Evaluate the Existing Paint System

Before beginning preparation, the existing coating must be inspected carefully to determine whether it is suitable for recoating.

If the existing coating is unstable or deteriorated, it should be removed before proceeding with a new paint system.

Cleaning the Surface

All previously painted surfaces must be cleaned thoroughly before sanding or further preparation. Wax, silicone, oil, and environmental contamination can cause adhesion failure or surface defects.

• Wash the surface using soap and water
• Remove wax or polish residues
• Wipe down using an approved solvent cleaner
• Use clean lint-free cloths when wiping surfaces

Cleaning should always be performed before sanding to prevent contaminants from being embedded into the coating surface.

Sanding Previously Painted Surfaces

Sanding removes surface gloss and creates the mechanical profile required for proper adhesion of primers and topcoats.

Final Surface Preparation

After sanding, the surface must be cleaned again before primer application.

• Remove sanding dust using clean compressed air
• Wipe down the surface with solvent cleaner
• Use lint-free wiping cloths
• Avoid touching prepared surfaces with bare hands

The prepared surface should appear evenly dull with no remaining gloss.

Priming Before Topcoat

Previously painted surfaces are typically primed before applying a finish coat to improve adhesion and create a smooth substrate for the topcoat system.
