I want to know the answer to the following question:
What term is used to describe what knots can do to affect the finish of things made from wood even when they've been painted?
All the background I'm provided with is that "A knot primer paint or solution, correctly applied during preparation, may do much to reduce this problem but it is difficult to control completely, especially when using mass-produced kiln-dried timber stocks.". Is that enough to answer the question?
Answer: no
