Can I paint new galvanised weld mesh wire panels without cleaning first? No corrosion currently, I just want to change the colour

This product could be applied to prepared galvanised steel, however the colour will remain the same and essentially provide no added benefit. Please e-mail technical@rawlinspaints.com with further details of your requirements to allow us to help further.

I have a steel structure which is hot dipped galvanised. Now there are sections of the structure that have shown corrosion. Can I clean back the corrosion and coat the entire structure in galvafroid for a uniform final finish? Does galvafroid stick on to hot dipped galvanised metal?

Yes, this product can be used on galvanised steel. Assuming the galvanised steel is thoroughly cleaned and degreased as detailed in the technical datasheet, to ensure the removal of all oils, grease, mill scale and rusted areas, we'd firstly recommend preparing the galvanised areas with Teamac Mordant Solution (T Wash) , which increase the adhesive properties for you to overcoat with Fosroc Galvafroid.

I am looking to specify a coating for our steel doors. Our current spec is: 01. ALL SUBSTRATE METALS SHALL BE PREPARED TO SA 2.5 02. ALL COATING SHALL BE 3 PACK MARINE GRADE GLOSS COATING. 03. COLOUR: RAL BS4800 HOLLYBUSH 14 C 39 We have experienced issues with paint delaminating from the doors due to rusting of the substrate steel. can fosroc Galvafroid be used as a primer for 3 pack marine grade gloss coatings.

This product may be painted to improve durability and/or enhance appearance, but it should not be rubbed down to obtain a smooth surface for finishing paints. For general purposes a good oil bound or alkyd paint should be used. Fosroc Dekguard A Plus can be used to provide a decorative finish to Fosroc Galvafroid, with a 2 coat application recommended. Where any work is subject to corrosive and marine conditions a non-saponifiable finishing paint should be used such as Chlorinated Rubber. It is advisable to allow Fosroc Galvafroid to weather for at least 3 days prior to applying the finishing coat. Cellulose and bituminous paint are not generally suitable for over-painting Fosroc Galvafroid. Assuming the proposed 3 pack marine paint meets the above requirements, then Fosroc Galvafroid can be used as a Primer.

Good Afternoon If steel reinforcement bars are coated with galvafroid, can they be cast into concrete? Will this affect the bond of the concrete to the bar? Thanks

Yes, the bond to rebar is not based the metal but the ridges and deformations of the bar so as long as it’s not a smooth bar it will bond fine.

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
