Ceiling Repair Basics
Whether due to normal wear or water damage, ceilings need occasional repair. Taking care of these issues quickly will help prevent them from becoming bigger problems in the future. Contact Ceiling Repair Perth now!
Ceilings in older homes may be constructed from lath and plaster, while newer houses have them made of plasterboard. Hairline cracks are usually cosmetic and can be corrected with drywall mud patching, while long lines suggest a structural issue that needs to be addressed.
Drywall is a construction material that covers the studs of interior walls and ceilings. It was introduced in the mid-20th century and replaced plaster as the main building material for new homes. It consists of gypsum powder compressed between hard paper sheets. The gypsum gives it stability and rigidity, while the paper provides a smooth surface for painting.
Dry drywall is also known as gypsum wallboard, GWB, wallboard, or plasterboard. It can contain additives to enhance its functionality, such as fire retardant, mold and mildew resistance, and sound absorption.
During installation, installers conceal the seams between drywall sheets with joint tape and apply layers of drywall compound, or “mud.” After the mud dries, it is sanded down to a smooth finish. This process can be time-consuming and difficult to perform correctly.
It is possible to repair small holes or dents in drywall with a little effort, but larger holes require professional attention and the use of special equipment. A professional will cut out a larger hole and replace it with a piece of drywall, patching the screw holes with a drywall patch, then filling and covering the holes with mud, or joint compound, and sanding to smooth the repaired areas.
In a bustling city like NYC, the ebb and flow of everyday life can take a toll on interior surfaces, manifesting in cracks, dents, and other damage that requires drywall repair. The unique challenges of urban living, from navigating narrow brownstone stairways to coordinating repairs in high-rise condominiums, demand the expertise of skilled artisans to restore interior spaces to their original splendor.
The most common source of drywall damage is moisture. The gypsum core of drywall is susceptible to moisture, which can cause it to rot and dissolve into a gooey paste that is food for mold. The organic binders and additives in the paper facings of drywall can also support microbial growth. This is why it’s critical to select greenboard, a type of drywall that is waxed and chemically treated to resist microbial growth, for rooms expected to experience high humidity levels.
Joint Compound
Choosing the right putty for a job can be tricky, especially when two products appear to have the same intended use. Although spackle and joint compound seem similar to the untrained eye, their differences in formulation impact factors like dry time, shrinkage, and project scope. Knowing what each product is used for and how they differ can help you tackle repair jobs with confidence.
Drywall mud, or joint compound, is a gypsum-based paste used to seam and smooth new drywall installations. It’s also useful for repairing cracks and holes in existing drywall and plaster surfaces. Joint compound can be purchased premixed in 1-quart to 5-gallon containers or as powder you mix with water. Typically, it takes about 24 hours for joint compound to dry completely and be ready for sanding and painting.
For large drywall repairs, a drywall patch kit may be an easier and more effective alternative to joint compound. These kits usually include a self-adhesive mesh reinforcement tape and a 12-inch taping knife. Apply a first coat of the compound over the tape, spreading it evenly with the knife or a drywall spreader. Feather the compound out 5 to 6 inches beyond each side of the tape, using long strokes.
When applying a second coat of compound, use more pressure on the putty knife to spread it evenly. Use a sanding sponge or sandpaper to smooth the surface of the compound, making sure to remove any rough spots. Allow the second coat to dry for 4-8 hours, then sand again until smooth. After sanding, wipe away any remaining dust particles and reapply a third coat if necessary.
Lightweight joint compound, which has a lower sanding tolerance and more sandable than regular joint compound, can be painted in as little as 24 hours. This type of joint compound is often used for painting over taped drywall joints, and it is ideal for projects where the joints will be covered with other wall coverings or trim. Some lightweight joint compounds have special additives to reduce dust production, such as attapulgite, expanded perlite, or ethylene-vinyl acetate polymer.
Joint Tape
The joint tape that covers the seams where drywall sheets meet on a wall or ceiling is the most critical component for creating smooth, strong and durable drywall. It hides the joints from view and enables the plasterer to create an even surface that’s ready for finishing. It’s important to use the right type of tape for the job, and there are several different types available.
Paper tape is typically used for interior walls, though it’s sometimes also suitable for ceilings. It’s very thin, making it ideal for achieving a seamless appearance. It can be purchased in rolls of 2 in. or 2-1/2 in. wide and 300 ft. or 500 ft. long, and comes in two varieties: self-adhesive or non-adhesive. Paper tape has good strength and is able to withstand some flexing, but is more susceptible to stretching or cracking than fiberglass mesh tape.
Fiberglass mesh joint tape has gained popularity in recent years, as it has an open-mesh design that allows the compound to penetrate and bond effectively. It’s generally not as thin as paper tape and is more resistant to stretching or cracking, but it can be prone to bubbling or wrinkling, particularly in high-moisture conditions.
Some installers wet the tape first by running it through a bucket of water to improve its stickiness and reduce the risk of lifting or flaking. Others simply apply the compound directly over it, using a minimum of three thin coats.
When working with inside corners, try to make sure that you cover the entire corner bead rather than just a small section near the edges of the wall. If you don’t, the resulting corner might be too sharp and will be difficult to blend with the rest of the wall.
It’s easier to apply a drywall patch or spackling compound to a hole than to the seam between 2 drywall sheets, but you’ll need a large enough drywall knife for the job. If you’re repairing a larger hole, consider using a self-adhesive patch or Hyde’s Wet ‘N Set, which eliminates the bedding coat and sets up quickly for fast repairs.
Paint
Changing the color of a ceiling can have a dramatic effect on a room’s overall look. Although it’s a high-up task, it can be relatively easy to complete with the right tools and methodical steps. It’s important to protect yourself while working on your ceiling. Put on some goggles and a mask, especially in older homes, where there is a chance that lead paint may still be present. You should also remove furniture or cover it with drop cloths to prevent dust and paint from damaging your belongings. Finally, make sure you turn off the electricity in the room if you plan to remove ceiling fixtures or fans.
Before you start working on the ceiling, clean it with a mild dish soap and water. Then, sand the surface to get rid of any imperfections. Once the sanding is done, you should wipe down the area and dry it with lint-free cloths. Now, it’s time to apply patching compound, using your putty knife to spread a thin layer over the damaged area. Once that has dried overnight, you can sand it again to blend the patched area with the rest of the ceiling.
Once the patched areas have dried, you can prime them with an oil-based primer. Then, you can begin painting the ceiling. Be sure to use a high-quality acrylic paint that’s specifically made for plaster surfaces. It’s also a good idea to apply multiple coats of paint, allowing each one to dry fully before applying the next.
If you’re repainting a whole room, it’s recommended to use a wide roller. This will help you cover the entire surface more efficiently and ensure a smooth finish. If you’re worried about the quality of your paint, ask your local home improvement store for recommendations.
Fixing peeling paint on a ceiling can seem like a daunting task, but with the proper preparation and careful steps, it’s an achievable project for most homeowners. Whether you’re fixing a crack, or repairing the line where the wall meets the ceiling, taking the time to thoroughly repair your work will result in a beautiful, blemish-free finish.
