MASTER ROOF A two layers ultimate solution for waterproofing and roof coatings Master Roof is a white hybrid polymeric waterproofing and coating material resistant to extreme temperatures and extreme environmental conditions. Master Roof features excellent solar re flectivity and emissivity properties. The material is applied as a thick paste fo rming a seamless, decorative and flexible membrane that prevents water penetration and extends the life of the roof. Product Uses: ƒ Waterproofing new roofs that have va rious penetrating devices or complex geometrical shapes. ƒ Waterproofing complex areas, where Bituminous Membranes can not be used. ƒ Waterproofing existing roofs that are in n eed of renovation and are covered with old bitumen or old bitu minous membranes. Benefits & Advantages Resists to Extreme Temperatures | High productivity | High strength and elasticity | Two colors application to guarantee an absolute coverage | Saves the need of an additional white coat | environmentally friendly | Easy application | High UV Resistance | High Solar Reflectance and Infrared Emittance | Instructions for use Surface preparation ƒ All surfaces to which Master Roof is to be applied must be sound, stable with an even finish and free from dirt, dust , loose debris, grease etc. All wires and pipes should be elevated. ƒ Make sure that the slopes are such th at they prevent water from ponding. ƒ Before applying Master Roof, apply a primer layer as follows: ƒ For different surfaces with a good preparation, sloop etc' such as concrete, Bituminous membrane, Aluminum, Galvanized steel, asbestos, etc' apply a first layer of diluted white Master Roof with water in a ratio of 1:1 at a quantity of 250/m2 ((0.44 gal/100 sq.ft). ƒ For bitumen surface apply Master Prime at a quantity of 250g/m2 (0.6 gal/100 sq.ft). For better bonding and reducing the risk of blistering ƒ Above Bituminous membranes, co ncrete, SPF and wood surface: Apply Epoxy Primer XL-100 at quantity of: 100-300 gr/m2. ƒ Above PVC, Aluminum, Galvaniz ed steel, asbestos surface: Apply Super Primer at quantity of: 100-300 gr/m2.    Application Master Roof is applied by two layers. Each layer has a different color in order to ensure that complete layers have been applied: First layer – Peach Second layer – White ƒ Apply with a brush / squeegee / airless spray a first layer (Peach) at a quantity of 1.5 kg/m 2 (2.6 gal/100 sq.ft). ƒ Let dry for 4-6 hours. ƒ Apply with a brush / airless sp ray a second layer (White) at a quantity of 1.5 – 2 kg / m 2 (2.6 – 3.5 gal/100 sq.ft). ƒ Let dry for 4-6 hours. ƒ Enable a complete dry of 14 days before footsteps. Remark: it is recommended that for each new project the soundness of surface, the adhesion on site be tested ahead of time. It is advised to take in consideration the local weather condition such as ambient temperature and air humidity during the application of the material, and after the application until the material is dry to it's full depth. Avoid freezing temperatures, or excessive moisture on the material before it is dry to it's full thickness.    Equipment care Clean tools with water, preferable while the material is still soft.
