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 ?
THE CRUSHED ROCK TO MAKE PLASTER IS TRANSFERRED TO THE HOMOGENISER WHERE ITS GRADED AND SORTED
HAVING BEEN TRANSPORTED TO THE 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
BRITISH GYSPUM MANUFACTURING PLANTS Kirkby Thore Sherburn East Leake Barrow Robertsbridge
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 Thistle plaster range
THISTLE PLASTER Thistle plaster range
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 used regularly 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? RenovatingMasonry/blockwork - low/high suction Dri-CoatMasonry,DPC [replastering] X Raymasonry/Rib Laths, dense blocks,must have good key. Projection & UniveralFull 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-it A 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.
Why Thistle Plasters? Premixed - ready to use Suitable for a wide range of backgrounds Consistent setting time No Shrinkage Lightweight Choice of application methods
