Actually, LexArts already thought of that.
"We will be using two layers of permanent clear coat that will protect the murals from UV rays and allow for graffiti to be removed," LexArts community arts manager Nathan Zamarron said in an e-mail.
Zamarron said they had to take the conditions the murals would be displayed in into consideration when selecting a protective coat. The mural at Al's Bar on North Limestone, for instance, will have the most sun exposure, so they selected a specific combination of protective materials that will help keep the mural from yellowing over time.
"The employees at Golden Art Supplies are very good at suggesting specific materials for a given situation," Zamarron said.
There is also a bit of an ethical protection too, Zamarron said. In talking to other communities, he said they heard graffiti artists tend to respect artwork and leave it alone. That's a nice attitude, and hopefully it proves true in Lexington.
Note: The North Limestone Neighborhood Association is having a dedication celebration for the Al's Bar mural, painted by Michael Burrell, from 5 to 9 p.m. Saturday at 6th Street and Line. Musicians will include Lexington jazz legend Byron Romanowitz, and the mural will depict the musical heritage of Limestone. The event will be a fundraiser for a music stage in Duncan Park and musicial outreach programs for childreen in the community.
