Step 4 Attach Tin to Backing

We need to attach the tin to the backing to hold it in place and protect the poster from the sharp edges. Masking tape is good enough since the frame and pressure from the tabs holds everything in place. OK, gloves back on!

Place and center the tin on the backing. Use small pieces of tape to make it easy to handle and place. Note: it is handy to have your lab/shop/studio assistant hand you pieces of tape since you will be wearing gloves. Let's tape:

(1) Side one
Starting with a long side, rip off a 6-8" piece of tape and overlap it evenly on the tin and backing. Continue down the side, overlapping each piece of tape as you go. (See picture.)

(2) Make sure tin is flat
Make sure the tin does not form any ripples by putting light pressure on the tin and run your "gloved" hand across it from the side we taped. (See picture.)

(3) Side two
Tape up the opposite side just as you did with side one. Always check that the tin stays flat. (See picture.)

(4) Side three and four
Tape up the last two sides as you did with side one. Always check that the tin stays flat. (See picture.)

Note: If your tin fits perfectly into the frame (24 x 36 in. in this case) you will follow the same procedure except that your tape will overlap around the edge of the backing. (See picture.)
