The exterior of the “JamRocKing Marble Lime House” has been renovated with the world’s first carbon negative marble lime wash. The lime wash is made using the rare natural “calcium oxide from marble” that surrounds JamRocKing’s house that is based in the hills of St. Ann, Jamaica. It was developed by our family owned junior mining company, K & B Enterprises Limited. The smooth beautiful luminescent marble lime finish revived our old house and created a more tranquil and comfortable environment. The marble lime wash improves as it sets by absorbing carbon dioxide as it returns to its original stony marble state as part of the natural lime cycle.

My first attempt at sustainable renovation using clay as a paint on our house did not work as the before and after pictures show. The clay also comes from our property that used to be a small cattle farm. My second attempt to sustainably renovate our house is nearing completion. This time I crushed and slaked the natural marble lime that covers many of the hills that surround the JamRocKing house. The marble lime wash is much more pleasing to the eye than my experiment with clay as the pictures show.

JamRocKing’s lime wash is made by crushing our marble lime into a powder and then ‘slaking’ and stirring it in water until it turns into a lime milk, slurry or a smooth ‘Venetian’ like plaster. The longer the marble lime soaks in water the thicker it becomes. The addition of water or hydrogen oxide, H2O, activates JamRocKing’s natural oxides and turns them into some of the best natural carbon dioxide absorbers. These absorbers help make JamRocKing’s marble lime a carbon negative building material. JamRocKing’s marble lime wash is also hydraulic because it absorbs water.

Lime coatings like JamRocKing’s are well suited for tropical or damp climates like the rainy hills of St. Ann because the lime ‘breathes” and allows moisture to evaporate. This helps to save energy because the heat improves as the dampness is removed. The marble lime wash is more waterproof than cement and prohibits moisture, bacteria, mold and mildew from forming within the building envelope. Our marble lime wash does not contain any Volatile Organic Chemicals, VOCs. The only additive is linseed that is added to improve the lime wash’s adhesion and durability.

JamRocKing’s marble lime also contains traces of silicon dioxide, iron oxide, alumina oxide as well as minute traces of pure nickel, pure manganese and pure iron. Some of these minerals are considered rare. JamRocKing’s natural minerals make it the world’s first natural carbon negative marble lime cement.

The deposit’s mineral composition is confirmed in the chemical analysis we received from one of the world’s leading lime companies, Lhoist. Geologists from Lhoist and its parent company, LaFarge, carried out a site visit and collected random samples from JamRocKing’s property. Lhoist discovered the deposit’s traces of pure manganese, iron and nickel. The chemical analysis from Lhoist and Jamaica’s Ministry of Mining are included in the pictures because they confirm that JamRocKing’s marble deposit contains a rare natural marble calcium oxide, CaO.
