Building Materials

Ty-Mawr Lime Hemp Plaster is made from a high calcium lime (also known as a fat/air/putty Lime or non-hydraulic lime) blended with hemp fibres and a pozzolan to aid the set. Hemp plaster can be bought pre-mixed in three different grades, it has some insulation benefits, but its main benefit is ease of use and labour saving, as it can be applied more thickly than conventional lime plasters.

Ty-Mawr Premixed Lime plaster is a ready-to-use plaster that simply requires 'knocking-up' prior to use. For internal use.

For pointing and building work this mortar is made from aggregates and fat lime putty, pre-mixed and ready to use.
