Gib Fixer Rules
These are the rules for gib fixing. These rules will guarantee a better finish and a more lasting finish. These are the basic rules to help you find a qualified company for gib stopping in auckland. It will be easier to ask questions and spot errors before you hire them.
gib fixer Rule 1 : Fix gib so that light doesn’t cross joins
The gib plasterboard joints must be sealed to prevent light from passing through them.
This is done by attaching sheets in a direction opposite the main light source. The gib is typically attached horizontally to walls. However, there are some instances when light can be run vertically, such as in skylights or smaller rooms that have darker walls.
Gib fixer rule 2. Reduce the amount of butt and use cut joins
Butt joints are formed when two non-tapering ends meet. Gib is ordered to fit every ceiling and wall. We also order the largest sheet size. This reduces the need for butt joints.
The instructions for sheet layout are followed by our gib fixers. If in doubt, our gib fixer will help you choose the layout.
We reduce butt joints in places where they are not possible by placing them above windows and doors, as long as they comply with gib fixer rules 3 and 4.
It is best to arrange butt joints in ceilings in a stoop.
Wiseman Rule 3: Keep joints clear of areas that are susceptible to movement
These areas are more vulnerable to defects than those that move less, so gib fixers should not join them.
Areas prone to movement include
a) In the corners of doors and windows We recommend keeping joints at least 200mm away from corners to avoid cracking.
b) Junctions in rooms and corridors.
c) Stairwells or mezzanine floors. This area is the most susceptible to plasterboard defects. Because of the length and shape of the timber, these areas are susceptible to defects. You can see any timber shrinkage from a distance. Another place to watch out for is the junctions between floors. These are the places where lateral forces can play when the building settles or moves. The gib fixers stop the formation of joins between floors.
Gib fixer: Rule 4: Back-blocking ceiling joins, and staircases
Back-blocking strengthens and stabilizes the joints between plasterboard sheets. According to New Zealand gib plasterboard standards any ceiling that has three or more joins must be back-blocked. PBF gib fixers backblock ceilings or stairs with more horizontal joins than 2. This decreases the likelihood of timber peaking or expanding.
While some builders and gib fixers might use back-blocking to install back-blocks, most use contact adhesive or standard setting. PBF gib fixers use cove bond, a plaster-based adhesive to attach back-blocks. Although this method is not recommended for gib and other plasterboard manufacturers it is very common. The cove bond is strong and rigid, so it prevents cracking. It keeps pressure off the joint. This information is based on the AS/NZS2589 2007 guidelines for plasterboard (gibboard).
Design Issues
PBF is often faced with design and construction problems that directly impact the reliability and appearance. These problems can lead to cracking and peaking, no matter how hard the gib fixer works.
We recommend speaking with your gib fixing specialist as soon as possible to avoid such problems.
Your gib fixing specialist might point out:
- Timber ceiling battens make a great choice because they can be easily moved.
- Framing not in conformance with NZS3609: 1999
- Framing with too many moisture
- Ceiling batten layout
- Control joins are not being used
