3. Siliconate Sealers (densifier: HD 7939) – Like silicate sealers, these sealers work by creating a permanent chemical change in the concrete, forming a new, sealed chemistry. Siliconates have larger molecules and offer more surface protection. Siliconates are fast reactive when they meet the concrete therefore remaining at the top of the substrate. Siliconate sealers are the perfect choice when your primary objectives are reducing moisture absorption, reducing freeze/thaw damage and stain penetration. Siliconates dry within the concrete, thereby not changing the appearance or the texture of the concrete surface. They can also be used as a cure for freshly poured concrete. They cure by retarding moisture but still allow the concrete to breath. Siliconates have multiple applications – they can be used on bare concrete walls or stucco to keep moisture from soaking through paint and to allow the paint to last longer. Siliconates can be used on sidewalks, driveways, parking lots, etc. to reduce cracking, staining, and freeze/thaw damage. Overall, this is the sealer we believe works the best for the majority of applications on broom finish or trowel finish concrete.
