Plasterer skim-coating a wall to a smooth level finish in Singapore

Other Services

A better finish starts with a better foundation.

02

Plastering, skim coating and cement screed works to improve surface condition before the final finish is applied.

Why preparation matters

Even. Sound. Ready for what comes next.

Unevenness, weak areas and unsuitable substrates can show through a new finish. Preparation helps resolve visible defects and gives the selected coating or treatment a more reliable base.

01

Plastering

Repair and levelling work for suitable wall and ceiling surfaces before decoration. Good plastering helps correct localised defects and creates a sound base for later finishes.

  • Localised wall repairs
  • Levelling uneven areas
  • Preparation for paint finishes
02

Skim Coat

A thin finishing layer used to improve suitable wall or ceiling surfaces. Skim coating helps refine texture, address minor surface imperfections and produce a more uniform base.

  • Smoother wall appearance
  • Refining existing surfaces
  • Base preparation before painting
03

Cement Screed Works

Cementitious screed application for suitable floors or surfaces where levelling, falls or a raw architectural appearance is required. The intended finish and use are reviewed before work.

  • Floor levelling
  • Selected wall and floor finishes
  • Substrate preparation
04

Self Leveling Works

Self-levelling compound poured over an existing floor to produce a flat, even plane ready for tiles, vinyl, timber or an epoxy coating. It flows out under its own weight to correct dips, humps and minor falls that a trowelled screed cannot reliably smooth, and cures fast enough to keep a renovation moving.

  • Flat, level base for tiles, vinyl & timber
  • Correcting dips, humps and uneven slabs
  • Preparation before epoxy floor coatings
  • Substrate priming and moisture checks first

Before work begins

The existing condition guides the method.

Preparation requirements vary with the substrate, previous coating, moisture exposure and desired finish. A site review helps define the appropriate materials and sequence before a quotation is prepared.

Diagnosis first

Which treatment does your wall actually need?

Paint magnifies whatever sits underneath it. This is how we match the fix to the fault.

ProblemThe right treatmentWhat it involves
Hairline cracksCrack filling + skim coatCracks opened, filled flexibly, skimmed level and sealed before painting.
Uneven or patchy wallsFull skim coatA thin levelling layer over the whole wall, sanded to an even plane.
Hollow or damaged renderHack off & re-plasterFailed plaster removed to a sound base and rebuilt — patching over hollow render fails fast.

FAQ

Surface preparation questions, answered.

What owners ask before the invisible work that decides the visible result.

What is the difference between plastering and skim coating?

Plastering rebuilds a wall's thickness and structure — used when render is hollow, damaged or missing. Skim coating is a thin cosmetic levelling layer over a sound base, applied purely to get a smooth, even plane for painting.

How long after skim coating can walls be painted?

Once the skim has fully dried — typically a few days depending on thickness, weather and ventilation. We seal the fresh surface first, then paint. Rushing this stage is a classic cause of patchy finishes, so we schedule it properly.

Will skim coating and sanding cover my home in dust?

No. Work zones are sheeted, doorways sealed and sanding is managed with vacuum-assisted tools where suitable. The area is cleaned at the end of every session, not just at handover.

Can you skim coat over old paint?

If the existing coating is sound — we test adhesion first. Flaking or glossy surfaces are prepared or stripped before skimming so the new layer bonds permanently.

What is the difference between cement screed and self levelling?

A cement screed is trowelled on and can be built up thicker, shaped to falls and laid over larger level differences. Self levelling compound is poured and flows out under its own weight to a very flat finish — better for correcting dips and humps before tiles, vinyl, timber or epoxy, but it is not designed to create falls or heavy build-ups.

Do floors need screeding before epoxy coating?

Epoxy needs a level, sound, dry substrate. Worn slabs usually need repair and grinding; where levels are off, a cement screed creates the flat base the coating needs to perform.
