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

Colour reproduction of the Products on the Site is limited by the technology used to deliver web pages and by the colour representation of Customer’s own monitor and computer set-up. We have made every effort to display as accurately as possible the colours of our Products but we cannot guarantee that the colour shown on Customer’s monitor’s display will accurately reflect the colour of the Product on delivery. We recommend that Customer first purchases the smallest Product available or access an industry standard colour chart in person (and not digitally) to ensure that the colour is acceptable for its purposes.

Surface Preparation

Apply only on a clean and dry surface with a temperature above the dew point to avoid condensation. In confined spaces, provide adequate ventilation during application and drying.

Steel (Blast Cleaned):

Blast clean to ISO 8501-1 SA 2.5 with a blast profile of maximum 40 µm Rz

Steel / Cast Iron:

Machine sand with P80-120 discs and degrease

Galvanised Steel and Phosphated Steel:

Abrade with SCOTCHBRITE® and degrease

Aluminium / Light Alloys:

Machine sand with P240-320 discs and degrease

GRP:

Machine sand with P240 discs and degrease

Painted Surfaces and Fillers:

Mixing

Thoroughly mix paint before activating and check colour before use
The speed of drying can be increased with use of 1-490 Thinner, or 6-550 Accelerator (added at 1-2%) but these can reduce the final gloss and shorten the pot life
Use of 1-490 Thinner AND 6-550 together is not recommended
Use of 1-490 Thinner or 6-550 when applied directly to aluminium is not advised

Mixing Ratio:

Selemix 7-534/7-535 2K Polyurethane Direct Topcoat Economy
- 4 parts base : 1 part hardener

Please Note: Refer to the Product Data Sheet for detailed information regarding mixing ratios for the relevant binder/base and hardener/activator used.

Mixing ratios between the Standard, High Solids and Economy versions of this product vary due to the different hardeners used.
