Exposed Plastering is generally done using 1 cement :3 Fine sand . But mixing some 1 part out of 3 parts coarse sand is beneficial for durability , though specs are for fine sand plaster.
For Plastering on walls needing Tiles finish , plaster shall be from all coarse sand in ratio 1:3.
Before plaster application walls must be watered on face followed by flashing of cement slurry. Also curing of plaster shall be done religiously.
Just a thought for durability. |
