1. Direct Bond – Dry Lining to Masonry Backgrounds
Fix Dry Lining and Plasterboard Products to Interiors

2. Direct Bond
Introduction
Dry lining was introduced to speed up the completion of building projects by cutting drying times.
The basic concept is to stick plasterboard to walls using a gypsum based adhesive product, and finish either by skimming with Thistle Finish Plasters or taping and jointing where tapered edge Plasterboard is used.

What do you know?
What type of Gyproc Plasterboards are used in dry lining?
How are the joints reinforced?
What is the minimum thickness of a dab of adhesive?
Where are Gyproc nailable plugs used?
What is the reason for using a parge coat?

4. Direct Bond
Wall Alignment
The first step when direct bonding to a background is to
check the wall is suitable, ie, is the wall stable,
is the wall dry. Then find the high point of the
Wall.

5. Direct Bond
Setting out
Transfer the high point onto the ceiling, add 10mm for adhesive
dab plus thickness of board to be used.
use this point to mark corners of wall and
strike lines on ceiling and floor with a
chalk line.

6. Setting out cont’d Depending on the width of Plasterboard
Direct Bond
Setting out cont’d
Depending on the width of Plasterboard
that is used, mark the position of the
Plasterboards onto the wall with an off cut of
Plasterboard.

7. Gyproc dri-wall adhesive

Gyproc dri-wall adhesive
Gypsum Based Adhesive for Plasterboards
and Gyproc ThermaLine boards.
Suitable for high, medium or low suction
backgrounds
Supplied in 25 Kg sacks
Coverage for a 25kg is 6m2 of board
(2 boards per bag)

8. Applying adhesive A full bead of adhesive should be placed

Applying adhesive
A full bead of adhesive should be placed
at all wall intersections and around any
openings doors windows etc.
This should included any cut
outs in the boards for
services

10. Application of adhesive
Direct Bond
Application of adhesive
Trowel apply adhesive to form dabs
50mm to 75mm wide and about 250mm
long.
Apply the adhesive in three vertical rows
to receive the first board.

11. Positioning boards Cut plasterboard 15mm short of the
Direct Bond
Positioning boards
Cut plasterboard 15mm short of the
floor to ceiling height.

12. Positioning boards cont’d

Positioning boards cont’d
Tap the board back firmly using a straight-edge
until it aligns with the ceiling and floor
chalk lines.

13. Positioning boards cont’d
Direct Bond
Positioning boards cont’d
Gently lift using a footlifter until the board
is tight against the ceiling and place
packers under board to wedge in place.
Apply dabs for the next plasterboard
and continue the dry-lining with boards
lightly butted.
