computer-generated transcript - may not be 100% accurate
" Hi, I'm Bob Vila from home again. Here's how to lay out a cement block wall yourself. Mix two parts masonry cement with one part sand and add just enough water for a firm mortar mix. Then batter all webs and the sides of each block using the top part of your trowel. Stagger your joints and place the open end of one block to the flash end of the next, allowing 3/8 of an inch for your mortar joint. Finally, check for level. I'm Bob Vila. Good luck with your improvement project. "
