What is Epifanes Multicover and why choose it?
Epifanes Multicover is a universal, two-component epoxy primer designed for protective priming, bonding, filling and repair on a wide range of substrates. It offers quick chemical drying, excellent adhesion even at lower temperatures and outstanding anticorrosive performance on steel and other metals. Suitable for use above and below the waterline, it can be overcoated with both one-component and two-component paint systems, making it a flexible choice for new builds and maintenance work.

Application recommendations
- Ensure the surface is clean, dry, degreased and free from rust and other contamination.
- Remove salt and other water-soluble contamination by high-pressure fresh water hosing.
- Degrease with Epifanes Cleaning Solvent or another suitable degreaser; then sand the surface with P60–80.
- Do not apply wet-on-wet. Avoid excessively thick wet films to prevent sagging and drying problems.
- Avoid application in direct sunlight or strong wind to prevent too rapid solvent evaporation and reduced flow.
- Ensure the temperature of paint, object and surroundings do not differ significantly.
