Plaster / Render


Render

Render is 3 parts sand mixed with 1 part cement.
Plasticizer and waterproofing agent added to create a waterproof layer for exterior applications.

Plaster

Plaster contains gypsum and is for internal applications only, as moisture will cause it to crumble.
old fashioned form of plaster is Lime plaster where the binding gypsum is replaced with lime.


Weight of plaster required (Kg) = ( Plaster Area(m2) x Plaster Thickness(mm) )/ 1.5
