APPLICATION & CLEANING OF TOOLS Weathercoat GP can be applied by brush, broom or spray equipment. When applying by spray please consult with the local Terraco Technical Department. Apply onto the freshly prepared substrate in 2 - 3 coats, applying each coat at right angles to each other, to a total t hickness of 1. 5 - 2.0mm. Total consumption is 2.8 - 3.8 kg/m 2 (mixed Weathercoat). It is recommended that the total application thickness be 1.5 mm under tiles and 2.0mm for exposed areas. Clean tools and equipment with water immediately after use. CURING & DRYING Curing and drying times depend on ambient temperatures, atmospheric humidity and thickness of coating. Protect surfaces from wind and direct heat during application and curing. Do not apply in humid conditions > 80%. Weathercoat GP will be surface dry in less than 3 hours at 30°C. Allow first coat of Weathercoat GP to dry for a minimum of 6 hours before over - coating. Weathercoat GP should be left to cure for at least 7 days before water flood testing. For potable water tanks and fish ponds to prevent contamination of the water, after curing for 7 days, the surfaces of the Weathercoat GP must be thoroughly rinsed off with clean, cool water. Repeat the rinsing cycle until the required pH level has been r eached. Tiling work should be commence d after minimum 3 days of Weathercoat application. Protect surfaces from wind and sources of direct heat during application and curing. LIMITATIONS Do not apply during rising temperatures to avoid the risk of outgassing resulting in pin - holing. Do not apply on bituminous coatings. For exterior areas, do not apply if rain is likely over the next 24 hours. HEALTH & SAFETY Avoid prolonged contact with skin and eyes. For detailed information refer to the latest relevant Material Safety Data Sheet. PACKAGING & STORAGE & SHELF LIFE Weathercoat GP Resin is supplied in 5 kg jerricans .

1. WEATHERCOAT GP WATERPROOFING FOR WATER RETAINING STRUCTURES For further details visit: www.terraco.com V. 11 .201 8 - Issued by Terraco Technical Centre, Ireland for Terraco UAE Ltd. OVERVIEW PRODUCT GRADES/CODES Weathercoat GP is a high quality two - component, elastomeric, versatile and permanent waterproof coating suitable for use in areas with extreme climatic conditions. Weathercoat GP is specially formulate d for water retaining structures for e .g. s wimming pools & potable water tanks. White Grey 68533 68633 PROPERTIES Weathercoat GP is an elastomeric, polymer modified cementitious waterproof coating, supplied in two components, as a liquid resin and powder to be mixed on site before application. Weathercoat GP Resin Based on advanced acrylic resins , miscible with Portland cement and cement - based materials in various proportions, high resistant to alkalinity. Weathercoat GP resin is also suitable as an additive to mortars and screeds to increase their tensile, compressive and flexural strengths and r educes their water cement ratio. Weathercoat GP Powder Based on special hydraulic cements, precisely graded fillers, wetting agents and adhesion promoters. A dvantages:  Easy to mix and apply  Application by brush or spray  Pot life of more than 2 hour s at ambient temperature  Excellent adhesion to dimensionally stable concrete/render  Seamless permanent coating  Vapor permeability – allows substrate to breathe  High UV and weather resistance  Low temperature flexibility  Excellent water impermeable coating under tiles  Suitable for concrete potable water tanks  High flexibility  Non - toxic AREA OF USE Suitable for waterproofing of most building surfaces but especially where crack bridging and a high degree of waterproofing and pro tection is required such as for:  Potable water tanks , retaining concrete tanks , reservoirs  Swimming pools  Under - tile waterproofing  Fish ponds , decorative ponds  Planter boxes  Concrete roofs (exposed and under tile application) SURFACE PREPARATION Ensure substrates are clean and sound. Remove all existing coatings, cement laitance, unsound honeycombing and spalling concrete by suitable mechanical means. All dust, dirt and loose materials must be thoroughly removed by brush, broom or vacuum from the areas to be coated. Grind off all ridges and sharp projections. Scrape off all flaking material and remove oils, grease and other adhesion inhibiting substances. Mortar joints must be sound and finished flush with the blockwork. In sit uations requiring reinforc ement and at all wall and floor corner junctions, pipe entries and drains , it is recommended to apply the respective Terratape reinforcing membrane or Terraco Flexitape or Terraco Sealing tape , depending on area of application. Cracks and surface defects must be made good using suitable Terraco repair products. Create a fillet in the corners where required, prior to application of Weathercoat GP. Dry and porous substrates should be primed with Terrabond A (diluted 1:3 with clean water) or Terraco Waterpro ofing Primer (undiluted). Other surfaces should be saturated with water prior to application but no standing water should be present. MIXING It is recommended to mix full kits only. Place the resin in a clean mixing vessel then slowly add the powder while mixing for at least 3 minutes with a slow speed mixer (200 - 600 rpm) until the mix is completely homogeneous and lump free. Ensure the blade remains below the s urface of the mixture to minimis e the entrapment of air and that no powder remains unmixed on the sides and in the corners of the mixing vessel. Leave to stand for at least 5 minutes to release any entrapped air. Mix again for 30 seconds before application. During application , ensure occasional stirring to keep the aggregates in suspension. N ote : Do not add water to adjust or re - temper the mix. For bulk mixing, m ix only required kits of Weathercoat GP that can be used within its pot life.
