EnviroShield Polyurethane (PU) Floorings

Almost all the industries in India and Bangladesh today have epoxy/PU floorings in their plant area in order to provide a seamless, joint-less aesthetic, chemical-resistant, hygienic, and dustfree atmosphere. A survey in the USA on epoxy/PU floorings has indicated that about 20% of the problems were due to the wrong selection of material/thickness, 60% due to the wrong application, and 20% due to the poor quality of the products. Hence it is important to divide the discussion into three parts:

Pre-installation of guidelines for the honorable customers and Engineers

Selection the Right Products :

Various authors have deliberated on which kind of material to choose for which applications. This is therefore not covered here. The major difference between epoxy and PU systems is that PU is more flexible and hence is more suitable in high-impact areas.

Selection the right thickness:

It is very important to arrive at the correct thickness of flooring to provide optimum service to the required traffic conditions. The higher the thickness, the higher the durability, and the higher will be the cost. Hence, it is pertinent to calculate the right thickness

Analysis the requirement :

This is the most important part of the process for the selection of right product as well as the right application methods. Obviously, a single product cannot meet all the requirements and hence the customer has to allot a priority for each requirement. Light duty flooring can be laid from 500 microns to 1 mm, medium duty at 1 mm to 2 mm and heavy duty varies from 3 mm to 5 mm. All the above parameters can be said to resist the following four broad categories:

Mechanical effects:

Static and dynamic loads, abrasion, impact, vibration, skidding, conductive, or antistatic etc.

Chemical effects:

Oil, grease, chemicals, soluble salts, cleaning agents, solvents

Environmental effects:

Thermal exposure such as heat or cold, UV, and other weather conditions, noise

Biological effects:

Bacterial impact.


Step of Work and Procedure of EnviroShield PU Flooring concrete flooring company in Bangladesh

Moisture Testing

Moisture in the concrete or rising moisture from subsoil has been the single most contributing factor for failure due to bubbles. Moisture doesn't just mean water droplets, it could include high humidity. Some coatings shouldn't be applied when humidity levels are high. More obvious sources of serious moisture are things like rising moisture through concrete pores, the higher moisture content in new concrete, standing water puddles on a concrete slab, or, even more likely, a damp or even saturated surface

Check for Oil/Grease

Generally coatings do not stick to greasy, oily, waxy surfaces. This includes many kinds of plastic surfaces. Oily surfaces can be tricky, just grinding the surface is often not good enough, as oil within the concrete is bound to rise to the surface before the primer has the chance to stick. Even on what seems like a non-greasy surface, any coatings will 'bead-up' leaving behind hollow, coating-less circles or voids.

Check for Dust, Salts etc

This is one of the neglected steps and can lead to disastrous consequences. Coatings may stick to the dust but not to the base floor and can lead to de-bonding. Salts and/or minerals either deposited out on the surface from the curing of fresh concrete or from the evaporation of seawater on concrete, or steel can quickly ruin a coating.

All the above pre-installation steps are very important activities that should not be ignored to ensure a long-lasting epoxy/PU flooring solution.

The thermal surface preparation is required for following


After the surface preparation, the second step is to ensure that the surface is primed properly. The application of priming is as important as that of surface preparation in ensuring the longevity of flooring and is most likely to be ignored by most of the contractors. As may already be known, concrete consists of micro-pores that typically do not allow penetration of fillerrich epoxy coatings. Hence, it is essential that the initial bonding is achieved by an epoxy primer that contains only resin and hardener and is of such viscosity so as to penetrate the pores of concrete thus creating a bond equivalent to that of spiked shoe on a soft floor. Thus, the concrete pores that are opened up by surface preparation get filled by a proper epoxy primer and increase the durability of the topping multi-fold. Depending on the porosity of the concrete, viscosity of the primer shall be properly chosen. primers will not agree with vitrified tiles, polished marble/granite etc., these call for specially formulated primers. Once the primer layer is cured, which typically can take 4 to 12 h, depending on temperature and humidity, screed underlay has to be applied. It is strongly advised that screed underlay is applied over primer not later than 24 h. Once the primer layer is hardened, the interphase bond between screed and primer can diminish. In case of delay in screed application, it is advisable to wipe the primed surface with solvents like Xylene, MIBK etc. When the total thickness of the floor topping exceeds 3 mm, it is preferable to do a 2 mm self-leveling screed underlay followed by 1 mm self-leveling topping instead of 3 mm topping together. Though this concept is being questioned by many, the argument in favor of doing a screed underlay has the following merits


Execution of topping is very similar to that of execution of self-leveling underlay except the fact that topping contains a forth component i.e. pigment. Pigment needs to be added to component A (resin part); mixed well and component B & C are to be added sequentially. Proper mixing machines need to be used to ensure homogeneity of the system and consequent development of desired properties. Do not allow mechanical movement for 48 h and chemical exposure for 7 days.

Post-installation practices


Epoxy / PU floorings have been found to give an excellent service in various industries such as pharmaceuticals, food, automobile/auto ancillaries, textile, electronic, and electrical industries, light engineering, chemical industries, etc. However, it is important to ensure that the execution and maintenance has been done as per various standard procedures.
