2. Apply a desiccant. A desiccant is a substance that absorbs moisture. You can purchase a desiccant at most hardware stores. Sprinkle the desiccant over the sealant and let it sit for a few minutes. The desiccant will absorb the moisture from the sealant and help it to dry faster.
3. Use a heat gun. A heat gun can also be used to dry sealant faster. Hold the heat gun about 6 inches away from the sealant and move it back and forth. Be careful not to hold the heat gun too close to the sealant, as this could damage it.
4. Let the sealant dry completely. Once you have applied a desiccant or used a heat gun, let the sealant dry completely before moving on. The drying time will vary depending on the type of sealant and the thickness of the application.
