What is enamel paint?

Enamel paint is a high-gloss alkyd- or polyurethane-resin based paint with strong flow and film-forming properties that, when dry, gives a smooth, hard and washable surface visually resembling true vitreous enamel. Although not vitrified enamel, it shares the gloss, colour stability and durability.

Properties

A good enamel paint shows:

• High gloss (90+ gloss units) — mirror-like, striking
• Strong flow — brush marks disappear during drying
• High opacity — usually two thin coats suffice
• Good sanding and recoating
• Resistance to cleaning agents and regular wiping
• Long-term yellowing on classic alkyd; modern water-based versions exist

Types of enamel paint

Type	Base	Application
Alkyd enamel	Solvent	Classic wood and metal indoors and outdoors
Water-based enamel	Water	Indoor frames, lower-impact
Polyurethane enamel	2K system	High wear, floors, metal
Industrial enamel	Solvent	Machinery, steel beams, gates

Application

Enamel paint is mainly used on:

• Timber frames, doors and mouldings — interior and exterior
• Steel railings, balustrades, gates — after primer
• Radiators and heating pipes — heat-resistant variant
• Furniture — for high-quality finishes
• Decorative elements — for deep colour effect

How to apply

1. Sand the substrate — adhesion depends on key
2. Make dust-free — otherwise nibs show through
3. Apply primer — on metal or timber as required
4. Two thin coats — better than one thick coat
5. Good flow — use a fine lacquer brush or small roller
6. Dust-free room — during and shortly after application
7. Respect drying times — typically 6–24 hours between coats
