Water mold is when something has been saturated in the water for some time and was never dried off. Water stain means something was saturated but then cleaned off to prevent mold from growing.
A mold is a form into which molten metal is poured. When the metal hardens, it takes the shape of the mold. This process is called casting.
To make a mold for metal casting, you can use a material like sand or plaster to create a negative impression of the object you want to cast. Once the mold is made, you can pour molten metal into it and let it cool and solidify. After that, you can remove the mold to reveal the metal casting.
To stain metal effectively, start by cleaning the surface thoroughly to remove any dirt or grease. Next, apply a metal primer to help the stain adhere better. Then, use a metal stain or patina solution to achieve the desired color or finish. Allow the stain to dry completely before applying a clear sealant to protect the finish.

I would suggest hydrogen peroxide. Spray it on with a trigger sprayer and brush the stain, then rinse with hose or absorb with cleaning towels. Mold can leave a permanent stain, but the peroxide serves as an anti-bacterial agent that should kill the mold, preventing the spread of it.
Sand mold is commonly used in metal casting as it can withstand high temperatures and is easily moldable. The process involves creating a cavity in the sand mold that matches the desired shape of the metal casting. Molten metal is then poured into the cavity and allowed to cool and solidify, resulting in a metal casting that replicates the mold's shape. Sand mold is cost-effective and versatile, making it a popular choice in the metal casting industry.
Yes if there is mold growth on the concrete from the moisture.
To create DIY metal casting molds at home, you can use materials like sand, clay, or plaster to make a mold of the object you want to cast. Once the mold is ready, you can melt metal in a furnace or with a torch and pour it into the mold. Allow the metal to cool and solidify before removing it from the mold.
To effectively remove a mold stain from a surface, you can use a mixture of water and detergent, or a solution of vinegar and water. Scrub the affected area with a brush or sponge, then rinse and dry thoroughly. For tougher stains, you can use a commercial mold remover following the instructions on the product label.
Molten metal is poured into a mold cavity through a sprue, which is a channel that allows the metal to flow evenly. The temperature of the metal is crucial to ensure proper flow and fill of the mold. After pouring, the metal solidifies and takes the shape of the mold, creating the desired metal part.
