Yes, many artists choose to ink before applying watercolor for a couple of key reasons. Firstly, inking before adding watercolor ensures that the lines remain crisp and visible after the paint is applied, which is especially important if you're aiming for detailed or illustrative work where precision is crucial. Secondly, most inks are waterproof once dry, preventing them from bleeding or smudging when the watercolor is applied. However, it's essential to make sure the ink is completely dry before proceeding with watercolor to avoid any unwanted mix. Additionally, this approach allows for better control over the final look of the artwork, as it's easier to maintain clean lines and details that can sometimes get lost under layers of paint. That said, the choice between inking before or after watercolor largely depends on the artist’s preference and the desired effect of the artwork.

To spray cellulose insulation, first, ensure safety by wearing protective gear such as a mask, goggles, and gloves. Rent or purchase a cellulose blower machine, which is typically available at home improvement stores. Prepare the area by sealing off any openings or fixtures with tape or plastic coverings to avoid accidental coverage. Load the cellulose material into the machine hopper. Begin applying the cellulose by starting from the farthest corner of the space, working your way towards the entrance to ensure even coverage. The machine should be set to the manufacturer's recommended settings for the type of application you're performing (e.g., attic, wall cavity). Maintain a consistent movement and distance from the surface being insulated to prevent clumping or uneven distribution. It's crucial to fill the space adequately but avoid overpacking, as cellulose needs space to expand and settle. Clean up any overspray or spills immediately to prevent a more challenging clean-up later.

Generally, inkjet pictures are not waterproof due to the water-soluble inks used in most inkjet printers. These inks can smear, blur, or wash away upon contact with water. However, waterproofing can be achieved through special means such as using waterproof inkjet papers, which have a protective coating that repels water, or by applying a clear, waterproof sealant spray over the printed photograph. These solutions can significantly enhance the durability of inkjet prints against water damage. Additionally, some inkjet printers use pigment-based inks, which are more water-resistant than dye-based inks, offering better protection against moisture.
