I was getting ready to throw away an old cheap glass-top patio end table when my wife came up with the idea of covering it in pennies. Since I really hate to ever throw anything away, it naturally seemed like a good idea.
Step 1: Gather your supplies
Second, I used an adhesive that works on non-porous surfaces (I used Goop, but other similar adhesives should be fine).
Third, I didn't count them, but I probably used about $4 worth of pennies.
And finally, I used grout. I happened across a pre-colored bag of grout that was marked down substantially, so this worked for me.
I also used some cleaner to clean the table, a putty knife to spread the grout, and damp sponges and paper towels to apply and finish the grout.
Step 2: Start gluing
After gluing down all the pennies, we let the glue cure per the manufacturers recommendation.
Step 3: Add the grout
Since I was doing this part by myself, I wasn't able to photograph the process, but it was pretty simple. I placed a bit of the grout mixture on the table and forced it into every gap with a plastic putty knife. After covering all gaps, I then let it sit for about 20 minutes.
Next, I took a damp sponge and begin wiping the grout off the pennies, cleaning the sponge frequently as I progressed. After cleaning all the grout from the tops of the pennies. I wiped them down with a dry paper towel. All that was left was to let the grout cure overnight.
Step 4: Let the grout cure
By the way, before anyone feels a need to tell me I violated federal laws by defacing coins, there's no need. No coins were defaced in any way (not cut, nor drilled, nor anything else). All the coins are still intact. No coin was harmed in the making of this table......
