Use and Care Manual
The care and nishing of your new interior doors should be taken very seriously. Though these suggestions may sound basic,
most damage to interior doors is caused by improper, careless handling.
Wood doors should be treated like ne wood furniture.
Doors stored for more than a few days should have the top and bottom rails sealed. Do not drag doors or walk on them.
Single door slabs (not prehung doors) should be laid at on a dry, clean surface.
Do not subject them to extreme or rapid changes in humidity or heat.
Finishing:
Proper care and nishing are very important to gain the maximum benets from your interior doors. If done right, a correctly
applied nish will help you achieve a longer lasting higher quality product that exceeds your aesthetic and operational
expectations. Below are a few key points everyone should know when it comes to the care and nishing of interior doors.
All doors have six sides - not two, not four, but six – front, back, two edges, plus the most ignored and most vulnerable,
the top and bottom. Failure to nish all six surfaces uniformly is the number one cause of door failures.
No nishing process exists today that totally eliminates the transmission of water vapor or moisture into and out of
wood doors. The key to proper nishing is to slow down the transmission process so the door performs within
tolerances.
Sanding is a critical component of any nishing process. All doors may have visible and invisible blemishes from
handling or other natural occurring characteristics. Sanding techniques vary by door type and must be followed to
achieve a quality nish.
Natural wood doors (pine, poplar, oak, etc.) contain color, tone and graining variations that occur in the natural
process. Application of a pre-stain wood conditioner promotes a uniform appearance and minimizes sharp color
contrasts. Carefully follow manufacturer's instructions for wood conditioner application.
Oil based products are recommended for interior wood veneered doors. Water based products can raise the grain
and cause multiple moisture related problems. Latex or oil based paint is suitable for interior molded doors.
