|All forms of moisture or lack of it, rain, condensation and even atmospheric humidity have a critical bearing on the well being of your door, especially patterns that have solid timber panels.
Here at Richard Potter, although we do not supply domestic doors to the public, we certainly derive no satisfaction from the stressed and sorry state we sometimes see doors reduced to, owing to the ignorance and abuse to which they have been subjected.
When you purchase a door we cannot stress too strongly the importance of following the advice given below, in its entirety.
Ask your supplier about the moisture content levels of your doors, these levels should comply with BS1186 part 1. This provides for external doors to be in the range of 13% to 19% and internal doors 10% to 14%.
For this reason, it is vital that moisture levels are maintained and external doors are not used internally and vice versa. Similarly, solid timber panel doors cannot be recommended for use on south to south westerly elevations without being protected from the direct heat of the sun and the prevailing weather, as by means of a porch or some such similar construction.
We hope you will not scoff at the recommendations that follow and thus avoid the possibility of becoming dissatisfied with the appearance and performance of your door.
- Before attempting to fit your door, you must first take care to select the finish you require and check with the manufacturer, if necessary, that it will give a complete and lasting seal between all component parts.
Many well known brands of wood finish, which may provide excellent surface protection, fail to provide this vital element and may permit the passage of moisture around panel grooves. Avoid use of varnish or polyurethane based products and look for a brand that gives protection against the bleaching out effect of the suns ultra violet rays.
We can recommend Akzo Cetol which gives a high build finish and is proven in this regard. We also supply Sadolin which is very satisfactory for this purpose.
- Immediately upon receipt, sand the door down lightly with fine glass paper (Grade 200) in the direction of the grain to remove nibs and finger marks. Dust down thoroughly and apply at least one coat of your selected sealant to all surfaces, including glazing rebates, also around glazing beads, being sure to follow the instructions.
- Having fitted the door, remove immediately from the hinges, taking off all door furniture and thoroughly reseal where appropriate, paying particular attention to cut outs i.e. hinge recesses, letter plate slots, rebates for water bar, etc. Follow this by a minimum of two or preferably three coats before finally re-fixing furniture and re-hanging.
- Important Additional Advice
- Do not use Linseed Oil Putty - use more flexible compounds/mastics.
- Never fit mortice locks etc., to rail joints.
- Do not use less than a minimum of three off No.4", 100mm hinges.
- Do not fit without suitable weatherboard.
- Future maintenance is most important if the doors good looks are to be retained over many years. We recommend washing down with warm water and detergent every two or three years and re-coating.
