Apply Stain-Blocking Primer

What happens here

Before applying milk paint, it is crucial to address any areas of the furniture where the wood has been sanded down to bare wood or where natural wood tannins are visible, as these can bleed through subsequent paint layers. The presenter demonstrates using Zinsser B-I-N Shellac-Base Primer in an aerosol can. This type of primer is highly effective as an 'ultimate stain blocker' because it seals in knots and tannins, preventing discoloration. Carefully spray a light, even coat of primer over the identified problematic spots, such as the furniture's legs and table top, ensuring full coverage on these areas. This ensures a clean, consistent, and stain-free foundation for the milk paint, contributing to a professional and lasting finish. The primer is known for its quick drying time, typically within 15 minutes.

Goal: Apply a shellac-based primer to specific areas of the furniture that have exposed bare wood or visible tannin bleed to block stains and prepare the surface for milk paint.
