The Natural Building Centre

Y Ganolfan Adeiladu Naturiol.


The interest in natural and traditional building materials has grown enormously in recent years, with more people turning to sustainable, alternatives to conventional building materials. We are stockists of lime plasters and mortars, natural insulation products and breathable paints.

Naturally Hydraulic lime (NHL)

Naturally Hydraulic lime sets harder and quicker than lime putty and is usually used externally as a more robust lime to cope with the weather, or where you need greater compressive strength. NHL comes in three different strengths, NHL 2 NHL3.5 and NHL5, NHL 5 being the hardest.

Lime Plasters

We sell a range of pre-mixed lime plasters ranging from the traditional haired scratch coats to the recently developed hemp and cork insulating lime plasters.

Lime Putty

Pure limestone burnt and then slaked into a putty. Traditionally used for thousands of years and the base ingredient of many of our products. It makes a soft and very breathable mortar which should be used in sheltered locations or internally.
