Why should customers use WOMA’s waterjet-technology ? Because WOMA’s technology offers distinct advantages over other methods for surface preparation.

Here are ten reasons you can not run away from:

WOMA’s waterjetting significantly reduces the amount of deposit. Compared to grit blasting, up to 98 percent less solid waste material needs to be considered. WOMA’s customers save large amounts in disposal costs.

WOMA’s waterjetting significantly reduces the time required for cleanup because no grit needs to be collected and removed at the end of the job. WOMA’s customers save hundreds of hours of time and labor.

WOMA’s waterjetting is dust-free, allowing different trades, to work side by side. Moreover, dust-sensitive areas can be maintained while the waterjetting is carried out. WOMA’s customers save expensive time in drydocks.

WOMA’s waterjetting does not require wrapping or unwrapping of vessels. WOMA’s customers save large amounts of time, labor and material costs related to wrapping and unwrapping a vessel.

WOMA’s waterjetting generates very low impact forces on surfaces; working almost vibration-free. No substrate material will be removed. WOMA’s customers avoid damage on their structures.

WOMA’s waterjetting is used in rainy or windy environment. WOMA’s customers are not dependent on weather conditions and can readily schedule work with a high reliability.

WOMA’s waterjetting guarantees the highest possible cleanliness level among all surface preparation methods. The remaining level of salt, chloride and other elements is minimized. There is no embedded grit as found after grit blasting being a source for new corrosion. WOMA’s customers therefore offer an excellent surface to the painter with minimal risk of osmotic blistering.

WOMA’s waterjetting ensures excellent adhesion conditions between substrate and coating even if flash rust is present. WOMA’s customers guarantee limits set by regulatory bodies (such as 3.5 N/mm² required by the U.S. Navy).

WOMA’s waterjetting exposes the original profile. In contrast, grit blasting reduces the original profile height due to particle impact. WOMA’s customers offer an excellent surface profile to the painter giving a good mechanical bond between substrate and coating.

WOMA’s waterjetting operates emission-free in closed loop systems. Sealed tools connected to vacuum and water treatment systems prevent any exposure to paint particle dust, fume or water mist. WOMA’s customers contribute to a safe and clean environment.

WOMA’s Waterjetting Guarantees
Highest Sureface Quality

No Embedded Grit - Grit blasting embeds particles in the substrate which drastically reduces the adhesion of the applied coating to the surface.

No Profile Reduction - Grit blasting reduces the initial roughness obtained after the first grit blasting job.

Excellent Pull-Off Strenght - WOMA’s waterjetting produces excellent adhesion conditions, even if flush rusting appears.

No Microscopic Impurities - Grit blasting produces non-visible residue (dark appearing areas) on the substrate surface generating areas of subsequent coating failure.

Minimal Residues - WOMA’s waterjetting most reliably removes any residues (especially salts) from the substrates and, therefore, minimises the probability of osmotic blistering.

WOMA’s Waterjetting Guarantees Higher Efficiency and Lower Cost

Reduced Drydock Time - Dramatic savings in time since wrapping, unwrapping and cleanup time are minimized or eliminated.

Reduction in Amaount of Solid Disposal - Dramatic reduction in solid waste.
