M&L for guniting in ceilings for a high quality finished requires careful and skillful handling using skilled labours, good scaffolding stuff material mainly woodens or steel rakers, the surface should include thorough cleaning through air blasting or high pressure water jets. Additionally sandblasting with the gun, minus cement and at low velocity, effectively remove dust from reinforcement. if surface tends to absorb, it should be kept moist for six hours before guniting. Guniting requires wire netting 1.5mm thickness spread uniformly throughout the surface fixed with tinned tacks of wire stapples, a portland pozzolona cement, a guniting ratio of 1:3 is typically employed, water cement ratio for guniting is normally set at .3, maximum size of sand should not exceed 10mm and the distance between the nozzle and the backing surface should not exceed 1m. further nozzle velocity should not surpass 140m/s. in structure repair scenarios, the guniting thickness shall not be less than 30mm and rebound material is not advisable. Moreover rate of deposition of guniting is 15m3/hr. Thin polyethene or paper or cloth sheets should be used to cover the wall area so that cleaning is maintained and also measures should be taken so that tiles are protected from the falling materials. Demolition if any should be done prior to start of guniting and procedure should be properly followed at site and directions by engg in charge is specified.
