Yes. Our coating is similar to the heavy-duty sealant used in truck-bed liners. It protects against impact and abrasion, making our letter sculptures weatherproof—and with a little care and common sense—very durable (but not indestructible). For instance, you should never leave foam letters out for extended periods of severe weather.
Like plastic deck furniture, letters left outside will require more cleaning to keep them looking new-especially if your sculpture has a lot of nooks and crevasses for water to collect. If you want letters that can be left outside long-term, tell us during the quoting process so special construction and sealing precautions can be made.
