Using our care sets

Teknos Clean and Care sets have been specially developed to care for the factory-finished coating of your Bereco windows and doors. They restore shine to dull and weathered finishes on both hardwood and softwood, can increase the time needed before first redecoration, and will also maintain the all-important timber and finish warranties we offer.

How do I use my Teknos clean and care kit include?

Step 1: Clean

  • We recommend that you clean your windows and doors twice a year, in spring and in the autumn.
  • Apply the TEKNOCLEAN 1951-00 solution using a cloth or sponge to remove dust, grime and insects – paying particular attention to any areas of green algae growth.
  • For light cleaning use 10ml per 8-10ltr of water. For thorough cleaning use 50ml per 8-10ltr of water.
  • Once cleaned with the solution, using a clean lint-free cloth, wipe the surfaces of the finish thoroughly with clean warm water.

Step 2: Care

After cleaning, apply the TEKNOCARE 4250 solution with a clean lint-free cloth. Work the product gently into the frame to restore the shine and to restore the water-repellent properties of the coating.

NB: The product is delivered ready for use so no dilution is needed.

What does my Teknos clean and care kit include?

TEKNOCLEAN 1956-00

A concentrated, alkaline cleaning agent for removal of dirt and grease from painted surface.

TEKNOCARE 4250

A water-based product to restore the sheen on lack-lustre exterior wooden surfaces

Repairing localised coating damage

After cleaning, if localised peeling or flaking, surface damages or cracks are found that have broken the coating, the affected areas should be repaired as follows:

Repairs

Preparation

  • Prepare the area, removing any loose, split, or flaking sections of the coating by using a sandpaper with a p120 grade.
  • Once sanded clean the area with warm water and a lint-free cloth or sponge.

NB: Allow the cleaned areas to dry thoroughly before undertaking any coating application.

Peeling or flaking paint

  • Apply two coats of Teknos Aquatop 2600, in the appropriate colour and gloss level.
  • Allow a minimum of one hour between coats for drying.
  • We recommend that a minimum of two coats are applied but further coats may be needed to sufficiently cover the area

Open joints

  1. Apply a thin layer of Teknos Opti Joint XP, joint sealant at the junction between cills and frames and at the junction between the mortice and tenon joints of the frames and sashes and allow to dry.
  2. Apply a single layer of basecoat using Teknos Aquaprimer 5200-1 for opaque painted finishes and Teknos Aquaprimer 2900 for translucent stained finishes.
  3. Apply two coats of Teknos Aquatop 2600, in the appropriate colour and gloss level. Allow a minimum of one hour between coats for drying. We recommend that a minimum of 2 coats are applied but further coats may be needed to sufficiently cover the area.

Timber damage

  1. Using a two-part wood filler, fill any areas of damaged timber or dents and allow to cure. Once dry, sand the filler to a smooth finish using a p120 grade sandpaper and wipe clean to remove any dust.
  2. Apply a single layer of basecoat using Teknos Aquaprimer 5200-1 for opaque painted finishes and Teknos Aquaprimer 2900 for translucent stained finishes.
  3. Apply two coats of Teknos Aquatop 2600, in the appropriate colour and gloss level. Allow a minimum of one hour between coats for drying. We recommend that a minimum of 2 coats are applied but further coats may be needed to sufficiently cover the area.

Our top tips for effective long lasting repairs.

1. Apply a single layer of basecoat

Apply a single layer of basecoat using Teknos Aquaprimer 5200-1 for opaque painted finishes and Teknos Aquaprimer 2900 for translucent stained finishes.

2. Mix any paint or stain well before use

Mix any paint or stain well before use and check it’s still within its expiry date before applying (our paint has a shelf life of 18 months).

3. Use an angled makeup sponge

Use an angled makeup sponge to apply the paint or stain rather than a brush to avoid over-application and to ensure a smooth and even finish.

4. Use a hairdryer

Use a hairdryer on a medium setting to speed up drying time between coats.

Maintaining moving parts hardware and ironmongery

Bereco timber windows and doors come with high-security espagnolette locking mechanisms and corrosion-resistant fittings and while most are self-lubricating and treated prior to delivery, they do require some regular cleaning and maintenance to ensure optimum product performance and durability.

Bereco window and doors

Entrance and French Doors

All locking points and hinge pins should be lubricated with an acid-free non-resinous grease or oil at 6 to 12-month intervals.

Bifold and Patio Doors

It is essential that the running track for both folding doors and patio doors is kept clean and clear from debris in order to ensure trouble-free sliding and locking. In addition to cleaning we recommend the track should also be lubricated with an acid-free non-resinous grease or oil regularly in 6 to 12-month intervals.

See our folding doors installation guide for further guidance on maintaining your Bereco Folding Doors. www.bereco.dev.plx.mk/customer-care

Casement Windows

Hinges should be checked annually, cleaned of dirt and debris and lubricated with an acid-free non-resinous grease or oil. Espagnolette locking points should be also lubricated every 12 months.

Sliding Sash Windows

When fully factory finished and installed correctly, your vertical sliding sash window should operate smoothly and be virtually maintenance free. If the windows are not opened for a long period of time then it may be necessary to lightly grease the fastener(s) and restrictor mechanism with an acid-free non-resinous grease or oil as well as using a light application of silicone spray in the balance channel on windows operated by spiral balances.

Tilt and Turn Windows

All movable parts including hinges, locking rollers, cams and other fittings should be lubricated with an acid-free non-resinous grease or oil annually.

External fittings and ironmongery

Face-fitted elements like door handles, letter plates, door knockers and numerals should be cleaned every 6 months to reduce the possibility of corrosion and tarnishing of the finish. Each item should be cleaned with warm soapy water and then dried with a soft lint-free cloth to avoid scratching the finish.

In coastal locations, and where windows and doors are installed in swimming pools, we recommend the application of a corrosion preventative after cleaning, taking care to avoid the timber and its coating.

Please refer to the manufacturer’s guidelines received at the time of delivery before undertaking the cleaning and maintenance of any fittings and ironmongery.

Redecoration

Re-decoration is simple to do and you don’t have to remove the entire coating in order to do so. The factory finishing of our windows ensures the longevity of the timber. The key is simply to replace any erosion of the coating with new layers.

First decoration

There are a number of factors that affects when you need to carry out the first decoration. This includes the location of your home and the level of exposure to the elements and weathering that your windows and doors experience every year as well as the coating chosen (opaque painted or translucent stained). As a guide, we anticipate it will be between five and 10 years.

Signs that you need to redecorate

  • Wide spread flaking or peeling of paint from coating surfaces
  • Wide spread colour fading or dulling of the coating
  • Pronounced or raised grain where it wasn’t previously noted

Follow the below guidelines to ensure a smooth and lasting finish

1. Cover the work area

Cover the work area. Taking care to avoid getting paint on the glass and fittings.

2. Clean all window and door surfaces

Clean all window and door surfaces using Teknoclean 1956-00 solution from our clean & care sets.

NB: Do not use the care solution when redecorating as this may affect the adhesive of the coating.

3. Remove sashes and door leafs

Remove sashes and door leafs where possible for ease of application in corners and to prevent painting the windows shut.

4. Key the surface of the coating

Key the surface of the coating by using a p250-grade sandpaper. Once sanded clean the area with warm water and a lint-free cloth or sponge.

NB: Allow the cleaned areas to dry thoroughly before undertaking any coating application.

Apply two coats of Teknos Aquatop 2600

Apply two coats of Teknos Aquatop 2600, in the appropriate colour and gloss level. Allow a minimum of one hour between coats for drying. We recommend that a minimum of two coats are applied but further coats may be needed to sufficiently cover the area.

Care and Maintenance FAQ's

Can I use other cleaning products to clean my windows?

We recommend using only our approved Teknos Clean and Care sets to care for the finish of your windows and doors many cleaning products contain ammonia – a corrosive agent that can cause damage to the glazing and the coating.

I've noticed when cleaning the silicone around the glass on my windows that it is damaged, how do I repair it?

We recommend using only an experienced tradesperson when undertaking the removal of the silicone surrounding the glazing as this creates a watertight barrier between the glass and frame.

I've noticed when cleaning the seal between the window frame and the building is broken or has gaps, how do I repair it?

We recommend using only an experienced tradesperson when undertaking the removal and replacement of the silicone surrounding the window frame as this creates a watertight barrier between the window and the building.

What is the best time to redecorate my windows and doors?

The optimum temperature for application of our paint and stain is between 5°C to 18°C so we would recommend doing any redecoration in spring or early summer.

How do I know which colour my windows and doors are finished in?

The colour of your windows and doors can be found on the specification pages of your order confirmation. It will start with the prefix of either RAL, BS, NCS or if you opted for a Farrow & Ball colour-matched paint the Farrow & Ball colour code and name will be detailed on your order. 

If you are unsure please get in touch with us via email at customercare@bereco.dev.plx.mk or via the live chat icon on our website www.bereco.dev.plx.mk.

Can I use another manufacturer's paint or stain if it's water based?

We recommend that you use only the Teknos coating system so we can continue to offer a warranty on your timber windows and doors.

How much paint do I need for my redecoration?

Typically, one litre of Teknos Aquaprimer will cover a surface area of up to 8 metre squared and the Teknos Aquatop 2600 topcoat up to 6 metre squared.

How do I order paint or stain to carry out my redecoration?

We can order any additional paint or stain for you and have it delivered to your door within 3-5 working days. To order more paint or stain please call our offices on
01709 357082
 or email us at parts@bereco.dev.plx.mk.

What do you recommend for covering the windows during redecoration?

You can use a glass protection film to protect the glass during redecoration but we recommend that any protection is removed immediately after completion and left on no longer than two weeks. We do not recommend the use of any adhesive tapes on either the glazing or coated surfaces of our windows and doors.

Can I change the colour of my windows and doors?

Your windows and doors are designed to last 60 years and we know that taste and trends change so don’t be afraid to change with them. We can colour match any RAL, BS, NCS or Farrow & Ball paint colour, so if you fancy a colour change for your windows and doors just tell us the colour you would like to match on ordering.

Can I replace the glazing in my windows and doors?

Our glass is not bonded into the frame like it often is with uPVC, so our windows and doors so can be easily re-glazed. If you need to replace the glazing at any time, we recommend using an experienced tradesperson to do so.
