concrete, block paving and indoor surfaces as well as all other surfaces outdoors Available in a wide range of colours and easily made up for special colours Most can be applied by brush, roller or powered equipment Sub-types are a Chlorinated rubber − Solvent base paint applied in one or two coats by airless spray equipment or by roller/brush Becoming unacceptable on environmental grounds because of high VOC content Cheap and cheerful but gradually being replaced by water based or MMA equivalents Likely to be banned by EU legislation in the near future b Epoxy paint − Solvent base paint either one or two pack types and applied in one or two coats Lower VOC’S than chlorinated rubber but still includes organic solvents Applied by airless or air assisted equipment and by roller/brush c Water-base Acrylic Paint − No organic solvents, slower drying Ideal for environmentally sensitive areas Applied in single or double coats by suitable equipment or by roller/brush Note: Water-base paints require suitably modified equipment containing stainless steel connections and fittings throughout More expensive than chlorinated rubber Slow drying in high humidity regions/conditions will limit suitability d Methylemethacrylate Paint (MMA) − Available in thin or high build versions and suitable for all surfaces Applied by specialist equipment Usually very hard wearing but also much more expensive than other paints or thermoplastic Strong smell of ammonia when being used may affect users and other persons nearby Special high performance variant used for wet night marking Ideal for high stress locations where Main Contract Builder Work Q2 THAO DIEN Mixed Development A8-20: BASEMENETS SPECIFICTION other materials wear quickly i.e warehouses and depots with forklift and/or HGV movements This product is growing rapidly in the UK for locations where Thermoplastic is unsuitable Some surfaces will require a tack-coat Seek advice from specialist contractor offering this product range 4.2.2 Hot Applied Thermoplastic Used for more than 95% of public road markings in the UK since the 1950’s Extensive use around the world Principal colours are white and yellow but others such as blue, red and green are available White material usually includes glass beads in the mixture to give night time reflectivity and additional glass bead application to the surface can be specified Adheres to bitumen surface by heat transfer bonding a) Application Methods: Screed, Spray or Extrusion equipment by specialist contractors only b) Suitable for: Outdoor use only on bitumen based surfaces such as asphalt, surface dressing, slurry, tarmac etc c) Can be used on concrete and block paving with care but more likely to fail A tack coat should be used first to improve adhesion d) Not suitable for: Indoor surfaces, factory floors, underground car parks, multistorey car parks (except top deck) Thermoplastic requires the action of weather (rain especially) to maintain good appearance and if used indoors or under cover is likely to discolour badly e) Poor adhesion properties to paint or other materials unless they are well worn and expose bitumen surface beneath f) Special variants made for Raised Rib and Wet Night Marking Other advantages: New Thermoplastic markings will normally adhere well to existing thermoplastic lines so it is often used to renew old worn markings Can be applied up to 4mm thick and therefore will give good wear characteristics in most circumstances 4.2.3 Pre-formed Thermoplastic Comes to user in ready-made form Precut logos and designs are factory made Use and wear characteristics are as per Hot applied Thermoplastic above Ideal for prestige locations, complex logo designs and multi-colour usage Expensive by comparison with Hot applied Thermoplastic Applied by hand and gas torch A thermoplastic is a polymer that turns to a liquid when heated and hardens to a very glassy state when cooled sufficiently Thermoplastics can go through melting/freezing cycles repeatedly and the fact that they can be reshaped upon reheating gives them their name Therefore Thermoplastics are ideal for road marking 4.2.4 Tape Available in rolls Many colours are available Easy to apply but often easy to remove by vandals Different types give different wear characteristics i.e foil type is very thin and wears faster than thicker multi-layer tapes Expensive but easy to use May require additional adhesives i Suitable for smooth surfaces indoors or outdoors ii Not suitable for open textured surfaces such as porous asphalt, SMA etc 4.2.5 Temporary Materials Tape and paints are available for temporary situations and are easily removed when no longer required Used for sporting events i.e marathons and TV/Film sets or advertising Do not apply thickness higher than recommended on bituminous or asphalt/tarmac surfaces as “bleed-through” may occur Main Contract Builder Work Q2 THAO DIEN Mixed Development 4.3 A8-20:
