Understanding polished concrete

Polished concrete is a complete grinding, densifying and finishing system

At AK Surface Solutions, we classify polished concrete from a 200 grit finish upwards. The finished appearance depends on the original slab, the depth of grinding, the aggregate exposure and the polishing sequence used.

A successful polished concrete floor begins before the grinding machine reaches the surface. Concrete design, placement, curing, power floating and protection during construction can all influence the final appearance.

The polishing system should be selected according to the condition of the slab, the level of aggregate exposure required, the expected traffic and the final level of protection and gloss.

Selecting the visual finish

Cream finish or exposed aggregate polished concrete?

The depth of the initial grinding stage determines how much of the concrete surface and aggregate becomes visible.

Light surface polish

Cream finish

A cream finish is a light surface polish where the top power-floated surface is retained and polished without heavy grinding into the aggregate.

  • Maintains more of the original surface character
  • Shows limited or minimal aggregate exposure
  • Depends heavily on good placing and power floating
  • Usually requires a consistent, well-finished slab
Deeper mechanical grinding

Exposed aggregate finish

An exposed aggregate finish is created by grinding deeper into the slab to reveal the sand and larger aggregate beneath the original surface.

  • Produces a more decorative aggregate appearance
  • Can range from light exposure to full exposure
  • Requires a controlled and consistent grinding process
  • The aggregate distribution within the slab affects the result
Before the floor is poured

Planning concrete for a polished finish

When polished concrete is part of the final design, the slab should be planned, placed and protected with the finished appearance in mind.

01

Confirm the intended finish

Decide whether the project requires a cream finish, light aggregate exposure or a deeper exposed aggregate appearance before the slab is installed.

02

Choose the concrete carefully

Concrete strength, aggregate type, aggregate colour, cement colour and admixtures can all influence the final appearance after grinding and polishing.

03

Place the slab consistently

Inconsistent placing, excessive movement of aggregate or uneven finishing can become visible once the floor is ground.

04

Power-float the surface correctly

A cream finish relies heavily on a consistent power-floated surface because heavy grinding is not used to remove the top layer.

05

Allow proper curing

The slab must be allowed to cure and develop sufficient strength before the main grinding and polishing process begins.

06

Protect the floor during construction

Prevent paint, plaster, adhesives, oils, impact damage and deep contamination from affecting the concrete before polishing.

Typical working sequence

Grinding, densifying and polishing concrete

The exact tooling and number of stages depend on the slab, the finish required and the performance of the previous step.

01

Inspect and test the concrete

Check hardness, flatness, contamination, cracks, coatings, curing compounds and previous repairs. Complete a test area before confirming the full system.

02

Complete the initial grinding stage

Use the correct diamond tooling to remove coatings, flatten the surface or expose the required amount of aggregate.

03

Repair cracks, joints and surface defects

Complete suitable repairs once the condition of the concrete is clearly visible. Remove excess repair material before continuing.

04

Refine the scratch pattern

Progress through the grinding stages without leaving deep scratches from the previous grit. The floor should be cleaned between each stage.

05

Apply the lithium densifier

Apply the selected densifier evenly when the surface is open and ready to absorb the treatment. Do not allow uneven residue to dry on the floor.

06

Continue the polishing sequence

Progress through the selected resin polishing stages until the required clarity, reflectivity and finish level have been achieved.

07

Apply the protective guard

Apply the selected concrete protection treatment in thin, even coats and remove any excess according to the product instructions.

08

Burnish the finished floor

High-speed burnishing helps refine the final finish, improve gloss and develop the protective treatment where the selected system requires it.

Two-part protection system

Use a densifier first, then protect the finished surface

Densification and surface protection perform different functions within a polished concrete system.

Stage One

Lithium densification

A lithium densifier penetrates into suitable concrete and reacts within the surface. It is used to increase surface density, improve hardness and support the polishing process.

  • Apply to a clean and receptive surface
  • Spread evenly across the working area
  • Do not allow puddles or uneven residue to dry
  • Continue polishing after the required reaction period
Stage Two

Gloss and stain protection

A protective guard is applied after the main polishing sequence to improve resistance to staining, wear and everyday contamination while enhancing the finished appearance.

  • Apply in controlled, thin coats
  • Maintain consistent coverage
  • Remove excess product before it dries
  • Burnish with suitable high-speed equipment
Practical application

Applying densifier and concrete guard

Always follow the individual product instructions and complete a test area before treating the full floor.

Lithium densifier

Apply evenly to receptive concrete

  1. Vacuum and clean the floor thoroughly.
  2. Confirm the concrete is ready to absorb the treatment.
  3. Apply the densifier evenly across a manageable area.
  4. Keep the surface consistently wet during the required working period.
  5. Move excess treatment from wet areas into dry areas.
  6. Remove remaining excess before residue dries.
  7. Allow the floor to dry before continuing the polishing sequence.
Protective concrete guard

Use thin coats and controlled burnishing

  1. Make sure the polished floor is clean, dry and free from dust.
  2. Apply a very thin and even coat with a suitable applicator.
  3. Avoid heavy application, puddles and overlapping wet edges.
  4. Allow the first coat to dry according to the product instructions.
  5. Apply an additional thin coat where required.
  6. Burnish the surface with suitable high-speed equipment and pad.
Ongoing floor care

Maintaining protected polished concrete

The correct cleaning system helps preserve gloss, reduce scratching and extend the performance of the protected floor.

Routine maintenance

Remove dry dust and abrasive debris frequently. Use the correct pad, cleaning chemical and scrubber-dryer settings for the floor and level of contamination.

Do not rely on highly aggressive cleaning chemicals for everyday maintenance when a suitable neutral or maintenance cleaner will complete the task.

Restoring appearance

Areas exposed to heavy traffic may need periodic deep cleaning, additional burnishing or renewal of the protective treatment.

Inspect the floor regularly rather than waiting until contamination and traffic wear become difficult to remove.

Concrete Protection FAQs

These answers provide general guidance for polished concrete preparation, densification, protection and maintenance. Always inspect the individual floor and follow the selected product instructions.

At AK Surface Solutions, we classify polished concrete from a 200 grit finish upwards. Lower grit grinding stages are normally part of the preparation and refinement process rather than the completed polished finish.

A cream finish is a light surface polish that retains the upper power-floated surface with limited aggregate exposure.

An exposed aggregate finish is created by grinding deeper into the concrete to reveal sand and larger aggregate. The final appearance depends on the depth of grinding and how the aggregate is distributed within the slab.

Not every floor is suitable for a consistent cream finish. The result depends on how the slab was placed, power-floated, cured and protected.

Heavy surface damage, poor finishing, contamination or uneven power floating may require deeper grinding, which can expose more aggregate than originally planned.

Once concrete is ground, its cement matrix, sand and aggregate can become part of the final visible surface. Aggregate colour, aggregate size, cement colour, concrete strength and placement quality may therefore affect the completed appearance.

The concrete must be sufficiently cured and strong before the main grinding process begins. Starting too early may damage the surface or pull aggregate from the slab.

The correct timing depends on the concrete specification, site conditions, curing method and polishing system.

A lithium densifier is used to increase surface density, improve hardness, support dustproofing and help the concrete develop a better polished finish.

It penetrates into suitable concrete rather than forming a thick surface coating.

The densifier is normally applied after the main metal grinding and surface-refinement stages, when the concrete is clean, open and able to absorb the treatment.

The exact stage can vary according to the concrete, tooling system and final specification.

Excess product left to dry can create uneven residue, marks or difficult deposits on the surface. The densifier should be spread evenly and remaining excess should be removed before it dries.

No. A densifier reacts within the concrete to improve surface density and hardness. A protective guard is applied later to improve resistance to staining, wear and everyday contamination.

Many polished concrete systems use both treatments because they perform different functions.

The floor should be clean, dry and free from dust. Apply the treatment in controlled, thin and even coats with a suitable applicator.

Avoid puddles, heavy application and uneven overlaps. Allow each coat to dry according to the product instructions and burnish the finished surface with suitable high-speed equipment.

No. The floor still requires regular dust removal, correct scrubber-dryer cleaning, suitable pads and periodic inspection.

A protective treatment helps improve resistance and maintain appearance, but it does not prevent all wear, staining or damage.

The correct product depends on the floor condition and level of contamination.

ULTRALIT BRILLIANT is designed for routine maintenance with scrubber dryers, while ULTRALIT CLEAN PLUS is suitable where stronger cleaning of dirt, grease and industrial contamination is required.

Yes. Provide details about the floor area, concrete condition, existing coatings, required aggregate exposure, polishing level and expected traffic.
