Pools are meant to hold water and provide an impermeable base and many people assume that this base is provided by the tiles. While the tiles to provide a good surface and limit the amount of water that seeps past them, they need additional support and this is provided by the rendering underneath the surface. Here are some ways in which rendering helps:

• Forms A Barrier between the Water and the Substrate Material – Rendering materials are relatively impermeable so they form an effective barrier between the water and the material underneath the pool. Any moisture that seeps through the tile grit is contained and doesn’t go far. The render and the tiles work together to form an even surface.
• Flat and Even Surface – Swimming pool tiles need a flat and even surface or else they won’t be installed properly. The substrate usually doesn’t provide this surface and you need properly applied renders in order to get the job done. We make sure the pool surface is even so the tiles sit flush against it and don’t break or crack because of uneven installation.
• Texture – Rendering also provides a textured surface for the tiles to adhere to. Some concrete bases are too smooth for proper adhesion and rendering can help ensure the surface provides some grip.
• Stand-Alone Render – While most people install swimming pool tiles, you can install the render material without the need for tiles. This specially formulated render is moisture and water resistant, slip resident, and not in any way abrasive. It offers the swimming pool a smooth and even surface and looks good as well.
