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]

Send us your question

Natalie on 2023-04-30 14:43:20	Question: Is this primer and the Rust-Oleum 7500 Alkythane topcoat appropriate for use on Cast Iron? Thanks
	Answer from Rawlins’ Technical Team: Yes assuming the cast iron is bare, clean, dry, sound and free from rust or corrosion.

Cindy on 2023-03-06 16:01:14	Question: Can I paint acrylics over this primer?
	Answer from Rawlins’ Technical Team: The recommended topcoat for this primer is Rust-Oleum 7500 Alkythane. If you choose to use any other type of paint we would recommend to test on a small area for compatibility and adhesion prior to full application.

Nigel Sykes on 2022-12-08 07:20:15	Question: Hello, Is the 769/780 suitable for use when repainting the inside of a steel boat hull? This will be in January/February and although de-rusted as far as possible will probably still be damp and no doubt cold! Also, after it has cured can it be over coated with a two pack epoxy type paint… this type of top coat would be preferred to protect against oil, fuel and other chemical spills Thank you nin anticipation, Nigel.
	Answer from Rawlins’ Technical Team: Unfortunately no this product would not be suitable for this application. Assuming application will take place when the substrate temperature is above 5°C and the relative humidity is less than 80% with the temperature 3 degrees above the dew point so no condensation forms you can consider the two pack option below. All rust and corrosion must be removed, the area should be clean, dry, sound and prepared as detailed in the technical data sheet then Teamac High Performance 2 Pack Zinc Phosphate Primer applied followed by two coats of Teamac High Performance Polyurethane Topcoat. This is available in many RAL, NCS or BS colours in a gloss finish.

Gabriel on 2022-02-17 14:43:02	Question: Hello! Is it possible to paint over this primer with Rust-Oleum High temperature resistant paint (1078)? Thank you!
	Answer from Rawlins’ Technical Team: Assuming the substrate will be exposed to dry heat, no this primer would not be suitable for this application. Rust-Oleum Heat Resistant Paint 750°C is self priming for many substrates.

Mark harris on 2021-03-15 12:43:25	Question: Can you use any brand / type of thinners with Rust-Oleum 769/780 Damp-Proof Rust Primer? Many thanks Mark.
	Answer from Rawlins’ Technical Team: We would recommend using the Rust-Oleum thinners as listed on the technical data sheet.
