Hey, I recently saw knots developing through the paint I applied to my wooden door. So, I wanted to take immediate action and understand how to stop knots bleeding through paint. Fortunately, I found a good method. You have to use shellac or a stain-blocking primer for this purpose. I’ve shared the steps in detail to help you with your query.

How to Stop Knots From Bleeding Through Paint?
Here is the process:
Prepare the surface first. This includes making space and covering the floor with drop cloths. If the surface you’re fixing is quite big, move the furniture out as well.
Use 120-grit sandpaper and sand the knots. This will help roughen and even out the surface, making it easier for the latter process. Sand the entire knots in a circular motion. Every area that will be painted must be covered.
Take a stain-blocking primer or shellacs which are made to block knots. The primer should be a white one.
Dip your foam brush into the primer and paint a thin layer over the knots.
Don’t apply excess stain blocker on one part or it will create lumps.
Wait for about 30 to 45 minutes for the primer to dry completely before moving ahead.
A simple touch test will tell you whether you need to give the primer some more time.
After the first coat dries, sand the knots again.
You can apply another coat if said by the manufacturer’s guidelines. Wait for the second coat to dry, too.
Again, use your 120-grit sandpaper to sand the knot surface lightly in the process of how to stop knots bleeding through paint.
Paint the surface with a roller or brush. If you’re painting just over the knots, ensure it matches the colour of the rest of the surface.
Apply another coat of paint after the first one dries completely. Paint slowly and evenly.
This is all about how to prevent knots from bleeding through paint. I hope it helps.
