Swimming Pool Mosaic Tiles

Technical specification, installation and method tips.

If you you're thinking to renovate your pool or to have a new one then this short guide is for. Here we'll have the key points to consider before you make any decision on the tiles.

 Anusual choice for swimming pools are mosaic tiles. These come in different materials and in a great variety of designs. The most common materials for mosaics are: tempered glass, ceramic, porcelain and natural stone. We'll have a closer look to each of them enumerating the most important features.

Glass mosaics

 So far glass mosaics are the most popular one in the industry offering vibrant colours, durability, high resistance to chemicals and charming light reflective surface. The longevity of the glass mosaic tiles is around 20 years. Tempered glass is easy to clean, it's  non-porous, resists chlorine, saltwater and algae. Due to UV strength its colour will stay vibrant for years.

 The most popular finishes for glass mosaics are transparent mosaics which are used for infinity pools. Second come the iridescent ones which will create that shimmering effect. And finally the opaque one for a neutral and muted colour tone.

Ceramic mosaics

Are more budget friendly which will decorate your pool with a big variety of patterns and colours. Made from kiln-fired clay with glazing these are less expensive than glass but may fade over time. Due to the fragile nature of the material ceramic mosaics are more prone to chipping. Being a porous material makes it highly likely to stains. Ceramic mosaics are often used for residential and cost-efficient pools.

Porcelain mosaics 

Porcelain mosaics  are  an often choice when it comes to pool mosaics due to their durability and resistance to chemicals. It offers good protection against chlorine, saltwater and pH fluctuation. In comparison with ceramic mosaics porcelain has less water absorption and a much longer life. Being a very strong material allows porcelain to offer low maintenance, high glazing and resistance for UV. As a modern material this can copy the most sophisticated prints for natural stone, wood, intricate colours and patterns. Another key point to consider for swimming pool mosaics is anti-slip rate which starts at R10-12 and provides safety with its textured surface. The best finish for the mosaics is  the matt one perfect for pools and decks. Through-body porcelain provides better colour as it goes deeper in the material and can hide chips.

Stone mosaics

Natural stone mosaics  is the first  material used  for swimming pools. There is a variety of different stones like marble slate, granite and onyx. Everyones knows about luxurious aspect of carrara or travertine, these materials have to be pre sealed before installation and after and every couple of years.

If you require something dark and textured for your pool area than black slate is the answer, it offers  a organic and stylish feel.

Granite is the best when you are looking for durability and great resistance against chemicals.

Onyx is a translucent material but be aware this is quite delicate, might break very easily.

Stone mosaics are sometimes combined with glass mosaics for a shimmering effect.

   Let's have a look at what designs and shapes of the mosaic tiles we can have

The usual size of a mosaic sheet is around 30x30cm, thickness may be different 8-12mm accordingly  with the actual material for the mosaic. For intricate designs you can have 1x1" or 2x2" size mosaic.

For larger tiles the size varies a lot, starting from 5x5cm to 1x1m if you intend to achieve a seamless look. Hexagons, squares, pebbles or floral motifs, are a few of the most common shapes and patterns for mosaic tiles.

The finish surface of the a mosaic tile can be polished (smooth and glossy);  honed (matt and less slippery), tumbled (natural and rustic texture). All mosaic sheets have to be frost resistant, non slip and with low water absorption. For the mosaics we have to use epoxy based adhesive for underwater bonding and polymer modified and mold resistant grout. 

       What are the maintenance rules for mosaics in the swimming pool?

Regular cleaning is very important for the life and  the look of the swimming pool mosaics. It is crucial to look after these with the correct actions. It is recommended to clean the area of the pool with nylon brush which prevents algae building. Also you have to use a pH-neutral stone cleaner and avoid acids or abrasives that might damage natural stone. For glass mosaics things are simple, vinegar-water mix can be used. If you have opted for natural stone like marble and travertine please be prepared to seal them every 6-8 months. Avoid  oil-based sealers near water.

Another important aspect for pools is the chemical balance. The water pH has to be around 7.2-7.6, the alkalinity 80-120ppm and the calcium hardness 200-400ppm. All of this measures are meant to protect the mosaic surface. The imbalance of the water can etch marble or can cause efflorescence on grout. Prevent the stains by wiping all the spills promptly, cover the pool to prevent any debris. Every year the grout lines have to be inspected fro cracks and repaired with waterproof caulk. Avoid pressure washing which can dislodge the  grout.

Now you should know a little bit more about swimming pool mosaic tiles and it should be easier to understand the specific qualities of these. It is very important to make the correct decision ahead of the time so you have the best possible results with your project.
