You can tint the latex a vivid colour or leave it with a natural look. The process is relatively fast, allowing you to create many latex sheets in a short time.

Clean a large counter top or workbench with multi-purpose cleaner to prepare it to make the latex sheet. Allow the counter to completely dry.

Add a latex tint to liquid latex, following the instructions on the bottle, if you want a coloured sheet. Untinted latex is a yellowish colour when it dries.

Pour a small amount of liquid latex on to the counter and use a foam brush to spread it out to the dimensions that you require. Add more latex if needed until you have covered the entire area.

Dry the latex with a hair dryer.

Apply at least three more layers of latex, using a new foam brush for each layer. You can add as many layers as you wish until you reach the desired thickness. Thicker sheets are stronger, but they do not stretch as well as thin sheets.

Apply baby powder to the surface of the dried sheet. This will prevent the latex from sticking it itself.

Peel the sheet off of the counter slowly, brushing powder underneath it as you go.

Trim the edges of the sheet with a sharp pair of scissors if needed.
