How to float mount prints with spacers – LION Picture Framing Supplies

Adding a spacer creates depth between the glass and mount/backing board to accommodate an object or float mounted artwork. Econospace is a quick and simple solution for depths up to 9.5mm, the adhesive bonds to the glazing. Wooden spacers are available that match many of our popular frame finishes, and also in bare wood, to create space gaps up to 52mm.

Step-by-step instructions

Step 1: Measure the frame depth

Ensure the spacer is tall enough. The height needs to leave enough room in the frame rebate for the glazing, mount and backing board.

Step 2: Choose a spacer

Ensure the spacer isn't too wide. It should be no wider than the moulding rebate so that it's not visible from the front.

Step 3: Cut and build the spacers

For smaller frames; measure the longest side of the frame. Cut two pieces of spacer to this length using a Fillet Cutter.

Step 4: Fit longer sides

Place the glazing into the frame. Apply double-sided tape to each piece of the spacer and stick to the inside of the frame, touching the glazing.

Step 5: Fit shorter sides

Measure the shorter sides of the frame and repeat as before. Trimming two pieces of spacer and fixing them in place.

Step 6: Complete the frame

Complete the rest of the frame as usual.

Step 7: For larger or heavier frames

If the frame is larger or heavier then a different approach is needed. The spacer is joined to add rigidity.

Step 8: Measure the frame

Measure the inside of the frame, cut the spacer to match the glass size. This can be done on our Chop Service.

Step 9: Join spacer with underpinner

Join the spacer frame on an underpinner then drop it into the frame on top of the glazing.

Step 10: Complete the frame
