While painting can certainly change the look of a chimney, you should think twice about giving your brick chimney the old landlord special.

Painting brick is porous, meaning it’s full of tiny holes that can soak up moisture. Those holes also allow it to dry, though. So, when you paint it, you trap any moisture inside, providing an opportunity for mold, mildew, and water damage.

Paint also shows wear faster than naked brick. This means that once you paint a brick surface, you’ll have to keep painting it to maintain a clean look. A paint job is also harder to undo on brick because of its porous nature. Once you paint it, it’s hard to go back without some serious power washing—another added cost.

It is possible, albeit a lot slower, to break up a rock using water. You would do this by freezing and thawing the water. You could create some initial holes or cracks in the rock, then pour water into the cracks or holes and allow them to freeze (so it's best to do this in winter or in colder climates). Since water expands when it freezes, this puts pressure on the inside of the rock and causes it to crack. You could continue to pour more water in and let it freeze to continue to break up the rock.

Mortar, or masonry mortar, is mainly used in joints and as parging for stone, brick, or cement construction. Stucco is primarily a surface material used as wall coverings. For maintenance, masonry will need repointing or replacing as damage or land shifting occurs, whereas stucco will need patching or refinishing as it tends to crack over time along with other types of wear-and-tear.

Most of the time, you don’t need to seal brickwork and can save that money for another area of home improvement. But if your brick is cracking or you live in an area with a lot of excess moisture (either in terms of rain or freezes), sealing can extend the lifetime of your home. But, make sure you use a breathable sealant, like siloxane, to allow the moisture to evaporate on its own.
