Do I need to order crown flexible molding to match a curve or do we order it straight and form it on the job? You will need to order the molding preformed to match your curved wall. Imagine taking a belt and laying it flat around a wall and then trying to bend the ends down toward the floor to create an arch, the belt will buckle and so would our molding.

Painting: No primer coats are needed Most standard paints are compatible. Staining: Thin, watery or mainly solvent base stains will not work well. If you must stain  the molding, be sure to use a heavily pigmented oil base stain, gel stain or artist oil. You can also mix tints or stains into a clear glazing liquid available at most paint stores. Wipe or brush stain to desired color and apply a clear top coat finish. Is flexible molding temperature sensitive? Flexible moldings are a polyester resin based product and are less flexible when stored at  low temperatures. Improper flexing of the material below 56 degrees F may cause breakage. Before installing allow molding to reach room temperature somewhere between 60-80 degrees F. for 24 hours. Can flexible moldings be nailed and glued like regular wood moldings? Yes pneumatic pin nailers work well and even better when nails end are  ground blunt and not pointed. Nails should be kept 6" apart and 3/8" for any edge. Pre-drilling is not necessary when using #6 or smaller finish nails. Some installers use only glue adhesives and no nails at all. Gel Super Glue combined with panel adhesives do the job well when no nails are used. Can flexible moldings be cut, shaped or sanded like wood moldings?  Yes, flexible moldings can be cut, shaped or sanded using standard wood working equipment. Flexible molding gives the appearance of real wood. It is moisture and insect proof.  It can withstand extreme heat and cold temperatures without warping, cracking or deteriorating. Need more help!
