Epoxy flooring for HDB and condo toilets.

HDB allows a new floor finish to be laid over one existing layer with adhesive, without a permit, if the total thickness 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.

A smooth gloss epoxy is slippery when wet or soapy, which is why it is not the finish for a bare toilet floor. Broadcasting fine aggregate between coats or using a textured topcoat gives grip at some cost to easy cleaning. Singapore measures slip resistance under SS 485:2022, where a wet pendulum test gives a class from P0 to P5, and NEA's code of practice recommends an R10 rating for public toilet floors. Ask the applicator for the wet slip rating of the finish, not just the words anti-slip; no rating follows from a product name.

No. An epoxy or flake overlay seals the surface and the grout lines, which is why it stops water sitting in the grout, but it is not a waterproofing membrane. It can crack at wall junctions and at the drain, and it cannot stop water already in the slab or the pipes. A toilet that leaks to the flat below needs the membrane beneath the screed and tiles rebuilt; see toilet and bathroom waterproofing.

The homes guide's timings: on a prepared screed, a roller-applied epoxy is two coats over a primer, usually two days on site, walkable the next morning. A toilet floor then stays dry until the topcoat has cured fully per its data sheet before it takes standing water and heavy items. Get the return-to-use day and the first-shower day in writing from the applicator before the work is booked; do not assume same-day use.

Standard epoxy yellows and chalks in sunlight, and Rayson's product data says the same of HydroShield WE40. A toilet with a window, or any sunlit room, therefore takes a non-yellowing aliphatic polyurethane topcoat: water-based UraForce WB60 (clear) or WB58 (coloured) do not yellow and are low-odour, which suits an occupied home.

Many homeowners have the floor carried up the walls to about shoulder height with a coved skirting at the junction, so there is no grout line for water to sit in. The cost guide's figures put walls at about S$1,150 more per toilet, and the detailing at the coved skirting and the drain decides the price more than the area does. UraForce WB60 and WB58 are specified as hygienic washable coatings for walls as well as floors.

The homes guide gives no single lifespan: it depends on the substrate, the application and the use. Sweep grit before it scratches the finish and mop with a neutral cleaner; avoid abrasive pads, strong solvents and acids; a textured anti-slip floor needs a soft brush rather than a mop. A worn topcoat can be recoated without removing the floor. Ask for care instructions and the written warranty terms with the quotation.

An overlay within 13 mm over one existing layer, with the floor traps untouched, needs no permit. Hacking and re-laying floor finishes needs HDB's renovation permit, applied for by a contractor on HDB's Directory of Renovation Contractors, and all renovation work in a flat, permit or not, must be done by such a contractor. Hacking and tile cutting run 9 am to 5 pm on weekdays only, and removal of finishes may take no more than three consecutive days. In a new flat, bathroom and toilet finishes cannot be replaced for three years from the block's completion.

On a floor already at screed, epoxy gives a seamless floor with no grout lines, laid in days; tiles are harder, cooler underfoot and easier to repair locally, with a longer track record in Singapore homes. If the old tiles must come out, both routes carry hacking and disposal at about S$3–8 per sq ft plus levelling. Tiles remain the safer choice where the floor will be wet every day unless the epoxy finish carries a real wet slip rating.

Advertised contractor prices seen on 26 September 2026 put a floor-only epoxy or flake overlay at roughly S$650–1,200 per HDB toilet, with walls adding about S$1,150 per toilet, because a small room is priced as a minimum-charge job rather than by area; lead-in prices of S$299–449 on classified listings are starting figures, not quotes. These are market ranges, not Rayson quotations. The full tables and their sources are on the epoxy flooring cost guide.

Rayson's published floor systems are plain and broadcast industrial epoxies: HydroShield WE40 gives a coloured water-based epoxy, UraForce WB58 a coloured topcoat and WB60 a clear topcoat in gloss, satin or matt. Decorative flakes are chosen and supplied by the applicator; they are not a Rayson product.

In a condo or landed home, Rayson quotes and contracts the job, and an applicator in the Rayson network inspects the floor, runs a test patch and installs it; the workmanship warranty is set out in Rayson's quotation. In an HDB flat, HDB's rules let only a contractor on its Directory of Renovation Contractors take on renovation work, so there a listed applicator quotes and contracts with you directly. Rayson formulates the water-based epoxy HydroShield WE40, the polyurethane topcoats UraForce WB60 and WB58, the solvent-free epoxy FloorGuard R50 and their primers in Singapore, has them made to its specification by its production partners, and publishes every data sheet.

Yes, and it is a different job: a chemical anti-slip treatment of the existing tiles, with no hacking and no change to the floor. See the anti-slip floor treatment page, and the anti-slip cost guide for the published prices and HDB's EASE subsidy.
