Conventional tools for cutting, drilling and nailing can be used with Deckorators railing. We recommend using a sharp, carbide-tipped saw blade for cutting. For your safety, remember to wear protective clothing and safety glasses. Reference the Railing tab on the Installation Instructions page for railing instructions specific to each product line.

Glue is a supplemental adhesive and should never replace a fastener, especially in structural applications. Heavy-duty construction adhesive can be used, but we recommend testing on a small portion of your deck before using the adhesive throughout your whole application.

Periodic washing with soap/detergent and water will help remove surface dirt. It is always a good idea to test the cleaner in a small, inconspicuous area prior to applying it to the entire railing system. A pressure washing should not be used to "blast" soils from the railing surface. A pressure washer with a fan-tipped nozzle should be used only to lightly wet or rinse railing surface.
