For underground surfaces, ensure an even coating without air bubbles.\u003c\/p\u003e\n\u003cp\u003eFor best waterproofing results, apply 2 to 3 coats, with each coat applied after the previous one is surface dry. Recommended coverage is approximately 0.2–0.25 kg\/m² for the primer and approximately 0.6 kg\/m² for each topcoat.\u003c\/p\u003e\n\u003ch2\u003eImportant Notes for Use\u003c\/h2\u003e\n\u003cp\u003eAlthough DEFIX DB-1 has excellent waterproofing capabilities, it still needs to be used for its intended purpose to ensure longevity.\u003c\/p\u003e\n\u003cp\u003eAs a water-based product, the membrane is not UV resistant for long periods. Therefore, for exposed areas such as concrete roofs, after completion, an additional protective layer such as heat-reflective paint or a protective mortar layer should be applied.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the product is not designed as a finish layer for direct foot traffic. Once opened, the product should be used completely and not diluted with solvents.
