How to repair broken drywall (gypsum exposed)

1

The paper facing on drywall can tear off under a number circumstances, but it's never a major problem. Whether you pulled glue or old wallpaper off the wall, and some of the paper facing came with it, or you were over zealous in scraping off old texture, you'll be able to make repairs with joint compound and a drywall knife. Sometimes a surface layer of the paper facing comes off, leaving the under layer exposed, and sometimes the entire facing comes off, exposing the gypsum core. The repair isn't significantly different in either case.

Pull off as much loose paper as you can, but do it carefully to avoid increasing the area of the repair. One method to limit the amount of paper you pull off is to score around the repair with a sharp utility knife and pull off paper up to the score line.

Spread a thin layer of all-purpose joint compound over the torn facing with a 6-inch drywall knife. Scrape it flat, feathering the edges of the repair into the surrounding wall, and...

Plaster walls in older homes are often plagued by cracks and other defects such as pitting and uneven texture. If cracks are simply filled with spackling or joint compound, they have a tendency to telegraph back through. To solve this problem, apply self-adhesive fiberglass mesh drywall tape over the crack for reinforcement.

Cover the tape with several coats of joint compound to make the crack disappear. Mesh tape also helps prevent a ridge or “crown” from forming over the crack, as is often the case when traditional paper drywall tape is used.

If the walls have an uneven texture or are badly pitted, apply a thin skim coat of joint compound to the entire surface then sand the walls smooth.

To further enhance the look of the walls, an “orange peel” finish can be applied before painting. This is done by thinning the joint compound down and spraying it on the walls to even out any imperfections and give a textured...

So you finally got around to removing that paneling or tile and RIP! Off comes some drywall paper (also called facing) along with it. Now what started as a fun update project has turned into an annoying repair project. The damage isn’t deep, but it’s unsightly. So what’s the right way to repair it? Well, why don’t you ask us a hard question? We’ve tackled patching a hole in drywall, and this will be easier than that. How to repair torn drywall paper and patch it up is a Pro tip you’ll want in your back pocket.

Well That’s Not Tearable

1. Remove loose paper with a razor knife. You’ll surely have some ragged or hanging paper left from the tear, so use a razor or utility knife to remove it. The edges of the tear should be smooth against the wall.

2. Important: seal the exposed gypsum. The gypsum will absorp moisture from latex paints, so you must seal it to prevent blisters. You can use some drywall primer and sealer or...

Drywall Damage Discovered: A disaster?

There's only one thing as disconcerting as the unexpected discovery of a hole or damage to interior walls in an otherwise perfect home. The first ding or scratch in your shiny new car is a one-time event, but the supply of free holes lying in wait for drywall in any active family home is endless.

Because it is fire-resistant, drywall or gypsum board is now one of the most common building materials used in the interior of modern homes, and if only because it is paper-covered gypsum, a chalk-like material, it can suffer varying degrees of damage easily. The careless moving of furniture or active children at play with projectiles of any kind may result in gouged drywall; serious holes may be a result of that innocent hallway hockey game, a baseball, or simply tough and tumble kids.

Do you have beat-up drywall or gypsum board in the hallway that has been scratched beyond...

Wallpaper Preparation

Wallpaper Preparation

There are two reasons to prepare your walls before installing wallcovering. It ensures that your wallpaper will adhere correctly to the wall and it aides future removal. As wallpaper dries, normally over a 24 to 48 hour period, there is a significant amount of pull as the paper contracts. If the wallpaper has not formed a good bond, it will pull away from the wall. Additionally, when the paper is later removed, it may damage the covering of the underlying surface. Proper preparation will ensure the best results from your wallcovering.

Surface repair

The first step is to repair any defects in the wall surface. With drywall, any dents, nail holes, etc., should be filled with drywall patching compound. After the proper drying time for the particular compound you are using, the repaired areas should be sanded to leave a smooth, level surface. With plaster walls, any...

Occasionally I have to open a section of wall to make a repair, for instance to replace a section of broken pipe. It saves me a lot of repair and patching time if I can preserve the section of drywall and then reinstall it when the repair work is done. Furthermore, some texturing is fairly difficult to replicate. I find it much easier to just patch the joints and fastener holes than to try to blend an entire section with the rest of the wall.

There are two scenarios I typically encounter. The first is accessing a section of wall between two studs. The second scenario is where the area is wider than a single stud bay. In the first case, I locate the position of the studs and then cut the drywall just inside the stud. In other words, I cut through the drywall where it has no stud behind it. I then look for the edge of the other stud, in most cases about 14 inches over, and cut there. In order to prevent the piece of drywall from falling into the stud bay, I drive a screw part...

How to Install Drywall Guide


You are best being versed on the install since since the hanging of wallboard takes a little practice. You should know how the sheets are going to be installed on the walls along with the drywall layout. Have a screwgun ready with extra tips, and utility knife with extra blades.

Measuring, Marking & Cutting
Using a quality locking tape measure, transfer the measurement of the needed dimension onto a sheet of drywall, marking with a pencil (no ink) at the tapered edge of the board. Another way to mark is to snap a chalkline for lengthier cuts. But mark slightly less than the needed dimension since gypsum cuts tend to form a jaggy cut line, which builds the dimensional distance.

Place an aluminum 4 foot T-square on the mark to be cut and score the face of the drywall with a sharp utilty knife.

Then tilt the sheet, snapping it backward toward the score and exposing the cut through gypsum...

Um, pretend like the last post didn’t happen yet for a minute. Pretend like you didn’t already see the ceiling of my closet painted and finished:

Because today we’re blogging backward and rewinding a bit. I seriously don’t know what kind of operation we’re running around here… blogging the middle of things before earlier things. Where are the grownups in charge?!

This is what the closet ceiling looked like when we started this project: a rich, decadent popcorn ceiling texture, offset by the soft, glowing light of a fluorescent fixture. #Luxury

There’s nothing more soothing and uplifting than accidentally catching a glimpse of yourself mid-outfit-change in the floor-length mirror with all your “stuff” bathed in fluorescent light. (Shield your eyes!) That light had to GO.

But if you’re adding a chandelier, it needs to be centered in the room. And if you’re moving the electrical box, you have to patch the old hole, and if you’re patching the old...

You've seen them before, right? The silver-dollar-sized concave, or sometimes convex, circles on your drywall ceilings and walls? These are often called nail pops because the drywall nail or screw that fastens the gypsum panel to the wood studs or floor joists has “popped” a hole that you now have to repair.

The repair is not too hard, but there are a few steps you need to take if you only want to repair and repaint this area once. I've got a saying in my weekly AsktheBuilder.com newsletter that applies here: Do It Right, Not Over!

If you don't take the time to fix the core problem, no matter how many times you patch the nail pop(s) they'll come back like your unwanted relatives over Christmas.

Very few people have ever heard of "hydrous calcium sulphate." And even fewer are aware that hydrous calcium sulphate - CaSO4.2H2O as chemists know it - is gypsum, the rock that nobody knows.

In addition to being found in the Egyptian pyramids, gypsum rock is referred to in the ancient cuneiform scripts of the Assyrians. Its use was probably developed by the Greeks, whose influence certainly remains in the name by which the rock is known.
They called it Gypsos, the source of our word "gypsum."
Gypsum is a rock that, like limestone, occurs naturally in many parts of the world, and like limestone, in an absolutely pure form it is white. However, the usual presence of darker impurities produces rock in varying shades of gray, brown, and even black. Since it normally is found close to the surface, gypsum can be mined or quarried easily.

The biggest part of the gypsum rock used in this country goes into wallboard for homes. Gypsum "boards" are formed by...

Water damage and stains on drywall are usually the result of a leaky roof or plumbing fixture. Minor damage and stains can easily be repaired. When the damage is not severe enough to require the replacement of the damaged wallboard the following steps will lead you through the repair. The photo to the right shows a water stain but there was also loosened drywall mud and paint which is hard to see.

First make sure the drywall is still attached to the studs or framing. If the wallboard is sagging or broken it will need to be replaced. There may be blistered paint or loose layers of drywall mud but the wallboard itself is solid and secured to the studs. If the wallboard is sagging slightly try to snug it up using drywall screws. Start at the outer edge of the sag. Make sure the screws go into the studs and try not to break through the surface of the wallboard. Work slowly toward the worst part of the sag using the screws to pull up the board.

A torn area in a room's drywall facing looks hideous, but it's easy to fix when you know the right procedure. Just filling the area with joint compound will not correct the problem. The visible area of gypsum that lies under the drywall facing needs to be sealed to protect the gypsum and prevent the paper around the torn area from bubbling up when you repair the tear. Using the right method, you can make your wall look like new again.

1 Score the drywall approximately 1 inch from the tear, all the way around it. Remove the scored paper to create an even, crisp edge around the torn area to prevent any paper nubs from sticking out.

2 Seal the area -- the paper edges and the exposed gypsum -- with a coat of fast-drying oil-based sealer. Allow the sealer to dry completely before continuing. The sealer creates a protective surface between the exposed gypsum and the new layer of joint compound. It keeps water from penetrating into the gypsum. Other effective sealers include...

In Part one of this post we looked at clay-based plasters; now we’ll examine the other natural binders, all of which are different from clay in that they have a chemical set.

Gypsum

Gypsum is one of the oldest plasters, and because it can be cooked as low as 350 degrees Fahrenheit to create a binder, it is in fact among the most ecological. Gypsum is a soft, fairly common mineral that is formed when sulphuric acid (typically from volcanoes) reacts with limestone. It is carried in solution and deposited in layers on sea-beds, and over time it forms into a soft stone which we now mine. Chemically gypsum is hydrous calcium sulphate (CaSO4·2H2O), but when cooked at temperatures you would use to cook a casserole, three-quarters of the chemically bound water is driven off, forming 2CaSO4.H2O, which is moulding plaster (plaster of Paris), or gauging plaster – the latter is chemically identical, but is ground coarser to slow the set time. This is the most common form of...
