Secil - Natural Hydraulic Lime (NHL)

£14.00  Price includes VAT


Product Description

NHL (Natural Hydraulic Lime) is made from limestone which contains naturally occurring impurities.
These impurities aid the setting time and hardness of the lime.

NHL will set in the presence of water, so it offers the ideal lime product for use in exposed areas.

NHL Lime comes in different grades, numbered according to hardness (the higher the number, the harder the finish). However, as the hardness increases, porosity and flexibility decrease so it is important to choose the correct product and mix ratio for the application.

This lime is sourced from Portugal by Secil who have been mining lime for generations.

Full pallets of NHL 3.5 and 5 contain 40 x 25kg bags

**Please note. Due to it's low density, NHL 2 is packed in 20kg bags. The bag volume is the same as the NHL 5 and NHL 3.5. 
*There are 50 x 20kg bags to a pallet of NHL 2
