What You’ll Need

• “Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways: For sealing and protecting concrete stair surfaces.
• “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm: To achieve a glossy, tough and crystal-clear finish on interior staircases.
• Resin & Paint Application Rollers – Short-Pile, Large, and Sponge Types: For easy, even resin distribution over both treads and risers.
• “Jacquard Pinata” – Alcohol Ink Blast Effect 14ml: Optional, to create vibrant decorative effects or colour accents within resin layers.
• Protective gloves, mask, masking tape, cleaning solutions, sandpaper, and a mixing container.

Step 2: Prime and Seal the Surface

Priming minimises dust, strengthens the bond and ensures an even coat. On concrete stairs, use “Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways as your base layer. Use a roller for thin, uniform application, working from the top stair downwards. Apply masking tape along adjoining areas to prevent accidental over-rolling onto neighbouring finishes.

Let the primer/sealant dry thoroughly—usually a few hours, but always check the product’s instructions for specific guidance. This stage is essential to prevent trapped moisture and to provide an optimum surface for the resin top coat.

Step 4: Build Up Layers and Add Decorative Effects

Pour or roll the resin evenly starting from the top step and progressing downwards for each new coat. Work swiftly to maintain a wet edge between steps and reduce mark lines. If bubbles appear, remove air bubbles using a spike roller or heat gun if required before curing begins.

For a personal touch, you may wish to add colour or artistic effects to the resin. “Jacquard Pinata” – Alcohol Ink Blast Effect 14ml delivers intense, transparent hues and can be used sparingly within the still-wet resin for vibrant highlights or intricate veining.

Allow each layer to dry before applying another. Add a second coat for enhanced durability if the stairs will see heavy foot traffic or require a particularly glossy finish.

Tips, Common Mistakes and Troubleshooting

Patience during prep pays off—thoroughly cleaning and masking will prevent defects later. Avoid pouring overly thick resin layers at once, which can lead to bubbles and uneven curing. Always ventilate well, mix products as instructed, and use the right roller type for the job. Sand between coats for superior adhesion and finish. If bubbles persist, use a spike roller or light heat (but not open flames). For slippery surfaces, always include anti-slip measures. Address any unevenness by sanding and recoating only when previous layers are fully set.
