Adhesion Promoters & Primers - FAQs

What is an adhesion promoter and when should I use it?

Adhesion Promoter is used after surface prep and before painting. It helps paint bond to hard-to-stick materials like synthetics, plastics, and vinyl, reducing the risk of peeling.

What is Sole Flex used for?

Sole Flex is a flexible primer designed for sneaker soles, plastics, rubber and TPU. It allows paint and coatings to bend with the sole during wear without cracking.

Can I use Sticky Icky Binder with adhesion products?

Yes! Sticky Icky can be added at 3–5% into Adhesion Promoter or Sole Flex to increase durability, wear resistance, and chemical resistance for extreme-performance customs.

Do I need adhesion products for leather sneakers?

Leather typically does not require adhesion promoter when properly prepped, but it is highly recommended for synthetic panels, plastics, and soles to ensure long-lasting results.
