What is simen kilat?

Simen kilat is the Malaysian name for a smooth, shiny cement floor: a screed trowelled smooth on site. The same polished concrete look can go over an existing floor as a thin overlay: in KL, Selangor and Penang, the IFS overlay is laid by Rayson-authorised applicators, with nothing broken out.

Before you choose

Polished concrete, simen kilat or an overlay: what is the difference?

Polished concrete is a slab ground and polished; simen kilat is a cement screed trowelled smooth and shiny on site; an overlay is a thin, coloured concrete layer laid over the floor you already have. All three give the grey mineral look, but only the overlay goes over tiles without breaking them out.

That is why the overlay suits renovations in condos, shops and cafés: the old floor stays, the level rises by only millimetres, and the colour and aggregate are chosen on a sample. Where a new floor is laid, IFS’s polished concrete slab, which IFS states at a minimum of 25 mm, is the alternative.

Can the overlay go over my tiles?

Over tiles that are firmly bonded, yes: the applicator taps every tile, takes out hollow ones, repairs cracks and checks the moisture before the overlay. Hollow tiles and a damp slab are common reasons an overlay fails, so both are dealt with first.

Even a thin overlay raises the floor, so door clearances, thresholds and floor traps are checked at the site visit, and the edge where it meets another floor is agreed before the job.

Does polished concrete crack or stain?

An overlay follows the floor under it, so cracks and hollow spots are repaired first and the slab’s movement joints are carried through rather than covered. Stains are kept out by the finish the IFS system specifies; oil and acidic spills such as vinegar are wiped up quickly.

Simen kilat, by contrast, often shows fine hairline cracks as the screed cures, which is part of its raw look. The care regime for the overlay is explained at handover.

Is a polished concrete floor slippery?

A smooth, finished concrete floor can be slippery when wet, like polished stone. At entrances, in kitchens and wherever water is tracked in, the applicator shows on the sample board how much grip the chosen finish has, and where a mat or a different finish is wiser.

In bathrooms, the overlay is a finish, not a waterproofing membrane: the applicator confirms on site whether SealForce WB20 goes underneath first, on concrete, render or screed.

A first guide. The applicator confirms the right route for your floor on site.

What you see

The signs

  • Tiles you want gone without hacking them out
  • A café, shop or showroom that wants the raw concrete look before an opening date
  • A worn screed or old coating that needs a new surface
  • A feature wall or staircase in the same finish as the floor
Why it happens

The usual causes

  • An overlay laid over hollow tiles or a damp slab
  • Simen kilat that cracks finely as the screed cures
  • A patched slab ground and polished, so every repair shows
How the job runs

From three photos to a finished job

  1. Three photos, then a sample

    The floor wide, the surface close and a look you like; colour and aggregate are chosen on a sample board.

  2. Check the base

    Tiles tapped for bond, cracks and hollow spots repaired, moisture checked, PrimeBond E20 where the IFS system calls for it.

  3. Lay the IFS overlay

    Applied in IFS’s four steps to the specified thickness, on floors, walls or stairs.

  4. Cure and hand over

    Kept off until cured; the care regime is explained at handover.

What to send

Three photos are enough for a first quotation

  1. The floor or wall, wide
  2. The surface close: tile, concrete or screed
  3. A photo of the look you want, and the opening date for a shop or café

What it costs

What does polished concrete cost in Malaysia?

Per square foot, quoted after inspection by the applicator for your area. Five things decide it: the area, what is underneath (tiles, concrete or screed) and its repairs, an overlay or a new slab, walls and stairs against open floor, and the colour and aggregate chosen. A wet area that needs a membrane first is its own step. Rayson publishes no price list.

The Rayson difference

An installer buys whatever is on the shelf. A Rayson-authorised applicator installs what Rayson makes.

01

The maker writes the specification

The system is specified by the company that makes the material, and installed by an independent applicator Rayson has authorised, not chosen from whatever a supplier had on the shelf that week.

02

A data sheet for every layer

Every Rayson material on your floor or roof has a published technical data sheet. You can read what went in, and so can your consultant.

03

Two warranties, two companies

Rayson warrants the material as its maker. The authorised applicator, an independent company that contracts with you, warrants the workmanship. Each warranty is issued by the company responsible for it.

04

Same materials on both sides of the Causeway

The products, data sheets and application methods are the ones Rayson publishes in Singapore. Nothing is rebadged for Malaysia.

05

Materials direct, for your own crew

Contractors and facility teams buy the same materials direct from the maker, with application guidance. The applicator is there when you want the job done for you.

The practical details

Questions people ask

Who installs it in KL, Selangor and Penang?

An independent, Rayson-authorised applicator in your area: Kuala Lumpur and the Klang Valley, including Petaling Jaya, Shah Alam and Subang Jaya, or Penang, island and mainland. It inspects, quotes, contracts with you and warrants the workmanship; Rayson is not the installer. Elsewhere in Selangor is confirmed per enquiry, and Johor has its own page.

Whose products are the overlay and the slab?

Both are products of Industrial Floor & Systems Pte. Ltd (IFS), under IFS’s own terms. The Rayson primer and membrane used under them have published data sheets, and the combined build-up is confirmed on a sample board before your job.

How long does a polished concrete overlay take?

Several working days: repairs to the base and any primer, the overlay’s four steps, then the cure before the room is used. For a shop or café, the applicator plans the programme back from your opening date.

Can it go on walls and stairs?

IFS makes its overlay for walls as well as floors. Stair edges and grip are checked at the site visit, and the finish for each surface is confirmed on a sample board.

Who gives the warranty?

Three parties, each for its own part: Rayson for its layers as their maker, IFS’s terms for the overlay or slab, and the Rayson-authorised applicator for the workmanship. All three are written into the quotation.
