Surface preparation
Correct surface preparation is the key to successful bonding. In many instances, all that is required, with the Sikaflex® Marine Product Line, is a simple cleaning operation, but where there are weak or contaminated surfaces, more extensive preparation is needed to ensure a perfect bond. Typical problem areas include dust, dirt, grease, fat, oil, rust, flaking paint, etc.
The actual pretreatment selected will depend on the type of substrate (metal, plastic, paint, wood, etc.), the operating conditions in service, the degree of surface deterioration and the practicalities of any particular installation.
