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

Application Notes

Read the product label before use
Following dilution application can be either with a low-pressure pneumatic sprayer (course spray) or by using a watering can with a rose attachment
For small items such as gravestones etc, N-Virol Algae & Lichen Killer solution may be applied by a brush provided the solution is flooded generously into inscriptions and other cavities
Always direct the spray away from the body; do not spray directly overhead
Some species of lichen are resistant to treatment due to their impervious surface
To optimise the effect of N-Virol Algae & Lichen Killer solution, it is advisable to abrade the face of such growths prior to treatment. (E.g. stiff brush)
Once existing organic growth has been killed by an initial application (2-7 days) the treated surface will not need to be washed after the application of the product. However, in cases of severe contamination, this dead material should be removed using a stiff brush
