Stone Amor Penetrator Pro is a deep penetrating, clear and breathable water repellent, stone sealer, concrete sealer and consolidator. It is suited for protecting calcareous and porous stones such as limestone, travertine, flagstone, and marble. It is also suited for concrete that has a high percentage of limestone or coral aggregate, pavers, and low-fired clay products (roofing tiles, brick, terracotta, floor tiles). It is designed to increase the life of patios, decks, pool coping, spas, waterfalls, grout, walkways, showers, landscape stones and more. This VOC free proprietary siliconate technology is a single-step process that prevents water and contaminants from entering the substrate and causing deterioration and damage. It reduces efflorescence, spalling, leaching, scale, deicer scaling, staining, acid rain deterioration, dirt build up and corrosion. Penetrator Pro also contains consolidation technology for binding loose or powdery surfaces making them much stronger and giving the ability to withstand degradation due to freeze thaw and weathering.
