Epoxy grout is known for its durability and resistance to stains and water damage, making it an excellent choice for areas exposed to moisture. Unlike traditional cement-based grout, epoxy grout doesn't crack or shrink over time, which is why some might consider skipping caulking when using it. However, despite these properties, caulking is still essential in certain areas. For instance, any change of plane in the tiling work—such as corners, edges, or where the tile meets another surface—should be caulked. This is because these areas are prone to movement and expansion, which can lead to cracking. Caulk is designed to be flexible and can absorb this movement, preventing damage. Therefore, even with the use of epoxy grout, caulking is necessary for ensuring the longevity and integrity of your tile work in specific areas.

Carpet beetles, known for their diet based on animal products like wool, silk, feathers, and leather, do not typically consume synthetic materials such as polypropylene. These synthetic fibers lack the natural proteins that carpet beetles seek in their diet. However, it's important to note that while they may not eat polypropylene, carpet beetles might still inhabit areas with synthetic carpets if there are other sources of food available, such as spilled food, pet hair, or natural fibers mixed into the synthetic carpet. To prevent an infestation, regular vacuuming and prompt cleaning of spills are recommended, even on synthetic carpets.

Yes, inkjet printer ink can dry out. This typically occurs when a printer is not used frequently, allowing the ink inside the cartridge or the print nozzle to dry and clog. The drying process happens because the ink used in inkjet printers is water-based, and when the water evaporates, it leaves behind the pigments and other components of the ink. This can lead to poor print quality or even prevent printing altogether. To minimize the risk of the ink drying out, it's advisable to use the printer regularly and perform maintenance tasks such as cleaning the print heads. For those who use their printers infrequently, considering a laser printer might be a better option, as toner does not dry out like inkjet ink.
