Proper stain treatment is important step when preparing to paint interior surfaces. Before applying any paint, it’s essential to thoroughly clean the surface and treat any existing stains with special stain blocker to ensure optimal paint adhesion and prevent the stains from bleeding through the new paint.
For common household stains like grease, crayon, blutac, food or water stains begin by gently scraping off any excess material with a putty knife or similar tool. Next, apply a coat of high-quality, water-based or shellac blocking primer directly onto the stain, extending a few inches past its edges.
This primer acts as a sealing layer to lock in the stain and provide a stable surface for the paint to adhere to. Allow adequate drying time per the manufacturer’s instructions before painting over the primed area.
For more stubborn stains like permanent marker, lipstick, or water damage, you may need to apply multiple coats of a stain-blocking primer.
Properly treating any stains before painting is key to achieving professional-looking, long-lasting results on your interior surfaces.
