Window frames treated with oil, wax, or in poor condition
The ClearComfort system relies on a strong adhesive bond between our double-sided tape and the window frame.

Wood with an oil or wax finish
An oil or wax finish does not provide a sufficiently adhesive surface, so some preparation is required. Lightly sand a 20mm strip where you will be placing the double-sided tape to remove all traces of oil or wax. The smooth raw timber should then provide a strong base for the double-sided tape.

Old and flaking paint
If your window frames are in poor condition, they will provide a less than ideal adhesive surface and are more likely to require maintenance in the coming years. We recommend standard maintenance such as sanding back and re-painting of the window frames and sills before applying the ClearComfort system. Allow several weeks drying time to ensure complete curing of the paint. Only then can you be confident of having a sufficiently adhesive surface.
