HDB Renovation Guide Singapore: Cement Screed Walls
This HDB Renovation Guide Singapore looks at cement screed walls for that raw, industrial feel, how to coat them with low-VOC paint, and the upkeep they need in our weather. If you renovate in 2025 or 2026 and want a loft look without tiles, screed is worth a hard look.
What cement screed gives you
Cement screed is a sand-cement layer trowelled onto a wall or floor, then left with a flat, stone-like face. It reads as industrial without the cost of real concrete panels.
I like it for feature walls in living rooms and for bathroom backsplashes where owners want something other than glossy tile. It is tough and easy to repaint later.
The trade is texture. Screed is not mirror-smooth, and hairline cracks can appear as the mix cures. That is normal, not a defect, but some owners hate the look of it.
Cost sits in the mid band. Screed is cheaper than concrete panels but more than paint, and it is wet work done by your HDB-approved contractor, not a controlled hack, so no renovation permit is needed for the wall. In a 4-room BTO reno of S$30k to S$66k, budget it under the roughly 15% painting slice rather than the 20% flooring slice.
HDB Renovation Guide Singapore: low-VOC paint over screed
Bare screed is dusty and porous, so it needs a seal then paint. Choose low-VOC paint to keep indoor air clean, a real concern in a sealed, air-conditioned flat.
- Let the screed cure fully; rushing traps moisture and blisters the coat.
- Apply a primer made for cement so the top coat grips.
- Roll two coats of low-VOC paint, matte or eggshell.
Pair it with E0 boards elsewhere. The eco trend in 2025 and 2026 is less about style and more about not living in fumes.
Maintenance in humid Singapore
Our humidity is the enemy of any raw surface. Screed drinks moisture, so a bathroom screed needs good extraction or it stains and smells.
- Wipe marks early; cement holds stains once they set.
- Keep a fan or window routine in wet rooms to dry the wall.
- Repaint every few years as the coat wears at corners.
Watch the floor load too. Screed adds weight, though a wall layer stays well under the 150kg per square metre limit. A full screed floor is the one to check with an engineer.
Plan the curing window into your timeline. Screed needs days to dry before paint, and Singapore's humidity stretches that, so a contractor who paints too early traps moisture and the coat peels within the one-year defect period.
My honest view
Screed looks great in photos and feels solid in person, but it is not for the fuss-free owner. If you can live with a little texture and a repaint now and then, it gives a flat character that tile and paint alone won't.
Get it done by a DRC contractor who has poured screed before. A bad mix cracks wide, and fixing it means chasing the whole wall back to bare.
This HDB Renovation Guide Singapore note is the one to keep: screed rewards patience. Let it cure, seal with low-VOC paint, and run a fan in wet rooms, and the wall stays clean for years. Spend the saved permit money on E0 boards elsewhere, so the industrial look reads intentional rather than unfinished.
