Solid Timber Door Blanks Site Storage, Protection & Conditioning Guidance

In order for timber door-blanks to perform satisfactorily in use, it is essential that the following guidance is adhered to, both prior to and following installation:

  1. Sealing and priming of doors should be carried out immediately after delivery to site.
  2. Doors should be given further coats of paint within a reasonable period of time, and certainly within 1 to 2 days maximum.
  3. The top and the bottom edge/s of the door should be sealed along with any surface subsequently cut. This is particularly important in the case of any cut, which exposes end-grain, which should always be primed before the door is fixed into position.
  4. Prior to fixing, doors must be stored horizontally and supported by at least 3 equally spaced level bearers.
  5. Solid Timber Core doors being used as external doors MUST be lipped all round with minimum 6mm thick hardwood, securely fixed using an exterior glue, and adequately sealed on all edges and faces prior to final fixing.
  6. In buildings where a high humidity content exists and where a consequential “drying out” of timber will occur, special precautions must be taken to avoid a build up of moisture during storage.
  7. In buildings where central heating and / or other forms of continuous heating is installed it is imperative that the manufacturers guidance/advice is followed (for more information please visit This point is particularly relevant in colder seasons where central heating may be used to dry out new plaster etc.
  8. Testing of the central heating by switching on and off during construction may be detrimental to performance. Instead, heat should be increased gradually over the maximum period possible.

Summary – Conditioning
Suitable product preparation and conditioning to the installed environment in accordance with this guidance is imperative to achieving satisfactory performance. Inadequate preparation and insufficient conditioning during storage could result in movement to the door after installation. If there are any special circumstances applying to storage conditions and / or fixing these must be considered by the purchaser and made known to the manufacturer at the time of ordering.

Unless the above guidance is closely adhered to, the supplier may disclaim liability in the event of performance or product failure relating to postinstallation product movement. For full technical information please visit
