A container is painted to match company colours, protect it from rust or improve its appearance when placed in a visible location. This page explains the preparation, the right paint system and how long the coating lasts outdoors \u2013 with a real before\/after from our workshop.<\/p>\n

Preparation \u2013 the decisive step<\/h2>\n

80 % of the result comes from the preparation. The process:<\/p>\n

    \n
  1. Cleaning and degreasing<\/strong> \u2013 salt, oil and dirt must be removed completely, otherwise the paint will not hold.<\/li>\n
  2. Removing flash rust and loose old paint<\/strong> \u2013 sanding, brushing or blasting down to a sound substrate.<\/li>\n
  3. Scuff sanding<\/strong> \u2013 even intact old paint is roughened so the new paint adheres.<\/li>\n
  4. Repairing dents and rust spots<\/strong> \u2013 rusted-through areas are cut out and re-welded.<\/li>\n
  5. Masking<\/strong> \u2013 seals, fittings, type plates and the CSC plate.<\/li>\n<\/ol>\n

    Do not skip the primer<\/h3>\n

    On bare sanded or blasted steel, a primer<\/strong> must follow promptly \u2013 bare steel develops flash rust within a few hours, especially in damp weather. The primer creates adhesion to the substrate and provides the actual corrosion protection; the topcoat provides colour and UV resistance. If you apply the topcoat directly over the old paint, you save one step and pay for it later with flaking in exactly those places where the substrate was not sound.<\/p>\n

    The right paint system<\/h2>\n
    \n\n\n\n\n\n\n
    System<\/th>\nBuild-up<\/th>\nOutdoor durability<\/th>\nUse<\/th>\n<\/tr>\n<\/thead>\n
    2K epoxy primer + 2K PU topcoat<\/td>\nPrimer + topcoat, each 2-component<\/td>\nmany years<\/td>\nSpecialist company, paint booth \u2013 for a durable, presentable coating<\/td>\n<\/tr>\n

    For a container that will stand in a visible location for years, the 2K system is worthwhile. For a quick refresh or touch-up, 1K is often enough.<\/p>\n

    Application: spraying or roller?<\/h2>\n

    Airless spraying<\/strong> gives the most even result on large surfaces and reaches into the corrugations. Roller and brush<\/strong> are the right choice for touch-ups, small areas and edges. In practice, the two are often combined: spray the surface, then finish the details by hand.<\/p>\n

    RAL colour and coverage<\/h2>\n

    Any RAL colour is possible. Dark and strong shades (e.g. RAL 3000 Flame Red, RAL 5010 Gentian Blue) need more coats for full coverage than light greys. For an exact company colour, give us the RAL value or a sample.<\/p>\n

    Interior painting and floor coating<\/h2>\n

    Different requirements apply inside: here the focus is less on UV resistance than on brightness, ease of cleaning and \u2013 in food or technical areas \u2013 an abrasion-resistant, low-dust surface. A light-coloured 2K coating on the walls and ceiling is common and noticeably brightens the interior. The Floor<\/strong> made of film-faced plywood or bamboo plywood is treated with insecticides at the factory; if the container becomes a living or working space, the floor is either sealed or replaced entirely. An epoxy floor coating makes the surface suitable for vehicle traffic and easy to clean, but requires a dry, sanded substrate.<\/p>\n

    How much does painting a container cost?<\/h2>\n

    The price depends on the size (20 or 40 ft), the condition (how much preparation is needed), the colour (number of coats) and whether the inside and outside are painted. We will give you the price in our quote.<\/p>\n

    Have it painted by a specialist company<\/h2>\n

    Coin Container prepares the container mechanically (sanding, blasting), repairs rust spots and paints with a 2K system \u2013 including conversion in the same job if desired. A real-world example is the repainting of a 20 ft HC Open Side in RAL 7016. More on this: Container conversion and modification<\/a> and the case study Repainting in RAL 7016<\/a>.<\/p>\n

    Frequently asked questions<\/h2>\n

    How do I prepare a container for painting?<\/strong>
    \nClean and degrease, remove surface rust and loose old paint, sand intact old paint, repair dents and rust spots, and mask off seals, fittings, nameplates and the CSC plate. Around 80 % of the result is determined by the preparation.<\/p>\n

    Do I need a primer?<\/strong>
    \nYes. Bare steel develops surface rust within a few hours. The primer provides adhesion and corrosion protection, while the topcoat provides colour and UV resistance.<\/p>\n

    1K or 2K paint?<\/strong>
    \nFor a container that will stand in a visible location for years, the 2K system is worthwhile. For a quick refresh or touch-up, 1K is often enough.<\/p>\n
