well Tape and joint is the process of smoothing the joint between two sheets of plasterboard it involves covering and reinforcing the seams between sheets of plasterboard whether on a wall or ceiling.
This method: To prepare a freshly plaster-boarded wall ready for decoration and is used as an inexpensive alternative to skim coating, where the entire surface of the plasterboard is covered with a thin layer of plaster also known as plastering.
The process: joint tape is used to bridge the gaps between two sheets of plasterboard. This can be easily purchased from Wickes or B&Q
The tape is then covered in jointing compound, this strengthens the plasterboard joints and prevent cracking appearing later. This is applied using layers of jointing compound which are then applied with a knife or trowel to create a seamless finish ready for painting or wallpapering.
So a final skim coat of plaster is not required to plasterboard that has been taped and jointed. As a result, it is important that the jointing compound is blended into the surface of the wall to ensure that the joints are flush with the surface of the plasterboard.
This is achieved through a process known as ‘feathering’.
What is feathering?
Feathering involves blending each coat of compound into the plasterboard to make the joint disappear and create a smooth finish.
The jointing compound is moved away from the centre of the joint using taping knives of various sizes until it seamlessly merges with the surface of the plasterboard.
