Handling and Storage

Doors should always be stored flat, ideally in the same room where they are to be installed. They should be protected from damp and dirt and located in an area where they will not be damaged during storage. Leave the door in its protective packaging until ready for treating and fitting.

Doors should not be fitted where extremes of temperature or humidity may occur, e.g. in a newly plastered room. In new build situations the doors should only be fitted when the property is ready for final decoration. Gentle internal heating and good ventilation of the building will greatly reduce the problem.



When trimming a door to fit, 6mm can be removed from each edge of the door to a maximum reduction of 12mm in both the height and width. Any reduction must be removed evenly from each edge of the door, (Excludes Fire Doors – See below).

Three hinges should be used to hang doors, particularly on glazed, heavyweight & fire doors or where large differences in temperature or humidity may occur, such as bathrooms.

Latches and locks should not be fitted adjacent to door mid-rails where the joint may be compromised.

All hardware screw holes should be pre-drilled to prevent splitting of the timber.

Paint 'N'Peel should be left in place until painting or staining has been completed. Some glass styles are smooth on one side and obscure on the other: Please check that the obscure glazed faces of multiple doors are orientated in the same direction, e.g. if installing 2 glazed doors side by side.

Fire doors have individual fitting guidelines and the installer must refer to the Global Assessment Report referenced on the front of this label: These reports can be downloaded from the XL Joinery website; www.xljoinery.co.uk.

Bi-Fold doors are supplied with a track and folding hardware. Instructions are located on the hardware pack or can be downloaded from the XL Joinery website; www.xljoinery.co.uk.



Bare timber doors will require a light sanding prior to finishing.

Take care when finishing glazed doors to ensure that the finish does not go on the glass. Secondary protection such as masking tape may be necessary, including on Paint and Peel protected doors.

All timber surfaces should be fully finished. When applying the finish pay particular attention to sealing the timber end grain on the tops and bottoms of the doors: Ensure that all lock, latch and hinge cut-outs are also fully treated. Refer to the finish manufacturer’s instructions for number of coats to be applied.

Failure to treat all the timber surfaces may lead to excessive changes in moisture content which will cause the timber to shrink or swell, possibly causing splits and distortion.

White Moulded and White Primed doors require a top coat after fitting. They are only suitable for painting.

Factory finished doors will require any bare timber areas caused by trimming and hardware fitting, to be adequately treated before final fitting.


  • Use a good quality paint, stain or varnish.
  • Apply to all faces and edges.
  • Apply the same number of coats equally to the face, edges, lock, latch and hinge cut-outs.
  • Apply at least 1 coat of finish as soon as possible after unpacking the door
  • Check that the finish manufacturers’ product is suitable for veneered / engineered doors


  • Use thin penetrating seals, oils, wax, dyes or hard, brittle finishes.
  • Use thinned / mixed paints or stains.
  • Mix incompatible products, e.g. paint on one door face and stain on the opposite face.


Regular maintenance of the finish must be carried out to ensure the long term protection of the doors. Note: Storing, installing or finishing the product in a manner not detailed in these instructions may invalidate the warranty.
