    Question: 

    Can you use this over the top of old paint on metal external stairs

    questions Richard on 2023-08-30 08:35:22
    Question: 

    Im looking to use this on the inside of automotive panels and pillars as part of a restoration project. Eventually, i intend to prime the whole car in an epoxy primer, will this be compatible? If so, can you recommend an epoxy primer to use too?

    Answer from Rawlins’ Technical Team: 

    Assuming the panels are steel this product will be suitable to use as a Primer to be applied in accordance with the technical data sheet.

    This can be over coated with either Rust-Oleum CombiColor Original or Rust-Oleum 7500 Alkythane as the finishing coat.

    These products are both available to 4400+ RAL, BS & NCS Colours in a satin or gloss finish.

    The manufacturer doesn't recommend applying an Epoxy Primer over Rust-Oleum 769/780 Damp-Proof Rust Primer.

    questions 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.

    questions 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.

    questions 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.

    questions 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.

    questions 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.
