Hydrated Lime (Calcium Hydroxide)

Hydrated Lime for Building, Water Treatment and pH Control

Hydrated Lime is a fine white powder of calcium hydroxide. Producers make it by reacting quicklime with a controlled amount of water, a process called slaking. It is a strong, low-cost alkali used in building, water treatment and many industries.

We stock Neelkanth Hydrated Lime from the Neelkanth Group. The bag describes it as high-quality calcium white building lime, packed in 25 kg bags. Wisdo Merchants Chemical Division delivers it across Kenya and East Africa from Industrial Area, Nairobi.

Applications of Hydrated Lime

Building and Construction

Masons add hydrated lime to cement mortars and plasters. It improves workability, water retention and bond, which helps reduce cracking. Builders also use it in limewash and lime plaster. Browse our construction chemicals and adhesives.

Water and Wastewater Treatment

Treatment plants use lime to raise pH, soften water and help remove impurities. It also neutralises acidic effluent. See our water treatment chemicals.

Agriculture and Industry

Farmers use lime to reduce soil acidity, although agricultural lime products are often preferred for large areas. Industries use it in sugar refining, leather tanning and chemical manufacturing. View our agricultural chemicals.

Safety and Handling

• Eye damage: It can cause serious eye damage. Always wear goggles.
• Skin irritation: Wear gloves and long sleeves, especially with wet lime.
• Dust: It irritates the nose and throat. Wear a dust mask.
• First aid: Rinse eyes immediately with plenty of water and seek medical help.

Always read the Safety Data Sheet before use.

Storage and Shelf Life

Store bags in a dry, covered place on pallets. Lime slowly reacts with carbon dioxide in air and loses strength. Therefore, keep bags sealed and use stock in rotation.

Frequently Asked Questions

What is the difference between hydrated lime and quicklime?
Quicklime is calcium oxide and reacts strongly with water. Hydrated lime is quicklime that has already been reacted with water, so it is safer and easier to handle.

Can I add hydrated lime to cement mortar?
Yes. Lime is a traditional addition that improves workability and water retention.

Do you deliver outside Nairobi?
Yes. We deliver across East Africa and confirm freight and timelines with your quotation.
