Unless otherwise stated, most of my acrylic paintings are done on quality canvas that has been affixed to hardboard. They can be framed, matted & framed or simply displayed on easels. Here are some guidelines as to the handling of acrylic art:
Minimize the handling of the artwork to avoid damage. Larger pieces may need to be supported from the back, whether they are framed or not. Secure the painting in place with acid-free framing tape; white artist's tape works well for this purpose. Double-sided tape works well for securing an unframed painting to the backing.
Keep the acrylic painting out of direct sunlight or strong artificial light, as these will cause the paint to fade. Also avoid any environment that is hot or that has excessive moisture; these will harm the integrity of the paint.
Frame the acrylic art piece to block dirt and dust from gathering on the paint. Do not let the painting touch the glass; acrylic paint can be damaged by glass. Scrap strips of cardboard or mat board can be used as spacers between the painting and the glass, or simply skip the glass altogether.
