Anti Static Flooring At The Ammunition Depot

An ammunition depot is a military storage facility for live ammunitions and explosives. The storage of live ammunition and explosives are inherently hazardous. There is the potential for accidents in the unloading, packing, and transfer of ammunition. Great care is taken in handling these dangerous explosives so as not to harm personnel or nearby ammunition. Generally, to avoid any kind of static on the floor, the installation of antistatic epoxy flooring is a must. We have almost completed the flooring work of 3240 sq m successfully. It was not just a project to us, but it was a great honor to be a part of the project of such high stature.

Actually, an Anti-static industrial floor inhibits the generation of electrostatic discharge, which is the pulse of static electricity that happens when a charged person or surface comes into contact with another object. The discharge may be visible as a spark or tiny blue bolt of electricity, although the majority of static electricity is not usually apparent.

Cleaning and maintenance is very important for an anti static epoxy flooring. There are a range of off the shelf anti-static cleaning products available, they work in exactly the same way as a standard floor cleaning chemical but include an anti-static additive that attracts moisture from the atmosphere that eliminates static build up. To further emphasis the importance of correct cleaning it is worth adding that many standard cleaning chemicals can actually increase the risk or propensity to static build up. It is highly recommended that you use a neutral PH cleaning chemical so that you do not add either a positively charged layer over the top of your floor surface.

Furthermore static will build up quicker on a dirty floor, the friction caused by the rubbing of the sole of a shoe and the dust and dirt on the floor will create static. A good and regular cleaning regime using the correct cleaning chemicals will ensure a static free floor. Moreover, right type of shoes is very important. The reason you build up static electricity usually comes from walking on an insulated surface with certain types of insulating shoes, especially when the weather / room humidity is very dry. We would strongly recommend that you avoid trainers or any shoes with rubber soles. Leather soles are good and for the best solution use either anti-static or even better ESD footwear. Providing the correct footwear is a far more cost effective solution that installing a full ESD flooring if you don’t need one!!!!

The method of installation of an anti static floor includes the following steps:

Surface Preparation

All Substrates should be dry (max. 5% moisture content), clean, sound and free of laitance. Surface grinders and shot blasting are used to prepare the surface; the surface should be properly cleaned and should be free from dust prior to application of primer.


It is imperative that the Primer-contents are thoroughly premixed prior to mixing together. The contents are mixed slowly using a slow speed drill and paddle for at least 4 minutes. Primer is then applied on the dry concrete surface @ 0.2 to 0.25Kg/per square meter by Brush/Roller.

Use of a screed sometimes is optional.

Laying of Copper Tape

A copper strip of required width and thickness is laid. The butter paper is firstly removed and the adhesive side of the copper strip is kept exposed. Stick the self-adhesive copper strip on to the clean primed substrate at a distance of 1 to 4 meter to each other, lengthwise and breadth wise.

At the periphery, near to the walls, stick the self-adhesive copper strip at a distance of 6 inches from the walls. At any one end in the room, copper strip should be extended out for connection of earthing.

Base Coat

It is a three component self leveling system which is natural black in color. Base coat should be applied after drying of the Primer (usually after 6 – 8 hrs. from application of primer).

Top Coat

Top Coat is a three component self leveling system. There is a wide range of colors available for that and Technical department should be contacted for choosing the best suited color for a particular surrounding. Top coat is applied just after the drying of base coat. A gap of at least 12 hrs should be maintained for application of topcoat.
