Teal timber products must be fully sealed on all four edges and two faces with a suitable sealant to protect doors and windows from moisture.

Teal can advise selection the most suitable timber finish to suit your individual home plan and needs. Professional paint suppliers and painters can also assist with advice.

Extend the life of the coating and appearance of your timber by following a regular maintenance and care program. Most timbers have a good reputation for accepting and holding most timber finishers for extended periods. Nevertheless, the normal life of a finish will be shortened by degradation and discolouration.

The causes of discolouration, though not in themselves a failure of the finish, often require remedial treatment.

Dirt is the most benign cause of discolouration and not an usually a problem. A periodic cleaning with a mild detergent solution will usually restore the surface finish. Mildew applies both to the fungus and to its staining effects on both the finish and the wood.

Mildew is a common cause of discolouration of paint, solid-colour stains and natural finishes. Restaining does not solve a mildew problem. When it is time to refinish, clean off the mildew with a commercial mildew remover then refinish with a coating containing an effective mildewcide.

Extractives bleed that discolour the finish is usually caused by moisture. Moisture problems must be eliminated to stop stains caused by extractives bleed. Mild staining is often washed away by rain over a period of weeks. In sheltered areas of the building where the stain persists, it may become darker with age and more difficult to remove. If washing with a mild detergent solution does not work a commercial product may be of benefit.

Iron staining may appear in two forms, namely, the reddish brown discolouration caused by rust and blue-black discolouration caused by the reaction of iron from nails and other metal objects with extractives from the timber. To prevent such stains use only hot-dipped galvanized, aluminium or stainless steel nails when fastening timber. Water stains often occur in combination with extractive bleed and mildew growth. These stains can be difficult to remove. Scrubbing the wood with an oxalic solution is sometimes effective.

Teal Timber Tannin Cleaner
Teal Windows have a superior cleaner specifically designed for the leeching and removal of tannin from timber. Tannin is the stain that exudes from unsealed timber. Teal Tannin Cleaner will remove the majority of tannin out of the timber. There is a slight possibility a small amount of tannin may still leech out at a later date under certain conditions. Teal Tannin Cleaner will aid in preventing leeching stains from running down walls or staining tiles etc. This is achieved by Teal Windows washing all components of joinery two or three times after sanding and then sanding lightly again. This process is a very time consuming. Tannin is not a concern in many projects but if it is a concern for you please don't hesitate to ask.

If you purchase this product separately from Teal Windows do not wash any products were leeching can run or splash on a porous product or item that may be susceptible to staining.
