MAINTENANCE INSTRUCTIONS

Table of Contents

1. Introduction

We manufacture and install wooden windows and doors of highest quality. We use high-quality materials which we process with greatest care.

You, as our customer, will experience joy with our products for many years if the windows are protected in the construction phase and the following maintenance instructions are adhered to. As the case may be, neglected protection or improper cleaning of the paint and stain surfaces may lead to irreparable damage already during the construction phase.

We would gladly take the annual maintenance of your units in hand. In combination with a maintenance agreement - we then extend the warranty period to 5 years. We would be glad to be granted the opportunity of drawing up a quotation.

2. Protection of the Elements

2.1 Why is protection necessary

During the construction period the elements may, among others, be damaged by improper operation, by contamination and by unprofessional cleaning. This damage is in part irreparable (e.g. scratched glass)
If damage is incurred the financial and time input is always very high to eliminate this said damage.

If protection is adequate and carried out consequently, damage can be avoided. This is the only way by which elements can be handed over in a perfect condition upon termination of the construction period.

Please observe our cleaning instructions for elements drawn up under Point 3. Please also inform your architects, construction site supervisor and the craftsmen at your site who are involved in the construction work correspondingly.

Should you have questions in this connection, please contact us.

2.2 How can protection be handled

If necessary (when work is being carried out next to the window or in the vicinity) and/or construction dust accumulates, the windows have to be protected by a plastic foil or a plywood cover.

Protection of the units is the responsibility of the subsequent trade.

3. Cleaning and Maintenance Instructions

Regular cleaning and maintenance is the prerequisite for a long life and the perfect operational operability of these high-quality products.
The cleaning and maintenance agents must be adjusted to the materials we have used.

Generally acids (e.g. diluted hydrochloric acid), detergents containing solvents and abrasive detergents may not be used as they can cause irreparable damage.

3.1 Glass

3.1.1 In the course of construction

Generally any aggressive contamination is to be avoided in the course of construction. Should contamination nevertheless be experienced, the contamination has to be washed off residue-free immediately upon occurrence by the originator with non-aggressive detergents. Particularly concrete and cement sludge, plaster and mortar are highly alkaline and lead to the glass being cauterised, (being tarnished). Contamination of this type is to be rinsed off immediately using plenty of water. Dusty and granular deposits may by no means be removed when dry, otherwise the glass surface would be scratched.
A minimization of contamination can be achieved by optimizing the course of construction and by protective measures, e.g. the application of protective foils in front of the windows.

3.1.2 Cleaning specifications for glass

When cleaning glass always work with plenty of clean water to avoid an abrasive effect caused by the dirt particles. The tools to be used are soft, clean sponges, cloths or rubber wipers. The cleaning effect may be supported by using neutral detergents or customary household glass cleanser. To clean grease or residues of caulk the use of ethyl alcohol is recommended.
Alkali brine, acids and agents containing fluoride may, as a rule, not be used. The use of sharp-edged, metal objects, i.e. blades or knives, may cause damage to the surfaces (scratches). Cleaning the glass surface with a glass scraper is impermissible. If damage is detected that has been caused by cleaning while carrying out the cleaning work, this work has to be interrupted immediately and the necessary information has to be obtained on how further damage can be avoided.

3.2 Paint and stain surfaces

3.2.1 In the course of construction

For paint and stain finishes the same applies as described under Point 3.1.1. Here again, any aggressive contamination is to be avoided. Particularly highly alkaline contamination may lead to an alkali burn of the surfaces, it is irreparable. Already the settling of construction dust (concrete, cement, plaster, mortar etc.) in connection with rain water forms an alkaline solution that corrodes the paint / stain. If such a contamination should be experienced cleansing with plenty of water should be taken in hand immediately.

In this connection the following cleaning recommendation: construction dust (concrete, cement, plaster, mortar etc.): must be removed immediately before the next rainfall, before cleaning the glass respectively. The dust should be suction-cleaned, then glass and paint/stain surfaces are cleaned with plenty of water (without detergents).

3.2.2 Maintenance of the finish

Upon completion of the construction phase the deposit of construction dust is no longer expected. Cleaning may be effected with plenty of clean water as described under Point 3.1.2 for glass.

After cleaning the painted surfaces the maintenance emulsion "Quick + Easy" should be applied 1 or 2 x annually. This applies ideally also during the construction phase. (Handling instructions see 4.5.1)

If damage to the surface has been ascertained this shall be corrected professionally immediately.
In this connection refer to our handling instructions in connection with refurbishment coats of paint/stain (Points 4.5.3 and 4.5.5).

3.3 Hardware

3.3.1 Cleaning the hardware

After the construction phase the hardware has to be cleaned as required. Possible contamination from construction has to be eliminated as this is often the cause behind sluggish operation. As is the case for the entire window element, the hardware may also only be cleaned using mild, neutral detergents in dissolved form. Preliminary cleaning by dust suction (vacuum cleaner) is recommended. Under no circumstances may aggressive detergents containing acid or scouring agents be used as these could corrode the corrosion protection of the hardware.
Should operable parts and locking points have to be cleaned these have to be greased or oiled after cleaning.

3.3.2 Maintenance of the hardware

To ensure that the free movement and perfect operability of the hardware is maintained, all the operable parts and the locking points have to undergo maintenance at regular intervals. Apart from setting and adjusting the hardware requires greasing and oiling exclusively with acid-free and non-resinous lubricants such as e.g. WD 40 (multi-operation oil).

Maintenance should be carried out at least once annually.

4. Maintenance Instructions

4.1 Introduction

High-quality wooden windows and doors are articles of daily use, their maintenance and utilisation safety and usability require regular maintenance and repairs.

Apart from regular cleaning and maintenance (refer to Point 3) we recommend annual maintenance of the windows (adjustment and lubricating the hardware, checking and possibly retouching the finish, checking the seals etc.).

Furthermore we recommend additional maintenance to the outdoor surfaces with maintenance emulsion Quick & Easy (in this connection refer to Point 4.5.1).

Our trained specialist employees would gladly deal with the maintenance of your windows.

4.2 Cleaning and Maintenance

The regular cleaning and maintenance is a prerequisite for maintaining the lifetime operability of these high-quality products. The exterior and interior surfaces, in the case of windows also the meeting stile areas, have to be cleaned. In this connection please use cleaning agents that do not corrode the materials (in this connection refer to Points 3.1.2 to 3.3.2).

4.3 Maintenance

All elements have to be checked at regular intervals for damage and deformation. This also includes the building joints and special components (e.g. sun protection equipment, screens, roll shutters, etc.).

The paint and stain finishes require particular attention. They have to be checked at regular intervals and damage of foreign influence or from weathering has to be touched up immediately.

Likewise security-relevant components require checking. They have to be checked at regular intervals for tight fitting and wear and tear. Operable parts have to be lubricated with suitable substances, see Point 3.3.2. in this connection.

This work should be carried out once annually.

4.4 Maintenance agreement

The windows and their components are subject to wear and tear, among others due to;

To allow you to rely on the perfect operability of the windows at all rimes, you should handover the annual maintenance to specialists. We gladly offer our maintenance agreement in this connection.

In our maintenance agreement the scope of services for the job is described in detail, e.g.:

After maintenance has been carried out you will receive a status report on your windows, We can also extend the warranty to 5 years in connection with our maintenance agreement.

• In preparation clean the windows with a neutral detergent (household cleaner, e.g. Mr. Clean). (Should dust contamination be high, first vacuum clean). Follow up by rinsing with plenty of water. Then allow the surfaces to dry.
• After drying remove the flaking paint with a grinder followed by sandpaper of 150 grit and dedust the surface (at best using a moistened cloth).
• Apply primer to the surfaces (only where the paint has been removed). A standard white window primer may be used.
• After drying slightly resand all the surfaces with sandpaper of 150 – 220 grit. Take care that no edges of the newly primed surfaces are ground off. Then remove the dust from the surface (best with a moist cloth).
• Fill v-grooves that may be open with a v-groove protection (e.g. Glasurit Elasto Fill).
• Apply 1x thin coat of paint.
Apply just enough paint to achieve a good finish without the formation of tears.
Allow paint to dry (in the case of water-based paint the drying time required is at least 4 hours, for solvent-based paints allow to dry overnight):
• Apply the second coat within two days (as described above).

Tools

• High-quality acrylic paintbrushes with split bristles (result in good coating cover)

Paints

• Please only use high-quality window paints! These may be water-based paints (e.g. Sikkens Rubbol BL Satin) or solvent-based paints (e.g. Sikkens Rubbol Ventura Satin). In the case of other coating systems, always first check compatibility with the undercoat.
