Epoxy flooring in a Singapore home is a good decision on the right floor and a poor one on the wrong floor, and the difference is almost never the epoxy. It is the surface underneath, the room, the light and the preparation. This guide gives the honest answers homeowners ask before they call a contractor, with Singapore’s rules and September 2026 prices, so the quotation you eventually get can be read line by line.
Which home floors suit epoxy
Every Rayson floor system is specified for concrete or cement screed. That makes epoxy a natural fit for:
- Living areas and bedrooms once the old tiles are hacked out and the screed is levelled. Many HDB and condo renovations already hack the floor; epoxy is then one of the cheapest seamless finishes to lay on the new screed.
- Garages, store rooms and utility areas, where a hard, cleanable, seamless surface earns its keep.
- Car porches and covered driveways of landed homes, with an anti-slip broadcast and a UV-stable polyurethane topcoat.
- Shophouse, loft and studio floors on bare concrete, where the industrial look is the point.
Two rooms need more thought. A kitchen floor suits epoxy on screed, with a light anti-slip texture near the sink and hob. A toilet or bathroom floor is wet every day, so it needs a real slip rating, a sound waterproofing membrane beneath it, and an honest conversation about whether tiles are the safer choice.
The honest disadvantages
- Sunlight. Standard epoxy yellows and chalks under UV. Balconies, sunlit rooms and porches need a polyurethane topcoat such as UraForce SB72 or the water-based WB58 and WB60, which do not yellow.
- Slipperiness. Smooth gloss epoxy is slippery when wet or soapy. Fine aggregate broadcast between coats, or a textured topcoat, gives grip at some cost to easy mopping.
- Scratches and marks. Gloss and dark colours show grit scratches, dust and dragged-furniture marks. Satin or matt topcoats hide wear better.
- Repairs show. A tile is replaced; an epoxy patch is visible unless the whole area is recoated.
- Preparation and moisture. Epoxy bonds only to a clean, ground, dry slab. A damp screed or a skipped grind is the cause of nearly every peeling floor.
- Odour during application. The hardener smells on the day. Water-based epoxy and water-based polyurethane are the mildest, which is why they are the products specified for occupied buildings.
- Movement. No coating bridges a moving crack; the crack comes through.
Epoxy versus tiles
| Epoxy on a prepared screed | Tiles | |
|---|---|---|
| Look and feel | Seamless, no grout lines; gloss, satin or matt; warmer underfoot | Grout lines; harder and cooler underfoot |
| Cost, September 2026 | S$4–12 per sq ft supplied and applied | Supply and lay varies widely with the tile chosen |
| If the old floor must come out | Hacking and disposal S$3–8 per sq ft, levelling S$1–5 | The same hacking and levelling cost |
| Time on site | Two coating days plus preparation; walkable next morning | Several days of laying and grouting, plus curing |
| Wear | Gloss shows scratches; a worn topcoat can be recoated | Scratch-resistant; chips are replaced tile by tile |
| Wet rooms | Needs an anti-slip texture and a membrane beneath | The established choice; rating chosen from the tile |
| Repairs | Patches show; recoat the area | Replace the tile |
Compare the two on the same scope, including preparation, before comparing prices. A quotation that shows only the epoxy line on a floor that still needs hacking is not comparable with one that includes the hacking.
Is it slippery? Ask for the rating
Singapore measures the slip resistance of floor surfaces under SS 485:2022. BCA’s accessibility code requires slip-resistant floors on accessible routes, and NEA’s code of practice recommends an R10 rating for public toilet floors. For a home, that means one practical rule: do not accept a bare gloss epoxy in a room that gets wet. Ask the applicator for the wet slip rating of the finish, and for aggregate broadcast into the coat or a textured topcoat where the floor will see water.
Toilets and kitchens: over the tiles, or after hacking
Most homeowner demand is for a no-hacking overlay on the existing toilet tiles. HDB allows a new finish over one existing layer with adhesive, without a permit, if the total including adhesive stays within 13 mm and the floor traps are not disturbed. Epoxy is not named in HDB’s guidelines, so ask HDB before unlisted work. Rayson’s published systems are for concrete and cement screed, and none is specified for glazed tiles, so an overlay is a job for the applicator to assess: the tiles must be sound with no hollow spots, degreased, abraded and primed, the grout lines filled, and the falls to the drain kept. If the floor leaks to the flat below, no overlay fixes it; the membrane beneath needs rebuilding, which is covered under toilet and bathroom waterproofing in Singapore.
After hacking is the clean case. The tiles and bed come out under an HDB permit, the screed is checked for falls and levelled, the membrane is renewed where the room is wet, and the epoxy system goes onto a floor Rayson’s data sheets are written for.
HDB rules to plan around
| Rule | What it means for the job |
|---|---|
| Renovation permit | Hacking and re-laying floor finishes needs HDB’s permit, applied for by the contractor |
| Registered contractor | All renovation work in a flat, permit or not, must be done by a contractor on HDB’s Directory of Renovation Contractors |
| Noisy work hours | Hacking, tile cutting and heavy drilling: 9 am to 5 pm on weekdays only; never on weekends, public holidays or the eves of major holidays |
| Hacking duration | Removal of finishes may take no more than three consecutive days |
| Thickness | Floor finish and screed together may not exceed 50 mm; an adhesive overlay may not exceed 13 mm |
| New flats | Bathroom and toilet finishes cannot be replaced for three years from the block’s completion |
| Household shelter | No floor finishes laid with adhesive, and no second layer |
| Loading | No loading of the slab beyond 150 kg per m²; lightweight top-ups need a permit |
Condominiums add the management corporation’s own by-laws: written approval before works, a refundable deposit, and working hours that typically run weekdays 9 am to 5 pm and Saturday mornings. Landed homes have no HDB rules but the same noise limits from NEA apply to the neighbours’ benefit.
What it costs, September 2026
| Item | Published range | Source |
|---|---|---|
| Home epoxy on a prepared screed | S$4–12 per sq ft | SmartCalculator.sg, July 2026; CWP, April 2026 |
| Epoxy flake finish, garage or showroom | S$6–11 per sq ft | Terris, August 2026 |
| One HDB toilet floor, overlay, minimum-charge job | S$650–1,200 per toilet; walls about S$1,150 more | Advertised contractor prices, seen 26 September 2026 |
| Tile hacking and disposal | S$3–8 per sq ft | SmartCalculator.sg; Shiok Living, September 2026; Home Expo Asia, 2026 |
| Screed levelling | S$1–5 per sq ft | The same three |
A 4-room flat with about 700 sq ft of living, dining and bedroom floor runs S$2,800–8,400 for the epoxy once the floor is at screed, or roughly S$5,600–17,500 for a full hack-and-coat job. These are market ranges from the sources listed at the end, not Rayson quotations; the applicator prices the job from the floor as it is. The full table, including industrial systems, is in the epoxy flooring cost guide.
How long it takes, from the data sheets
- Roller-applied epoxy such as FloorGuard R50 or HydroShield WE40: a primer and two coats, usually two days on site, walkable the next morning.
- Self-levelling epoxy, LevelShield SL120: foot traffic in 18–24 hours, light traffic in 2–4 days, full cure in 5–7 days at Singapore temperatures, with a recoat window of 16 hours to one day at 30 °C that must be kept.
- Water-based polyurethane topcoat, UraForce WB60: surface dry in about six hours; UraForce WB52 is trafficable three hours after application.
Add hacking days if the tiles come out, and a levelling day before the primer. Furniture goes back on felt pads after the light-traffic time, and heavy pieces after full cure.
Cleaning and living with it
Sweep or vacuum grit, which is what scratches a gloss floor, and mop with a neutral cleaner. Avoid abrasive pads, strong solvents and acids. Put felt pads under furniture and lift rather than drag. A textured anti-slip floor is cleared with a soft brush rather than a mop. When a topcoat wears in the walkways after years of use, it can be recoated without removing the floor.
What Rayson supplies for homes
Rayson manufactures the systems in Singapore and publishes a technical data sheet for every product:
- HydroShield WE40, a low-odour water-based epoxy for occupied buildings, with a UraForce WB60 clear or UraForce WB58 coloured water-based polyurethane topcoat that does not yellow.
- LevelShield SL120 where a seamless, poured floor is wanted, solvent-free so it can be laid in an enclosed room.
- UraForce SB72 or WB52 as the finish where sunlight reaches, and an aggregate broadcast or GripSafe AP12 for porches and wet areas.
- PrimeBond E20 as the primer on dry or damp screed.
Two things are not in the range: a system for coating over glazed tiles without hacking, and metallic or decorative-art finishes. If either is the job you have in mind, say so when you enquire and the applicator will advise.
How to get it done
Send photos of the floor as it is now, the rooms and their sizes, whether the home is HDB, condo or landed, whether the tiles are staying or going, and when the work can happen. Rayson reviews the floor, names the system, and introduces an applicator in the Rayson network who inspects, quotes, installs and warrants the workmanship on their own quotation.
