Solution

Do not paint when the wall has too high humidity. Make sure your surface is dry and free of moisture before painting. Allow enough time to dry before repainting. If the blisters are above the surface, moisture is an issue. In this case, ONIP recommends installing vents and exhaust fans in the affected areas. Choosing the right Onip Aqua 50 Imprim primer for the type of surface is your best solution that can be the difference between success and failure.
