Conservation Framing: 12 – The Back of the Frame

October 4, 2019

This is the video number 12 of the course
of conservation framing carried out by Rinaldin. The course is edited and presented by Mal
Reynolds who is a recognized authority in this field. In order just to finish the back off what
we need to do is we need to have a good strong backboard. This is Corricor and this works perfectly
well in the conservation process. It is strong, it is hard and its purpose is
to actually stop damage coming in from the back of the artwork itself. So I would place the actual board in the frame
itself and I would put pins probably between 100 and 150 mm apart to hold the board in place. As I said, in this case we’re using Corricor.
You can use conservation board. There are several on the market, but framers
should avoid using grey board or any poor quality boards because remember we’re talking
about conservation processes and in some cases the majority of the deteriorating agents will
come from the back board and from poor back board itself. Once we have all the frame parts or any of
the actual frame itself we need to secure the back and I do so by using the pins. These are steel pins and they’re rigid. Semi-rigid or flexible pins will not good
for conservation work because they could bend and so, what I’m going to do, is put the rigid
pins in and I use them at about between 100 and 150 mm apart. As a clue this wedge part, at the back the
actual pin gun itself, if I put that up to the edge of the moulding, like so, so that is a good place to start with the first pin at this edge And then I will take in this case one in the
middle and that’s how I would actually locate the pins remembering that these are rigid
pins and they actually come like that. What I’m doing now is I’m going to seal the
the back of the frame to prevent any dust or debris getting into the back. So I cut 4 strips of brown gummed tape to
the suitable length. I’m now going to moisten those with my sponge
and water. I lay it across the back of the frame onto
the edges and then, taking my cloth, I just fasten that down (make sure the adhesive has
taken) and then I cut down the edge here and then gradually put it down into the corner and tape over. I make sure it is all sealed at these sides
and take the ruler and trim off the excess. If, for instance, you end up with a piece
getting a bit like that, then I just re-moisten or re-wet and fastened down, turn it round
and then cut off the excess. So that is now my frame taped up at the back. Right to finish frame off on the back what
I’m going to do now is I’m going to put felt bumpers onto the bottom and onto the top. So we take the felt bumper, we place it there,
one there, one there, and on the top corners. Bearing in mind that in Italy I know that
you use a hanger from the center here so you would need 2 bumpers on the top. In the UK
we have a hanger there and there with a cord across. If you use that system you don’t need put
bumpers at the top. You only need bumpers at the bottom. And, of course, those bumpers do not mark
the wall and they allow for the free air flow around the actual frame itself. You will find all the products for conservation framing in our web site.
