Building maintenance staff, contractors, and facilities teams working on masonry, plaster, mortar, whitewashing, and surface disinfection projects rely on hydrated lime as a foundational material that has been trusted in construction and building maintenance for centuries. This 50 lb. bag of hydrated lime (calcium hydroxide) is a fine white powder ready for immediate use -- no slaking required -- that raises surface and soil pH, disinfects surfaces, improves mortar workability and plasticity, and serves as a key ingredient in stucco, plaster, and whitewash formulations across a wide range of commercial and residential maintenance applications.
Key Features:
- Fully Hydrated -- Ready to Use -- Fully hydrated calcium hydroxide requires no additional slaking -- ready to mix and apply directly to mortar, plaster, whitewash, and surface treatment applications without special preparation equipment.
- High pH -- Strong Disinfectant & Alkali -- Achieves a pH of approximately 12.4 in solution -- highly alkaline chemistry provides effective surface disinfection, odor neutralization, and pH correction in building maintenance and agricultural applications.
- Improves Mortar Workability & Plasticity -- When blended with portland cement and sand, hydrated lime improves mortar plasticity, water retention, and long-term durability -- produces superior mortar performance in masonry and repointing applications.
- Whitewashing & Surface Disinfection -- Mixed with water to form milk of lime, it is applied as a whitewash to concrete, masonry, and block surfaces for disinfection and protective coating in utility spaces, parking garages, and maintenance areas.
- Neutralizes Acids & Odors -- Alkaline chemistry neutralizes acidic soils, concrete surfaces, and organic odors -- effective for pH correction in drainage areas, compactor rooms, and utility spaces.
- Fine White Powder -- Easy to Mix -- Fine-ground powder mixes evenly into water, mortar, and plaster formulations without clumping or uneven distribution.
Where to Use:
- Masonry and repointing work -- Blended with portland cement and sand for mortar in brick, block, and stone masonry repairs and repointing in commercial and residential building maintenance
- Whitewashing and surface disinfection -- Mixed with water for whitewash application on concrete floors, block walls, utility rooms, parking garages, and compactor areas
- Plaster and stucco applications -- As a plasticizing and binding ingredient in interior and exterior plaster and stucco formulations for building renovation and repair
- Odor and pH control -- Neutralizing acidic conditions, organic odors, and surface contamination in utility areas, drainage channels, and compactor rooms of managed commercial and residential properties
