Stone Effect Pre-Cast Concrete Kitchen Flooring Deep Cleaned in Arnside

The stone floor in these pictures are in fact pre-cast concrete tiles created to emulate Limestone flagstones laid in a Kitchen in Arnside. You can’t beat the natural beauty of Limestone but these concrete tiles do give the Kitchen that rustic look the customer sought. The odd thing is, it’s actually less expensive to buy real Limestone these days as Pre-cast concrete is not a cheap product.

Unfortunately, in this case, the concrete had been smeared with Ivory Grout during installation and the tiler had failed to remove it after grouting and this had dulled the look of the tile. The customer was led to believe by the Tiler that the off-white colour was indeed part of the stone and had put up with it for several years before we were called out.

Cleaning a Damaged Flagstone Tiled Floor

First of all we conducted a test clean to make sure our usual cleaning system would work as well on pre-cast concrete. I was aware that this type of product has a colour dye added to it which does seem to lose colour over the years and also can lose quite a bit of this dye once we start cleaning with strong chemical’s. Not wanting to risk any depreciation in the colouring I opted instead for the application of a set of Tile Doctor Burnishing pads. The pads are encrusted with industrial Diamonds and come in different grits from coarse to fine and I found that not only did the process remove a lot of the of White grout haze left by the tiler but also gave us a good start to the cleaning process without losing any more of the colour Dye.

The customer has specified they were keen for the floor to have more of a sheen finish, so we finished the cleaning with the rest of the Diamond pads finally ending on the super fine pad. We had to do some edging work where the circular pads could not reach but apart from that the pre-cast concrete responded well to this treatment as you will see on the before and after pictures.

Sealing a Flagstone Tiled Floor

The next day we called back to seal the Kitchen floor to protect it from staining, something that is more than likely in a Kitchen. For this we used a couple of coats of Tile Doctor Colour Grow which not only protects by soaking into the pores of the tile but also restores a lot of the colour that had previously been lost.

For aftercare I explained to the customer that sealers do wear off over time and so to get maximum life out of the sealer they should clean the floor with a pH Neutral Cleaner like Tile Doctor Neutral cleaner. It’s designed for cleaning sealed tiled floors and it won’t affect the colour dye or the Sealer we have applied unlike stronger products will eat away at the sealer over time. Additionally, pre-cast concrete like Limestone is Acid Sensitive and as such products like certain types of the Cillit-Bang range cannot be used on a floor like this as it will cause surface damage.

Green Indian Limestone Patio Treated for Heavy Staining in Windermere

This patio, at a house in Windermere was made of fantastic Green Indian Limestone that despite sounding exotic is widely available in tile shops and building yards. But while it is a very good quality stone, it doesn’t always make for a good patio tile. Tiled patios are rarely easy to keep clean, especially if they are made of a sensitive stone, like Limestone. Over time, damage from weather and other environmental elements can leave these sorts of patios in really poor shape.

The area at this property was covered in outdoor shrubs and trees, including Rhododendrons, which are prone to shedding their leaves. The leaves had intermittently fallen onto the acid-sensitive Limestone and, since the leaves are actually slightly acidic, they can leave some quite deep marks. Other trees with can have acidic leaves include Japanese Maples and Azaleas. In this case, fruit berries from Rowan trees had also dropped onto the patio and crushed underfoot, leaving stains they had proven very difficult for the customer to remove.

In fact, the customer was at the point of giving up on the patio. Power washing was having limited success, failing to remove the deeply embedded marks left by the leaves and berries, amongst other general wear and tear. Thus the customer decided to turn to Tile Doctor for a professional cleaning service.

A year ago, this job would have been a challenge, but Tile Doctor recently bought out a product called Oxy Gel that proved to be an excellent cleaning product in this particular situation. Oxy Gel is a heavily concentrated alkaline cleaner in a gel form so it’s easy to handle. I applied this to the Limestone and left it to dwell for about 20-30 minutes to neutralise the acidic staining, before power washing and extracting the waste water.

A certain amount of manual cleaning with a wire brush was required to remove the particularly stubborn marks, including underneath the Rowan trees where the fruit berries were prevalent. As you can see, the problem was quite excessive in these areas, and without the Oxy Gel even we would have found this job too much of a challenge. We also removed the dirty cleaning water containing the remains of the Oxy Gel using a wet vacuum, as this may otherwise have contaminated the garden soil.

We didn’t seal the patio, as we don’t recommend sealing outdoor stone (although we will occasionally make an expectation with particularly sensitive Black Limestone). This is because external sealers generally can’t cope with exposure to acidic leaves and constant wet weather in the winter. What’s more, if the temperature falls below -5 degrees centigrade, the sealer will start to break up and crumble. As I suggested to the customer, it’s best to power wash patio tiles twice a year – once in spring and once again in late summer.

The results were absolutely fantastic considering the extent of the environmental damage. While such damages can’t always be avoided, this situation proves that with the right cleaning products and techniques, they can be reduced significantly. Needless to say, the customer was very happy with the transformation.
