How to paint over glossy walls without sanding

Hi! What’s the best way to prep and paint over glossy or semi-gloss walls without having to sand everything?

Hi! Painting over glossy or semi-gloss walls without sanding is totally doable with the right prep. Start by giving the walls a good cleaning since glossy surfaces tend to collect grease and dust, which can mess with paint adhesion. After that, a liquid deglosser can really help. It’s easy to apply and takes the shine off so the new paint has something to grip. Once that’s dry, follow up with a quality bonding primer. That extra layer goes a long way in making sure your paint sticks well and holds up over time. It’s a simple process and a lot less messy than sanding everything down.

Thanks! Will a liquid deglosser still work effectively on semi-gloss kitchen walls if there's some grease buildup?
