All of our bespoke products are professionally finished in our dedicated spray shop to give them the best possible start in life. Utilising microporous technology, Teknos finishes are designed to withstand the elements, however due diligence and care will always extend the lifespan of the product. Proper care will not only extend the life of the product, but will drastically reduce the need for serious repair work in the future.

Although our finely finished coatings have been designed to ensure the longevity of our products, the weather will always put them to the test. Conditions vary depending on location, and it is imperative that all joinery is inspected and cared for regularly and accordingly.

Correct and regular maintenance is key to get the most out of any product. Be it a new car that requires regular cleaning to maintain the paint finish and protect it from rust, or a new, painted joinery product, the principle is the same. The more care given, the better the results.

At Richard James, we do everything possible during the manufacturing process to ensure that your product leaves the workshop with the best protection for its life ahead. From then on, as they say, it’s down to you.

Teknos testing suggests that the microporous top coating can last up to 10 years depending on the environment, exposure to the elements and maintenance provided. For example, if a north-facing door is fitted inside of an open porch (or otherwise sheltered), the lifespan of the paint would increase compared to a south-facing door with no porch, which would be exposed to rain, wind and direct sunlight. Therefore, the amount of care necessary for the south-facing door is greater.

Despite what is suggested from tests and findings, we strongly recommend that all exterior products are cleaned and protected twice a year. There is a two-part Teknos maintenance kit available to order through ourselves for £30.00. All of our customers are encouraged to use this, as it has been specifically engineered by the supplier for the job at hand.

The two-part kit both cleans and protects the painted or stained finish. Part one consists of a cleaning solution formulated to remove deposits that collect on the paint over time such as dirt, dust, bird droppings, traffic pollution, and sap which all can lead to a slow breakdown of the paints protective surface.

Once the paint has been wiped down with the cleaning solution and any excess solution has been washed off with warm water, the protective coating can be applied throughout all areas of the painted surface, either by brush or cloth. The coating adds a thin layer of protection and applies a renewed level of sheen to areas which have become dull from exposure.

It is imperative that you maintain your products in order to prolong their lifespan. We strongly advise that every six months, you check your product over for damage such as dents, cuts and splits in the paint surface. Without the product having consistent and fully sealed protection, the natural wood below is exposed to water ingress, which can lead to swelling and early stages of rot.

Please note: the above applies to all timber species including Accoya. Although Accoya has natural elements which help protect it from water ingress and rot, we do still recommend maintaining Accoya products in order to prolong the lifespan of the paint or stain coating and hardware.

If you find that your product has damage to the paint surface and requires the area to be repaired, please follow the steps below:

  • Acquire a good quality, long haired synthetic brush
  • Sand affected area with low grit (320-400) sandpaper
  • Clean sanded area with Teknos solution
  • Rinse surface of solution and residue
  • Dilute paint 5-10% with water in warmer weather
  • Moisten the entire head of the brush to help with paint flow
  • Generously apply a coating with long, diagonal strokes
  • DO NOT OVERBRUSH – Paint will settle and level naturally in time
  • Finish application with light strokes in the direction of the grain
  • Apply 2 or 3 coats of Teknos paint, leaving an hour or so between

Please note: Should our products be intended for commercial application, the expected longevity is diminished due to the unusually high level of stress and wear on the products. Under these circumstances, your maintenance cycle will need to be repeated more often in order to properly protect them.

If you have any questions or concerns, please contact Richard James Joinery for further advice.


In conclusion, every six months you should:

  1. Remove build-up of dust and grime from weather seals and corners.
  2. Wipe down all surfaces with a mild detergent solution and rinse well.
  3. Check surfaces for damage and repair if necessary.
  4. Maintain hardware as per the manufacturer’s instructions.
  5. Clean glass inside and out for the perfect finish.
  6. Pat yourself on the back.
