Teknos exterior Joinery Maintenance Guide 2015
Teknos factory applied coatings systems will give many years of life between re painting cycles, and simple steps such as wiping down the joinery finish to remove dirt and insects will help extend the decorative finish. This can be done at the same time as cleaning the glass. Good household maintenance also helps to extend repainting intervals. At least once a year:
The list below shows the typical maintenance products used to maintain factory finished joinery. These can be purchased direct from our service centres in Banbury, Livingston and Belfast. Payment is accepted by credit or debit card and orders placed before noon will normally be despatched the same day and delivered by courier within three working days. Typically 1 litre of primer or topcoat will cover a surface area of 8 - 10 square metres.
First and subsequent redecoration
If regular maintenance is delayed or some other damage has occurred, additional steps may be necessary to reinstate the finish to its initial condition. The notes below cover the most common problems, and further help is available from our Customer Service teams. Where minor flaking affects small areas of the topcoat surface but the timber substrate is not exposed: Abrade the damaged area with a fine grade abrasive paper to remove all unsound coating and feather out to leave a smooth surface. Clean down and wash the abraded area to remove dust, and allow to thoroughly dry. Apply a coat of Aquatop 2600 opaque or translucent topcoat in the appropriate shade, colour and gloss level to the damaged area. Allow to dry for four hours and then apply a second coat If the damaged area is widespread, lightly abrade the complete frame; repair the damaged area as described above; apply the second coat to the complete frame. Where moisture has penetrated joints, end grain, mitres or natural movement of the timber has opened shakes, treat as follows: Abrade the damaged area with a fine grade abrasive paper to remove all unsound coating and feather out to leave a smooth surface. Clean down and wash the abraded area to remove dust, and allow to thoroughly dry.
Resin occurs naturally in timber, in pockets within the wood or associated with knots. Some timber species are naturally more resinous than others , but the presence of resin is normally not detectable when joinery is manufactured. Resin exudation often occurs on southern elevations and on darker coloured joinery where the sun’s heat liquifies and mobilises the resin drawing it to the surface. Where resin has exuded through the coating: Although it may be unsightly, it is better not to remove fresh sticky resin. In practice, this can be very difficult, and its presence indicates that the exudation is still continuing. Remedial work is often best left until the first maintenance period, by which time the resin has normally fully crystallised. The best remedial treatment is to allow it to weather until it dries and oxidises, forming a white crystalline powder. The dried resin can then be removed with a stiff nylon or natural bristle brush, and any remaining residues washed off with a cloth. Water based coatings often allow the passage of resin to the surface without damaging the coating. If the finish is not damaged, by over-vigorous scrubbing during crystal removal, re-coating is often unnecessary, but otherwise an overall application of a finish coat restores the general appearance of the timber and maintains its protection.
Applying water based paints
The short drying time and reduced flow of water based paints requires a different technique to achieve a good finish. Following a few simple hints will produce excellent results. The quality of the brush is very important; a long haired synthetic brush will give the best results. Avoid short haired or worn

Exposure conditions vary significantly in the British Isles. South facing elevations, coastal sites, and sunny exposed locations will all reduce, to some extent, coating life to first maintenance. This note gives a guide to typical maintenance cycles on cladding, factory finished with Teknos exterior systems. The lifetimes quoted are intended to give a reasonable guide in average UK conditions. As a general rule, Teknos recommend more frequent preventative, rather than reactive, maintenance. This helps maintain decorative appearance while reducing the time and cost of individual maintenance cycles.
Design factors affecting service life and maintenance cycles
Good profile design is critical to long term cladding performance. In particular, sharp edges should be eliminated and all features designed to ensure fast,
