Diagnosing the Problem. If leaves on an aloe plant develop dark spots, it's critical to diagnose and correct the problem quickly. The most likely cause is too much water, which promotes growth of fungal microorganisms that cause spotting of leaves.
If you're painting Plexiglas, not just any paint will do. Some paint may not adhere well, if at all. Acrylic paints work best on Plexiglas, and spray paints designed for plastic work as well. Clean the Plexiglas with water and a mild soap such as liquid dish soap, rinsing it off thoroughly afterwards. If your goal is for the paint to adhere well, scuff it up with a fine-grit sandpaper; paint doesn't adhere well to slick surfaces, so the sanding gives the paint something to grip.
About Acrylic Sheeting. Acrylic sheets, also referred to as âplexiglassâ or âPlexiglasâ, are often used as an alternative to glass sheeting. Plexiglass sheets offer similar transparency to glass, but they are more durable and relatively shatter-proof. Acrylic sheeting can be used to replace window panes, protect surfaces or even hold items as shelving. Since plexiglass is typically sold in predetermined sizes, consider everything you can use this material for and then purchase the amount you need. You can always have the sheets cut to size.
