• Check that the plinth PCC is in solid state.
• Check for leakage through the joints in rainwater/storm water/sanitary pipe. Rectify it, if found.
• Check wether the drainpipes are in condition. Rectify it, if found.
• Check the drainage chamber it should be free from solid particles.
• Check the flow of water through drain Hume pipes, it should be free flow.
• Check that there is no leakage through concealed pipes. If damaged rectify it.

Building maintenance internal: in in Preventive Maintenance of Building and Premises

• Check the flooring for antiskidness. Rectify, if required.
• Check whether all the passages are clear by permanent or temporary obstacles.
• Check passages turnings curved at all the change in direction.
• Check all the doors and windows glass. If found any damage rectify it or replace the same.
• Check the entire doors for proper closing. Rectify it, if required.

Painting of internal walls and production cubicles:

• Surface preparation:
  • Check the wall for wetness. If wet, allow it to dry.
  • In case of newly construction wall, apply lime mortar, after partial dryness achieved. The lime mortar application will help to absorb wetness in the wall and help reducing the drying period.
  • Remove the lime-cot, dust, dirt, stain, oil and grease by scrubbing the surface with wire brush.
  • Check for voids and cracks, if observed. These voids are to be filled up with cement grout in the proportion of 2:1 (cement : sand)
  • Level the surface with leveling compound i.e. putty/plaster of paris/terracotta/polyurethane as per the requirement.
  • Allow the surface to dry and harden. The drying period will depend on the prevailing climatic condition and temperature.
  • Scrub the surface to be coating with sandpaper to remove waviness and roughness, if any on the surface.
  • Apply leveling compound to remove waviness and roughness and allow the surface to dry and harden.

Coating of the prepared surface in Preventive Maintenance of Building and Premises

• The prepared hardened surface is to be checked for undulations and waviness.
• Apply one coat of primer of adequate thickness on the surface and allow it to dry.
• Once dry, scrub with sandpaper for final leveling.
• Apply first coat of adequate film thickness with required type of paint using brush/roller and allow it to dry.
• Apply final coat of paint and allow it to dry.

Protective Coating in Preventive Maintenance of Building and Premises

• Top protective coat is to be applied, for achieving required properties i.e. anti-fungal.

Painting of External Walls in Preventive Maintenance of Building and Premises

• Check the wall for wetness. If wet allow it to dry.
• Remove the lime-coat, dust, strain, dirt, oil and grease by scrubbing with wire brush.
• Check for voids and cracks. These voids are to be filled up with cement grout in the Proportion of 2:1(cement: sand).
• Flush the surface with water and allow the surface to dry.
  • Checking frequency half yearly.
