What it means
Adhesion begins before the topcoat. Steel, aluminium, plastic and existing coatings each require a different preparation strategy. The right primer and cleaning process are selected from the actual substrate, not from colour alone.
What to control
- Identify bare metal, plastic, existing paint or unknown substrates.
- Clean and abrade according to the product system.
- Select the correct primer or adhesion promoter.
- Confirm compatibility before applying a topcoat.
Technical note
Product performance, compatibility, drying, curing and regulatory information must be confirmed against the current TDS, SDS and label for the selected SKU.
