Does the zinc clad iv can be coated when previous coat is zinc clad ii, for repairs and welds?

An Organic Zinc ( Sherwin-Williams Zinc Clad IV 80% or Sherwin-Williams Zinc Clad IV 85% ) can be used to repair an Inorganic Zinc Silicate ( Sherwin-Williams Zinc Clad II EU ) when that Inorganic Zinc Silicate has been damaged back to bare steel. Just ensure, the bare steel is prepared correctly. Existing intact Inorganic Zinc Silicate is feathered back to a firm edge and that salt levels are of an acceptable level with minimum overlap of Organic onto Inorganic.

Hi we need to paint our steel frame with intumescent paint. The architect has specified the colour black, is this available?

Intumescent paints for steel generally come in white only and cannot be left as a finish, so the usual process would be to ensure the steelwork is prepared, primed (with a compatible primer), coated with the intumescent paint in white and then finished with a compatible topcoat in the colour and finish of your choice. To enable us to provide a more detailed specification for your project, please provide us with as much of the following information as possible; - Level of fire protection required (i.e. 30, 60, 90min, etc.) - Each steel section dimension (i.e. 254x146x37 UB) - Quantity and length of each section (or overall meterage for each section) - Orientation (horizontal or vertical) - Number of sides to be painted (all sides, 3 sides, 1 flange, etc.) - Environment (internal, external, car park, chemical exposure, etc.) - Application on site or in shop Alternatively you can just forward us drawings, fabrication/cutting lists and we'll extract the information from them but in that instance we'd need some guidance as to what to allow for i.e. all steels on first floor, etc.

ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour
