Zinsser Bulls Eye 1-2-3 is a water-based primer that is generally not recommended for covering wood knots, as it lacks the shellac base needed to stop the resin from bleeding through and causing yellow stains. Instead, for permanently blocking knots, you should use a shellac-based primer like Zinsser B-I-N.
HI, Zinsser 123 is a water-based sealant and will not stop the resin in the knots from bleeding through. Zinsser BIN primer is a coloured shellac-based sealant and IS suitable for using to seal knots.
Prime the knots
Apply Zinsser B-I-N® or B-I-N® AQUA directly to the knots. This primer is effective in sealing the resinous areas and preventing stains from bleeding through the paint.
For hiding knots, Zinsser hasd two solutions - B-I-N and B-I-N Aqua. B-I-N will be touch dry in 15 minutes and recoatable in 45 minutes, whereas B-I-N Aqua will be touch dry in 25 minutes and recoatable in 45 minutes. However, it's crucial to allow the full 2 hour drying time before applying additional coats.
Ronseal Knot Block Primer and Undercoat permanently blocks wood knots bleeding through the paint surface. It gives a flawless finish that won't yellow. This paint prepares bare and previously painted interior wood for top coat paints and covers bold colours, dark marks and helps paint to stick.
Apply primer generously over knots and surrounding areas. For wood with heavy knots, priming the entire surface is often the best approach for consistent results. Proper sealing outdoors protects wood from both weather and knot bleed.
The hiding of knots is something that primer should have been used for. More coats won't help. The resins in the knots will bleed through many coats over time. As time goes on more knots will show through and they will get darker.
Choose Zinsser BIN for tough stain-blocking, odors, and raw wood/MDF. Choose Zinsser Bulls Eye 1-2-3 for general interior/exterior adhesion, masonry, and painting over glossy surfaces.
SURFACE PREPARATION
