Hello, I have an interior exposed brick wall that has some good parts but others that have very rough joints and uneven brick work due to various path jobs over time. Right now it has whote primer but it is clear that a coat of paint isnt goint to be nearly enough to make it look uniform. i consodered lime slurry bur it has a rough, sandy type finish that isnt ideal. what would be ideal is something that smoothes over the rough spots and has a smooth finsih too. Any ideas would be very welcome!,
