The short answer is yes—provided you choose the right product.
Not all ready mixed microcements are waterproof. Many decorative microcement systems still require a protective sealer to stop water from penetrating the surface. However, some ready mixed waterproof microcement products are manufactured with waterproof properties built into the coating, making them ideal for bathrooms, wet rooms, showers, and other high-moisture areas.
What Is Ready Mixed Waterproof Microcement?
Ready mixed waterproof microcement is a pre-blended coating that arrives ready to use, eliminating the need to measure or mix powders. This makes installation faster, cleaner, and more consistent.
Unlike traditional microcement systems, waterproof versions are specifically designed to resist water penetration while maintaining the seamless, concrete-effect finish that makes microcement so popular.
Where Can It Be Used?
A waterproof ready mixed microcement can be applied in a wide range of areas, including:
- Showers
- Wet rooms
- Bathrooms
- Kitchen splashbacks
- Kitchen worktops
- Floors
- Walls
- Commercial interiors
Because it creates a seamless surface with no grout joints, it is easier to clean and helps reduce areas where dirt and mould can accumulate.
Does It Still Need a Sealer?
That depends on the product.
Some ready mixed waterproof microcements are designed to be waterproof before sealing, while others rely on a high-performance sealer to provide complete water resistance. Even when the coating itself is waterproof, manufacturers often recommend a sealer because it:
- Protects against stains.
- Improves scratch resistance.
- Makes cleaning easier.
- Extends the life of the finish.
- Can provide a matt, satin, or gloss appearance.
Always follow the manufacturer’s installation guidelines to achieve the best performance.
Is It Suitable for Showers?
Yes. A high-quality ready mixed waterproof microcement is an excellent choice for shower walls and floors when installed correctly.
The seamless finish means there are no grout lines to maintain, while the waterproof surface helps prevent moisture from reaching the substrate. For shower floors, an anti-slip finish should be used to improve safety.

Final Thoughts
Ready mixed microcement can be waterproof, but it is important to choose a system specifically designed for wet environments. If you are installing microcement in a shower, wet room, or bathroom, look for a product that is marketed as waterproof and install it according to the manufacturer’s instructions. Adding the recommended sealer will also improve durability, stain resistance, and long-term performance.
