How do you stop a concrete floor dusting?

Grind off the weak top layer, repair it, then seal it. Rayson UraForce WB60, a water-based clear polyurethane, seals and dustproofs concrete in two coats and keeps the concrete look; HydroShield WE40 does it in colour. Floors under heavy forklift traffic need a floor system instead.

Before you choose

Why does a concrete floor keep dusting?

Because its top layer is weak: laitance left by finishing, or concrete that dried too fast, wears away under wheels and brooms, and new dust comes up from the open surface every day. Sweeping only exposes more. Grinding removes the weak layer, and a sealer binds what is left.

Oil, spills and cracks make it worse. The survey looks at how weak the surface is and what crosses it, because a dusting slab under forklifts needs a floor system, not a clear coat.

Clear or coloured?

Clear to keep the look of the concrete: UraForce WB60 inside, in gloss, satin or matt, or SB65 outside. Coloured to hide stains and patches: HydroShield WE40 or WE45, two coats at 6 to 8 m² per kg a coat, the first serving as the primer.

A clear coat shows everything beneath it, the slab’s colour, cracks, repairs and stains, which is part of its look; a sample patch shows the result before the floor is done. A coloured seal coat evens the floor out, and WE45’s data sheet adds rubbish chute coatings to the floors it lists.

Indoors, outdoors or in an occupied building?

In an occupied office, shop, school or factory: UraForce WB60 or HydroShield WE40, both water-based, with WB60 stated low in VOCs and odour. On an open-air floor, a porch, stone or a wall in the weather: UraForce SB65, solvent-based, with outstanding weather durability and no yellowing.

SB65 needs ventilation while it cures, so it is not for closed, occupied rooms. On dense concrete it goes over PrimeBond S30 where the slab needs priming. Epoxy seal coats such as WE40 yellow outdoors, so outside the clear choice is SB65.

Is a sealer enough for a warehouse or factory?

For storage halls under normal to medium-heavy wear, a seal coat can be: HydroShield WE40 is listed for warehouse and production floors in that service. Under forklifts all day, impact and pallet drops, no: those floors take LevelShield SL120 self-levelling epoxy or FloorGuard R50.

WB60 and SB65 are thin protective films, not wearing screeds. The specification splits the floor by zone, so the aisles get a floor system and the quieter areas a sealer.

From the data sheets. The survey confirms which suits your slab, traffic and light.

Where it suits

The floors it suits

  • A warehouse, store or workshop floor that dusts onto stock and shelves
  • A café, shop or office that wants the bare concrete look without the dust
  • A data centre or electronics plant with bare concrete in voids and service areas
  • A porch, terrace or stone surface outdoors that stains and weathers
  • A plain cement floor at home, polished or not, that needs protecting
Where it goes wrong

Why these floors fail

  • Sealed without grinding, so the coat sits on the weak layer and wears off with it
  • Laid on concrete younger than 28 days or wetter than 5%
  • A clear coat used to hide stains it can only show
  • A solvent-based sealer applied in a closed, occupied room
  • A thin sealer asked to carry forklift traffic
How the floor is laid

From the bare slab to a floor in service

  1. Survey the slab

    How weak and how dusty the surface is, oil and stains, moisture (below 5%) and age (at least 28 days), what crosses the floor, and whether it is indoors or out.

  2. Grind and repair

    Mechanical preparation to sound concrete, the dust vacuumed off; cracks filled with PatchBond TX80 and broken patches rebuilt in MortarBond EM90. Repairs show through a clear coat, as the sample patch makes plain.

  3. Seal

    UraForce WB60 or SB65 in at least two coats by brush and roller, edges stripe-coated first, mixed 9:1 by weight for WB60 and 4:1 by volume for SB65, each used within about 2 hours; or HydroShield WE40 in two coats, the first as primer.

  4. Cure and hand back

    WB60 and SB65 are surface dry in about 6 hours at 25 °C; WE40 reaches its final cure in 7 days. The floor goes back into use when the specification allows.

What to send

Three details are enough for a system recommendation

  1. The floor, wide, and the dustiest patch, close
  2. Indoors or outdoors, what crosses it, and the look you want: clear or coloured
  3. The area in m² or sq ft, and the town

What it costs

What does sealing a concrete floor cost in Malaysia?

Sealed by a Rayson-authorised applicator, a concrete floor is quoted per square foot after a look at the slab. Five things decide it: the area, how much grinding and repair the surface needs, clear or coloured, indoors or out, and the programme around your operation. A sealer costs less than a full floor system, and is specified where the traffic allows it. Material ordered direct is quoted per order. Rayson publishes no price list.

Who stands behind the job

  • Rayson makes the materials, writes the specification and warrants the material. It supplies them direct in Malaysia through Epovex Coatings Sdn. Bhd., with the data sheets; supply and delivery are confirmed for each order.
  • The Rayson-authorised applicator for your area an independent company authorised by Rayson, contracts with you, inspects, quotes, lays the floor and warrants the workmanship. Or your own flooring contractor orders the material and lays it to the data sheet.
  • Rayson is not the installer and is not a party to the installation contract. Two warranties, two companies.

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

Will a sealer make the floor slippery?

A gloss clear coat is smoother than bare concrete and can be slippery when wet. WB60 and SB65 also come in satin and matt, and where the floor gets wet, a textured system such as GripSafe AP12 or FloorGuard R50 broadcast with aggregate is the safer choice.

Is there a clear epoxy floor coating?

Rayson’s clear floor coatings are polyurethane, not epoxy: UraForce WB60 indoors and SB65 outdoors. A clear epoxy yellows in daylight, which shows more on a clear coat than on a coloured one; an aliphatic polyurethane does not, and both come in gloss, satin or matt. Where a coloured epoxy seal coat is wanted, HydroShield WE40 does that in two coats.

Is a sealer the same as a densifier?

No. A densifier soaks into concrete and reacts with it; Rayson does not make one. UraForce WB60 and SB65 are polyurethane clear coats that form a film on the surface, and HydroShield WE40 is an epoxy seal coat.

Can I seal the floor myself?

Yes, with the data sheet: Rayson sells WB60, SB65, WE40 and WE45 direct through Rayson Malaysia (Epovex Coatings Sdn. Bhd.), with supply confirmed for each order. The slab must be ground first, and the two parts mixed by weight or volume as the data sheet sets, then used within the pot life.

Can a sealer go over an old coating?

Not as a rule. WB60 and SB65 are made for mechanically prepared concrete, stone and prepared metal, so old paint or a failing coating is ground off first.

Who gives the warranty?

Rayson warrants the material as its maker when it is laid to the data sheet; the Rayson-authorised applicator warrants its workmanship, and both are written into the quotation. A floor laid by your own contractor carries that contractor’s workmanship terms.
