Clean, stable surfaces are essential. Failing to remove dirt, algae, or loose paint can prevent proper adhesion. Always wash down with a mild biocide and repair cracks before spraying.
Spray cork should be applied in **two to three thin coats**. Applying too thickly can cause sagging or slow curing; too thinly may reduce durability. Follow manufacturer guidance on coverage rates.
Never apply in rain, high humidity, or temperatures below 5°C. Moisture and cold can interfere with bonding and curing, leading to poor results.
Primer ensures adhesion on difficult surfaces. Always mix products according to instructions — incorrect ratios can affect flexibility and finish quality.
Untrained applicators risk inconsistent thickness, uneven texture, and wasted material. Investing in professional training ensures reliable, high-quality results. Join a Spray Cork Training Course.
