The final, yet essential stage prior to decorating, is sealing.

A traditional skimming plaster finish provides a surface ready to be decorated and is an alternative to GTEC Taping and Jointing in certain applications. It is particularly suitable where the quality of board installation is poor, as it will cover surface imperfections, and where drying out time is not important.

There are a number of GTEC boards which can be decorated without plastering, by using a pre-treatment with a bonding agent such as Siniat Universal Sealer, these are:

  • Moisture Board  
  • Fire MR Board
  • Fire Core Board 
  • Acoustic Homespan MR 
  • LaDura Board

*Aqua Board and Render Board should not be plastered as it adversely affects the board's performance properties.
