13	M&L forPrepare the surface thoroughly by cleaning, washing and removing dust, dirt, oil, grease, vegetation, plants and loose particles.In existing old terraces with brickbat coba or screeds, damaged or hollow portions, sharp edges, etc. must be cut and removed till the mother slab. The slab should be recoated with slurry of Dr. Fixit Pidicrete URP and cement in 1:1 proportion. After drying,the surface cracks must be filled with Dr. Fixit. Crack-X or polymer-modified mortar in case cracks are wider than 5 mm.Cracks less than 2 mm, should be cleaned free of dust with a vacuum cleaner. Apply Dr. Fixit Primeseal in the crack and let it dry. Then pour Dr. Fixit Newcoat into these cracks and waitfor it to dry.Bitumen based waterproofing treatments if existing, must be completely removed by mechanical scarification or by any other effective mechanical means.and Dilute 2 parts of Dr. Fixit Primeseal with 1 one part of water. This dilution will cover 7 to 8 sq.mt. Allow it to dry for6 to 8 hrs.Apply the first coat of Dr. Fixit Newcoat without any dilution at the rate of 2 m2 per litre and allow it to dry before taking up the second and third coats, the rate of application being the same. and open woven glass fibre mesh of 2.5 mm x 2.5 mm must be sandwiched between the first and second coat. While the 1st coat is still wet, place the fibre mesh on it. After the coat dries, start applying the 2nd coat of Dr. Fixit Newcoat. , to take care of al lmovements in cracks and cold joints in the substrate caused by variations of high and low temperatures. This reinforcement with fibre mesh shall be extended up to the drip mould over the angle fillets.The sequence of colours of Dr. Fixit Newcoat can be decided depending on the desired top coat colour. Drying time between coats will be 6 to 8 hrs.A llow the system to air cure for 7 days minimum. A total thickness of 1 to 1.2 mm must be achieved whenDr. Fixit Newcoat is dry. 7 days after application of Dr. Fixit Newcoat, it should be checked for its adhesion to the substrate. For this, mark a square of 5 cm x 5 cm, for every 200 sq. m of the area.Cut the square with a knife diagonally across the square. Rip the coating and check the coating’s thickness with vernier callipers, to see if the dry film has an average thickness of 1 mm. This should be done in every 200 m2.over the entire roof.
