Yes, it's generally advisable to apply a primer before painting, even if you've used damp sealant on your walls. Primer helps improve paint adhesion, provides a more uniform surface for painting, and can enhance the durability and longevity of the paint job. If you've used a damp sealant, the primer will create a better surface for the paint to adhere to, ensuring a smoother and more even finish. Additionally, primer can help to block any remaining stains or discoloration, promoting a more professional and aesthetically pleasing result. Choose a primer that is suitable for the type of surface you are painting and compatible with the paint you plan to use. Always follow the manufacturer's instructions on the primer and paint products for the best results.
