Every picture framer has their own way of framing paintings. I use the following technique on both oils and acrylics:

  • To prevent the painting edge from deteriorating because of the acids naturally found in wood frames, I seal the sides of the rabbet with Aluminum Barrier Tape. The blue paper that comes in contact with the edges of the stretched painting is acid free.
  • To protect the surface of the painting that rests on the rabbet of the frame from the same acids, I add a Foam Rabbet Tape to the face of the rabbet. This is an inert polyethylene foam that is acid free and acts as a barrier between the acid that is in the wood of the rabbet and the painting itself. Over a period of time, the edge of the painting that wraps around the stretcher bars that comes into direct contact with the rabbet of the frame becomes very fragile.
  • I always use Offset Clips to secure paintings into frames. I NEVER “toe nail” through the stretcher bars into the frame.  The stretcher bars on frames need to move ever so slightly in reaction to the movement of the paintings. Yes, paintings “move” according to their environments.
  • Bump-ons are added on the bottom corners to both keep the painting straight on the walls and to allow air to flow around the paintings.
  • Foam Core or Tyvec paper are added to the back to prevent damage from occurring to the back of the painting and to deter little critters from moving in.
