If your premixed drywall mud is dried out or has begun to set in the bucket, you may be able to revive it by adding warm water and stirring. However, the first and most important step is to scrape off any hard, dried bits of drywall that may have accumulated toward the top of the container and throw them away because they will not easily reconstitute back into the drywall mud mix.
While it is possible to repair minor plaster cracks or holes yourself, it is generally not recommended for larger jobs or if you want a professional result. Plaster repair can be difficult in practice; proper wall preparation and achieving a smooth, seamless finish that blends with the existing wall requires experience, especially on textured surfaces. Hiring a professional ensures the repair will be durable and last longer, potentially saving you money over time. A pro can also determine if the cracks are from normal expansion or a more serious underlying issue.
You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.
Whether you can install or repair plaster yourself depends on the project's size and your comfort level with DIY projects. It's possible to handle small repairs on your own, but for larger projects like a room restoration or a full installation, it's often best to hire a local plaster professional. The final appearance, even coverage, and durability of the plaster depend heavily on proper wall preparation and application. If you are not 100% confident in your ability to achieve a professional result, letting an expert handle the job is a worthwhile investment.
Plaster repair costs range from $4 to $10per square foot for refinishing, while skim coating can be less expensive, usually between $2 and $5 per square foot. The price you pay for plaster repairs will depend on the extent of the damage, the type of plaster you have on your walls, and the accessibility of the damage. Plaster repair on the exterior of your home tends to be more expensive, as there’s a higher chance that ladders or scaffolding will be necessary to carry out the repair.
