How Much Resin Is Needed for an Average Staircase?

Average Quantity Needed

Most typical residential staircases require between 2kg and 10kg of resin for resurfacing, but the amount will vary based on staircase dimensions, the condition of the substrate, and the thickness of the layer applied. Straight flights with 10–15 treads are usually at the lower end of this range, while larger or wider stairs, or those with landings, will push the total up.

How to Estimate Resin Coverage

Coverage depends on resin type and application thickness. For example, clear epoxies such as “Trasparente” generally cover 1–2m² per kg at around 1mm thickness. Always refer to the manufacturer’s guidelines for specific product coverage, factoring in extra resin for edges, risers, and any filling required for imperfections.

• Measure total surface area including treads, risers, and sides if needed.
• Decide on layer thickness (usually 1–2mm for stair treads).
• Multiply area by thickness and check against the chosen resin’s coverage data.

Selecting the Right Resin for Your Stairs

The substrate and finish you want should inform your resin selection. “Resinstone” is suitable for concrete stairs and offers hard-wearing, breathable sealing, while clear resins such as “Art Pro” are great for decorative top layers. If you are seeking a glossy, transparent look, opt for certified multipurpose epoxies, ensuring you stay within recommended application thicknesses.
