Picklex® 20 Frequently Asked Questions

What is Picklex® 20?

Picklex® 20 One Step Metal Preparation is a “Value Added Green Product” which is water based, ready to use andperform Multiple jobs in one step. Picklex® 20 completely removes light mill oil, cutting fluid, flash rust/white rust, provides a pre-treatment/conversion coating, seals the coating and stops the oxidation process, all in one simple step, resulting in a rust/contamination free surface. It completely prepares the metal surface (both ferrous & non-ferrous) for a very long-term indoor rust protection (in terms of years), welding and finishing, such as priming, liquid painting, electrostatic painting, powder coating etc.

What type of metals can be used?

Picklex® can be applied on any type of metal (ferrous & non-ferrous) such as carbon steel, stainless steel, galvanized steel, aluminum etc.

Is sanding or blasting needed to prepare new metal surface?

No. Sanding or blasting is not needed. Picklex 20 in one step completely prepares the new metal surface by cleaning, providing with pre-treatment/conversion coating & seal the coating, ready for welding & top coating without using any sanding, blasting or use of any other chemical.

How safe is Picklex® 20?

Picklex® is a water-based & water soluble product and is very safe and easy to use.

What kind of personal protection is needed while using the product?

Wear rubber gloves and safety eye glasses to protect your eyes.

How it is applied?

Brushing, Spraying, Dipping, Wiping etc.

Can it be applied on bare metal and also on metal surface with visible surface rust?

Yes, Picklex® 20 can be applied right on the bare metal surface with or without visible rust. Picklex® 20 is a pre-treatment/conversion coating which is used to provide very good bonding with the top coating and also provide much longer corrosion resistance (paint life) compared to the same paint job performed on the sanded or blasted metal surface.

How thick should be the coating?

Apply very less product on the metal surface. The coating should be just one extremely thin coating. It becomes a part of the metal surface with almost zero thickness. Any excess chemical on the metal surface becomes a residue which can affect bonding and corrosion resistance (Paint life).

What is the process?

Apply Picklex® 20 by spraying and/or brushing, after one minute wipe off or blow off the excess chemical completely down to the metal surface. Air dry or heat dry with a heat gun.

Is Rinsing involved?


Does the excess product on the metal surface have to be removed completely?

YES, otherwise there will be residue which will affect proper drying and bonding with the top coating

Can Welding be performed on the coating?

Yes. Welding can be performed over the coating after complete drying. The coating enhances the welding (does not cause hydrogen embrittlement). Also, no weld spatter forms (Anti-spatter)

Is sanding of the coating needed?

NO. Primer & paint will have excellent bonding without sanding.

Can Priming be performed on the coating?

Yes, except using Self Etching primer.

Can Painting be performed right over the coating?


What happens when Picklex® 20 over sprayed on paint?

Picklex® 20 will not damage paint. But leaving the chemical for a long time may dull the paint. Just wipe off the chemical with wet cloth.

Can Powder coating be done over Picklex® 20 coating?

Yes, powder coating can be performed over Picklex® 20 coating with excellent adhesion and corrosion resistance. However, to speed up the process in this case, rinsing can be performed to completely remove the excess Picklex® 20 from the metal surface and must be completely oven dried (cannot be air-dried) before powder coating.

For indoor application, is primer needed?

For indoor application, just painting over Picklex® 20 coating will provide years of paint life without using any primer.

Can Picklex® 20 be applied on metal surfaces which can get very hot during operation?

Yes. Picklex® 20 coating can withstand around 2000ºF. High temperature paint, ceramic coating can be used on this coating.

What is the shelf life of Picklex® 20?

More than10 years when stored indoors in cool and dry place.

What happens if Picklex® 20 freezes?

Just keep it in a warm place and it will come back to the original condition.

Sometimes a brownish color is noticed after drying of the coating?

It is a part of the chemical and it is not rust. The color of rust is orange, not brown. Do not have to remove, just prime over.

Is any other cleaner can be used with Picklex® 20?

Do not use any other chemical with Picklex® 20, because it can react and the coating performance can be harmed.

How long Picklex® 20 coating will provide rust protection indoor?

For several years depending on the location (near coastal area or not).

What happens if a lot of dust collects on the coating before top coating?

Just wipe of the dust with a damp cloth. Do not use any cleaner.

Can body fillers be applied over Picklex® 20 coating?

Yes, after light buffing. But it is better to put the body filler over primer.

Can Picklex® 20 de-rust or de-scale?

Yes, dipping a heavy rusted tool/part or hot rolled steel with mill scale for few hours in Picklex® 20 will de-rust, de-scale, pickle, condition the metal and provide a conversion/protective coating, all at the same time. Strain the bath to remove all rust/scale particles and re-use Picklex® 20 until consumed completely.

Does Picklex® 20 convert rust or heat scale?

Yes, Picklex® 20 completely converts 100% rust and heat scale (such as mill scale) to a conversion coating over which welding can be performed after complete drying (for hot rolled steel, the mill scale does not have to be removed for welding and the weld strength will still be higher compared to the welding performed after completely removing the mill scale as per AWS specification (American WeldingAssociation). Priming and/or painting can also be performed over converted rust or scale. Note: For heavy rusted steel, the lose rust on the surface should be removed completely by wire-brush before applying Picklex® 20.

How to clean the Picklex® 20 spill on floor?

Just wash the chemical with large amount of water. Unlike acid, Picklex® 20 does not etch the metal surface while removing the rust and therefore no heavy metal goes in the waste water (not a hazardous waste).

Is Picklex® 20 cost effective?

Yes, it is extremely cost effective. Picklex® 20 has a very large coverage (around 1600 sq. ft. per gallon) and need only one thin coat. So the product cost comes out to be few cents per sq.ft. with very less labor time. Also, it cuts down lot of conventional steps such as sanding, blasting, re-work etc., saving a lot of labor, time, cost and energy. On top of that, the very long shelf life of Picklex® 20 eliminates any waste. In fact, Picklex® 20 is a “Value Added Product”.

Overseas shipping?

Yes, Picklex® 20 is being shipped to overseas countries by Fed Ex air, DHL, UPS or Post Office (express international mail). Please contact by e-mail to find out the total charges with shipping cost.
