Hi all! What’s the difference between a stain-blocking primer and a bonding primer, and in what situations does each one work best? Thank you in advance!

Hi there!
Stain-blocking primers and bonding primers serve different purposes, and knowing when to use each one can really improve your results.
Stain-blocking primers are meant to seal in and stop stains from showing through the topcoat. They work best on surfaces with water stains, smoke damage, grease, crayon marks, or tannin bleed from certain woods like cedar or redwood. These primers are a must if you're painting over areas with visible discoloration or anything that might bleed through the paint.
Bonding primers are used to help paint stick to hard-to-paint surfaces. These include glossy finishes, tile, vinyl, laminate, or metal. They create a surface that allows paint to adhere properly, which reduces the chances of peeling later on.
So, in short:- Stain-blocking primer is for covering up stains and preventing them from coming through.
- Bonding primer is for making sure the paint sticks to smooth or slick surfaces.
Sometimes you might need both, depending on the situation.
Hope this helps!
