Using your metal tropical house number sign is super easy. First, find a spot indoors or outdoors where you want to hang it. Since there are pre - cut holes, you can use a nail or a screw to hang it up on a wall. You can customize your sign by choosing from 15 different powder - coat finishes and 5 fonts to make it truly unique. When it comes to maintenance, these signs are powder - coated, which means they are durable. But it's still a good idea to clean them gently with a soft cloth every once in a while. If it's an outdoor sign, make sure it's not constantly exposed to extreme weather conditions for long periods.
