My brass bathroom basin is old and discolored, but the cabinet is in great shape . can i paint the interior of the basin
Yes, but you may not like it. Assuming this bowl is solid brass, you have 3 options. 1. To make it appear fabulous you can shine up the whole thing with steel wool to remove the entire original finish. Work through steel wool grades from medium to very fine and then using brass polish. This will make it look great, but you will have to repeat this every month or so because it will repeatedly tarnish. 2. After cleaning it up the first time you can use a spray lacquer to seal it. (Mask off the surrounding stuff!) This will not be nearly as durable as the original clear finish, but it will remain nice much longer than using no finish, and it will make it harder to polish up again next time. 3. You can remove the bowl and have it professionally refinished. This is expensive but will give you durability somewhere between option 2 and the original finish. My suggestion is to first confirm that it is solid brass. Try a magnet first, it it sticks you have brass plated steel which will show through if you try to polish it up. Even if the magnet does not stick, try making a deep scratch on the underside of the bowl and looking for telltale silver color of aluminum or zinc. If it's solid brass, go with option 1. If it requires re-shining more often than you would like, then go to option 2.
If it is not solid brass, then you can paint it, but it won't look good or last very long.
Good luck. Read More At : Smooth Oval Undermount Bathroom Basin in Polished Brass...
