What Surface Preparation is Needed for Resin on Bricks?

Why Preparation Matters

Surface preparation is the foundation of any successful resin application on brick. Bricks are naturally porous and can harbour dust, old paint, or moisture, all of which undermine resin bonding. By thoroughly preparing the surface, you help the resin adhere evenly and extend the longevity of the finish, whether you’re coating interior feature walls or bathroom brickwork.

Step-by-Step Surface Preparation

• Clean thoroughly: Remove any dust, dirt and grease using a stiff brush and a mild detergent. Allow the brickwork to dry fully before moving to the next step.
• Repair imperfections: Fill cracks or holes with a compatible filler and let it set. Smooth out any rough or damaged patches to achieve an even surface.
• Dry completely: Moisture is a common cause of failure in resin coatings. Ensure the bricks are bone-dry; use a dehumidifier in humid areas, or allow extra drying time in cool conditions.

If you plan to use a product like the “Vertical Glass” resin decorative wall coating, the above steps are even more crucial since the resin is designed for vertical and non-porous applications where proper sealing is required.

When This Matters Most

Meticulous cleaning and drying is particularly important in bathrooms, kitchens, or other humid spots where trapped moisture could compromise the resin’s finish. For feature walls or decorative projects, good preparation helps maintain crisp lines and preserves intricate designs.
