The Spray Bike Frame Builder's Carbon Primer 400ml is a specialist aerosol primer formulated for carbon fibre bicycle frames. Carbon fibre presents unique challenges for frame painting — its smooth, non-porous surface means standard primers struggle to bond without preparation. Frame Builder's Carbon Primer is designed to adhere directly to carbon without the need for acid washing or heat treatment, creating a stable foundation for any Spray Bike colour coat.

The low-pressure, non-drip formula allows precise application over the complex curves and joints of a carbon frame — whether you're working on a road frame, a track bike, or a carbon fork. Spray from 20cm or more for consistent, even coverage. Once cured, the primer provides the adhesion base that allows Spray Bike's acrylic colour coats to bond effectively to what is otherwise a notoriously difficult surface to paint.

Carbon Primer is a key component of the Spray Bike Frame Builder's system, sitting between surface preparation and the colour coat stage. After priming, apply your chosen colour from the BLB London, Vintage, Historic, Pop, Nightshade, Fluorescent, or Keirin Flake collections. Finish with Frame Builder's Transparent Finish to seal and protect against UV fading and moisture.
