15. SAFETY. The chemical in raw state must be treated with the same respect as any other toxic liquid. The basic rules will apply and include the following: Wash hands thoroughly after use. Do not dispose of into sewers. Store in a cool dry place. Do not store in direct sunlight. Replace cap after use. Avoid inhalation. Do not drink or swallow. Keep out of reach of children Avoid spillages. Do not damage or puncture containers. Wear surgical gloves during mixing and dispensing. Apply a barrier cream to hands prior to dispensing. Wear protective glasses during mixing and dispensing. Use a 30% household vinegar solution to neutralize if necessary. In case of a vehicle accident, advise the authorities that the chemical is extremely slippery.

16. TANK FILLING PROCEDURE. HOLDING TANK. The dispensing tank is of “flowbin” type. Reconditioned tanks sell for approximately R1000 The aluminium support frame allows for ease of installation and may be safely placed on a wood pallet or brick support to the required height. After filling, the cap is replaced and dispensing may commence if and when required. MIXING. The raw concentrate has been stabilized and is ready for use. The mixing ratio is as follows: 50 Liters concentrate to 950 liters water = 1000 Liters PCT 56. 25 Liters concentrate to 475 liters water = 500 Liters PCT 56. Add the concentrate to the holding or dispensing tank. Avoid spillages. Add water to the holding tank by means of domestic hose pipe and ensure that the pipe protrudes to the bottom and extends +/-300 mm at right angles. This will create a natural vortex to enhance dispersion of the concentrate and also reduce foaming.

17. DISPENSING PROCEDURE. Two types of containers are approved and the choice of container is dependant on availability and price as per relevant geographical areas. The “Dairypack” transparent “PET” container has excellent aesthetic appeal and enhances the colour and label. This container is however prone to mechanical damage due to poor flexibility. The standard “HDPE” container has rigorous design and is less prone to mechanical damage. Both containers are approved for transport of chemicals of low and high PH values. The chronologigal dispensing procedure is as follows: 1.Identify the batch number at the bottom of the container with a permanent marker or label printer. (refer to batch identification) 2.Attach the plastic handle to the container (5 liter “Dairypack “PET” containers only). 3.Apply front and rear labels. 4.Fill the container at high volume progressively decreasing volume to reduce foaming. A flexible transparent pipe extension to the dispensing tap may be usefull. 5.Seal container with relevant cap. 6.Remove spillages immediately with a wet cloth to avoid white spotting on containers. 7.If containers are reused during dispensing, flush immediately to avoid crystalization. 8.After dispensing, replace the cap on the flowbin to avoid gas contamination.

18. QUALITY ASSURANCE. THE QUALITY MANAGEMENT OF THE ENTIRE MANUFACTURE AND DISPENSING PROCEDURE IS OF UTMOST IMPORTANCE AND MAY NEVER BE PROSTITUTED. “PCT WATER REPELLENT TECHNOLOGY” HAS GAINED EXCELLENT BRAND AWARENESS AND ADDED VALUE. ONE SINGLE BAD BATCH MAY DESTROY ALL OF THIS TO THE DETRIMENT OF THE MANUFACTURER AND OTHER LICENSEES. The following testing procedure must be conducted and recorded as per the relevant batch certificate after production of every batch. Certificates must be kept on file for 3 (three) years. Claims for failures will only be investigated and honored if relevant batch information and samples are available. 1.Insert a litmus strip for 30 seconds to confirm correct PH. Remove from chemical and leave for 5 minutes to react. The color on the strip will change to a dark purple. (See lithmus reaction) 2.Draw a liquid sample with a syringe and spray out on a cement surface. After 2 hours apply water to confirm repellent properties. 3.Draw another sample and dispense into a container ( 50ml tablet container). Confirm the color standard and store in a cool dry place. Sample to be retained for 3 years. 4.Record on batch certificate and staple litmus strip for reference.

21. BATCH CODING. It is important to maintain quality consistency in accordance with the quality management system and it is therefore necessary, in particular when several dispensing centers or areas are applicable, to maintain a formal batch coding format to ensure that quality aspects are maintained. The following procedure must be applied: 1. All batch numbers to be recorded at the bottom of the container (permanent “koki” pen or small label) 2. First digit identifies the area ( “W” will be Witbank) 3. Second digit identifies the year (9 will be 2009) 4. Third digit will identify the month ( 8 will be August) 5. Fourth digit will identify the batch number for the month. Example: W 9 8 5

29. “ LIKE WATER OFF A DUCK`S BACK ” Frequently asked questions !

30. WHY IS IT NOT POSSIBLE TO APPLY PLASTER TO A SURFACE PREVIOUSLY TREATED WITH “PCT 56” HOW DOES CEMENT CURE. A Portland cement plaster mix gains strength by means of chemical and physical interaction with water, aggregate and the substrate or surface that it is applied to. The most important requirement in curing of cement plaster is the presence of sufficient water in the mortar or mix to hydrate the cement paste. Water acts as a catalyst for curing. A chemical reaction commences when water and Portland cement are brought into contact with each other during initial stages of mixing either by mechanical mixer or manual mixing. A series of new chemical reactions follow when compounds form which bind together the grains of sand or mortar within the mixture and the substrate or surface simultaneously. Water is the critical factor in this reaction as it actually combines with the cement and the substrate. This reaction is designated “hydration”. If hydration is unable to take place, failure of the plaster mix will be evident. In the event that a surface is treated with “PCT 56” prior to applying plaster, “hydration” can not take place due to the water repellent properties of “PCT 56”. Therefore, and under no circumstances, can “PCT 56” be applied to a surface or substrate as an intermediate treatment between two plaster surfaces or underlying brick substrate,

31. WHY IS IT NOT POSSIBLE TO APPLY “RHINOLITE” TO A SURFACE PREVIOUSLY TREATED WITH “PCT 56 WATER REPELLENT TECHNOLOGY”? “ Rhinollite” has over many years become a generic name. It is a lightweight retarded hemihydrite substance where 2 molecules of compound will mix with 1 molecule water. The product is composed of hydrous Calsium S ulfide, lime, natural filters, specialized chemicals and minute mica particles and available to the trade as a white/grey powder. All the ingredients are catalyzed when water is added to achieve a homogenous paste. Application of the product is specialized and some “know how” required to create a successful finish. The paste is applied to the cement plaster surface, left for approximately 30 minutes and “milked” with a wooden trowel to achieve a thin film which hardens to a speckled skin. The water content also acts as a conveyance to ensure that penetration into the cement substrate takes place. (to convey the product into the cement surface) If the cement substrate has been treated with PCT 56 prior to application, the water conveyance will be unable to penetrate into the surface resulting In adhesion failure and delamination of the “Rhinolite”. However, a surface treated with “Rhinolite” may be sucessfully treated with “PCT 56 WATER REPELLENT TECHNOLOGY”

32. HOW LONG WILL TREATMENT LAST? Due to the inorganic nature and under normal conditions it will last forever. MAY THE SURFACE BE OVERCOATED WITH PAINT AFTER TREATMENT? All leading paint brands where tested. In all instances the life expectancy of the paint was extended dramatically. No paint failures where rcorded. WILL I USE LESS PAINT? During treatment with PCT 56 the chemical enters the microscopic capillaries within the surface to form a solid bond. When paint is applied, it is unable to enter these microscopic capillaries. Less paint is therefore required. The surface profile of the surface is however not disturbed. MAY WATER FEATURES BE TREATED WITH PCT 56? PCT 56 will also perform in submerged conditions. Due to the high alkalinity growth of algae or aquatic bacteria is prevented. MAY A “KOY” DAM BE TREATED? Maintenance of a “Koy” dam includes stability of water content and PH as well as addition of oxygen enhancers. This entire process requires some effort and is expensive. If maintenance is not conducted in accordance with recommendations, PCT will reduce the oxygen content which will be fatal to the fish. Recent failures occurred when it was found that no maintenance was conducted. IN VIEW OF THE RISK “PCT 56” MAY NOT BE SPECIFIED FOR “KOY” DAMS OR ANY WATER FEATURE CONTAING FISH SPECIES.

33. WHAT ABOUT DOMESTIC SHOWER CUBICLES? The perfect shower has yet to be built!!!! Penetrating damp on tile areas are the main cause of paint failures on adjacent walls. Water or moisture penetrates the tile grout and the bottom corners at right angles to the floor. Imprtant: All areas to be treated must be dry and free from any moisture or body fats!. Leave for as long as it takes to dry. Spray the entire tile area liberally with PCT 56. Leave for 1 hour and remove excess chemical with a damp cloth. This will prevent white spotting on the surface. On adjacent walls, remove all loose and flaking paint and fill imperfections with a suitable filler. Apply PCT 56 to the contaminated area, leave to cure and commence with painting. WHAT ABOUT KITCHEN CEILINGS? Heat, moisture and food fats create the ideal atmosphere for incubation of bacteria and algae. Paint failures are evident!. Gypsom Rhinoboard or asbestos ceilings may be treated with PCT 56 to prevent paint failures. WHAT ABOUT MILDEW? Mildew requires a lot of moisture, ideal temperatures and organic fat to grow. However, extensive growth is achieved only when it has a surface to “hold on to”. A surface treated with PCT 56 has the ability to restrict mildew growth by depriving a “hold on to” surface

34. WHAT ABOUT CEMENT PAVING BRICKS? Due to their composition paving bricks are extremely absorbent and act like a sponge when wetted. Internal capillaries are large and any oil and wastage or spillages are absorbed. Removal is impossible. Treatment with copious amounts of PCT 56 will deprive the bricks of any absorbing properties. Any oil spillage will lie on the surface and may be washed off with a domestic detergent. WHAT ABOUT PREFABRICATED WALLS? No formal specification exist for manufacturing or quality procedures for prefabricated walls. Municipal by-laws clearly express that prefabricated walls are approved for identifying surrounding borders only and no differentiation are made with steel wire fencing. Slabs are reinforced with steel and mechanical breakdown occurs when water is absorbed and the steel becomes affected with rust or corrosion. In certain conditions entire slabs are destroyed. This entire process is aggravated by underlying damp coarse membrane. Prefabricated walls are often painted to add aesthetic value to property. Case histories have revealed that the life expectancy of prefabricated wall sections previously treated with PCT 56 and painted with a high quality paint increased 5 x.

35. WHAT ABOUT CEMENT ROOF TILES? Being of cementitious nature and continually subjected to severe atmospheric conditions such as rain, hail and temperature variations the life expectancy of cement roof tiles are limited. Mechanical properties progressively reduce with ageing when water leach the lime from the cement and over prolonged periods the tiles become brittle when all mechanical properties are destroyed. Costly replacement becomes necessary. This occurs between 6 – 8 years. In January 2004 two tiles where submitted for accelerated “Weatherometer” tests by a leading laboratory who specialize in this field. One tile was treated with PCT 56. After 4 months, basically representative of 14 years actual practical exposure in accordance with SABS requirements, the tiles where removed. On removal from the test equipment the untreated tile shattered while the treated tile showed no signs of any mechanical failure other than a colour change from red oxide to light brown due to oxidation of inherent oxides. The life expectancy of cement roof tiles will improve dramatically when treated with “PCT”

36. CAN I SUBSTITUTE WATER WITH PCT 56 WHEN MIXING CRACKFILLER OR TILE GROUT? When domestic crackfillers and grouts are mixed with PCT 56 to achieve a paste they will obtain water repellent properties when curing has occurred. However, in some instances the viscosity of the paste increases dramatically and when water is added the viscosity is reduced to normal. Tests conducted with leading brand names indicated that the curing period is reduced and mechanical properties improved considerably. SANDSTONE. Sandstone, in various precut forms, has been used extensively in the building industry for many years and has tremendous added value. Our country can boast some of the most excellent preserved historical sandstone buildings. However, in the natural state sandstone draws water like a sponge. Although this feature is not detrimental to the quality or life expectancy, sandstone buildings are always cold due to evaporation when the water molecules chill the air. Treatment with PCT 56 restricts absorption thus reducing the chilling effect.

37. ASBESTOS SHEETING. SUBSTRATE COMPOSITION. Asbestos sheeting and corrugated sections are composed of Portland cement, fine aggregate and asbestos fiber to improve mechanical properties and durability. During ageing and prolonged atmospheric exposure (wind, hail and rain) the lime is leached from the cement by water and moisture. The mechanical properties are reduced and the asbestos fiber exposed. Release of the asbestos dust fiber into the atmosphere is a severe health hazard when inhalation of the dust can lead to “asbestosis” in humans. “Asbestosis” is a chronic disease and is characterized pathologically by interstitial fibrosis and asbestos bodies. Recent laws restrict manufacture of asbestos products, however, many older buildings remain sheeted with asbestos sheeting. TREATMENT. Treatment with PCT 56 will prevent water or moisture penetration, prevent the leaching of the lime and reduce exposure of the asbestos fiber. Painting of the surface with a durable paint will extend the life of the sheets by additional 20 – 25 years.

38. PAINT BOOSTER AND THE SCIENCE OF PAINT COLOR. The color of paint is divided in four categories as illustrated in the following schematics: DRAMATIC REDUCTION IN VOLUME DRAMATIC REDUCTION OF TITANIUM DIOXIDE, CARBONATES, OXIDES TO ALLOW FOR ADDITION OF TONERS. WHITE & PASTEL MEDIUM DEEP ULTRA DEEP SATURATE UNSATURATE WATER TITANIUM DIOXIDE, CARBONATES, OXIDES RESIN REDUCED VOLUME REDUCED TITANIUM DIOXIDE, CARBONATES, OXIDES TO ALLOW FOR ADDITION OF TONERS GREATLY REDUCED VOLUME GREATLY REDUCED TITANIUM DIOXIDE,CARBONATES, OXIDES TO ALLOW FOR ADDITION OF TONERS

39. DAY 2 2 DAY 4 DAY 6 PAINT BOOSTER AND CURING OF PAINT. CROSS SECTION OF A PAINT FILM... WATER AND “PAINT BOOSTER” RESIN MOLECULES AND COLORANT FAR APART, NO COHESION. WATER AND “PAINT BOOSTER” RESIN MOLECULES AND COLORANT MOVING CLOSER, LIMITED COHESION. PAINT BOOSTER COMMENSING CURING STATE “PAINT BOOSTER” IN CURED STATE RESIN AND COLORANT IN COHESIVE STATE

40. THE UPCOMING MARKET REQUIRE AN INFERIOR QUALITY PAINT THAT IS INEXPENSIVE WHEN QUALITY IS NOT A PREREQUISITE. THESE COMPOSITES CONTAIN VERY LITTLE ACRYLIC RESINS (INFERIOR QUALITY POLIVYNAL ACETATE) AND EXTENDED WITH COPIOUS AMOUNTS OF CALSIUM CARBONATES. MECHANICAL PROPERTIES ARE EXTREMELY POOR AND LIFE EXPECTANCY NOT MORE THAN 1 SEASON. WHEN PAINT BOOSTER IS ADDED, IMMEDIATE GELLING SYMPTOMS OCCUR DUE TO THE HYGROSCOPIC PROPERTIES OF THE CALCIUM CARBONATE WHEN THE PAINT BOOSTER COMPETE FOR WATER. AFTER THOROUGH MIXING OR AGITATING THE VISCOSITY RETURNS TO NORMAL. THESE PRODUCTS ARE NOT PRODUCED IN CONTROLLED TINT BASIS AND FOR REASONS OF ECONOMY MERCHANTS WILL OFTEN IGNORE RECOMMENDED PRACTICE AND TINT TO A COLOR BY FAR EXCEEDING THE SATURATION POINT OF THE PAINT. THE SYMPTOM OF OVER SATURATION IS “FLOTATION” OF PIGMENTS ON THE SURFACE OF THE PAINT. AFTER APPLICATION TO A SURFACE OR SUBSTRATE COHESION OF THE BINDER MOLECULES WILL NOT TAKE PLACE AND THE PAINT WILL FAIL WITHIN DAYS. GUESS WHAT???? PAINT BOOSTER WILL BE BLAMED. PAINT BOOSTER AND INFERIOR PAINT,

41. WHAT ARE THE IMPLICATIONS IF “PCT 56” IS APPLIED TOO THIN OR IF THE SPREADING RATE IS INCREASED DRAMATICALLY. If “PCT 56” is applied too thin, or by means of a mist spray, penetration into the surface or substrate will not take place and the chemical will crystalize on the surface. This will defy the object of the characteristics and performance of the product. It is therefore important to apply “PCT 56” in accordance with the porosity of the surface to ensure that penetration into the surface takes place without the occurrence of damming.
