3 Multi-Colour Stone Solution Product Introduction Micastone System is a water-based fluoropolymer resin-based clear paint, which is combined with special mica pigments. This coating can create various types of multi-colour stone finishing. Micastone System can be widely used from new buildings to repairing buildings by selecting undercoat materials matched best with the condition of substrates. Product Description Colour : Stand colour chart from Bonntile, tailor-made colour Package : Primer S (15 kg/ can) Micastone Intermediate coat (20 kg/ can) Micastone Topcoat (20 kg/ can) Application Efficiency: Roller, Brush % Aireless Spray 60-80% Other Spray Guns 50-70% Product Advantages Gorgeous Natural Stone-like Patterns - Giving an expression of beauty expanding with many colors even through liquid paintings. High Durability - Keeping long-term weatherability because of a fluoropolymer resin-based coating from an intermediate coat to topcoat. Low Pollution - With our distinctive Soil-release function, pollutants on the coating surface can be washed away by rain drops automatically. - Adding antiseptics and fungicides let dirty come off easily from the surface of films in comparison with regular stone finishing materials Stable Colour Tone - Colours, naturally given by powdery ceramics and marble chips, insure against discolouration and fading. Environmental Friendly - Water-based coatings from a primer coat to topcoat Water Drop Dirt Conventional Water Drop Dirt Soil Release 2

4 Recommended Usage Area of Use Recommended for application to exterior/ interior surface of the following locations: Walls and Columns Ceilings and Beams Fence Walls Roof Parapets Mouldings Bends, etc. Application Substrate Precast Concrete Poured in Place Concrete Plaster (Mortar) Stucco Existing Painting Film (undercoating on all kinds of old films like acrylic resin, polyurethane resin, epoxy resin, etc for renovations) Storage Requirement In order to ensure product integrity prior to the application, it is mandatory to comply with the following requirements of storage: Store materials away from open flames or excessive heat Do not expose materials to sunlight for a long period of time Keep all containers away from moisture Do not expose materials to freezing conditions Keep containers air-tightly sealed 3

This is because both compounds and calcium carbonate that are used in normal stone finishing materials: that improve colouring ability and intensity are not used which Micastone can express stone finishing designs by using special pigments that do not influence water resistance and weatherability. 4

7 Application Guideline Surface Preparation 1. New Surface 1.1 Curing time for the following substrates:- Plaster (mortar), stucco : 2 weeks Precast concrete : 1 week minimum (forced curing) Poured in place concrete : 3 weeks minimum Moisture content is less than 10% and alkaline ph content is less than Application surface must be smooth and free of voids or sharp projections. 1.3 Any application surface such as precast concrete, with excess pinholes, honeycomb, cracks, uneven or porous condition, should be filled up prior to the application. 1.4 Any application surface, with laitance, efflorescence, dust, rust, oil grease, curing agent etc. must be removed completely by brushing, sanding or other effective means. 1.5 Apply Tile Filler/Skim Coat onto sound, clean, dry and sufficiently smooth that accepted as an appropriate substrate for the application of Bonntile products. 1.6 Curing time for Tile Filler/Skim Coat : three days minimum Moisture content is less than 10% and alkaline ph content is less than Old Surface 2.1 All loose coating on the application surface should be removed by wire brushing, sanding or other effective means. 2.2 Any laitance, efflorescence, dust, rust or oil grease must be removed completely by brushing, sanding or other effective means. 2.3 All defective areas, hollow plasters and spoiling concrete must be hacked off. 2.4 Defective wall surfaces must be repaired by filling cracks or re-plastering of hacked off portions. 2.5 To paint areas must be cleansed by high pressure water jet at 1,500 psi and all surfaces should be of the sound, clean, dry and sufficiently smooth that accepted as an appropriate substrate for the application of Bonntile products. 6
