SprayBike Frame Builder’s Metal Primer – 400 ml


This modern hi-tech anti-corrosion primer is designed for use on any bare metal bicycle frame prior to painting. The acrylic base and white colour make it slightly easier to use on steel than Frame Builder’s Cold-Zinc.

  • Paint colour: white
  • Spraying distance: 20 cm minimum
  • White acrylic anti-corrosion primer
  • Ideal for bicycle frames made of aluminium, steel, stainless steel and titanium
  • Provides a strong adhesion for Spray.Bike paint
  • Recommended number of coats: 1
  • Drying time: 20 minutes
  • Requires no heat treatment after application
  • On steel frames, this primer can be used as a hi-tech alternative to Spray.Bike Frame Builder’s Cold-Zinc

Using the Metal Primer of Frame Builder


Spray.Bike metal primer is a multi-purpose, white acrylic product that contains a number of clever ingredients to make it corrosion resistant and thus prevent rust.
It is designed to be used on frames made of aluminium, steel, stainless steel or titanium.
Because the paint is acrylic-based, it is fairly easy to use. For this primer, maintain a spray distance of at least 20 cm, otherwise the paint will drip. As the paint is acrylic-based, errors can still be wiped away for some time, until the paint is permanently dry.
The white colour is useful, so that you can see where you have been! This makes it easier to use on steel than, for example, the Spray.Bike Cold-Zinc from the Frame Builder. This primer is grey and that can be difficult on a grey frame.

Spray.Bike Frame Builder’s Cold-Zinc – 400ml


Traditionally steel bikes were galvanised before they were painted, the zinc creating a non-corrosive barrier to prevent rust and extend the life of the frame. The Spray.Bike Cold-Zinc Primer respects this tradition and offers an unparalleled protection against corrosion on steel frames.

  • Paint colour: metallic grey
  • Spray distance: minimum 20 cm
  • 95% galvanised zinc primer
  • 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 Frame Builder’s Metal Primer

Using cold-zinc primer from Spray.Bike Frame Builder


This cold-zinc primer is 95% galvanised zinc dust with only 5% binder. This high purity allows it to work effectively both as a primer and as an anticorrosive (rust inhibitor) coat. However, because you are spraying almost pure liquid metal, it can be a little tricky to use at first.
You need a spraying distance of at least 20 cm. As with all Spray.Bike colour spray cans, the ingredients in this spray are in powder form – but they are suspended in liquid, which evaporates when you leave the can. So you spray zinc dust. Because of this, the right distance from the spray surface is very important. Too far away and the adhesion is low. Too close and you get liquid zinc everywhere. We recommend first spraying a test round on a piece of plastic or metal, so that you get the right stroke.
You only need to apply one layer. Keep the spray can vertical so that you maintain a good flow.
Although it is said that this cold-zinc primer should only be used on untreated steel, we have heard successful results about its use as a primer for chrome and nickel plating.
You do need to be careful with this product, as it is metal in dust form, which is not safe to breathe in! Wearing a mask is therefore essential.

SprayBike Frame Builder’s Carbon Primer – 400 ml


This carbon primer is especially designed for bicycle frames made of carbon, i.e. raw carbon fibre and resin composite.

  • Paint colour: clear
  • Spraying distance: minimum 20 cm
  • Provides a strong adhesion for Spray.Bike paint
  • Recommended number of layers: 1
  • Drying time: 10-15 minutes
  • Requires no heat treatment after application

Using Frame Builder’s Carbon Primer


Raw carbon fibre, either as a composite or a fabric, is difficult to paint on. Spray.Bike Carbon Primer is a clever ‘etch’ primer that dries with a rough external texture that is so thin you can’t feel or see it, but allows the paint to adhere to it.
Make sure you spray from at least 20 cm away. One coat is sufficient.
It is a little strange to use at first, but it is worth it for the results. Initially it seems to run like water, but then the layer settles and starts to adhere. Therefore, we strongly recommend you to try it first on a piece of plastic or metal to see how it behaves.
If any drips are visible after drying, lightly sand them away.

SprayBike Frame Builder Smoothing Putty – 400 ml


This thick cover-all putty is perfect for refurbishing frames. It covers small irregularities, such as scratches, rust damage and stickers.

  • Paint colour: grey
  • Spraying distance: minimum 20 cm
  • Especially for steel, aluminium and even carbon parts
  • Recommended minimum layer: one
  • Easy to sand
  • Requires no heat treatment after application

Using the Smoothing Putty from Spray.Bike Frame Builder


This thick cover-all putty is perfect for tarnished bike frames. It can be used to cover small spots, including scratches, rust damage and decals. Keep the can at least 20 cm away from the surface when spraying. The putty can easily be sanded dry. Recommended minimum layer: one.
Note: When using Frame Builder’s Cold-Zinc or Metal Primer, prime first and then apply this putty.

Using the Frame Builder’s Metal Plating


The paints in the Spray.Bike Metal Plating range contain a high metal content. For this reason, we strongly recommend using a mouth and nose mask when using these products.
If you are spraying on a raw surface, please use the appropriate primer first (depending on the frame, see above).
As with our other colours, the Metal Plating range can be sprayed directly onto existing paintwork. However, please note the spray distance (at least 20 cm), which is further away than the Spray.Bike solid colours. You can cover a complete frame and a fork with 1 spray can.
The paint dries hard with a light satin finish and will not rub off. You might want to use the Transparent Finish of the Frame Builder to protect the paint from weathering.

Spray.Bike Frame Builder’s Transparent Finish – Satin/Gloss – 400ml


Spray.Bike colours are matte. This transparent acrylic finish adds a satin or glossy topcoat.

  • Paint colour: clear
  • Spray distance: minimum 20 cm
  • Especially for steel, aluminium and carbon parts
  • Recommended minimum layer: one
  • One coat: satin / two or more coats: gloss
  • Drying time between layers: 2 hours / full cure: minimum 24 hours
  • Does not require any heat treatment after application

Spray.Bike Frame Builder’s Transparent Finish – Matte – 400ml


This transparent acrylic finish adds a matte topcoat. Ideal for use on Spray.Bike colours. Also ideal to convert existing gloss finishes to a matt finish.

  • Paint colour: clear (note: is glossy at first use but dries quickly to a matt finish)
  • Spraying distance: minimum 20 cm
  • Especially for steel, aluminium and carbon parts
  • Recommended minimum layer: one
  • Drying time between layers: 2 hours / full cure: minimum 24 hours
  • Does not require any heat treatment after application

Using the Spray.Bike Frame Builder’s Transparent Finish


There are two versions of the Transparent Finish. In the satin/gloss version, one coat gives a satin finish, two or more coats give a glossy finish. The matt version adds a matt topcoat and can be used on top of Spray.Bike colours to keep them matt, or on top of any glossy finish to make them matt. Note, with the matte version, the finish appears glossy at first, but don’t worry – it dries very quickly and then becomes matte on its own.
Make sure the undercoat is completely dry before you apply the finish. Shake the spray can well and hold the can at least 20 cm away from the surface, keeping your hand / arm moving at all times.
Recommended minimum layer: one.
Drying time between layers: 2 hours / full cure: minimum 24 hours.
