Basic Swimming Pool Plaster information
Understanding different Plaster Finishes
Pool Plaster is a combination of white Portland cement, mixed with an aggregate...
- Marcite – a blend of white cement and white marble coupled with several additives that enhance the plasterer’s ability to pump, trowel and cure the plaster.
- Exposed Aggregates – A blend of white cement, and a mix of white marble and natural or ceramic coated quartz aggregates.
- Pebble Finishes – A blend of white cement and high silica content rounded pebbles.
- Quartz Plasters – A blend of white cement and silica quartz
that has been specially sized and graded.
Testing of swimming pool water is typically either on site, at the pool, or you can have a computer analysis of your pool water carried out.

"Black Algae"
Black algae is one of the most difficult Algae to control and
eliminate. It appears a black discoloration or a tar-like deposit.
It is difficult to remove because the outer layer is
polymucosaccharide, which acts as a water repellent barrier and
shield the underlying algae from contact with the chemically-treated
water.
In addition to shock treatment, application of a polymer algaecide
is recommended, The pH should be lowered to around 7.2, and pool
jets directed towards the affected areas. Also, by adding a quart
algaecide, it acts as a wetting agent that will help the chemicals
penetrate through the polymucosaccharide barrier.
Too much chemicals
Other than costing you unnecessary money, too much chemicals can damage your equipment. Although the piping is corrosive resistant, the Power Element in the heater might need replacing more often. This gets corroded quicker with high amounts of chlorine, or high amounts of metal in the water.
Discoloration or staining of plaster
Over dosage on chemicals tends too hasten the process of
discoloration of plaster over time. This can be slowed down by
maintaining the correct Ph balance of the pool water.
