HOW TO RESURFACE
It is imperative that the concrete pool shell being renovated is prepared correctly, prior to the application of Quartzon render. Below are some basic guidelines to follow when preparing the shell.
Remove interior coating completely, wet sandblast or gritblast and follow with an acid wash. Hose down and remove any loose material and residue.
If insufficient key for bonding, ‘sparrow peck’ surface with scutcheon or ‘kanga’ hammer and/or apply key coat as described above.
To ensure a good bond we recommend a BondKey coat or slurry coat be applied in all pool renovations. Broom finish to provide a good mechanical key.
Marblesheen or Pebblecrete
Remove any ‘drummy’ or deteriorated areas completely back to the concrete pool shell. Fill these areas with a strong, cementitious render. It may be necessary to remove the old interior completely if unsound. ‘Sparrow peck’ old surface with scutcheon or ‘kanga’hammer if required.
Using a diamond saw, make two cuts, the first directly below the tile band and the second 150mm below the tile band. Remove a ‘V’ section of the old interior up to the tile band.
Acid wash then water blast to remove dust/organic debris and thoroughly hose off. All residue of acid and debris must be removed.
Acid wash and/or re-grout tiles if needed prior to Quartzon application.
Apply the BondKey coat or slurry bond coat at 1-2mm thickness as per instructions. Broom finish to provide a good mechanical key.
Applying the Quartzon
Quartzon is rendered in a similar manner to pebble, marble sheen and many other cement-based pool plasters. After the rendering is complete, that’s where the similarity ends.
Rather than using a high-pressure water blaster to remove the top layer of cement and expose the course aggregates (as in pebble plaster), Quartzon is trowelled to a smooth even finish.
The following day your pool is then carefully acid washed, to remove the fine layer of surface cement slurry and expose the brilliant coloured aggregates and a smooth even finish.
Another advantage of Quartzon is that the product is premixed in bags which gives you the confidence that you are getting a premium product that will result in the exact colour you have chosen.
Upon installation, Quartzon will provide you with a comprehensive care guide that offers step by step instructions on how to best look after your pool.
When compared with other pool renders, cleaning and maintaining your Quartzon surface will be quick and simple. We recommend the use of a tile band to prevent a waterline from forming on your pristine Quartzon surface.
Bondkey Scratch Coat
Manufactured by the makers of Quartzon, BondKey has been specifically designed as a preparation coat for surfaces that will be permanently submerged under water – making it ideal for swimming pool renovations.
Containing unique polymer additives, specialised cements and graded aggregates, BondKey creates a superior, slurry bond coat for cement-based render applications.
Manufactured by the makers of Quartzon, EP Render is a pre-blended cement render specifically designed for application underneath pool tiles and pool tile bands.
Unlike site mixed renders, EP Render requires only the addition of water and includes special additives which make it easy to apply. It also offers superior adhesion, increased strength and long-term coating integrity.
You can also be assured that the product’s formulation has been rigorously tested to ensure all polymers and additives will not break down or re-emulsify under water.
