FERTAN PREWAX Pre-treatment Wax 500ml – Seam Sealing & Creeping Wax

Extremely penetrating special wax for pre-treating folds, sheet metal overlaps, and welds. Penetrates deeply and prepares the substrate for the final seal.

• Extreme creep capability (seam penetrating)
• Penetrates into the tightest sheet metal folds & welds
• Forms a very thin, stable protective film
• Optimal preparation for cavity wax / UBS
• Ideal after rust removal with FERTAN
• Also protects tightly overlapping sheets
• Includes 4mm probe
• Content: 500ml spray

PREWAX is a specially developed "pre-wax" with extremely low viscosity. Its task is to penetrate deep into areas that thicker final coatings cannot reach: hairline cracks, spot welds, and tight sheet metal folds. It ensures that even the "gap within the gap" is permanently protected from moisture.

It is ideally used after a component has been derusted with FERTAN, but *before* the thick final layer (e.g., UBS 240 underbody protection or cavity protection wax) is applied. PREWAX thus acts as a deep-acting primer in the wax system. Also suitable as a temporary protective film on exterior surfaces.

Areas of Application

• Pre-treatment of door seams and bonnet edges
• Penetration of spot welds
• First layer in sills and cavities
• Temporary protection of bare metal parts

Scope of Delivery

• 1 × FERTAN PREWAX Pre-treatment Wax Spray 500ml
• 1 × Spray probe (Ø 4 mm) for targeted application

Application Note

For folds and overlaps, spray directly into the gap from a short distance. For cavities, use the enclosed probe and pull it through slowly.
Important: Due to its extreme penetrating ability, excess material may escape from crevices – cover the floor! Excess can be easily removed with petrol. After flashing off, the final coating (cavity wax/UBS) can be applied.
