The floor screeding cost in South Africa sits at R350 to R550 per square metre installed in 2026. A thin self-levelling compound over a sound slab is far cheaper, at roughly R30 to R80 per square metre in materials.
Those two numbers do very different jobs. Picking the wrong one is the most common reason a new floor fails within a year.
Why a level base matters more than the floor on top
Every floor finish has a tolerance for how uneven the surface beneath it can be. Cross that tolerance and the problem shows up in the finish, not the slab.
- Laminate and vinyl planks: hollow spots, clicking joints and separated seams
- Tiles: lippage at the edges, cracked corners, and drummy tiles that sound hollow
- Carpet: visible ridges telegraphing through the pile
- Any floor: a guarantee the installer will not honour
Most flooring manufacturers ask for no more than a 3mm deviation under a 2m straight edge. Old Cape Town homes rarely meet that without help.
How to check your own floor first
- Lay a long spirit level or a straight timber batten across the room in several directions.
- Slide a coin or a tape measure under the gap and note the worst reading.
- Mark low spots with chalk so you can see the pattern.
- Tap the slab with a hammer handle and listen for hollow, drummy areas.
Under 3mm and you are usually fine. Three to about 15mm is levelling compound territory. Beyond that you are into a proper screed.
What the floor screeding cost includes
A traditional screed is a sand and cement layer laid over the structural slab and levelled to a set height. It is a wet trade, and the price reflects both material and labour.
- Installed screed: R350 to R550 per square metre
- Sand and cement material only: R80 to R120 per square metre
- Self-levelling screed material: R150 to R200 per square metre
- Fast-drying screed material: R200 to R250 per square metre
Labour usually accounts for 40 to 60 percent of a screeding quote. Small rooms cost more per square metre because setting up, mixing and cleaning up are fixed costs spread over less area.
What pushes the price up
- Thickness: standard practice is 50mm to 75mm, and more depth means more material
- Falls to a drain: showers, patios and laundries need a deliberate slope
- Access: upstairs rooms mean every bag is carried
- Removing the old floor: add roughly R30 to R80 per square metre
- Damp or crumbling substrate: repairs before anything is poured
Screed or self-levelling compound: which do you need
These are not the same product and they are not interchangeable.
A screed is structural depth. It builds height, corrects a badly out-of-level slab, buries pipework and creates falls. It is laid at 50mm and up.
A self levelling compound is a thin, pourable smoothing layer, usually 3mm to 15mm. It flows out flat under its own weight and fixes surface unevenness on a slab that is already broadly correct. Tile and adhesive standards are published by the South African Bureau of Standards.
- Choose screed when the floor is out by more than about 15mm, when levels between rooms differ, or when you need a fall
- Choose compound when the slab is sound but rough, ridged or slightly dished
- Choose both on rough slabs that need depth and a smooth finish for vinyl
Vinyl is the least forgiving finish of all, because it is thin and flexible enough to show every ridge underneath. Our guide to vinyl flooring installation covers what the subfloor has to look like before the first plank goes down.
How long before you can lay the floor
This is where renovation timelines quietly slip. Screed has to dry, not just set, and drying is slower than most people expect.
- Walk on it: usually 24 to 48 hours
- Traditional sand and cement drying: roughly 1mm per day for the first 50mm, so a 50mm screed needs about 50 days
- Beyond 50mm: drying slows further, closer to two days per millimetre
- Self-levelling compound: often ready for flooring within 24 to 72 hours, depending on depth and product
- Fast-drying screeds: designed to cut weeks off, at a higher material cost
A contractor should confirm the floor is dry with a moisture reading rather than a calendar date. Cape Town winters are wet and slow drying down; a warm dry spell speeds it up.
What happens if you rush it
- Trapped moisture lifts vinyl and warps laminate from below
- Tile adhesive fails to bond properly and tiles go drummy
- Efflorescence, a white salty bloom, pushes through the finish
- Skirtings and door frames absorb moisture and swell
Booking the levelling work in the right order
Sequence saves money. Levelling belongs after wet trades and before finishes, and it usually pairs with other work in the same room.
- Strip the old floor and clear the room completely
- Fix any plumbing, damp or slab cracks
- Screed or apply the compound, then let it dry properly
- Lay the finished floor
- Fit skirtings, then paint
If the room is being redone anyway, ask the same team to price the finish. There is real efficiency in one crew handling levelling and flooring installation together, and it removes the argument about whose fault an uneven floor was.

Frequently asked questions
How much does it cost to screed a floor in South Africa?
Installed screeding runs R350 to R550 per square metre in 2026. Materials alone are much lower: a sand and cement mix is R80 to R120 per square metre, self-levelling screed R150 to R200, and fast-drying screed R200 to R250. Labour makes up 40 to 60 percent of a typical quote.
How thick should a floor screed be?
Standard practice in South Africa is 50mm to 75mm for a traditional sand and cement screed over a structural slab. Thinner layers crack and lift. If you only need to smooth a slab that is already close to level, a self-levelling compound at 3mm to 15mm is the right product instead.
How long does screed take to dry before laying flooring?
The rule of thumb is roughly one day per millimetre for the first 50mm, so a 50mm screed needs about 50 days. Above 50mm it slows to nearer two days per millimetre. Self-levelling compounds are often ready in 24 to 72 hours. Ask for a moisture reading rather than trusting a date.
Do I need screed or self-levelling compound?
Measure the worst dip with a 2m straight edge. Under 3mm usually needs nothing. Three to about 15mm suits a self levelling compound. More than that, or where you need to build height, bury pipes or create a fall to a drain, you need a proper screed at 50mm or more.
What happens if you lay flooring on an uneven floor?
Laminate and vinyl develop hollow spots, clicking joints and separated seams. Tiles crack at the corners and sound drummy. Carpet shows ridges. Most manufacturers require no more than 3mm deviation under a 2m straight edge, and installing outside that voids the flooring guarantee.
