To improve adhesion (if required) to non-porous surfaces, prime with Sika® Aktivator 205.

Glass Degrease with alcohol or MEK
Aluminium, light alloys and stainless steel Degrease with alcohol or MEK
Other Metals Lightly abrade then degrease as above
Wood Lightly abrade surface then remove dust
Plastics Degrease using an agent recommended by plastics manufacturer
Concrete and other alkaline surfaces Brush and remove dust
