If there are several drywall panels around a corner, cover each panel with mud before drying guns have time to cool down. In order for it to work, you need joint compound in your taping knife or roller and then apply it sparingly over the surface of one side of the tape line. Using a drying gunĪ drying gun is a device that helps speed up the drying process by directing electric heat to surfaces. Finally, once you’re done with the application, wash your mud pan to prevent residual hot mud from setting on it. Since you don’t want the hot mud drying up before applying it, mix just a bit of it on your mud pan as you go along. The downside to such an extremely fast curing time is that it doesn’t leave much room for error correction. This is a fast drying time given drywall mud can take up to 24 hours to dry. Hot drywall mud is a powder that’s mixed with water to form a joint compound that cures within 20-60 minutes. Painting partially frozen joints can lead to structural problems such as bulging drywall panels over time. Such forcefully blown air when coupled with low-temperature conditions can trigger freezing of the joint compound prior to curing. Take caution when using artificial or natural wind (opening windows) to create better ventilation for faster setting of drywall mud. The breeze generated by the fans will reduce the humidity levels. If you don’t have a dehumidifier, you can prep the room for mudding a few days prior by installing fans to improve the air circulation. The optimal relative humidity range for curing drywall mud is 20-40%. Since drywall mud has moisture, running a dehumidifier in the house for at least 10 hours will reduce the drying time significantly.
Note that by mixing the compound with less water and using latex primer or adhesive instead of joint compound on joints can help cut drying times down from over 30 hours for some types of mud to around 12 hours. Subsequent coats can then be thinned out if your goal is to dry the joint compound faster. The initial coat is usually required to be the thickest and should thus be allowed no less than 24 hours of drying time. Apply thin layers which allow for better ventilation, as well as quicker drying times. Lighter coats of joint compound dry faster than thicker applications. The good thing is, there are a few hacks you can try to make the mud cure faster. The type of compound can also determine how long it will take for it to be safe to apply the next coat. It can take quite a long time for your joint compound to cure especially if you’re applying several coats. Fortunately, there are a few ways you can shorten the drying time by up to half, as I’ve discussed in the next section. If you prefer a faster curing time, use setting compound instead of regular joint compound as it can dry as fast as 5 minutes after application depending on the type.Īvoid painting over wet drywall mud at all costs because that could increase the shrinkage of the joint compound. The curing time varies depending on the thickness of the joint compound, depth of application, humidity levels, and temperature. Always allow the mud to dry before applying a new coat.Īs a rule of thumb, allow e very coat of drywall mud to cure for at least 24 hours before sanding, painting, or appl ying the next coat. How long does drywall mud take to dry?Ī coat of drywall mud takes about 24 hours to dry when the temperature is about 70☏ and humidity at 70% or lower. Alternatively, use hot joint compound for your applications, apply thinner coats, or run a drying gun to reduce the curing time of your drywall compound. The best way to dry drywall mud faster is by running a dehumidifier in the room to reduce moisture in the atmosphere.
The slower you let your drywall mud air out, the better it will be at handling any bumps or scrapes that might happen in the future. Quick Set Lite Compound is used as a prefill material for gaps in gypsum board construction that are wider than recommended and also in voids in above-grade interior concrete.Is there a way you can increase the rate at which drywall mud cures during drywall finishing? Most people don’t realize that one of the most important aspects of drywall installation is letting the compound cure for 2-3 days or at least 24 hours.Quick Set Lite Compound is compatible with all types of gypsum board and may be used where a shortened joint finishing schedule is desired.Quick Set Lite Compound permits heavy fills and faster joint finishing with low shrinkage.Quick Set Lite Compound is specially formulated to provide excellent joint strength, even in poor drying conditions.Quick Set Lite Compound provides a lightweight, easy to sand finish for fast, smooth joint finishing.Available in 20, 45, 90 and 210 minute set times.
