The resilience and the strength of a bond created with Fastweld 10 are highly dependent upon the thorough pretreatment of the substrates being bonded. A quality degreasing agent such as trichloroethylene or acetone should be used to clean joint surfaces in order to eliminate any trace of grease, oil, or dirt. Please note that paint thinners, alcohol, or gasoline should never be used as a degreasing agent for Fastweld 10. Chemical etching and mechanical abrasion create the toughest and most durable joints. If mechanical abrasion is the method chosen, an additional degreasing treatment should follow.
Once thoroughly mixed, Fastweld 10 Adhesive should be applied with a spatula to pretreated joint surfaces after they have dried. Immediately after the material is applied, the components should be properly placed and clamped together.
