If you’ve got holes or cracks in your wall, it’s time to spackle. Before you start your patching project, you’ll probably want to know, “How long does it take for spackle to dry?” Spackle is used by DIYers, handymen, and contractors alike to repair holes and dents in the wall. But making sure it’s dry before you sand and paint is essential. If you need general contracting work at your home or office, we serve the entire Sacramento area, including Auburn and Folsom, with home remodeling and general contracting.
In this guide, we’ll cover all the factors that affect how long it takes spackle to dry. Plus, we’ll walk you through how to spackle so you can get the best results.
Should You Paint Before Or After Flooring?
Factors that Affect Drying Time
How long does it take for spackle to dry? On average, spackle takes 1 to 2 hours to dry and 24 hours to fully cure. However, the actual dry time depends. Some spackles are formulated to dry quickly within minutes and are ready to sand within an hour or two, while others take longer.
In addition to the type of spackle, environmental factors affect the drying time. If the temperature is extremely low, the drying time will be a lot longer. Humidity can also slow down drying time. It’s best to apply spackle when the temperature is between 50 and 90 degrees Fahrenheit with low humidity.
Finally, the amount of spackle you use is going to have an effect on the time to dry. If you’re applying a large amount on a big hole, it’s going to take much longer than if you’re filling in a small hole.
Lightweight vs Heavyweight Spackle
Spackle comes in a variety of formulations, each of which can affect how long it takes spackle to dry. Lightweight spackle is made to dry quickly. It’s usually made of a binder like acrylic or vinyl and a filler like perlite. Lightweight spackle is best for small holes or dents. It goes on smoothly, especially if it has an added adhesive like sodium silicate, and can be ready to sand in an hour or two. However, lightweight spackle is less durable than heavier formulations and doesn’t sand down very well. It’s best for indoor repairs and small areas.
Heavyweight spackle, on the other hand, is made to be much more durable. It takes longer to dry–between 1 to 5 hours–and you typically need to wait 24 hours before sanding. Heavyweight spackle can be used on larger areas and can be sanded down easily. It comes in a few different formulations, including:
- Standard spackle: Made from gypsum, standard spackle can be used to fill holes larger than an inch. It dries harder than lightweight spackle, which makes it more durable.
- Vinyl: Vinyl spackle is made of limestone powder, vinyl acrylic copolymer, and elastic polymers. It’s bulkier than lightweight spackle, while also being flexible. Vinyl spackle is applied in layers, which allows you to fill in deeper holes. It works well both indoors and outdoors.
- Epoxy: Epoxy spackle is very durable, but it can be harder to work with. It doesn’t come premixed, meaning you have to combine the epoxy resin and the hardener before you can apply it. However, it’s water-resistant and long-lasting, which makes it a great choice for outdoor repairs.
Joint Compound vs Spackle
Both joint compound and spackle are similar materials that can be used to fix dents and dings in your drywall. The right one to use depends on the size of the hole you need to repair. Spackle usually dries faster, within 1 to 2 hours, while joint compound can take 24 hours before it’s fully dry and ready to sand and paint. Generally, spackle is used for small to medium repairs, while joint compound can be used to cover larger areas.
What Is Spackle?
Spackle is a putty-like substance usually made from a mix of gypsum powder and a binding agent that forms a paste. Spackle comes premixed and is used to fill small holes, cracks, and dents in drywall. Its consistency is similar to that of toothpaste, making it thicker and harder to spread than joint compound. However, the binding agent does provide elasticity, which means spackle is less prone to shrinkage and cracking.
What Is Joint Compound?
Joint compound is typically made with a mix of gypsum and limestone–the same as drywall mud–with other materials like clay, mica, perlite, and starch. It has a thick consistency similar to mud that is easy to spread. Although it can be used to fix small holes and dents, it’s more commonly used for seaming and smoothing drywall to create an even surface. It comes in large containers, rather than the small ones spackle comes in, and is designed for use on large areas.
Do You Caulk Before Or After Painting?
How to Spackle a Hole
While you may want to hire a professional to fix larger damage, you can easily fix small dents and holes in your wall. The key to a smooth finish is proper preparation and technique.
Tools needed:
- Putty knife
- Utility knife
- Fine grit sandpaper (220)
- Spackle
- Pick your compound. The size of the hole and its location will affect which one is right for the project.
- Clean the surface. Scrape away loose or chipped paint. Use a utility knife if you need to slice away drywall paper. Sand down rough edges.
- Stir the spackle. You can skip this if the container is fresh, but older spackle should be stirred once or twice.
- Scoop spackle onto the putty knife and swipe it across the hole at a 45-degree angle. Dipping the putty knife into water first creates a smoother finish.
- Smooth it out with the putty knife by swiping it once or twice. Scrape excess spackle back into the container.
- Wash the putty knife to get the spackle off before it dries using warm water and paper towels.
- Wipe any excess putty from around the hole.
- Wait for the spackle to dry. If the hole is more than ¼ inch deep, apply another layer. Once it’s fully cured, you can sand the spackle down so that it’s flush with the rest of the wall. Clean off any dust from sanding.
- Once you’re satisfied with the result, you can paint over the repair.
How to Speed up the Dry Time
So how long does it take for spackle to dry? Anywhere from a few minutes to hours, depending on the type of spackle and the size of the job. If you can’t wait that long to finish your repair job, there are some things you can do to speed up the dry time, including:
- Dehumidifier: You can use a dehumidifier to reduce the humidity in the room. It removes moisture and helps the spackle dry quicker. However, this won’t work on outdoor repairs.
- Air conditioner: Using an air conditioner is another option if you need the spackle to dry faster. Because cold air holds less water vapor, an air conditioner helps remove moisture from the air and speeds up drying time.
- Fan: You can use a fan both indoors and outdoors to circulate the air so that the spackle dries faster.
- Hair dryer: If you’re trying to speed up the drying on a small hole, you can use a hair dryer on the cool air setting.
