|Penetrating Seal: CRETEsealers has applied densifiers/hardeners to commercial environments in the Southeast that require a penetrating seal for the purpose of dust proofing the concrete and providing a more sanitary environment. These seals have the added benefit of penetrating into the concrete to harden the top layer. Because the seal penetrates into the concrete, it does not peel or wear and comes with a 20 warranty. This is a low cost method of sealing the floor,
reducing concrete dust, and preserving the concrete and HVAC systems.
