Deziner panels are made from recycled hardwood timber and can be installed outdoors if properly treated and maintained. The panels should be cleaned gently with a feather duster or damp rag. While durable, the panels can break if heavy objects are dropped on them since they are made of small timber pieces. The material is flammable and should be kept away from open flames. The panels can be restained using a water-based product. Deziner panels come with a 12-month warranty covering normal use and damage during delivery but not improper installation, misuse, or transportation costs for replacements.
