It is recommended to always laminate the print with a UV protector to extend the life of the colors. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Can it be painted?<\/span><br \/>\n            <span style=\"color: #555;\">Yes, although it is factory lacquered. If you want to paint it, it must be sanded lightly and primed to ensure the paint holds. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Is it too heavy for an old facade?<\/span><br \/>\n            <span style=\"color: #555;\">No. A 3mm panel weighs about 3.8 kg\/m2, which is quite light compared to steel or solid wood signs. <\/span>\n        <\/div>\n<\/p><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sunlight-resistant materials for signage Exterior signage is the first impression a customer has of a business.
