How to Bend a Baseboard
- 1). Make a steam chamber. Whether you use a PVC pipe, or you build a box from plywood, make a chamber that will contain the length of your baseboard. If you use PVC pipe, enclose the ends with plastic bages and duct tape. If you make a plywood box, nail it together with a hammer and a few finish nails that you can remove easily. The box doesn't need to be fancy, just large enough to hold your trim. A Sonatube with trashbags duct-taped over the ends will work just as well.
- 2). Saturate the chamber. Some surgical hose connected to a tea kettle will work, if your chamber is close to your kitchen. Remember that steam entering the chamber will quickly condense into water. You need a vent for the steam to pass through.
- 3). Steam the baseboard and allow it to enjoy its personal sauna for two to four hours. The board should come out of the chamber feeling like a piece of linguine al dente.
- 4). Mount the baseboard directly to the curve you're conforming to, if possible. Otherwise, you will need to clamp the baseboard to a jig that imitates the wall's curve. The baseboard will dry and hold its new form.
- 5). Make relief or "kerf" cuts into the back of the baseboard, if the trim is particularly thick. Make these shallow cuts evenly but closely spaced on the backside of your trim.
