On application it saturates into the substrate, filling internal voids and coating the pore walls throughout the matrix — leaving a slight surface sheen that confirms full penetration. Unlike surface-only coatings, the protection is built into the material itself.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAvailable in 5L, 10L and 20L.\u003c\/strong\u003e\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow It Works\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe three-component chemistry — polyester polymer, polyurethane and acrylic — works together once the water carrier evaporates. The polymer chains deposit throughout the pore structure, the polyurethane adds flexibility and bond strength to the coated surfaces, and the acrylic component locks the system together. The result is a treated matrix that repels moisture at the point of entry rather than relying on a surface film to do the work.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSG: 1.10 @ 20°C | Viscosity: water-like | Solids by weight: 19% | pH: 6.8 | VOC: 66.43 g\/L\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCoverage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e4–5 m² per litre, depending on surface roughness and porosity.
