Installing Polyurethane & Crown Mouldings
Polyurethane products are shipped primed and ready to paint. A good quality exterior paint is recommended. Polyurethane products are installed in a similar fashion to wood products. Use quality adhesives or screws. Counter sink screws and fill screw holes with exterior fillers.
PVC products are equally as easy to work with. You can use screws, nails and many construction adhesives. If you are fastening PVC trim boards together, use PVC cement, which is widely available. PVC does not require paint, however if you wish to paint, use 100% acrylic latex for best results.
