Apply Resin Only When Bricks Are Completely Dry

Why Dry Bricks Matter for Resin Application

Resin coatings need a stable, dry substrate to adhere properly. If bricks contain moisture, the resin can struggle to bond, leading to peeling, bubbles, or discolouration. This is particularly crucial for vertical surfaces where gravity and humidity can further challenge adhesion and finish quality. Waiting until bricks are completely dry safeguards the final result and maximises the protective benefits of the resin.

How to Ensure Bricks Are Dry Enough

• Timing: Allow bricks to dry out naturally for several days if they’ve been recently washed, rained on, or exposed to high humidity. The surface should not feel cool or damp to the touch.
• Environment: Apply resin in dry, mild weather with good air circulation. Avoid days with rain, fog, or very high humidity.
• Testing: Tape a small square of plastic to the brick and leave it for a few hours. If condensation forms underneath, more drying time is required.

Best Practices for Applying Resin on Brick Walls

Once you’ve confirmed the bricks are dry, remove dust and debris before coating. For product recommendations, “Vertical Glass” – Thick Resin Decorative Wall Coating is well-suited to vertical and sloping brick surfaces and can be applied with a spatula. Follow manufacturer guidance for mixing, application thickness, and curing times to secure an even, resilient finish.
