Grouting (or regrouting) is much more than just the "white lines" between tiles. It is the fundamental barrier that prevents water from seeping behind the glass mosaic, protecting your pool's structure and stopping costly tiles from falling off. Furthermore, damaged grout is the perfect shelter for black algae and bacteria. A professional, long-lasting seal is essential to withstand the demands of our Mediterranean climate (extreme heat, salinity). At Servinmosol, we restore your pool to its "newly built" look using state-of-the-art materials and specialized labor.
When is regrouting necessary?
Pool joints suffer from chemicals (chlorine, acid) and the sun. You should consider a renovation if you observe:
- Empty or hollow joints: If you run your hand over and feel the sharp edge of the tile, it is dangerous (causes cuts on feet) and requires urgent attention.
- Stubborn algae: If black or green spots appear in the lines and don't go away with brushing, it's because the grout pore has opened, and algae have rooted inside.
- Falling tiles: This is the final symptom. Water has penetrated behind and rotted the adhesive cement.
Our Application Process
It's not just about "spreading paste on top." For the grout to last for years, preparation is key.
1. Emptying and Chemical Cleaning
We empty the pool and perform a deep acid wash. We use high-pressure washers to remove limescale, algae, and sunscreen residue embedded in the walls. This opens the pores and ensures the new grout adheres strongly.
2. Application and Final Cleaning
We apply the grouting compound, spreading it in all directions to ensure it penetrates to the bottom of the joint. After the exact drying time, we perform a thorough cleaning with special sponges so that no "white haze" remains on the tiles, and the water looks crystal clear from day one.
How long does the regrouting process take?
Regrouting is a quick and efficient process. Normally, it takes between 2 and 3 days depending on the size and current condition of the pool. Our specialized team works diligently to minimize the time the pool remains empty, thereby protecting its structure and allowing you to enjoy it as soon as possible.
Materials: Cement or Epoxy?
We offer two types of finishes according to your needs and budget:
Water-Repellent Cementitious Grout: The improved classic option. We use flexible technical mortars with anti-mold and water-repellent additives. Ideal for standard residential pools.
Epoxy Grout (Premium): The ultimate solution. It is a two-component resin that is totally waterproof, rock-hard, and does not stain or lose color over the years. It is the recommended option for salt chlorination pools or spas.
During the regrouting process, we manually inspect the entire pool shell. If we find loose or hollow mosaic tiles, we replace them before applying the grout to leave the surface perfect.
We recommend doing this work in winter or spring to have the pool ready for the swimming season.
