Masking Corners to Paint Walls

"We are now going to discuss putting tape on the corners and making sure that you have a good crisp line. So we are going to start back wherever your wall begins and you are going to go ahead and run your tape like we have done earlier. Once you get into this inside corner, you are going to want to get it all the way back into the wall. Make sure that you keep it tight so you get a nice tight seal. You are going to want to take a puddy knife put it right on the lip for your base on your opposite side and then pull your tape. What that would do is it would give you a good crisp perfect line when you go to paint that. So on your next side, you go ahead and start by a 1/8 or a 1/16 side of that corner. You should have a corner that you had just before you painted it. Now it would be painted with the colors of each and not variations."
