Waterproofing a shower is not just a crucial task; it’s a fundamental aspect of bathroom construction that safeguards the integrity and longevity of your home. The presence of water and moisture in a shower area, if not properly managed, can lead to a host of problems, including structural weakening, unsightly mold growth, and extensive moisture damage that can permeate beyond the bathroom itself. As such, a meticulous waterproofing process is vital to ensure that these issues are kept at bay.
This guide is designed to walk you through the waterproofing process with precision and confidence, using industry-leading, solvent-free, fast-curing products from BASF PCI®. These high-quality chemicals are specifically formulated to provide a robust and durable waterproof barrier, a critical defense for any wet room environment. By following this step-by-step tanking guide, you will learn how to lay the groundwork for a shower space that is not only moisture-resistant but also maintains a clean and healthy environment, free from the risks of water damage.
We will cover all aspects of the waterproofing process, from the initial preparation of floors and walls to the final application of sealants. Each step is crucial in creating a watertight seal that stands up to the daily exposure to water and the challenges of a humid bathroom environment. With this comprehensive guide, you will gain the knowledge and techniques to effectively waterproof your shower, ensuring a safe and enduring finish that allows you to lay your tiles with confidence, knowing that the foundations of your shower are secure.
1. Preparation
Start with a solid foundation by ensuring all surfaces are structurally sound, clean, and weight-bearing. Remove any contaminants that could affect adhesion, such as oil stains, waterproof adhesive residues, or loose particles. Confirm that new cement screeds have a moisture content of no more than 4%, and anhydrite screeds are below 0.5%, as verified with a CM meter.
2. Priming
Priming the walls and exterior surfaces not only seals the area but also extends the life of subsequent coatings. Use a product like Gisogrund® which is walkable within 30-60 minutes and allows for the next coat within 60-180 minutes. Apply it evenly to avoid puddles and ensure full coverage.
3. Floor Levelling
A level floor is critical for a uniform and smooth surface. Use a floor leveller like PCI USP 32® which is walkable in 3 hours and suitable for a range of substrates. Mix it to the correct consistency and apply it evenly, de-aerating with a spiked roller to remove any air pockets.
4. Tanking
The tanking process involves applying a liquid coating such as PCI Lastogum® that bonds to the damp masonry and cures to form a waterproof barrier. It’s crucial for protecting moisture-sensitive areas and should be applied in at least two layers for optimal effectiveness.
5. Waterproof Membrane
A waterproof membrane acts as the primary protection against moisture. It should be applied over all connections and gaps in the shower area. Products like PCI Pecitape® are ideal for this purpose, ensuring impermeability to water and resistance to environmental factors.
6. Tile Adhesive
Tile adhesive like PCI Nanolight® securely holds tiles to floors and walls. It’s versatile for different types of coverings and substrates, and its walkability within 8 hours makes it a practical choice for fast-paced installations.
7. Grout
Grout, a fluid form of concrete, fills gaps and seals joints between tiles. A premium product like PCI Nanofug® Premium® is suitable for a variety of conditions, dries in 40 minutes, and is walkable in 2 hours.
8. Joint Sealant
Sealants like PCI Silcofug® are used for sealing corner joints and preventing water ingress. It’s compatible with a range of materials, skins over in about 10-15 minutes, and cures at a rate of 2mm per day.
Final Thoughts on Shower Waterproofing
In concluding our guide on creating a watertight shower, it’s important to recognize the significance of each step in the waterproofing process. Meticulous preparation, careful application of primers and membranes, and diligent sealing and grouting all contribute to a shower space that’s not just functional but a well-protected retreat against moisture.
The intricacies of waterproofing are numerous, and attention to detail cannot be overstated. A shower that has been properly waterproofed is a shield against the potential damages of water infiltration, such as mold, mildew, and the costly repairs associated with water damage. It’s a proactive step that ensures the longevity and durability of your bathroom, providing peace of mind that extends far beyond the surface of the tiles.
