Visual Guide: Tools and Products Needed

Lay out all required tools and material kits before starting your resin installation—this ensures a smooth workflow and prevents costly interruptions. Use safety equipment, and check product labels for best substrate matches.

Step 1: Prepare the Brick Substrate

Begin by ensuring the hollow brick surface is clean, dust-free, and fully dry. Remove any debris, loose particles, or previous coatings that could prevent the resin from bonding effectively. Use a vacuum cleaner, brush, or air blower to access hard-to-reach hollow cavities and remove all dust. If needed, sand lightly to create a rough texture for improved adhesion.

Ensure surfaces are completely dry before coating, as trapped moisture in bricks can hinder curing or cause bubbling in resin applications.

Step 3: Install the Resin-Coated Material

Choose your resin solution based on the final appearance and use-case. For a decorative wall finish or waterproof interior, use a trowel or spatula to apply a resin wall coating directly onto the prepared bricks. Work in thin, even layers to avoid drips on vertical surfaces. For applications involving aggregate mixes—such as creating a permeable or decorative stone layer—fully combine your chosen resin binder with pebbles or grits in a mixing bucket until evenly coated. Then place the mix firmly into or onto the hollow brick surface, pressing into recesses and compacting for void-free installation.

“Vertical Glass” – Thick Resin Decorative Wall Coating is ideal for direct wall applications, offering a customisable, easy-to-clean finish. For outdoor or permeable aggregate projects, consider “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit with white/natural stones, or “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits for vibrant, coloured surfaces.

Avoid excessive resin thickness in single applications; multiple thin layers provide greater control and better curing on vertical or uneven surfaces.

Tips, Common Mistakes, and Troubleshooting

Installing resin-coated materials on hollow bricks requires special care: bricks’ porosity can cause rapid resin absorption, so always check compatibility and plan for potential priming. Take care to fully encapsulate aggregates for cohesive mixes. Be mindful of working time, as resins can set quickly in warm conditions. Mask off adjacent areas to prevent accidental resin spill on unwanted surfaces.

Check resin compatibility with bricks and aggregates before starting your project, especially when mixing stone binders and different substrates.
