Water-Based Epoxy Floor Coatings for Industrial & Commercial Floors — Breathable, Low-VOC Protection
JOSME water-based epoxy floor coatings use water as the carrier instead of organic solvents, with VOC less than 50 g/L. They cure to a breathable, water-proof coating atop a two-part epoxy resin and water-compatible amine hardener. Shore D hardness 70–85, adhesion more than 2.5 MPa – ideal for tough industrial and commercial flooring.
What Makes This Floor Coating Different
Traditional solvent-based epoxy doesn’t work on damp concrete; the moisture trapped underneath builds up pressure and causes blistering, bulging and delamination, which costs big bucks to fix.
This is where at the chemical level JOSME’s water-based epoxy comes in. The cured film generates a micro-porous structure that allows the passage of water vapour but not of liquid water. This breathability helps safeguard the floor investment over the long term.
There are no organic solvents, therefore less fumes during application and no combustible ingredients on site, which is a practical safety benefit while working in enclosed or populated buildings.

Four-Layer Application System
The Water-Based Epoxy Floor Coatings has steady service life because of standard pretreatment and multi-layer construction.
Step 1 – Substrate Grinding: Mechanically polish concrete to open pores and remove loose layers, optimising fit of the coating.
Step 2 - Water Based Epoxy Primer: seals dust and pores, penetrates concrete to provide a secure foundation and improve bonding between layers.
Step 3 — Intermediate coat of water-based epoxy: It forms the main load-bearing basis, creating a consistent thickness and structural strength.
Step 4 – Water-Based Epoxy Topcoat: Final decorative and protective layer providing consistent colour and a smooth surface.
Key Performance Advantages
White emulsion gives consistent colour with no streaking. consistent Finishing Water
Chemical Resistance: Tested ASTM D1308, Alkali, Oils and Corrosives Resistant for Manufacturing and Food Workshops.
Abrasion & Scratch Resistance Shore D 70-85 ASTM D4060 Tested Structural integrity under friction and heavy stresses.
Safe & Low Odour - No solvent, no fire risk, no objectionable smell. Can be utilised inside or in crowded settings.
Anti-Blister Breathable Micro-porous Film avoids blistering and delamination on wet, new concrete.
Easy to Clean: Tools may be washed with water and soap. Cured surface can be disinfected repeatedly without damage.
Where These Coatings Are Used
Electronics Factories: The surface is smooth, without gaps, reduced dust buildup, appropriate to anti-static treatment.
Pharmaceutical & Medical Low odour Sterile flooring Resistance to disinfectants
Food & Beverage: Safe, minimal odour, organic acid resistant and hygienic washable.
underneath Parking & Basements: Breathable construction minimises delamination from moisture underneath.
Schools & Office Buildings: Clean, wear-resistant high-traffic floor.
Quality Control Process
JOSME has complete process quality management: inbound inspection, manufacturing supervision, batch testing.
Core testing : Pot life, drying time, adhesion (ASTM D3359), hardness (König), impact resistance (ASTM D2794).
Samples of each batch were held for colour, particle size and film consistency. Control of humidity for optimum film formation.
Customization and Supply Options
Flexible customisation to meet project specifications and procurement needs:
Colour matching and development to custom specs
Adjustment of particle size
Private Label Packaging
Formula Optimisation for Specific Substrates and Anti-Corrosion Requirements
Lead Times: Standard goods ship in 2-3 working days. Custom colour and private label orders ship in 7-15 working days. Large engineering orders support prior scheduling and reserved capacity.
Packaging
Export-grade reinforced packaging is adopted for all Water-Based Epoxy Floor Coatings, which can resist leakage, structural layering and mechanical damage during long-distance ocean transportation. Complete export certification documents can be provided upon customer request.
FAQ
Q1: Why do solvent epoxy floors blister, and how does water-based epoxy solve it?
A1: Solvent films are airtight. Trapped moisture vapour lifts coating. With water-based epoxy, vapours may escape via the micro-porous structure of the epoxy, thus the epoxy does not blister on wet concrete.
Q2: Suitable for pharmaceutical and electronic clean room?
A2: Yes. The smooth sealed surface minimises dust, can be re-disinfected several times and has stable chemical resistance suitable for cleanroom requirements.
Q3: Is it possible to build on moist concrete?
A3: Yeah. Water-based solution works for damp substrates where solvent-based products can't. Eliminate standing water before construction.
Q4:Why is the coating turning milky white?
A4: This is normal for water based epoxy emulsion prior to cure. As water evaporates and resin polymerises , the film becomes translucent or coloured without impacting performance .
Q5: Do I need to use a primer?
A5: Yes. Primer fills the pores, increases the bonding of the layers and stabilises the overall adhesion especially on porous concrete.
