What is Pool Plastering?

Types of Pool Plaster
Marble plaster
The plaster most frequently used now is marble plaster. And the white is the most popular one which is cheap and lasts for 9 to 12 years.

The disadvantage is that it costs more than white marble plaster, but it has a little longer lifespan. This kind of plaster will last between 10 and 15 years.
Pebble Aggregate
Pebble aggregate plaster is made of smooth stones or crushed rock mixed with cement. The pebbles and stones also provide an incredibly robust surface that may last up to 20 years, longer than any other form of plaster on our list.
The first drawback of this kind of plaster is its expensive price. The stones and pebbles can conceal and support the growth of germs and algae. It will be considerably harder to scrub and maintain the rough surface.
Tile Finish
Despite not being plaster, tiles are a fairly common choice for pool lining. The tiles, directly put on cement, offer a few benefits over the other plaster forms. The tile’s smooth surface is simple to clean and prevents germs and algae from having a place to hide and thrive. A tile finish should last anywhere from 12 to 18 years.
Because tile must be installed piece by piece, it can be more expensive and take longer to install than other types of plaster.
