A: Painting directly over knots without using a primer is not recommended, as this increases the likelihood of knots bleeding through the paint.Water, mold, and rust stains are tough to cover, but odors are even harder to conceal.

Always follow manufacturer recommendations and best practices to ensure the longevity and quality of your finished work.

Building from Scratch A: This is a very common issue and you can see a typical example of it in the photo above. In this case the staining even came through heavy coats of oil-based paint.

Pros are getting an oil-like appearance with Ben Moore’s Advance and we explain why in this post, and how to apply it in the post on painting over stained trim.Issue: Environmental factors, such as high humidity or temperature, are affecting the drying process, causing the paint to blister or peel around the knots.
