Reversible Koma trim boards are a polyvinyl chloride (PVC) material that won’t swell, rot, split, delaminate or cup under harsh conditions.  Nice wood texture on one side and a satin smooth finish on the other.  You can nail, glue, drill, rout and cut KOMA Trim boards using the same tools you would use with wood.  KOMA Trim boards are UV-resistant and do not require paint for protection. If painting is desired, do not use a dark color where KOMA will be exposed to the sun.  Exterior graded hardware and glue can be used, but it is not recommended to use a silicone based product.
