Is it ok to use sandstone coping tiles coping tiles around salt-water chlorinated pools?
We are often asked whether it is ok to use sandstone around pools. The short answer is yes, but sandstone around pools MUST be sealed with advanced salt protection. If you want to learn more then read on…
There are two main types of swimming pool water treatment used in Melbourne domestic swimming pools – traditional chlorination system and a salt-water chlorination system.
Most stone is fine to use around the traditional system of pool chlorination. With salt-water pools some precautions need to be made for certain stone types.
High grade bluestone and limestone typically does not react to the salt-water if the correct ph levels are maintained.
Sandstone however has won an unfair reputation for being an inadequate stone for use around pools treated with salt-chlorination.
While it is true that corrosion can occur in sandstone, particularly types of sandstone that are highly porous and contain high levels of silica, it is possible to take preventative measures.
If you choose a salt-water system this does not preclude the use of sandstone as pool coping.
If you use want to use sandstone around a salt-water pool the stone must be adequately protected with a premium anti-salt sealant.
