Decorating Your Door: Advice on how to properly decorate & protect your new door.

Unless otherwise stated, usually by a phrase such as ‘prefinished’ or similar, any timber product we sell will be shipped ‘in the white’. This means that it will be bare raw timber and needs to be decorated on site by you or your installer/decorator.

Any product supplied in the white should be fully decorated prior to installation. Yep, you read that right, decorate it BEFORE you fit it. We aren’t saying that for fun either, we really mean it; if you want your door to last then you need to do this. If you don’t do it then you can expect a failure pretty quick.

Any cut-outs made for locks, hinges etc. and any edges which are cut to suit during installation will need to be fully coated as detailed below. A simple quick once over is not adequate for these areas, and they must be fully decorated.


External Doors

Before painting/staining your door, pin holes on beading etc. should be filled using a filler which will match your desired colour. You should ensure that this will stain to the same shade you are wanting to achieve on the entire door.

External Doors, frames and panels may be treated with a spirit based Microporous treatment of quality exterior grade.

If staining, then one base coat and three top coats are required. Some products allow for the base coat and top coats to use the same item. One example of this is the Sadolin Extra Durable Clear Coat

If painting, then a spirit (or Aluminium) based primer, 2 undercoats and 2 top coats, again spirit based, must be used and must give protection at least equivalent to the Sadolin Extra Durable Clearcoat mentioned above.

N.B. Note that a primer coat or base coat alone is not sufficient to protect timber products even for a short period of time.

Be sure to seal inside lock and letter box cut outs, behind hinges, both the top edge and bottom edge underneath the door, and door sides to prevent moisture entering the timber. Decorate behind all draught seals and thresholds. This is because the timber has a specific moisture content that must be maintained. Failure to do so will void your warranty.

Both sides of the door should be done at the same time to ensure correct moisture content is maintained throughout the entire thickness of the door. Failure to do this can result in one side drying out causing the door to bow.

A pigmented treatment should be used to protect the timber from ultraviolet rays. Any clear treatment used must be a spirit based microporous treatment and specify that it offers UV protection.

NEVER use any of the following types of products: -
* Water based, be it a varnish or paint (eg. Ronseal Quick Drying Woodstain)
* Natural oil (eg. Teak oil, Linseed oil, Danish oil, Vegetable oil, Soya Bean oil etc. or any product based on these)
* Wax (eg. Briwax etc.)
* Varnish (eg. Yacht Varnish). Please note that Sadolin Outdoor Varnish is suitable in areas where doors are covered by a canopy or inside a porch, but not otherwise. This is because it lacks a pigment so is not as durable as the alternative products mentioned below.

We do not consider these to give adequate protection and no guarantee claim will be entertained for goods treated with such products. These will cause adverse effects to your doors and void your warranty.

Instead, we advise the use of the following products or similar: -

Pre-hung External Doors

When you order your door (and panels) as a Pre-Hung Door set then further steps should also be taken.

Your door set should be fully disassembled. By this we mean that all hinges, handles, locks, thresholds, draught seals etc. should be removed.

Your door, frame, panels and any other woodwork should then be fully treated as per the above decorating instructions.

Upon fitting, and reassembly, your MUST ensure that the aluminium threshold is sealed using silicone where it meets the frame.

For guidance, we will supply an instructional leaflet with your products, which shows how to do this. A downloadable copy is also available by clicking the link MXS Cill Apply Silicone Sealant.

This leaflet shows the Stormguard Mobility Access Cill However, this procedure applies to ANY other threshold you may have requested to be used during manufacture.

Internal Doors

Before painting/staining your door, pin holes on beading etc. should be filled using a filler which will match your desired colour. You should ensure that this will stain to the same shade you are wanting to achieve on the entire door.

Internal doors can be treated with paint or varnish type finishes. Some types such as the oak engineered internal doors may be treated with Oil which have been specifically designed for use of doors or have been extensively tested on them (for example Briwax Danish Oil, Osmo Door Oil, or similar). Be sure to apply four coats to a new door and fresh coats periodically.

NEVER use any of the following types of products: -
* Water based, be it a varnish or paint (eg. Ronseal Quick Drying Woodstain)
* Natural/Plant oil other than those mentioned above (Vegetable, Soya Bean, Linseed oil etc. or any product based on these, unless specifically formulated for use on doors).

These will cause adverse effects to your doors and void your warranty.

Please note: Doors in high humidity areas such as airing cupboards, bathrooms and shower rooms etc. require a treatment that will protect against such high humidity. An external quality treatment may be required to maintain the correct moisture content as mentioned below otherwise the door may fail if excess moisture is absorbed.

Be sure to seal inside lock cut outs, behind hinges, both the top edge and bottom edge underneath the door, and door sides to prevent moisture entering the timber. This is because the timber has a specific moisture content that must be maintained. Failure to do so will void your warranty.

Both sides of the door should be done at the same time to ensure correct moisture content is maintained throughout the entire thickness of the door. Failure to do this can result in one side drying out causing the door to bow.

These are some suggestions but before applying wax or Danish oil you MUST contact the manufacturer before using to ensure suitability.

We are stockists on both Briwax Danish Oil and Briwax Original Wax Polish. See our Decorating Products section for more information.

Pre-Finished Internal Doors

Pre-finished doors are delivered, for the most part, without the need for any decoration as they are already coated.

However, for lock cut outs, behind hinges, and where the doors have been trimmed to size during fitting, we would suggest using the following product on the newly exposed area of your door. Although not a perfect match, it is the closest match we have found that is available in the UK.

Further Information Regarding Coating Of ALL our products

Regardless of how many coats any particular treatment product may say is required, our terms and conditions require the minimum as detailed above.

Important

We are not able to give advice on every individual decorating product available on the market as we cannot hold information on each and every product sold. You should seek assurances from the decorating product manufacturer that it will meet the criteria set out in this document. The main point is that it should be able to maintain the correct moisture content of the timber used in the manufacture of the door and not allow it to vary by more that 2%.

The coating should be maintained to a minimum of 105 microns. In real terms this means that if you have a door with very little glass, for example the Modica Exterior Door then you should have very little or non at all left from a 1 litre tin of Sadolin Extra Durable Clear Coat if applied correctly. You may even need more depending on how the grain of the timber has soaked up the treatment. You should NOT be able to feel the grain of the timber through the treatment. This is the same for frames.

If any door (and/or frame) manufacturer has given finishing advice then this must be adhered to over the advice given above. This especially applies to items such as external doors when being fitted in internal locations. Such doors may require an exterior quality finish when fitted internally.

We advise that clear varnish is not used with hardwood (including oak) doors. By this we mean that within our website many doors are termed ‘hardwood’ and a specific hardwood species in not given. In this case there may be different species or sub-species used in the same item. While these may be very similar in colour prior to varnishing/treating they may be completely different after treating. Clear varnish can exaggerate this difference. By no means will a coloured stain/varnish eliminate the possibility of this but it does reduce the risk. Such a colour difference is not considered a defect. More information on this is detailed in our Terms page.

Cutting In

Do NOT use masking tapes on any textured, etched, coated or otherwise treated face of any pane of glass. Masking tape is ok for use on clear glazing, but the glue will adversely affect the glazing if applied to glass such as, but not limited to, Satin, Sandblasted or Silkscreen faces. Instead the decoration should be applied and ‘cut in’ to the edge of the timber with great care not to get any on the surface of the glass.

Pin Holes

Normally we will provide pin holes in beadings and mouldings unfilled. This is to ensure you can match the filler to your chosen colour of decoration.

In the past, we have filled pin holes with filler matching the bare timber, only to receive complaints that this does then not match after the door is decorated. If we put in a darker shade of filler, and the doors are clear waxed, we receive the same complaints but because the filler is too dark. Similar applies for customers who want to use a very dark colour decorating product.

We cannot pre-fill the pin holes with something that matches all suitable decoration products while ensuring that all customers tastes and preferences are matched.

A clear varnish/stain can exaggerate the colour difference between the timber and the filler. A coloured stain does tend to help any filler match better. If any pin holes are not filled these should be done with a weatherproof filler, if external, and the colour chosen to match your final treatment. We can supply small off-cuts of timber if required so that you can test your filler and decoration together before applying to the doors.

Glue

While every effort is made to ensure all traces of adhesive are removed from the door, unfortunately sometimes there may be traces which remain after cleaning and sanding. This is not considered a defect. Often these are not visible until the first coat of treatment has been applied. If any glue marks show during application of the first coat then immediately sand the area using a fine grain sandpaper or wire wool to remove them; then quickly re-apply the treatment used.

Maintenance

Regular maintenance of coatings is a must. Over time UV rays, weather, as well as general wear and tear, will break down the decoration on the products. This is the same for all treatments that may be applied or are factory applied. Application of top up coats should be applied with a maximum duration between each coat of 18 months. However this will vary depending upon your location and the wearing of the coating. In some circumstances, especially on south facing installations, it may be required as often as every 6 months as UV Rays in the sunlight will breakdown the coating. While not essential, we do recommend a canopy in these situations to help shelter the door from harsh sunlight, which will reduce the frequency of maintenance required and give the door and it’s finish a longer lifespan.

Notes:

This entire section is important and forms part of our Terms & Conditions. This page should be read in conjunction with our guidelines in our Storing Your Door section. Failure to comply with these guidelines will invalidate your warranty.
