Below you’ll find all of the information needed to complete wall lining, partition, floor and ceiling systems, no matter the size and complexity of the project specification.
Does water damaged plasterboard need to be replaced?
Generally yes, the board should be removed and replaced with an equivalent Gyproc product to maintain the original performance criteria.
This would certainly be the case where boards can be seen to be ‘bowed’, suffering with mould growth or where paper de-lamination has occurred. Other instances such as surface wetting, which may dry out relatively quickly, could still develop water stains or mould requiring remedial treatment/action at a later stage of the project.
Plastering on existing painted walls is only possible if the paint and the substrate in which the paint is applied are both in very good condition.
In terms of adhesion and cleanliness, and with the application of Thistle Bond-it prior to plastering. We suggest carrying out this procedure on a trial area to determine the suitability (adhesion).
What is the fire resistance performance of Gyproc plasterboard?
Fire resistance performance is based on complete ‘elements’ such as a partition, wall, ceiling membrane or floor, rather than the individual plasterboards that only form part of these constructions.
Yes, it is possible to tile directly to our Gyproc moisture resistant (MR) grade boards without any pre-treatment, following the tile adhesive manufacturers guidance.
