How to restore a mural

This past weekend my neighbors and I spent the first nice day of 2014 outside on New Market street fixing up a mural that had recently been tagged with non-artistic and very unwelcome graffiti. It is sad that some people have no respect for the murals that exist in this city, but it's just a part of urban living that nice things can get destroyed. Thankfully, we were able to make a huge dent in fixing the mural up just in one short day.

As you can see from the photo above, the tagging was really extensive. Restoring it was a daunting task--I have never tried to fix a mural before, let alone one spanning about 40 feet across and 10 feet high. I even researched on the internet for tips and guides on how to restore, but there really were no clear cut guidelines that I could find to reference for help. It isn't a perfect method, but here is what I found to be the best way to fix an outdoor mural painted on a concrete surface that's been defaced with graffiti. Also, it is important to make sure you have permission to fix the work up. If the mural belongs to the city or an organization, contact them first. This mural was done by a local resident years ago and is not affiliated with Mural Arts of Philadelphia.

Goof-Off or similar graffiti cleanup spray can be effective to remove the spray paint. You can also purchase environmentally friendly paint remover in large quantities if the paint has been dry for too long and something stronger is needed. I have tried many different products to remove paint, and the easiest, safest and most effective so far is Motsenbocker's Lift-Off, which is also biodegradable and water-based. 

Materials:

Rubber gloves

Ventilation mask

Protective eyewear

Clothes you don't mind destroying 

Small Rags

Old towels

Coarse scrub brushes 

Coarse scrub pads 

Trash bags

Small, sturdy plastic trays (frozen dinner trays/takeout trays work great)

Painting Materials 

Medium or good quality acrylic brushes (Sturdy, synthetic bristles with flat or filbert head)  

A few regular sized house paint brushes 

Paint rollers and trays if needed

Drop cloths 

Buckets with warm water 

Acrylic paint - some can be the tube or tub kind you get at the craft store (these colors are brighter and the paint is thicker) some can be the gallons and half gallons of house paint (the color will be more subdued but the paint goes further--good for large areas of block color). We used both depending on the color. 

Clear sealant/non-yellowing topcoat (for easy removal of future defacing)

I decided we needed to remove as much of the spray paint as possible because we really couldn't see the details of what was underneath without at least trying to strip off a layer. There was a lot of detail on this black and white striped globe, pictured below.The bright tag with black outline on the left was done with silver spray paint, which had to have been the most annoying color to remove. It has a slimy texture and it gums up when the paint remover is applied. You shouldn't need to use a whole lot of effort to see the graffiti begin to vanish.

When you've removef all the graffiti you can, let the surface dry for 15 minutes and begin the painting process. Don't be discouraged if there are layers you can't get off; that is when painting over the damage comes in!

Mixing Color 

Starting with the closest color you have on hand, you'll then adjust the color and saturation. For this blue, I started with a sky blue house paint and toned it down with white, and added a bit of bright yellow to bring it to a slightly more sea-foam color. Paint is always lighter when it is wet, so it should look a shade or two lighter than the color you're trying to match.

(Here you can see my test batches applied onto the original color. The top right corner was the winner after I added a tiny bit of yellow)

If you can't match the paint exactly, consider painting over it with a similar tone that you have on hand. Some colors I didn't have (navy blue, brownish-maroon) so I just matched with what I had (dark blue, and as close to maroon as I could get). Look up "color theory" or "how to mix paint colors" for a basic guide. (And throw out that red/yellow/blue theory while you're at it)

The restoration isn't finished but we got a good chunk accomplished in one day! 

Spring Window Paintings - Reverse Glass Technique

Window painting is a fun and eye-catching way to spruce up the window of a local business, and is also a unique and creative way to advertise your space. Changing the artwork every few months is a festive way of transitioning from one season into the next. Here, I swapped out the winter scene of the Druid's Keep into a floral toast to nature in the woods. I'll be making some adjustments (adding some birds, making the pint glass bigger and adjusting the bottom of his cloak) but here's the first version.

Reverse glass painting is an easy concept to grasp but a challenging technique to apply. A painter is used to putting down the larger blocks of color first, and the details and accents last. Your mindset must flip-flop in order to make a reverse glass painting visually successful. You also have to have a good idea of what knowing how the painting looks from the outside, since as you are painting you're looking at the back of the image. It's not uncommon for me to run outside in between layers to make sure what I'm putting down looks "right." (That's how you know I'm still an amateur!) The details and outline are created first, so you really have to know exactly what you're going for, otherwise you'll be painting, wiping off and repainting until you get it right. 

You can see that my mistakes here were matching the color of the Druid's robe, walking stick and tree (since I kept him for the winter scene, I was attempting to match the old paint color). 

From the inside, it looked like the same color; when I popped my head outside, I realized I was way off! I also got the scale of his pint glass wrong (for now, the Druid will have to suffice with a half-pint of Cider).

For these floral paintings at Inner Beauty Salon in Bristol, PA, I did the bright green streaks of grass first, followed by the yellow dot of the flower buds. Then, I painted a darker green outline of the leaves, and a layer of darker green grass behind the brightest green. Next, I outlined the flower petals in a darker, bolder color. The final details are a lighter color inside the petals. 

To get the paint off, I used a paint scraper, textured rough sponge and water. I found this latex-based paint remover spray to be very effective in loosening up the layers of paint to remove from the window.
