Hi fellows, I'd shifted in for a few months. While shifting furniture around &/or installing other small furnishings, I caused some damages to my walls & ceilings paint job. My ID kept some of my leftover paint around. May I know: Qn1: if it is possible to use a water-colour brush (yes, those small-tipped ones used for art & craft) to directly paint over these areas?: (Exhibit A): around 10-cent coin diameter (Exhibit B): half a palm size Cause from what I see on YouTube most of them tutorials sand off a lot of the area surrounding the damaged spot, then paint a base white, then paint a few more coats of the desired colour paint. But as you can see in my exhibit, my "damaged areas" so small only... Qn2: may I know how to determine if my leftover paint is in a ready-to-use mix, or need to mix with some other chemicals before using?
