Siloxane and silane compounds, such as those found on the referenced Xiameter page, can be effective for sealing concrete, but their effectiveness largely depends on the porosity of the concrete. These compounds act as water repellents and pore blockers, preventing the entry of water, oil stains, and paint. However, high-quality concrete with minimal porosity may not benefit significantly from these sealants. Additionally, due to their toxicity, strict safety measures are essential during application, especially in enclosed spaces. For more detailed information on their use in concrete sealing, resources like Ask the Builder provide further insights.
