What are your recommendations?


  • We recommend back-blocking all ceilings.
  • Blocking external walls where insulation has been installed.
  • Using screws rather than nails
  • Using cement sheet where tiles will be installed.


  • Our practice is to use three coats of plaster on most joins.
  • When joining new to existing, we use as many coats required to lessen the appearance of that join.


  • When it comes to cornicing, there are a wide range of finishes.
  • Simple scotia cornices
  • Square set
  • Shadowline
  • Large plaster cornices

We recommend using a cornice that best suits the style and period of your project. In the end, however, it all comes down to personal tastes.

Should I batten ceilings or direct-fix to trusses?

We recommend battening. Battening strengthens and braces trusses- lessening movement and stress on plasterboard ceilings. This decreases the chance of popping screws or plaster cracking.

Why do I see plaster joins at certain times, but not others?

Plasterboard is not a perfect product. Plasterboard has a paper (therefore textured) finish, while the plaster used to fill joins has a smooth finish. The join you can see at certain times is a result of the light highlighting different textures. Australian Standards requires a Level 4 finish. In certain circumstances where we feel that light may be an issue, for example, a skylight, we will achieve a Level 5 finish. This will eliminate the difference in textures as the entire area of plasterboard is coated.
