Bilt Hamber Etchweld Corrosion Protection Spray (500ml)

Bilt Hamber Etchweld

A single-component reactive primer with high anti-corrosion protection that provides exceptional adhesion to steel and non-ferrous surfaces. This product serves not only as a conventional primer for topcoats but also offers weldability, making it an ideal aid for body repairs. It helps protect joints and flanges even before assembly and increases the durability of subsequently applied coatings.

Bilt Hamber Etchweld is a high-performance anti-corrosion primer spray that creates a strong chemical bond with metal substrates. It is designed to provide reliable adhesion across a wide range of surfaces, including steel, aluminium and zinc-treated or galvanized sheets. With a formulation free of heavy metals and chromates, it offers a safer, modern alternative to traditional reactive primers with poor adhesion.

An outstanding feature of this product is the ability to weld directly over the applied coating. It allows welding by MIG, TIG, ARC or gas methods without causing porous welds, enabling thorough anti-corrosion protection of overlapped joints and internal seams before assembly. Additionally, it acts as an adhesion promoter for sealants, fillers and a wide range of topcoats or powder coatings.

The product is very easy to apply and air-dries quickly. After application it creates a stable base that extends the life of the entire paint system and prevents corrosion from spreading under the paint. It is a suitable choice for classic restorers, bodyshops and demanding DIYers who require protection of metal parts from moisture and aggressive environmental influences.

Main features

• Single-component reactive anti-corrosion primer spray with high adhesion to metals.
• Ensures adhesion to steel, aluminium and galvanized surfaces.
• Allows welding directly over the applied layer without creating porous welds.
• Serves as a base for sealants, fillers, topcoats and powder coatings.
• Contains no heavy metals or chromates.
• Dries quickly in air and is easy to apply.

How to use

• Thoroughly clean the surface of mechanical contaminants, rust and degrease.
• Shake the container for at least two minutes before use.
• Apply from a distance of approximately 25 cm from the surface.
• For normal painting apply an even coat and let it dry 30 to 45 minutes before applying the next layer.
• When used for welding apply two light coats at intervals of 7 to 10 minutes.
• Before welding allow solvents to completely evaporate – at 20 °C this takes about one hour and in cooler conditions up to three hours.
• After finishing work on hollow sections we recommend sealing seams with body seam sealer and treating internal areas with protective wax.
