Chalkhill (Hot) Lime Mortar

£7.25 (inc VAT £8.70 )

Hot Lime mortars are non-hydraulic, mortars perfect for pointing and building with softer stones, and bricks.

The softer mortar has a higher porosity, and better flexibility than hydraulic mortar, as is relies solely on natural carbonation.

These come pre-mixed wet, and ready to use, all you need to do is rework them.

You can also turn these into a hydraulic mortar by the addition of a pozzolan. This then turns the mortar to an FHL

(Formulated hydraulic lime) as oppose to an NHL (natural hydraulic lime)

The use of FHL has been around since the Romans who used volcanic ash to formulate the lime when building the colosseum, this adds extra strength to the mortar, but does slightly lower the breathability, and flexibility. By increasing the amount of pozzolan added to the mortar will increase the mortars strength, and breathability. This enables you to use the same mortar for several different applications where the strength, and a better weather resistance is needed.
