Finishing & Care Information
The timber components used on the door are dried to specific moisture content
during manufacture. Exposure to damp or moist conditions will cause swelling of
the components, discolouration and consequent distortion of the door.
Both faces of this door are primed. To reduce the risk of distortion all unfinished
edges MUST be sealed BEFORE hanging including cut outs.
These doors are only suitable for a paint finish.
You can use water based or solvent based primers, undercoats and paints to

finish the door. If using a solvent based finish we recommend the use of a VOC
2010 compliant product. Always follow the primer, undercoat or paint manufacturer’s instructions with reference to number
of coats and drying times.
As with all doors, care must be taken to ensure that doors are not installed in buildings immediately after plastering or other
wet trades have taken place.
If the door is to be reduced in size, an equal amount of timber should be cut down from either side, top or bottom.
Please note this must never exceed 12mm in total, 6mm each edge, top and bottom.
If the door weighs more than 20kgs or is subject to large differences in temperature or humidity on each side (e.g. bathroom
or airing cupboard) it should be hung on 3 hinges.
When fitting a standard core door pay special attention to the position and size of the ‘lock block’. This is a solid area 360mm
high x 65mm wide, positioned halfway down the door. The word ‘LOCK’ appears on the top edge of the door to show which
edge the ‘lock block’ is located. Please note if the door is a ‘Developer’ construction then ironmongery can be fitted either
