The first step in maintaining exterior foam molding is to clean it regularly. Dirt, debris, and pollutants can accumulate on the surface, which can cause discoloration and damage to the material over time. You can use a soft-bristled brush or a low-pressure washer to remove the dirt and debris. Avoid using harsh chemicals, as they can damage the material. Instead, use mild detergent and water to clean the surface.

Inspect for Damage

One of the most important maintenance tasks for foam molding is to seal the joints. Joints are the areas where two pieces meet. Over time, these joints can become loose, which can allow moisture to seep in and cause damage to the foam. To prevent this, you should seal the joints with a foam-compatible sealant. This will help keep moisture out and ensure that the material lasts longer.

Protect from UV Rays

UV rays from the sun can cause the foam to deteriorate over time. To protect it from UV rays, you can apply a coat of paint or a UV-resistant finish to the surface. This will help protect the surface from sun damage and keep it looking like new.

Trim Landscaping

Landscaping can be a beautiful addition to any home, but it can also damage molding if it’s not properly maintained. Overgrown plants and trees can rub against the surface and cause damage to the surface. To prevent this, make sure to trim your landscaping regularly and keep it away from the foam. This will help prevent damage and keep the molding looking great.
