General Guidelines

High humidity and non-absorbent substrates will increase setting time.

Plaster benefits from working and compression with steel float. Lime is a caustic material with abrasive mineral components,

take care to protect finished surface from lime staining and scratching by covering and/or cleaning as work progresses.

In renovation work mineral staining may sometimes occur. In this unlikely event consult a painting expert to achieve a breathable finish.

In renovation work, strip non-breathable renders from wall, rake out non breathable pointing, provide adequate drainage around building and ensure breathable floor is installed to avoid forced migration of rising damp in walls. Where adequate steps have been taken allow time for walls to gradually dry out.

 

Do not use in damp basements.
