This Sydney home has a huge balcony and entertaining area with stunning water views. The stunning vista is let down by an old pool, almost 30 years old, that is in desperate need of a makeover.
The pool is concrete based, with a painted finish and uses chlorinated water. However, over time, the paint has begun to oxidise and lift away from the surface. The owners have decided to replace the base of the pool rather than repainting it, to avoid a similar problem reccurring.
This makeover is by a professional pool renovation company.
1
Firstly, the water is pumped out using a submersible pump and disposed of. It is usually done overnight so the pool is ready for prep work the following day.
2
The hydrostatic valve is removed from the pool. It is vital that the valve be removed in all in-ground pools as it relieves the under pool pressure, caused by the surrounding water table. If not removed a pool can “pop” or float out of the ground. In extreme cases additional pressure relief holes can be drilled through the floor of the pool. The next step is to cut under the cement coping with a diamond blade to access the existing waterline tiles. These tiles are then removed with a jack hammer. The existing cement coping (which is just going to be covered over with the new coping) is then water-blasted and any cracks repaired. All rubbish is then removed from site. This process takes between 4-8 hours.
3
Sandblasting is necessary to take off the old paint and to make a good “key” for the new surface. A 40 gallon drum, connected to an air compressor, “blows” out dry sand which abrades the paint from the surface. The old paint and sand is then swept away. This takes about 4 hours.
4
In most pool renovations, the coping (brick or pavers) step usually occurs after the waterline tiles have been put in, but in this example it is carried out before. This is because of the type of coping chosen-Megatreat 8000, a “liquid” sandstone. It is a flexible material, applied using a spray gun. The coping takes about 1-3 days.
5
A render band is now applied to the area where the new waterline tiles are to be laid, taking around half a day to complete. The new tiles, (ceramic mosaic), are then laid and grouted. This process takes up to a day and a half to finish.
6
The pool is now almost ready for the new interior surface. The old marble-sheen surface, is checked to ensure that there are no “dummy” or hollow areas. If there are, these are knocked through, and rendered. The interior of the pool then has a “slurry” coat applied. This is a mixture of cement and a bonding agent and ensures good adhesion of the new interior surface. This takes about 4 hours, depending on the amount of dummy areas to be fixed.
7
A pebblecrete finish is chosen, created by mixing a New Zealand white pebble with a blue oxide to create a “Blue Pacific” colour. This mixture is then rendered onto the pool walls and then the floor, creating a seamless finish. (Application takes between 5-7 hours depending on the weather).
There are many interior surfaces to choose from:
Pebblecrete, which is available in various colours, from natural golds to white, both local and imported.
Quartzon, a cement based product available in various colours and rendered onto the pool. It is made from Danish white cement, Queensland river-sand and a coloured quartz product from 3M.
Fibreglass, a durable, smooth surface applied over a number of days. It’s available in various colours.
Ceramic mosaic tiles, a premium surface which is long lasting, smooth and glossy.
Glass mosaic tiles, the ultimate finish. Available in many colours and computer generated designs. It tends to be expensive.
8
The pool is then acid washed, after the render finish has dried. This cleans out the cement, and exposes the aggregate to the final finish. (This takes about 2-4 hrs).The pool is then filled with water and chemicals (mainly chlorine) are added. (It takes about 2 days to fill an average sized pool).

Cost
The total cost of the renovation is around $7,000 - $12,500, including all labour and materials. The price of a renovation can vary greatly, depending on the original condition and the finish chosen.
