← Back to For tiles, is resin-based or water-based better?


Tiling walls or slopes often calls for more than just good adhesion – you need a resin system that won’t drip, will deliver a waterproof layer, and offers a lasting decorative finish. Here’s what you need to know about choosing the right coating for vertical or sloping tiled surfaces.
Why Epoxy-Based Coatings Excel on Vertical Tiles
Specially designed epoxy coatings, such as Vertical Glass, are formulated to cling to tiled and masonry surfaces without sagging or self-levelling. This allows you to build up a uniform, glossy, and waterproof finish, even on angled or vertical walls. The viscosity and working time are tailored for detailed application, enabling you to achieve creative effects while maintaining durability in high-moisture environments like kitchens or bathrooms.


Application Tips and Surface Preparation
Proper preparation is crucial for a long-lasting coating. Before applying an epoxy resin, thoroughly clean tiles to remove grease and residues. For best results, use a suitable primer – for instance, Epoxyprimer – to promote ideal adhesion and stability. When using thick coatings that don’t self-level, apply with a spatula or trowel to control thickness and limit drips. Sanding between coats can help achieve a satin appearance or further improve adhesion.
When This Matters
- Bathrooms, kitchens, and wet rooms: A waterproof resin finish guards against moisture and stains.
- Decorative feature walls or splashbacks: Epoxy’s customisable finish lets you add pigments or metallic effects to vertical surfaces.
- Sloping entries or stair risers: Choose a system that stays in place on angles, for uniform protection and aesthetics.
