What happens here

After masking, prepare the trim surfaces. Inspect the trim for any nicks, dings, or imperfections. Use a 3M sanding sponge to lightly sand these areas until smooth. Once sanded, apply a liquid de-glosser like Krud Kutter Gloss-Off to all surfaces that will be painted. This product cleans and de-glosses without requiring additional sanding or rinsing, ensuring excellent adhesion for the new paint.
