Epoxy and floor coating covers resin-based systems applied over concrete: garage floors, warehouse and factory slabs, car park decks, retail units, and increasingly residential spaces that want a seamless, easy-to-clean finish. The category also includes related systems like polyurethane (PU) coatings, self-leveling screeds, and anti-slip or chemical-resistant floors for industrial kitchens and workshops. We've listed 7 businesses in Petaling Jaya doing this kind of work.
What the job actually involves
A proper epoxy floor isn't just paint rolled onto concrete. It starts with surface prep: grinding or shot blasting to open up the concrete pores, moisture testing (especially important in Malaysia's humidity and on ground-floor slabs), and patching cracks or spalled areas. Then comes a primer coat, a body coat (sometimes with a decorative flake or quartz broadcast), and a topcoat for durability and UV stability. Skipping prep is the single biggest cause of failure: coatings that bubble, peel, or delaminate within months almost always trace back to a slab that wasn't ground or dried properly before coating.
What to check before you hire
- Ask what prep method they use (grinding vs. acid etching) and whether they do moisture testing on ground-level slabs.
- Get the system spec in writing: number of coats, coverage rate, cure time before foot and vehicle traffic.
- Check if they've done floors in a similar setting (residential garage vs. industrial warehouse vs. commercial retail have different demands for thickness and slip resistance).
- Ask about warranty terms and what would void them.
