Yes, fiberglass tissue can be painted or coated. Fiberglass tissue is a thin, non-woven fabric made from glass fibers. It is often used as a reinforcing material in composite structures, such as fiberglass-reinforced plastics (FRP) or fiberglass-reinforced concrete (FRC).

When using fiberglass tissue in applications where it will be painted or coated, it's important to prepare the surface properly to ensure good adhesion of the paint or coating. This typically involves cleaning the surface to remove any dust, dirt, or contaminants, and possibly roughening the surface slightly to improve adhesion.

Once the surface is prepared, you can paint or coat the fiberglass tissue just like you would any other surface. However, keep in mind that because fiberglass tissue is a porous material, it may require multiple coats of paint or coating to achieve the desired coverage and finish. Additionally, you may need to use a primer specifically designed for use with fiberglass surfaces to ensure proper adhesion of the paint or coating.
