7. When painting "new" walls, or walls that contain freshly hung drywall, remember that they will soak up a lot of paint. Make sure you have more than you think you'll need before you start so you don't run out mid-job. This is especially true if you choose not to use any primer. Although the homeowners in this episode chose not to use primer in order to save time, it is recommended that primer be used when painting raw drywall because it will give the paint better adhesion, it saves paint (which is more expensive than primer), and provides richer colors. 8. When cutting a full-sized wall into a half wall: first, make sure to reinforce the bottom part of the wall that will become the half wall. You can do this by taking some spare two-by-four pieces and running them horizontally across the studs of the lower part of the wall and nailing them in place on the stud boards. Make sure that each two-by-four stretches across at least two (ideally more) of the studs to help support the wall once you cut it in half. This is because once the top half is removed, there will be nothing other than drywall to hold the wall up and drywall is not strong enough to do this entirely on its own. You might demolish more of the wall than you bargained for if you don't complete this easy preventative step.
9. Before you begin laying a wood or bamboo floor, be sure to clean off your sub-floor entirelymaking sure to remove all drywall and dried mud chunks until you have a smooth starting surface. This is to prevent bumps and unevenness in your floor after it is laid. Once this is done, you can put down an "underlayment" right on top of the sub-floor for the wood/bamboo to sit on. This prevents the two hard surfaces from fitting right on top of each other. There are different kinds of underlayment, but it is usually made of foam or cork or another somewhat soft material and is used primarily to dampen the sound when walking on the finished floor. It should prevent squeaking later on and will very slightly soften the feel of walking on the hard floor. Using a good underlayment has even been known to help smooth out minor imperfections in the sub-floor, providing a smoother base for your wood/bamboo to sit on and making your floor look professionally done.
10. You can avoid using screws when attaching your sub-floor by using wood glue in a caulk gun to glue down the plywood pieces to the floor joists. In doing this, you only need to use nails instead of screws to fully secure the sub-floor. By using a nail gun to sink nails into the joists after glue has been laid, you can truly save yourself a lot of time using this method. Putting a layer of glue down also helps to prevent squeaking later on as the floor pulls up from the joists. If you don't use glue, you should definitely use screws to attach the plywood to the joists. You could also use glue and screws but this is commonly considered "overkill."
