How To: Bend Drywall

In curvilinear rooms, or in situations like an arched doorway, you can bend drywall using this tried-and-true technique of the pros.

Here’s a tip on how to throw a curve with drywall. The trick is to use two sheets of quarter-inch drywall instead of one standard half-inch sheet. Hose down both sides of each panel and form it to the curve, fastening with nails or drywall screws. Do the same with the second sheet, then tape and finish.

Quick Tip: Installing Beadboard Wainscoting

Beadboard wainscoting is as attractive today as it was in the 19th century, and it still does a great job of protecting walls from dings and dents.

To achieve a Victorian look on an interior wall, try a beadboard wainscot. You can buy beadboard at your local lumber yard. Here are some things to keep in mind when installing it yourself. Run your baseboard first to avoid creating a dust collector. Use a drill and a jigsaw to cut holes for outlets. Fit each board together snugly, then nail with 2-1/2-inch finish nails. Angle the bottom nail into the tongue of each board. Base nail the top and cap it with the molding.

Quick Tip: Custom Moldings

Give character to dull bland spaces through the use of custom moldings, whether baseboards, chair rails, or any other type.

Dress up the rooms in your house with a variety of custom moldings. These moldings are available in many historic profiles. You can add a one-piece baseboard molding for a 19th-century look, while popular cherry rails and picture moldings add detail and take paint well. And for a more elegant look, add a multi-piece crown molding to the ceiling.

What Would Bob Do? Cutting Drywall

With the right tools and technique, you can cut drywall cleanly and keep the dust level under control.

How to Cut Drywall


I’ve got to remove some drywall in a room so I can nail studs behind the wall for anchoring purposes. What is the best tool for cutting the drywall?

If for any reason you want to cut drywall that has already been installed—for a nailer (blocking), say, or recessed lighting—the name of the game is minimizing dust. The jab saw is often the tool I recommend, because not only does it generate less dust than a power saw, but it allows you to closely control the cut so as not to disturb electrical work and plumbing behind the wall. As you work, use your free hand to follow the cut line with the nozzle of a shop vac. Further minimize dust by fitting the jab saw with a metal-cutting blade, which has fine teeth that won’t remove as much material as a comparatively coarse standard blade. Let the inside face of the stud be a guide for your cut; once the cut has been made, follow up with a utility knife, using the precision tool to smooth out any irregular edges.

When you’re cutting a drywall panel prior to installation—or when patching a damaged section—your best bet is to use a utility knife in combination with a 48-inch drywall square. With the square, mark your cut lines, then score them with the utility knife, going deep enough to slightly pierce the gypsum core. Next, snap the panel along the scores you’ve made. What remains now is the drywall face paper on the side that you didn’t score, but at this point in the process, you should have no trouble cutting it away, once more using your trusty utility knife. Avoid tearing the paper, particularly if your project is going to involve taping drywall seams. To make any minor, final-stage adjustments to the panel or patch you have cut, use a rasp to grind the drywall down to the dimensions desired.

How To: Build a Cement Block Wall

Cinder block wall building is a project that can be managed easily even by the beginning do-it-yourself.

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 butter 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 flush end of the next, allowing three-eighths of an inch for your mortar joint. Finally, check for level.

Quick Tip: Installing Crown Molding

Often the most challenging aspect of installation is to cut the crown molding so that it fits snugly between the walls and ceiling. For professional-looking results, follow these guidelines.

You can dress up a room by installing crown molding along the ceiling. Here are some tips to keep in mind. Always place the molding in your miter box upside down. Think of the box as if it were the ceiling. Then trim the back of the miter at a 45-degree angle with a coping saw. This way, you should have a perfect fit. Add a coat of trim paint, and you’ll end up with a much more elegant room.

Concrete and Cement: A Case of Mistaken Identities

Let's review the "concrete" evidence and clear up the confusion once and for all.

Concrete vs. Cement


It’s an old cliché of the Mafia: A fellow gets on the wrong side of La Cosa Nostra only to wind up wearing cement shoes at the bottom of a river. Well, those shoes may be made of cement, but little else in the world is composed of cement and cement only. Concrete, however, is everywhere. It’s even in the large, rotating drums of those ubiquitous vehicles we inaccurately refer to as cement trucks. It’s not surprising that people are always mixing up these sedimentary mixes, but while they look alike and behave similarly, solid differences exist between the two.

Cement vs. Concrete
Here’s one of the main reasons cement and concrete are so often confused: There is cement in concrete. That’s right, when cement is blended with water, it creates a paste. And when that paste is combined with aggregates like gravel and sand, the result is what we know and love as concrete. Cement itself is made from calcium and silica-rich materials, such as limestone and clay. Its unique adhesive properties make it an excellent binding agent, but on its own, cement is prone to cracking. Compared with concrete, which can last hundreds of years, cement is much less durable. To use an analogy, cement is to concrete as milk is to ice cream. Sure, ice cream has milk in it, but it isn’t milk. It’s actually much better.

Cement vs. Concrete - Tools


Using Concrete and Cement
One of the strongest and longest-lasting materials known to man, concrete is used to build schools, bridges, sidewalks, and countless other structures. But you don’t need a hard hat to have success with concrete. Amateur handymen use it for DIY projects of all kinds, among them landscape edging, kitchen countertops, and front walkways. Cement, by comparison, is used mainly in smaller jobs (for example, grouting and specialized masonry) and in the repair of cracked or crumbling concrete.

Concrete and Beyond
Complicating matters further is the fact that you can buy dozens of different kinds of concrete. Each type responds to the demands of specific applications. For example, fiber-reinforced concrete, which resists cracking even under immense loads, ranks as a common choice for driveways. There’s also fast-track concrete, employed when time is of the essence. Before purchasing any concrete, be sure to consult with an expert or do a bit of research so that you understand the pros and cons of all the options available.

How To: Remove Plaster

In the process of removing plaster walls, these guidelines can help you complete the job safely and effectively.

Here’s how to remove old plaster when starting a remodeling project. Have professionals remove any old electrical connections and gas piping. Wear eye protection, mask, and gloves. First, remove the plaster using a flat bar, then remove the old lath with a hammer. Haul out the plaster and bundle up the lath for efficient disposal.

Quick Tip: Drywall vs. Blueboard

Although these popular wallboard options are often discussed interchangeably, important differences exist between drywall and blueboard.

When choosing wallboard, remember the difference between drywall and blueboard. Drywall panels are covered with paper that will take paint directly, once they’ve been taped and the joints and fasteners have been covered with compound. Blueboard’s more absorbent paper layer is designed to bond with a veneer plaster coating before it’s painted.
