SO WHAT IS GYPSUM ??
HOW DO THEY MAKE PLASTER AND PLASTERBOARDS ?
ROCK IS TAKEN FROM THE GROUND USING THE LATEST ‘DOSCO’ MINING EQUIPMENT
HOW DOES IT START ?
HOW DOES IT START ?
THE CRUSHED ROCK TO MAKE PLASTER IS TRANSFERRED TO THE HOMOGENISER WHERE ITS GRADED AND SORTED
HAVING BEEN TRANSPORTED TOTHE SURFACE THE ROCK IS CRUSHED,COMBINED WITH DIFFERENT ADDITIVES AND MIXED IN CONICAL KETTLES PRIOR TO PLASTERBOARD AND PLASTER PRODUCTION
HOW DOES IT START ?
THE PRE MIXED SLURRY IS PUMPED ONTO PAPER LINER TO START THE PLASTERBOARD MAKING PROCESS
IN THE EARLY STAGES OF PRODUCTION A PLASTERBOARD HAS A CONTINUOUS LENGTH OF APPROX. ½ MILE

The History of Plastering
HISTORY
•LIME PLASTERING•A mixture of sand, lime & hair.•Site mixed.•Lime pit on site.•Piles of sand on site•Large area required•DANGEROUS working area - personnel
Sand &Cement
•A mixture of sand & cement - with or without a plasterciser.or Retarders.•For use inside or outside.•Ready mixed or Site mixed.•Prone to Shrinkage & Cracking•Large variation in quality & consistency•Large area required for mixing /delivery.•Can not work in frosty conditions
THISTLE PLASTERING
• Lightweight in use• Pre-blended in bags• Consistent Quality• Full Range of products• Ease of use and installation• Continuity of work, even in
winter months• User friendly [area required for
mixing]• Productivity, More profit • Safer working environment
PRODUCT RANGE
PLASTER
• Provide a smooth, high quality surface for internal walls and ceilings
• Provide a durable base for the application of decorative finishes
• Benefit from the excellent fire protection properties of gypsum
• Range covers two-coat plastering using an undercoat & finish, finish coat plastering and special applications such as X-ray protection
• Plasters are pre-mixed and only require the addition of clean water

BACKGROUNDS TYPES
• Solid
• Concrete
• Plasterboards
• E.m.l
• Bonding agents
• Other elements
Masonry,brick,block
Pre-cast. In situ .
M.R. or Standard liner
Rib lath or eml sheets
Thistlebond- it, PVA
Bituminous Emulsions
PREPARATION
• Know the backgrounds• Check the work areas• Scaffolding required• Know the products to specify• Mixing areas, water, etc.• Prepare the backgrounds as necessary• Grounds , Linings etc.• Clean ,Dry etc.
Aerated Concrete Blocks
Lightweight blocks usedregularly in housing.
What kind of a key does the background have ??
Smooth ?
Rough ?
Does it require a mechanical key ?
Are they standard concrete block OR
Dense concrete blocks ??
Which Plasters where?•Hardwall Masonry ,blockwork, [low to high suction]
•Bonding Coat Concrete,dense blocks,bonding agents [low suction substrates] eml.Plasterboards
•Browning Masonry/blocks with good key/medium suction
•Tough Coat High use areas, Masonry
Which Plasters where?
Renovating Masonry/blockwork - low/high suction
Dri-Coat Masonry,DPC [replastering]
X Ray masonry/Rib Laths, dense blocks,must have good key.
Projection & Univeral Full range of backings – masonry/ blocks/bonding agents/plasterboards.
Thistle Bond-It
Provides a mechanical key to many smooth surfaces
(e.g Ceramic tiles, cast concrete etc.)
Always roller applied
ThistleBond-itA bonding agent specially formulated
for use on smooth backgrounds.
Contains fine aggregate for better mechanical key.
Achieves chemical adhesion.
Plaster can be applied when the thistle bond - it is dry.
No dilution.
Applied with a heavy pile/texture roller.
Green colour for easier identification.
Thistle Prime
•For the pre-treatment of very high suction backgrounds.
•Dilutes as necessary, giving total flexibility to suit the background concerned.
•Yellow colour for ease of identification.
•Thistle Prime and ThistleBond - it are the only recommended solutions for use with Thistle
Plasters.
Thistle Plasters
• Techniques
– 1 coat / projection (13mm)– 2 / 3 coat (11mm + 2mm)– skim (2mm)
• Factors affecting plaster selection
– environmental– background condition
• clean, dry, reasonably level– background type
• high or low suction– performance requirements
• damp proof courses
Why Thistle Plasters?
Premixed - ready to use
Suitable for a wide range of backgrounds
Consistent setting time
No Shrinkage
