Creating a wet room is an excellent way to add value to your property while providing a sleek and practical solution for modern bathrooms. However, ensuring a smooth and waterproof surface is crucial to the success of a wet room, and this is where screeding comes into play.
In this blog, we explore the various screeding options available for wet rooms and their suitability for your project.
What is Screeding?
Screeding is the process of applying a smooth, level layer of material over a subfloor to provide a solid foundation for your chosen flooring. In wet rooms, screeding also plays a key role in creating a gradient for water drainage and ensuring the floor is waterproof.
Key Considerations for Wet Room Screeding
When selecting a screed for your wet room, consider the following:
Moisture Resistance: The screed must withstand constant exposure to water.
Durability: Wet rooms experience heavy use, so the screed must be robust.
Gradient Formation: Proper drainage relies on the screed creating an even slope towards the drain.
Compatibility: Ensure the screed works well with your chosen waterproofing system and floor finish.
Types of Screeds for Wet Rooms
Here are the most common screeding options for wet rooms:
Traditional Sand and Cement Screed
Overview: A mixture of sharp sand and cement, this screed is one of the most widely used options.
Benefits: Affordable, widely available, and robust.
Drawbacks: Requires expert installation to achieve the correct gradient and can take several weeks to dry fully.
Best For: Projects with sufficient drying time and budget constraints.
Liquid Screed
Overview: Also known as self-levelling screed, this is a free-flowing compound that creates a perfectly level surface.
Benefits: Fast application, quick drying, and excellent for underfloor heating.
Drawbacks: May require additional preparation for waterproofing.
Best For: Large or irregularly shaped wet rooms, particularly those with underfloor heating.
Polymer-Modified Screed
Overview: This screed includes polymers that enhance its strength and flexibility.
Benefits: Superior water resistance, quick drying, and high durability.
Drawbacks: Higher cost compared to traditional screeds.
Best For: High-traffic wet rooms or those in commercial properties.
Fast-Drying Screed
Overview: Designed for projects with tight timelines, this screed sets and cures rapidly.
Benefits: Reduces waiting time before floor finishing can begin.
Drawbacks: Slightly higher cost and requires precise application.
Best For: Time-sensitive projects or renovations.
Fibre-Reinforced Screed
Overview: Incorporates fibres to improve the screed’s tensile strength and reduce cracking.
Benefits: Enhanced durability and resistance to movement.
Drawbacks: Typically more expensive than standard screeds.
Best For: Areas prone to heavy use or structural movement.
Preparing for Wet Room Screeding
Before screeding, it’s essential to:
Install Waterproof Membranes: These protect the subfloor from water damage and prevent leaks.
Plan the Gradient: Work with a professional to ensure proper water flow to the drain.
Ensure Surface Readiness: The subfloor should be clean, dry, and free of debris.
