The piano in this Instructable was being used in my wife's Sunday School room, and one day I decided to try to make it a little more presentable. Please note that this piano wasn't a priceless antique -- it was just a cheap old beat-up piano. Although it functioned just fine, as you can see from the photos, it looked like it had suffered through a lot in its life.
Step 1: Materials and Tools Used
The materials and tools used were as follows:
- screwdrivers, wrenches, pliers (to remove the top, front, and bottom panel)
- orbital sander
- large vinyl tarp (to protect the floor)
- shop vacuum cleaner
- wood filler -- LOTS of wood filler!
- sandpaper (150 grit, 220 grit, 400 grit)
- oil based satin black paint
- masking tape
- old newspapers
I also had supervision......lot's of supervision as you can see in the photo!
Step 2: Protect the Part That Makes the Music!
Once the panels are removed, use masking tape and newspapers to cover all the open space from the removed panels and the keyboard. Be fastidious in sealing these areas, because you don't want dust from sanding (or paint) to get into the part of the piano that makes the music!
Step 3: Filling in the Missing Pieces
Once all the chips, dings, and missing chunks were filled, I was ready to begin sanding.
Step 4: Sanding, Sanding, and More Sanding....
For large flat surfaces, I broke out my trusty orbital sander, and fortunately, a piano has a lot of large flat surfaces!
For smaller flat surfaces, and where I had to use wood filler, I block sanded these areas by hand. I began with 150 grit paper, then moved to 220 grit, then 400 grit.
After sanding, I carefully vacuumed the dust from behind where the lower panel mounted, and from all exposed surfaces, including the tarp I had placed on the floor.
Step 5: Painting
Before painting, I carefully wiped down all surfaces with mineral spirits to remove all the dust and to remove any oils deposited from my hands.
Then I got out a set of the best brushes I had and began applying the first coat. I let this coat dry for 24 hours and then lightly sanded it with 400 grit paper, wiped it down once again, and applied a 2nd coat.
Step 6: Completed!
This piano should be good for another decade or two, and hopefully when it once again gets beat up, someone else will come along and refinish it!
This was a simple project, although it did take many hours to complete. All-in-all I worked on it off and on for about four days, including the time required to allow the paint to dry.
