Acrylic Sheets can be displayed as self-supporting paintings, collages or sculptures and can be made with a variety of acrylic mediums. You can use a combination of mediums based on the results you want to achieve. Different mediums will produce varying characteristics for your finished product. The sheets can be created in various degrees of flexibility, sizes, textures, colors, sheens and thickness to create beautiful pieces of artwork, such as wall paintings, quilts and canvases.
Select a smooth piece of glass or plexiglass larger than the acrylic sheet you will be making. Use masking tape on the glass to tape out the desired size and shape of the acrylic sheet.
Apply the desired amount of acrylic fluid medium inside the tape using a one-half to two-inch soft artist brush. You can use a thinner to thin the mixture to create minimal brush marks. Allow the coating to fully dry.
Repeat the steps until you can peel the coating from the glass without tearing it. Apply coats based on the desired thickness. Coat layers in different directions, starting with horizontal strokes and moving into vertical strokes. Continue this layering process until you achieve the level of thickness that produces the desired effect.
Apply fluid medium with a medium nap roller in order to apply the thinnest application of acrylic. There may be some air bubbles in the finished sheet.
Apply a 1/8-inch to 1/4-inch application of a gel medium using a 2-inch to 6-inch trowel. On a smooth sheet of glass, use masking tape to tape desired shape in four to five successive layers. This will build up a ridge around the image. Use a carpenter's level to insure the surface is level.
Pour the fluid medium over the surface. If needed, spread it around with a soft brush while the mixture is still wet. Allow 48 to 72 hours to completely dry. Use a razor blade to score along the taped edges to separate the sheet from the tape, and peel. You can also dampen the surface with a wet sponge to release the acrylic sheet.
