Thorough surface preparation is essential for creating a beautiful and durable resin wall niche. Whether your base is tile, cement, wood, or brick, the right groundwork ensures the resin adheres smoothly and lasts.
Cleaning and Priming the Surface
Begin by removing dust, grease, mould, and any loose material from the niche area. Clean with a mild detergent and allow the surface to dry completely. If repairing old finishes, sand lightly to create a key for the resin. For absorbent backgrounds such as brick or cement, applying a primer will help minimise absorption and promote even coverage.
Repairing and Levelling
Fill any holes, cracks, or uneven patches using a suitable filler or repair compound. Sand these areas once dry, then wipe away dust. A flat, stable foundation is vital for achieving a professional result, particularly as decorative resins like Vertical Glass do not self-level and will preserve any surface irregularities found beneath.
Guidance for Different Substrates
- Tiles: Degrease and sand gently to allow resin to bond.
- Cement & Brick: Ensure all loose particles are removed and prime to stabilise the surface.
- Wood: Check for moisture content and seal knots to prevent future staining or movement.
Always ensure your surface is dry, dust-free, and firm before resin application.
When Proper Preparation Matters
Meticulous preparation makes a significant difference in high-moisture areas or where sharp design detailing is key. It prevents peeling, bubbling, and uneven finishes, especially when using resins intended for vertical and sloping surfaces in bathrooms or kitchens.
