What You’ll Need

• “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer: Prepares porous surfaces for resin application.
• “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm: Delivers a scratch-resistant, glossy topcoat.
• “EpoxyWood” – Wood Restoration Epoxy Resin for Deep Penetration and Waterproofing: Restores and waterproofs damaged or porous timber steps.
• Resin & Paint Application Rollers – Short-Pile, Large, and Sponge Types: Enables smooth, uniform resin coverage.
• Protective gloves, dust mask, mixing container, masking tape, and sandpaper.

Step 1: Prepare the Stair Surface

Ensure the stairs are dry, clean, and dust-free. Begin by sweeping away loose debris and dirt. Follow up with a vacuum and, if needed, a damp mop, ensuring the surface is thoroughly dry before proceeding.

For timber stairs, check for damaged or rotting spots. Sand the surface lightly to remove old finishes and to smooth rough edges. Repair cracks or holes so the resin forms a flawless bond.

Use a suitable primer if applying resin to porous surfaces like bare concrete or timber. Epoxyprimer is ideal for this purpose, delivering proper adhesion and durability for both new and previously uncoated stairs. Allow the primer to cure following the manufacturer’s guidelines, usually 24–48 hours.

Step 2: Restore and Protect Timber (If Needed)

If your stairs are wooden and show signs of wear, water damage, or softness, consider reinforcing them before applying a resin topcoat. Addressing these vulnerabilities ensures your finish remains robust and long-lasting.

Apply a penetrating resin such as EpoxyWood to deeply saturate, strengthen, and waterproof the wood fibres beneath the surface. This is especially important for exterior staircases or stairs subject to high foot traffic and moisture changes.

Let the restorative resin cure fully before progressing to your main epoxy resin coat.

Step 3: Mix and Apply the Epoxy Resin

Mix your resin carefully according to the manufacturer’s instructions. Always work with precise ratios and only as much resin as you can apply within its pot life to avoid premature curing or waste. Stir gently but thoroughly for several minutes until the blend is uniform.

Apply the resin evenly using a roller or brush. Use tools such as the Resin & Paint Application Rollers to distribute the material smoothly and consistently, reaching edges and corners. Start at the top of the stairs and work downwards to prevent trapping yourself.

Allow each resin layer to cure fully between coats. For deep colour or added durability, you may apply a second layer after the first has set according to product guidelines.

Step 4: Finishing Touches and Curing

Once the final resin layer is applied, protect the stairs from dust and foot traffic. Allow for the full recommended curing period—typically 24 to 72 hours depending on temperature and humidity—for a hard, glossy surface that’s ready for everyday use.

For added slip-resistance, you can add non-slip granules or lightly broadcast fine sand onto the wet resin layer if the staircase is in a high-traffic or damp environment.

Carefully remove any masking tape before the resin fully hardens to ensure crisp, clean lines at step edges.

Tips and Common Mistakes to Avoid

Work in a dust-free, well-ventilated environment. Dust contamination is a common cause of rough surfaces and blemishes in resin finishes. Always wear protective gloves and a dust mask for your safety.

Address unevenness immediately and avoid overworking the resin. Use a torch or heat gun for a few seconds to remove air bubbles if needed, but avoid excessive heat. Watch for runs or thick spots on risers and promptly smooth them out.

Avoid rushing between coats—proper curing time gives long-lasting results. If using primer or restorative products, never skip manufacturer-recommended wait times.
