Swimming pool tile plan
With the growing popularity of swimming pools, the process of tiling a pool requires careful planning and execution. It typically involves six essential steps to ensure a professional and durable finish.
Before starting, it's crucial to understand the dimensions of the pool structure. For a 50-meter standard competition pool, the actual size must be accurate with a positive tolerance. The standard size is usually 50 meters by 25 meters or 50 meters by 21 meters. The walls at both ends should extend from 30 cm above the water surface to 80 cm below. The length error should not exceed +0.01 meters, and after installing an automatic timing touch panel, the total length should be within +0.03 meters. When calculating renovation allowance, consider the thickness of ceramic tiles, adhesive, leveling mortar, waterproof layer, and electronic contact plates. This ensures enough space for adjustments during installation.
Next, choosing a reliable waterproofing method is essential. High-strength impervious concrete should be used during pouring and properly compacted. After curing, a water test should confirm no leaks. Cement-based crystalline waterproof materials are ideal for the inner walls, as they help bond the tile to the cement mortar. All adhesives, sealants, and grouts should also be waterproof to maintain long-term integrity.
Leveling the inner walls is another critical step. After leveling, the actual size of the 50-meter (or 25-meter) wall should be slightly larger to account for the contact plate, tile thickness, and adhesive layers. The planes on both sides of the pool walls must be parallel and perpendicular, with minimal errors—no more than ±2 mm per square meter. The depth of the pool should align with the tile module to meet usage requirements.
Setting the benchmark and positioning lines is important for accuracy. Once the inner walls are leveled and cured, a baseline should be established. For a 25-meter pool, the centerline of both ends should be marked, and the walls should be divided into sections of 2.5 meters or 20 bricks. Horizontal elevation must be precise, within ±2 mm, and grids should be laid out for consistency. These baselines help prevent any accumulation of errors during the tiling process.
The tiling order starts from one end of the pool, moving across the bottom to the other side. Standard competition pools use specific tile patterns, such as the deep blue lane marking line, which should be laid out before tiling. Tile sizes, like 244 x 119 mm with a 6 mm joint, require careful alignment. Check X and Y-axis grid lines every 2-3 meters to avoid misalignment.
For competition pools, non-slip wool bricks are used below and above the waterline, including lane markers. The final size of both ends must be within 50 meters ±0.02 to 0.03 meters. After installing the touch panel, the length error should still remain within this range.
When applying the adhesive, the surface must be clean, free of dust and oil. Apply the adhesive evenly using a 10mm notched trowel, with a thickness of 7–8 mm. Wait 15 minutes before laying the tiles. Avoid pre-applying adhesive over large areas, and never lay tiles until the adhesive is fully bonded. Ensure that the tiles are aligned correctly and check their size for ±2 mm deviations.
At both ends of the pool, anti-slip tiles should be placed from 300 mm above the water to 800 mm below. The final surface length must meet competition standards, with a maximum error of 50 meters ±0.01 to 0.03 meters. On the sides, non-slip pit pattern bricks should be applied according to the layout details, ensuring that both sides and ends have a level error no greater than ±2 mm.
Tiles must be left undisturbed for at least two days after installation. Sealant should be applied using a conventional method, and joints should be compacted with a special tool. Any excess adhesive or sealant on the tile surfaces must be removed immediately with a damp cloth.
After one week of curing, the pool can be safely filled and used. Following these steps ensures a high-quality, long-lasting tiling job that meets both functional and aesthetic standards.
