FAQ POLISHED CONCRETE | CONCRETE FLOOR SYDNEY

FAQ’s

What is polished concrete?

Polished concrete is a multi-step process of grinding, honing, and polishing a concrete surface to achieve a smooth, glossy finish.

What are the benefits?

Where can it be used?

How do you maintain polished concrete floors?

Regular Cleaning: Sweep and mop regularly to remove dirt and debris.
Avoid Harsh Chemicals:Use pH-neutral cleaners to avoid damaging the surface.
Resealing: Periodically reseal the surface to maintain its shine and protect it from stains.

Can existing concrete be polished?

Polishing is only possible if the concrete is sound, stable, and in good condition. Cracks, patches, damage, and other unsightly imperfections are not hidden by the polishing process. If a rustic and industrial aesthetic is desired, polishing the existing concrete is possible, but results will vary depending on the floor’s condition.

Can it be coloured or stained?

Yes, polished concrete can be coloured or stained to achieve a variety of looks. Dyes and stains can be applied to create custom designs and finishes.

What is the cost?

The cost varies depending on factors such as the size of the area, the condition of the existing concrete, and the desired finish. Generally, polished concrete is cost-effective compared to other flooring options.

How long does it last?

With proper maintenance, polished concrete floors can last for decades. Their durability makes them a long-term investment for both residential and commercial properties.

What type of floor can be resurfaced?

Condition: Is it in good condition or does it have pits, chips, and chunks missing? Is it hard or soft concrete?
Soft Concrete: Can be densified to achieve the desired hardness.
Poor Condition: May require self-level resurfacing followed by a microcement finish like Arapido.

Surface Preparation:Is the tile glossy or porous? What surface preparation is required for proper adhesion?
Often, 5-10mm of self-levelling concrete is applied to smooth the surface, followed by a layer of micro-topping like Arapido.
For a Venetian style finish, Sgraffino can be used. For a burnished finish with trowel lines and chatter, Sgraffino is applied with a 16-inch steel cement trowel.

Preparation: Plywood should be sealed to prevent moisture absorption, then a layer of self-levelling cement is applied. This creates a rigid surface to apply a layer of microconcrete like Arapido.

How do we handle logos and uneven surfaces?

A double layer of self-levelling concrete is usuallyinstalled to cover the logo. When installing over a logo, it’s better to have at least 2 pours to have better control over the final level.

Can you resurface a painted concrete surface?

Surface preparation is key. A concrete resurfacing system will adhere to whatever is underneath it, so a peeling and flaking painted floor would not make a good substrate. Grinding and removing old or flaking paint ensures a proper base for the cement overlay, ensuring the desired result and longevity of the floor.

Should we honour expansion joints?

Yes, we recommend honouring expansion joints due to the significant daily movement caused by temperature changes, leading to expansion and contraction in the concrete slab. The unattractive expansion joint undergoes several steps to reduce its size and refine its appearance, ensuring a more aesthetically pleasing finish.
