They are typically used in conjunction with Schluter's Ditra membrane for a seamless, waterproof, and structurally sound installation.
Benefits of Schluter Stair Nosing

- Durability: Crafted from high-quality aluminum, Schluter stair nosing is resistant to corrosion, wear, and tear, ensuring longevity and minimal maintenance.
- Versatility: Available in various sizes, colors, and finishes, these nosings can accommodate different stair profiles and complement various design styles.
- Easy Installation: Schluter stair nosing can be installed quickly and easily using standard tools, saving time and labor costs.
- Waterproofing: When used with Ditra membrane, Schluter stair nosing creates a waterproof barrier, preventing moisture-related issues and protecting the substrate beneath.
Installing Schluter Stair Nosing: A Step-by-Step Guide
Before you begin, ensure you have the necessary tools and materials, including Schluter stair nosing, Ditra membrane, thin-set mortar, notched trowel, utility knife, and a saw for cutting the nosing to size.

Preparation
Clean the stair treads and risers, and ensure they are dry and free of debris. If using Ditra membrane, install it according to the manufacturer's instructions before proceeding with the nosing installation.
Marking and Cutting
Mark the position of the nosing on the stair tread, ensuring it is centered and aligned with the riser below. Cut the nosing to the required length using a saw, following the manufacturer's guidelines for cutting aluminum.
Applying Thin-Set Mortar
Using a notched trowel, apply thin-set mortar to the back of the nosing, ensuring full coverage. Also, apply mortar to the stair tread where the nosing will be installed.

Installation
Press the nosing firmly into place, aligning it with the marks made earlier. Ensure the raised edge of the nosing is flush with the edge of the stair tread. Allow the mortar to cure according to the manufacturer's instructions.
Finishing Touches
Once the mortar has cured, apply silicone sealant to the joints between the nosing and the stair tread, as well as any cut edges. This will provide additional protection against moisture and improve the overall appearance.
Schluter Stair Nosing vs. Traditional Methods
| Schluter Stair Nosing | Traditional Methods |
|---|---|
| Preformed metal profile for easy installation | Custom-cut wood or metal nosing, requiring more labor and skill |
| Slip-resistant surface for improved safety | Smooth surface, prone to tripping hazards |
| Durable, corrosion-resistant aluminum | Wood or metal that can rot, rust, or warp over time |
| Waterproof when used with Ditra membrane | Prone to moisture-related issues, such as mold and mildew |
As demonstrated, Schluter stair nosing offers numerous advantages over traditional methods, making it an ideal choice for both residential and commercial projects. Its combination of safety, durability, and ease of installation makes it a popular choice among professionals and DIY enthusiasts alike.
When selecting Schluter stair nosing, consider the specific requirements of your project, such as the size and finish of the nosing, as well as any local building codes or regulations.
