Veneering on a curved surface can be a difficult process if you don't have the right tool. Inventor Daryl Kiel has created a vacuum pressing system that makes the job easier--the VacuPressB., which literally sucks a surface into place to create curves or attach veneer. Here's an easy method for using the machine to apply veneer to crown molding. Materials:
Veneer
Utility knife
Veneer tape
Foam roller
Water-based glue
Molding
Sponge
Scrap piece of particleboard, larger than the molding
Scrap piece of wood, same length as the molding
VacuPress
- To help the veneer conform to the curves in the molding, use a utility knife to score a horizontal line through the veneer about 1" away from one edge (figure A). Do not cut all the way through the veneer.
- Apply a piece of veneer tape to the back of the veneer on the scored line (figure B), creating a hinge on the veneer.
- Use a foam roller to apply water-based glue to the back of the veneer (figure C).
- Apply the veneer to the molding, with the hinge on top of the curve in the molding (figure D). If necessary, use a small strip of wood to press the hinge into the curve.
- Rub the top of the veneer with a damp sponge to press out any air bubbles (figure E).
- Place the molding on top of a scrap piece of particleboard inside the VacuPress's polyurethane bag (figure F). Close the bag.
- Turn on the VacuPress. The machine will suck all of the air out of the bag and eventually suck the veneer into place on the molding (figure G).
- Turn off the machine, and allow the molding to sit inside the bag for 15 minutes.
