You do not normally need to sand it, unless it's quite rough.
The paint finish doesn't significantly change the surface preparation necessary. If the paint is the same type (water based going over waterbased or enamel over enamel) then the preparation is simply: * cleaning, * remove loose material, * fill any holes or hollows, * sanding and * wiping, If you are changing the type of paint (eg: painting waterbased over enamel) you may need to use an etch primer to "key" the surface and give the new paint a texture to grip onto after sanding, and otherwise prepare as above.
A fine sanding or the use of a de-glosser will give the primer tooth.
Perfect surface preparation and spray application.
I don't believe there is 'water based enamel' -that's a contradiction. Answer If your previous paint is glossy, trying washing it with TSP (or substitute) and lightly sanding it. Try the latex to see if it will adhere without bubbles. Give it plenty of drying time.
Before you start painting, the surface must be smooth. Start off with a universal undercoat and sand lightly when the undercoat is done. Dust off the piece to be painted, ensuring no dust left from sanding is on the surface. The finish is in the brush, and a little patients with smooth strokes. If it is a big flat surface get a sponge roller, and apply a few light coats with drying in between, instead of trying to just paint one thick coat, a common mistake. In between every coat of enamel, use a fine grit (200-300) to sand out any imperfections and paint again. Repeat until satisfied with the finish.

Well, honey, technically you can spray enamel paint over acrylic paint on a car, but it's not the ideal scenario. The two have different properties, so the enamel might not adhere properly and could lead to chipping or peeling. If you want a paint job that lasts, I'd recommend sanding down the acrylic paint before applying the enamel.
Of course you CAN, but they will separate before you begin to apply them if it's a really fast setting enamel. The acrylic will run down over the enamel.
To remove black enamel paint from clothes, first scrape off excess paint with a blunt tool. Then, apply a pre-treatment stain remover or liquid detergent directly to the stain. Next, launder the garment using the hottest water temperature recommended for the fabric. Repeat if necessary before drying.
Enamel RTU powder, as an important innovative product in the enamel industry, has been widely applied in various fields in recent years. It is produced by precise ball milling of enamel frits and additives, possessing a series of unique performance characteristics and significant advantages. 1.Performance Characteristics of Enamel RTU Powder 1.1 Composition and Preparation: Enamel RTU powder is a powdered enamel frit material made from special enamel glaze materials or a specific ratio of enamel glaze, clay, and additives. Enamel manufacturers only need to mix the RTU powder with water to easily prepare enamel slurry for wet coating applications. For slurries with specific fineness requirements, they can also be slightly ground in a ball mill. 1.2 Easy Storage and Use: Enamel RTU powder exists in powder form, making it convenient for storage and transportation. When in use, it only requires mixing with water, eliminating the need for complex equipment or enamel processing procedures. 2.Advantages 2.1 Energy Saving and Environmental Protection: The use of enamel RTU powder reduces the demand for ball milling equipment. The preparation process for the RTU powder is relatively simple, which decreases the workload associated with material preparation and equipment maintenance. 2.2 Increased Efficiency and Reduced Costs: The use of enamel RTU powder simplifies the preparation process for enamel slurry, saving time and labor costs. It allows for precise control of the quantity of enamel raw materials, avoiding waste and lowering production costs. 2.3 Ease of Customization and Optimization: The R&D team at Nolifrit can tailor premixed powder formulations according to different production conditions and customer needs. By optimizing these formulations, the quality and performance of enamel products can be enhanced, meeting the diverse requirements of enamel factories. 2.4 Wide Application: Enamel RTU powder has been widely applied in various fields, including cookware, single-coat enamel products, and GGH enamel heat exchange components. It is suitable not only for traditional enamel product manufacturing but also for emerging fields that demand higher quality standards for enamel. 2.5 Professional Technical Support: Nolifrit possesses specialized enamel technology and knowledge. Enamel manufacturers can receive reliable technical support and services, ensuring that the quality and performance of their products meet expected standards.
To effectively repair tub enamel damage, you can use a enamel repair kit that can be purchased at a hardware store. Follow the instructions carefully to clean and prepare the damaged area before applying the enamel repair solution. Allow it to dry completely before using the tub again.
To effectively repair a cast iron tub, you can start by cleaning the surface thoroughly and removing any rust or chipped enamel. Next, use a high-quality epoxy or enamel repair kit specifically designed for cast iron surfaces to fill in any cracks or chips. Allow the repair to dry completely before sanding it down to ensure a smooth finish. Finally, apply a new coat of enamel or paint to match the original color of the tub.
The shimmer effect in pearlized enamel is typically achieved by adding mica or other similar reflective pigments to the enamel formulation. These pigments reflect light and create a shimmery or pearlescent appearance in the enamel when applied and dried.
