I’ve seen concrete floors with some amazing stones and colours through them. Is it true I can choose the colour of my concrete floor?
Yes and no. If you already have an existing slab then you are limited as the concrete is already there. However you can add a colour dye over the top of the concrete if you don’t like the existing colour. On the other hand, if you are pouring a new slab then you can indeed choose the colour of the stone (aggregate) and the cement. Some examples are below. Click on the arrow.
When is the best time to polish concrete if I have a new slab?
We recommend you get in touch with us as soon as you can. Concrete will take approximately 28 days to cure before we can begin grinding. We can then do the polishing all at once, or in two stages. If we do the procedure in two stages we come in and perform the initial grind and grout, before the frame is erected. We put down a protective coating after this to assure the floor is protected during the rest of the building. Then, just before the plaster is put up we come back in and remove the coating and polish up the floor once again. Otherwise, the option is to do it all in one hit, once the frame is up and the internal walls are tight.
Can Grind & Seal pour my concrete slab?
We can recommend a concreter however we do not pour slabs ourselves. Grind & Seal offer a range of polished concrete services including grind and seals and machine polishes/Hiperfloor, epoxy flooring, concrete coatings, and acrylic sealers. We polish any new or existing concrete.
How cold will polished concrete floors be to walk on?
Unlike tiles which have a very small thermal mass, a concrete slab has a high thermal mass and is actually a very good insulator and therefore will feel much warmer.
How slippery will the surface be?
Put simply, no more than many other surfaces like tiles and timber. However, like tiles and timber flooring, when water is added to the equation it will indeed be slippery. So we recommend in any wet areas or outdoor areas we do a grind and seal, that way we can add an anti-slip agent to the sealer to provide extra traction.
My existing concrete has some cracks in it, can you fix this?
If you have the floor grouted during our procedure this will fill in small cracks and holes, a percentage of which will be masked by the procedure. And with a mechanical polish/Hiperfloor, the procedure actually hardens the floor by as much as ten times it’s otherwise natural strength. However we can never guarantee a crack free surface.
Does polished concrete require a lot of maintenance?
This depends on which procedure you have had done. Mechanically polished concrete (MPC) or Hiperfloors are generally maintenance free for up to 10 years and at that point will simply need a protective (penetrating) sealer reapplied. As for a grind and seal finish, we suggest these are resealed every 5 to 7 years. This figure varies greatly because it is dependent on the quality of the sealer you have selected and the amount of traffic over the floor.
When it comes to stains, will polished concrete stain easily?
We use a penetrating sealer on all of our finishes which is designed to help prevent staining. So generally speaking, no it should not. But please keep in mind that the quicker you are to clean up spills, the less likelihood of any staining.
I’m concerned about the mess from concrete polishing, will there be a lot of dust from the procedure?
Only a small amount of dust is created when we do work with hand grinders. We use a high grade dust extractor when performing the main grind so that there is very little dust in the air. When the job is complete you could expect some areas in your home to look like you haven’t dusted for a few weeks, which is all.
I’ve noticed my existing concrete needs some repairs, can you help?
We sure can. Mechanically polished concrete floors can be repaired quite easily in small areas. However when it come to a grind and seal we usually need to re-finish the entire area otherwise it will look different in the one spot. This usually requires a sand back, and re-seal.
I’ve heard polished concrete can save on lighting cost. Is this correct?
Being a highly reflective surface, we’ve had customers state that they have saved as much as fifty percent on their electricity bills after polishing their concrete.
Can you recommend a good way to keep my polished concrete clean?
A simple micro-fibre mop is one of the very best ways to keep your floor clean from dirt and dust. And to keep your polished concrete floors in tip top shape use a ph neutral cleaner and wipe any spills quickly with water.
Can we have polished concrete inside and/or outside?
Our polished concrete floors are extremely versatile and can be customised to suit a range of requirements, including: Shops, factories, indoor and outdoor areas of homes, including garages, driveways patios, alfresco areas, pool areas and outdoor kitchens. As well as customising the decorative element of your concrete, we can also make it slip resistant and UV resistant through our large range of sealants. For outdoors we recommend a ‘grind and seal’. Indoors you can choose either a ‘grind and seal’ or a mechanical polish (MPC).
Is polished concrete very expensive?
Polishing your concrete flooring is one of the most budget friendly flooring solutions currently available. However, it does vary greatly in price depending on which process you are looking for, grind and seal or mechanical polish (MPC)/Hiperfloor? Other factors like the level of exposure you would like, the condition of the concrete and so on need to be taken in to account. So getting a quote is always best, seeing the concrete, the area (bathroom or kitchen?), the location (upstairs unit or external patio?), will help with your quote as concrete is polished on a price per square metre rate.
