A composition that may be used to retain moisture within fresh concrete as it cures to optimize the curing of the concrete may include one or more hardening and densifying agents (e.g., alkali metal polysilicate, colloidal silica, etc.) and one or more temporary moisture sealing agents (e.g., a wax, etc.). Additionally, such a composition may include a siliconate (e.g., a metal siliconate, such as an alkali metal siliconate like potassium methyl siliconate, etc.). The hardening and densifying agent of such a composition may penetrate the surface of fresh concrete to react with free lime, providing the fresh concrete with a strong surface. The temporary moisture sealing agent may form a moisture barrier on the surface of the fresh concrete to prevent moisture from escaping from the fresh concrete (e.g., evaporating, etc.) before the fresh concrete has sufficiently cured. The temporary moisture sealing agent may degrade within a matter of days (e.g., three days, seven days, 14 days, less than a month, etc.), facilitating its removal from the surface of the concrete once the concrete has cured and enabling further treatment of the surface without undue delay.

The PVC drywall board is configured for use in construction. The PVC drywall board is used to form a non-load bearing surface in a structure under construction. The PVC drywall board is intended to replace traditional drywall. The PVC drywall board is a flexible structure. The flexible structure of the PVC drywall board allows the PVC drywall board to be stored as a scroll before the deployment of the PVC drywall board for installation as a non-load bearing surface of the structure under construction. The PVC drywall board includes a kerf bending, a textured coating, and a barrier structure. The textured coating is sandwiched between the kerf bending and the barrier structure.
