the wind down there. Bam, done. Right there, opposite side. Pull your tape if it flopped onto the trim. Get it underneath, roll it, get it underneath. Roll it, get it underneath. Roll it, get it underneath. Roll it, get it underneath. Bam, done. But I want to take and sure, no leaks. Tighten it up at the bottom. No leaks. Tighten it up at the bottom. Just like that. It got baseboards exposed, fill it in. So we don't have any leaks. Get a nice sharp line. Put press it in the corner, wrap it around. We're going to tack that down. Come up over the top, tack it. Leaks gone. Leaks gone. Bang, all leaks. Make all leaks go away. Got, right here this can flap up. Don't want any paper kicking up when you're spraying. It's tight. This could actually flap up. Press seal it down. Good to go. Now this room is all ready to spray. That is how you mask a door jam.
