Should you wait for your watercolor painting to dry before sealing it?
One of the most common questions artists ask when it comes to sealing a watercolor painting is whether they should wait for the painting to dry before applying the sealant. The answer is yes; you should always wait for your watercolor painting to dry completely before applying any type of sealant.
When you apply a sealant onto a wet or damp surface, it can cause the colors to bleed or shift. Additionally, it can also trap moisture between the paper and the sealant, which can lead to mold or mildew growth over time.
Waiting for your painting to dry completely will ensure that the colors are set in place and that there is no moisture trapped beneath the surface.
How long should you wait?
The drying time for watercolor paintings varies depending on several factors such as humidity levels and paper thickness. As a general rule of thumb, it is recommended that you wait at least 24 hours before applying any type of sealant. However, if you’re unsure whether your painting has dried completely or not, you can use a touch test.
To perform a touch test, gently touch an inconspicuous area of your painting with your finger. If there is no transfer of color or moisture onto your finger, then the painting is dry and ready for sealing.
Different types of sealants for watercolor paintings
There are several different types of sealants available for use on watercolor paintings. Each type has its own unique properties and benefits, so it’s important to choose the right one for your painting.
Solvent-Based Sealants
