I had a friend spray paint a beach/universe scene on my shaved ice stand. What kind of coating/preservative/varnish can I use to prevent the paint from peeling/fading?What can I use to preserve the graffiti/spray paint on the side of my shaved ice stand?
I worked as a finishing specialist for 25 years and I can tell you that the preparation before the initial application was the most important thin to the longevity of the paint job. Since that is now a moot point, I suggest that you first find out what kind of paint was used. If it's enamel ( which it probably is) then you need to apply enamel over it. DON'T apply Lacquer to an enameled surface, it will make it wrinkle. If you could get your hands on an automotive clear coat like polyurethane or an acrylic urethane, that would be great, Body shops would be a place to look and of course, they would need to be applied with pro painting equipment. If you don't want to go to this extent, use a clear coat of the same brand of paint that was used for the graffiti. This should extend the life of the work for some time. More coats periodically will help also.What can I use to preserve the graffiti/spray paint on the side of my shaved ice stand?
Krylon makes a clear acrylic spray with U.V. shielding properties that I use frequently. Good stuff ! You can get it at Michael's.
i used to graffiti furniture for a lady who sold it in Camden Market.I just coated it with a spray lacquer when i finished.It worked well and also brought the colours out more,
Wow...this is a good question...Many of the products that you could use will yellow the original finish and you certainly would not want that. My suggestion would be to go to a reputable paint store and explain to them just what you are trying to accomplish. Ask Sherwin Williams.....!
