Staining or Painting Wood Windows and Patio Doors


How-to stain or paint the interior of your Pella wood windows and patio doors.


A Stained Finish

  • Pella strongly recommends the use of a good-quality prestain wood conditioner before staining Pella windows and patio doors to reduce the possibility of a blotchy-looking, uneven finish. Be sure to ask your paint/finishing professional to recommend a prestain wood conditioner, a stain and a finishing coat that are compatible.
  • Apply the prestain conditioner according to the instructions provided by the manufacturer.
  • Next, apply a good-quality stain.
  • Finally, apply three coats of exterior-grade finish, such as a polyurethane finish.

A Painted Finish

Picking your paint
The most important thing to look for when choosing your paint is good blocking resistance — the ability of a paint to resist sticking. Failure to use a high-quality paint with good blocking resistance may result in a window or door that sticks shut — even after the paint has dried. Ask a qualified paint professional or a nearby extension office to help you find a paint with good blocking resistance. Don’t simply rely on a paint’s price or brand name in making your selection — an expensive paint may not necessarily offer good blocking resistance.

Applying interior finish
  • Ask your paint professional to recommend a wood primer and paint that are compatible — and ask if sanding is required between coats of paint.
  • Read and follow the manufacturer’s directions for using your finishing products. For sliding patio doors, see related article Removing the movable panel on sliding patio doors for finishing.
  • Start by applying one coat of a quality wood primer. Note: If your products are factory-preprimed, skip this step.
  • Next, apply two coats of high-quality interior paint with good blocking resistance.

After finishing with paint, stain or clear coat, allow the windows and doors to cure completely — per the manufacturer’s directions — before closing them or reinstalling patio door panels.
