What is Pebble Wash?
It consists of a combination of pebbles and cement mix at the ratio of 70% and 30% and is laid on with cement sand or wall plastering. While the fresh lay pebbles cement topping is in still in plastic stage, special brush is deploy to remove the surface cement slurry to expose the pebbles. The next day, the balance cement stains is to be treated with acid wash. Lastly the finish surface is then sealed with a 2 coats of acrylic sealer to protect from dirt and stains as well as improves the overall strength of the floor surface cum gives the job an attractive wet-look.
It's very commonly found in HDB void decks as it's a very durable outdoor finish flooring!!! Lately i even see it on the pillar footing too!
Why did we choose it?
Firstly it was an outdoor finish which was durable. Secondly, there was a wide range of colours to choose from. Thirdly there was a wide range of sizes of pebbles you can choose from too!
One thing to note is which we learnt from the tile person. (yup, where you get your tiles from, most probably they do pebble wash finishes as well) Is that the bigger pebble you choose, the more obvious and visible the cement screed looks in between the pebbles. So the smaller pebbles, the less of a gap you would see, thus a more seamless effect. Unlike tiles, they do not have a groove line. Plus, it comes in a mixture of colours, when it gets dirty, more often you aren't likely to see the dirt so easily. So it's really quite low maintenance.
