Spray.Bike Frame Builder's Metal Primer - 400ml
This modern hi-tech anti-corrosive primer is designed to be used on any bare metal bicycle frameset prior to painting. Its acrylic base and white color make it slightly easier to use on steel than the Frame Builder's Cold-Zinc.

  • White acrylic anti-corrosive primer
  • Ideal for aluminium, steel, stainless steel and titanium bicycle framesets
  • Provides a strong adhesion for Spray.Bike paints
  • Recommended number of coats: 1
  • Drying time: 20 minutes
  • Requires no post-application heat treatment
  • On steel frames, can be used as a more modern hi-tech alternative to the Frame Builder’s Cold-Zinc

    Using the Frame Builder's Metal Primer
    Our metal primer is an all-purpose white-colored acrylic product, containing some clever ingredients to make it corrosion resistant, thus preventing rust.
    It’s designed to be used on aluminium, steel, stainless steel or titanium framesets. 
    As it’s acrylic, it’s fairly straightforward to use. It is ‘wet’ though, so don’t get too close (spray distance: at least 20 cm) or it will dribble.
    Also, being acrylic, it’s sandable when dry – so any mistakes can be rubbed away.
    Its white colour is also handy as you can see where you’ve been! This makes it easier to use on steel than the Frame Builder’s Cold-Zinc, as painting a metallic grey primer onto grey metal can be a bit of a visual pain!
    Please note that this primer is only for the external painting of tubes – it’s quite thick so you don’t want any inside your frame.

    Spray.Bike Frame Builder's Cold-Zinc - 400ml
    Traditionally, steel bikes were zinc-dipped before being painted, the zinc creating a non-corrosive barrier to prevent rust and prolong the frame’s life. Our cold-zinc spray primer honours that tradition and provides unrivalled protection against corrosion on steel bike frames.

    • Product color: metallic grey
    • Spray distance: at least 20 cm
    • 95% galvanised zinc primer
    • Apply internally and externally to prime raw steel tubing before painting
    • Recommended number of coats: 1
    • Drying time: 30 minutes to 1 hour
    • On steel frames, can be used as a more historically accurate alternative to the Frame Builder’s Metal Primer

    Using the Frame Builder’s Cold-Zinc
    Our cold-zinc is 95% galvanised zinc dust with just 5% bonder. Its high purity allows it to act effectively both as a primer and as an anti-corrosive (anti-rust) coat. However, because you’re spraying almost pure liquid metal, it can be a bit tricky to use at first. 
    You need a spray distance of at least 20 cm. As with our colors, the ingredients in this can are in powder form – but they're suspended in liquid, which evaporates on leaving the can. So, you’re spraying zinc dust. Too far away and its adhesion is low. Too close and you get wet liquid zinc running everywhere. We recommend an initial trial on something plastic or metal that’s solid and curved to give you confidence before use. 
    Don’t over-apply. A single coat will work perfectly.
    Spraying a small amount (only a quick squirt) inside your seat tube is a good idea. You need to keep the can vertical though, so hold the frame up to do this.
    Although we state that this cold-zinc should only be used on raw steel, we've had successful results using it as a primer on chrome- and nickel-plating too.
    You do need to take care using this product as it is metal in dust form, which is not a safe thing to breathe in! Wearing a mask is therefore essential. 
    If you feel this is all a bit much, our Frame Builder's Metal Primer is a hi-tech alternative that is easier and safer to use (almost like using our paint). However, it's thick acrylic, so don’t use it internally or you’ll never get that seat post back!

    Spray.Bike Frame Builder's Carbon Primer - 400ml
    This clear primer is specifically designed for raw carbon fiber and resin composite bicycle framesets.

    • Product color: clear
    • Spray distance: at least 20 cm
    • Provides a strong adhesion for Spray.Bike paints
    • Recommended number of coats: 1
    • Drying time: 10-15 minutes
    • Requires no post-application heat treatment

    Using the Frame Builder’s Carbon Primer
    Raw carbon fibre, either as a composite or a weave, is notoriously difficult to paint onto. Our carbon primer is a clever ‘etch’ primer which dries with a rough external texture that’s so micro-thin you can’t feel or see it but which allows the paint to adhere to it. 
    Make sure you spray from at least 20 cm away. And don’t over-apply. A single coat will work perfectly.
    It’s slightly odd to use at first, but it’s worth it for the results. Initially it seems to run like water, but then it lies flat and settles. Because of this, we strongly recommend you try it first on something plastic or metal that’s solid and curved, so you can understand how it applies. A small amount of practice will really help before spraying it on your expensive carbon friend!
    If any dribbles are visible after drying, lightly sand them away.
    Also, as this primer is clear, you can leave unpainted parts showing the carbon if you want but still prime the whole bike.
