Handy Tips

Door Bindings

Variation of hinge gaps may occur in the manufacturing process and generally this will have little impact on door installation. However, once the hinges are removed for painting, problems may occur in resetting doors. Jamb installation is set up to match each door and mixing up of hinges prior to replacement can in some cases severely alter the clearance gap on the closing side. Options are thereby reduced once doors and jambs have finished coats of paint. The following is a preventative measure:

  • Systematically label each hinge, using a felt or a similar marker, print T (top) M (middle) B (bottom) on the back of the appropriate hinge on removal. Position the three hinges against each other and bind together with masking tape or similar.
  • Mark the top of each door opening to ensure each door is returned to its original position and match the marking on the tape binding the hinges

Alternatively

  • Mask around the hinge edges and paint with the door in place. Be aware that use of solvents in removing paint from the hinge surface can result in damage to the protective film.

Be aware of the recess the hinge leaf sits within. It is surprising how much the door clearances can be affected by the build up of paint where the hinge leaves are seated. To prevent further problems, gently scrape out excess paint from the recess.

Care and protection of doors on site

Due to the characteristics of the materials doors are manufactured from it is crucial to take steps to protect them, failing to do so could compromise the manufacturers warranty. Humidity or moisture in the air and/or dampness that escapes from newly laid concrete can create a swelling effect on unsealed doors. This can be evidenced by swelling around the lock block where hardware is fitted and in some cases, the stile and rails making up the structure of the door. Given correct clearances and careful installation, doors can still swell in dimension creating a binding effect. This is compounded with a potential build up of as much as 0.5mm on each painted surface. The following steps can prevent this occurring:

  • Ensure doors are stored in a building that can be sealed from atmospheric variations.
  • Seal all surfaces, including top, bottom and side rails as soon as practicable.
  • Read the manufacturers warranty attached to the leading edge of the doors. This will provide valuable advice and care of your new doors while protecting your warranty rights
