How to renovate old ceiling which is chipping off

  •  Chisel all loose concrete and plaster until you reach the solid concrete slab
  • Remove rust or corrosion from exposed steel reinforcement.
  • Clean surface with wire brush to remove dust and debris.
  • Apply bonding agent to prepared surface, 
  • Use PMM (Polymer Modified Mortar) for new layer of concrete. PMMs are stronger and durable than traditional concrete, they are less likely to crack.
  • Add steel fibre to new concrete, Steel fibre will help to strengthen concrete and reduce likelihood of cracking. 
  • Install carbon fiber reinforced polymer (CFRP) sheets on underside of ceiling. CFRP sheets are extremely strong and lightweight and they can used to significantly increase the load bearing capacity of ceiling.
