Will tacky paint ever dry?
You can experience the consequences of tacky paint for several days, weeks, months, and even years. If there’s a lot of humidity or it’s too hot, then your paint will take longer to dry.

Is enamel paint more durable?
Enamel can last longer and it’s more resistant to cracks and does not fade, unlike acrylic paint. Enamel is not the best choice for outdoors because it’s less flexible than the acrylic and becomes harder which can lead to cracking.
