Dong Nai is a rare cluster in which four sub-areas within one cluster set four almost entirely different floor problems: electronics and precision engineering in Bien Hoa, heavy industry and chemicals in Nhon Trach, high technology and air-cargo logistics in Long Thanh, and traditional textiles and footwear along National Highway 1A. The right question for this cluster is therefore not “which epoxy floor is best”, but “which zone of the plant, which industry, and is the slab new or old?”
A note on place names: the former province names used in this article are geographic cluster names only, not current administrative units. Since the merger effective 01/07/2025, the new Dong Nai comprises the former Dong Nai and Binh Phuoc; the new Ho Chi Minh City comprises the former Ho Chi Minh City, Binh Duong and Ba Ria – Vung Tau; the new Tay Ninh comprises the former Tay Ninh and Long An; the new Dong Thap comprises the former Dong Thap and Tien Giang; the new Vinh Long comprises the former Vinh Long, Ben Tre and Tra Vinh; and the new Can Tho comprises the former Can Tho, Soc Trang and Hau Giang. The names Bien Hoa, Nhon Trach and Long Thanh in this article are familiar geographic names used to identify sub-areas, not names of new administrative units.
Four sub-areas, four floor problems
Bien Hoa, with Amata and Bien Hoa 2, concentrates electronics and precision engineering together with mixed industry. Floors here need to be flat, seamless and low-dust, similar to the requirements of a high-tech plant. Nhon Trach is the heavy end of the cluster: heavy industry, chemicals, engineering, building materials and specialist dyed textiles. Floors here must allow for chemical resistance and wet areas, and cannot share the same answer as an electronics floor. Long Thanh, with Long Duc and Loc An – Binh Son, is linked to the airport and logistics: high technology near the airport and warehousing needing heavy loads and high vehicle frequency. Trang Bom, Ho Nai and Song May along National Highway 1A are the traditional end, with textiles, footwear, wood and food, where floors need abrasion resistance and easy cleaning more than absolute flatness.
Floors for new plants: getting it right from a new concrete slab
Dong Nai is a cluster where demand for new floors predominates, linked to the wave of new plant construction around Long Thanh. For a new concrete slab, three steps must never be skipped: waiting for the concrete to reach sufficient age, measuring substrate moisture and choosing a suitable primer before coating. Coating new concrete that is still damp is a common cause of later blistering, even when the coating initially looks perfect. Floor coating is the last item in a plant construction programme, so the flooring schedule needs to be coordinated with the overall handover schedule — without delaying the overall programme, and without being forced to coat before the slab is ready.
For general production areas of a new plant, the RollCoat roller-applied system suits light to medium loads, while areas needing absolute flatness and a seamless surface should consider the LevelFlow self-levelling system. Where an area has an anti-static requirement, the direction is the StatGuard system, but only in exactly the zones that require it and following the investor’s standard.
Chemical-resistant floors for the heavy Nhon Trach cluster
Chemical and heavy-industry zones should be classified by exposure level before a system is chosen: zones with only light, occasional contact; zones with frequent contact; and zones at risk of leaks and chemical ponding. Each level points to a different system direction, with leak zones needing a specialist chemical-resistant system such as novolac or vinyl ester. This article only sets out the direction; which chemicals a specific system resists, at what concentration and for how long, must be checked against the manufacturer’s chemical resistance table and the actual survey results. See also the chemical floor framework in Epoxy Flooring for Chemical Plants: Acid and Alkali Resistance. No single epoxy system should be assumed to resist every chemical.
Dyeing and textile floors: moisture, bleaching chemicals and wet zones
Dyeing textiles combine a difficult set of conditions: a damp substrate, bleaching chemicals, wastewater and slippery wet zones. Floors here need moisture resistance, a suitable level of chemical resistance and anti-slip wet zones, plus easy cleaning so dye and residue do not build up. Measuring substrate moisture and providing a moisture barrier is a mandatory step, because moisture vapour from the substrate is a leading cause of blistering. For areas in operation that are sensitive to odour, the water-based AquaBase system is worth considering.
Airport and port logistics warehouse floors: heavy loads, lane markings, anti-slip
Warehouses linked to Long Thanh Airport and the port corridor need floors that carry heavy loads, high forklift frequency, marked lanes and anti-slip traffic routes and turning points. Unlike production floors, logistics warehouse floors wear in concentrated patterns along fixed vehicle routes, so acceptance should include load and turning tests on those very routes, not just a general surface check. See also the load-bearing floor framework in Epoxy Flooring for Forklift and Heavy Truck Floors. The construction schedule for a new warehouse also needs to fit the racking installation schedule and the first goods-in date, avoiding a situation where the floor has to carry full loads before it has cured sufficiently.
Frequently asked questions
Does a new plant need its substrate moisture measured before coating?
Yes. Coating new concrete that is still damp very easily blisters later. Measuring moisture, waiting for the concrete to reach sufficient age and choosing a suitable primer are three mandatory steps before coating, however tight the handover schedule is.
Does a chemical-resistant floor resist every chemical?
No. Chemical resistance depends on the individual chemical, its concentration, the contact time and the specific system. Leak zones need a specialist system and must be checked against the manufacturer’s chemical resistance table before the material is finalised.
How does an airport logistics warehouse differ from an ordinary warehouse?
Heavier loads, higher vehicle frequency and wear concentrated along fixed vehicle routes. An airport logistics warehouse floor therefore needs to emphasise load testing on the actual vehicle routes, anti-slip surfaces and clearly marked lanes.
What information should I send to receive advice?
Whether the plant is new or old, the industry, the area of each zone, any chemicals in contact with the floor, and the type and frequency of vehicles running on it. That is enough to point towards a system matched to each zone’s function before a survey and a specific quotation.
Is your plant new or old, which industry, and how large is it? Send the details to receive advice on a flooring system matched to each zone’s function via the quotation page or the contact page (hotline/Zalo 0899355489, WeChat wxid_95o54joujyrr12).
