Customers often ask us how long a sand-blasted sign will last, and I tell them this: the paint is the weakest link in the chain. With wood signs, the wood is solid and will last forever (*or at least as long as we're alive), but the paint is going to fade...depending on the sun exposure, somewhere between 10-15 years, you'll notice a real difference in the sign.
Cleaning them once a year with some soap and water is recommended, but sooner or later, the sign will need some new paint. And with a new paint job, it will look like it did the day you bought it.
We recently began a repainting project on the Franklin County school signs...here are some before and after photos to show you what I mean. (Actually, we'd already begun the backgrounding in the maroon area, so that's not exactly a before picture...but you get the idea.)
