The quality lity of of the coating is is dependent on on the substrate and material tem temperature. All All materials whether loose or on pallets have to be stored in a covered area and protected fro from UV and sunlight. Deteriora eterioration tion of of the product product may be caused dueto improper storag storage and at high temperatures. App Application of coating should be avoided in case of extreme weather conditions like sand storm or rain. The ambient tem temperature during application application should be between 5°C and 45°C.
The fol follo lowing wing Equipments Equipments are required during application: Protective Protective clothing clothing:: Gloves, loves, face facemask, overa overalls, lls, and safety goggles App Application equipments: Slow low speed drill drill machine with less less than 500 rpm with ith a suitable spiral spiral mixer Wooden Wooden press & lap rollers rollers Brush / roller Steel scrapper Cotton Cotton waste Solvent olvent clea cleaner Measuring suring tape Cutting knif knife, e, scissors
SECTION ECTION II: APPLICATION APPLICATION INS INSTRU TRUCTIONS CTIONS
Surface rface Preparation: tion: The surface should should be free of any cement laitance laitance, oil, oil, grease, curing compound and any other other deleterious leterious materials. Lig Light mechanical grinding grinding / grit blasting blasting / high pressure water jet may be used to clea clean the surfac rface to be coated, based on the the degree of contamination. contamination. Nail heads and other protrusions protrusions that that are likely likely to damage the coating must be removed oved or ground. Structurally unsound unsound and friable friable concrete must be removed and repaired. Honey Honey combed or spalled spalled concrete, surfac surface irregularities, ularities, blow blow holes holes to be repaired with ith a suitable suitable POLYCRETE concrete repair mortar. Priming: It is is highly highly recommended to apply a priming coat coat prior prior to the the applica pplication tion of POLYCOAT RBE. The priming coat is made made by diluting diluting POLYCOAT RBE with with 20% clean water. App Application: Stir tir the contents of the drum thoroughly befo before re application pplication to remove remove all sediments. sediments. POLYCOAT RBE may be applied applied by brush, roll roller er or squeegee. It It may be applied pplied on on damp surface surface but ensure that there is no water logg logging. The The coating ting is normally lly applied in two two coats. Aft After the application of the fir first coat, apply the second coat at right angles to the fir first coat and only afte fter the fir first coat has dried completely. On On vertical vertical areas, apply the coati coating ng in multip ltiple le layers to avoid avoid sagging. If cement ent sand render or plas plaster ter will ill be applied on top top of of the coatin coating, g, then in order a better key for for bonding bonding it is is recommended to broadcast the coating with clea clean dry sand whilst hilst the coating coating is still still wet. Clean all too tools ls imm immediately with with water after use. Hardened materials can be removed oved mechanically only. only. It is recommended to protect protect the applied applied coating from from getting tting damaged during backfil backfilliling ng. Such protectio protection n can be provided provided by suitable suitable protective protective materials like like cement sand screed or an asphaltic ltic protecti protection on board board (BITUBOARD) or or any other other material as specified pecified in the the project specif specificatio ication. n.
