Care during installation

Before a full redecoration of the coating is necessary, it is very important to keep on top of any damaged areas. These must be repaired within a suitable timescale and cared for in the correct way. This document takes the property owner through the required care and maintenance of the factory applied finishes.

Installation damages

If the coated timber surfaces are damaged during installation and this has caused any breach of the coating such as scratches then it is necessary to re-coat these areas with some fresh product.

Any installation damage leading to opening of the joints, or damages to the glazing sealant must be rectified as soon as possible. Failure to do this promptly will lead to problems with the coating system.

Cut ends

Where cill ends are cut to fit a window, it is essential that the cut end is properly treated and coated prior to installation.

For non-durable timbers such as Scots Pine a suitable brush-applied preservative is necessary to treat any cut ends. A coat of Ankolux Base stain in the appropriate colour should be applied for translucent finishes. This is followed by Ankolux End grain sealer in clear and then two full layers of the Ankolux Translucent Top Coat in the appropriate colour and sheen level. For opaque finishes, Hydrolux End Grain Sealer should be applied to the bare cut end. Follow this with two coats of Anker Stuy 17-0535 primer. Finally, two coats of the appropriate opaque top coat ****** should be applied to finish off the cut end. Allow 3-4 hours drying between each coat.

Opening of joints

Differential movement between two pieces of timber at a joint can cause the joints to open up. Joints can also open when the joinery is put under certain stresses during transit and installation. Any open joints must be repaired promptly by filling any gaps and then repainting them with a suitable finish.

Fill any open joints with Anker Stuy v-joint filler. This must be allowed to dry for 2 hours before application of subsequent coatings. Drying is at 20ºC and 60% relative humidity. Please note the v-joint sealer is only dry enough to overcoat if the filled area has gone clear. If it remains white and milky do not attempt to overcoat.

To achieve the best match to the spray applied finish it is wise to apply the same top coat product as used in the factory. To make these spray finishes suitable for application by brush they must be modified. Anker Stuy provide an additive for this modification. The factory applied coating finish incorporating the additive can be obtained from your joinery supplier or alternatively contact us at [email protected]

Physical damage to the coating

Any surface damage caused by knocks and heavy abrasion of the coating can breach the protective envelope. This can allow moisture ingress and degradation of the timber surface by sunlight.

Sand the damaged area. Make sure any step between the damage and the rest of the sound coated surface is eased by sanding around the damaged area with a fine grade abrasive. Once this is achieved apply 16-0200 base stain in the appropriate shade to any bare timber for translucent coatings. Apply Hydrolux Primer/Mid coat 17-0535 to any bare timber for opaque finishes. Finally apply 2-3 coats of the relevant finish depending on whether or not a translucent or opaque finish is required. Allow 3-4 hours drying between coats. Drying is at 20ºC and 60% relative humidity. It is vital that a good quality, long haired, synthetic brush suitable for the application of water-borne finishes is used.
