Specialist knowledge is required to meet all current demands on bathes and wellness areas and extreme applications like swimming pools with permanent water pressure from inside. That has an impact on the technical design, of course also on the professional sealing and installation of ceramics and natural stone coverings, and requires important planning: standards and guidelines, moisture exposure class, pool construction, initial start-up and cleaning, etc. Ceresit supports the planning and execution with a comprehensive range of user-friendly products and detailed system brochures - solutions that provide the highest possible security for building owners, planners and installers.
Step 1: Substrate preparation
Before starting with tiling installation in swimming pools, a chemical water analysis to determine the type of water to be used in the pool (thermal, brine or seawater) is needed in order to take the right choice of building materials.
The position and dimension of the various expansion and construction joints must be decided and unavoidable joints must be sealed by embedding. It is important to ensure the waterproofing measures are based on the predefined moisture exposure classes. Before taking further steps, check that the screed and substrate is sufficiently dry.
Step 2: Waterproofing
When waterproofing swimming pools, it is crucial to comply with the regulations for swimming pool construction. The products to be used requires confirmation of suitability and certification as system provided through a national test certificate issued by the building authorities. Alternatively, confirmation of suitability can be provided by a European Technical Approval (ETA). Ceresit offers certified systems of liquid-applied water impermeable products for use under ceramic tiles bonded with adhesives - proven success for waterproofing concrete pools.
Step 3: Tiling
In swimming pool construction, much depends on the proper choice of materials. This applies in particular to the waterproofing systems and the products for tile installation, which need a general appraisal certificate by the national building authorities or ETA. Ceresit guarantees safe and high-quality certified system solutions that are able to meet the full range of requirements – for the pool itself, the wet rooms and also the dry areas.
Step 4: Grouting
After mixing, the grout can be applied directly from the mixing container with a trowel. If used on walls and floors, the grout is spread with a hard rubber float. Use the float to press the grout into the joints until these are filled void-free and flush with the tile surface. After that, excess grout is removed from the tile surface by using the edge of the float held at a 90° angle. Stroke diagonally to remove as much grout as possible from the surface without pulling grout out of the filled joints.
In order to obtain a uniform, aesthetic appearance and allow easy cleaning, the joints should be left to “mature” (or firm up) after grouting
