Work Method Statement for Plastering and Pointing on the Masonry

Work Method Statement for Plastering and Pointing on the Masonry

SCOPE/PURPOSE
This procedure covers the methodology to be followed for carrying out plastering and pointing work over the masonry in line with the approved technical specifications.

CODES / SPECIFICATION
IS 1661

RESPONSIBILITY
Responsibilities of all concerned is clearly mentioned with respect to overall administration and implementation in the approved Organogram.

MATERIALS TO BE USED
Cement, Sand, Water, Chicken mesh, Waterproofing compound.

SAFETY REQUIREMENT Safety in Plastering and pointing:
  • Use double scaffolding always and ensure the scaffolding is adequately braced with the permanent structure, for working in heights.
  • Ensure the workers use safety appliances like safety belts in height, helmets, safety goggles while carrying out chipping etc while carrying out plastering and pointing in heights.
  • Ensure the working area is kept clean for easy access and protect edges of opening by barricading etc while working.
  • Ensure the area of working is well lighted (provided with lights) so that work area is easily accessed and moved around safely by workers.
  • Inspect the scaffolding before starting work.
  • Access platform/working platform double hand railing to be provided.
  • Proper illumination to be provided during the work, if required.
  • Educate the workmen through pep-talk meeting.
DEPLOYMENT OF EQUIPMENT
As per the requirement and the direction of Project Manager.

DEPLOYMENT OF LABOUR
As per the requirement and the direction of Project Manager.

IMPLEMENTATION
Preparatory Works (Before Taking up Plastering): Work Preparation.

Complete all internal / external works like
  1. Filler walls in structural frame work
  2. Fixing frames of doors, windows and ventilators
  3. RCC pre-cast jali works,
  4. Fixing and concealing all kinds of pipes (getting concealed in the walls)
  5. Complete all pipelines works to their final positions and levels for Water supply lines, Sewer pipelines, Telephone conduits, Electrical conduits, TV Antenna lines & piping work for other services if any coming on wall surfaces to be completed with their hood covers fixed and finished to the final surface level of the walls / ceilings.
  6. All lightning protection like earthing to be completed.
Surface Preparation:
Do prepare the surface to be plastered by
  • Clearing all dirt and loose matter
  • Chipping and clearing of mortar dropping.
  • Chipping and clearing of unevenness in the masonry, concrete works in ceiling and walls of rooms.
  • Chipping and clearing the debris in areas of skirting and dado after marking the cutoff levels clearly.
  • Raking out joints if necessary for proper keying

Can i get the tolerance limit for plastering surface undulation..

There is as such no limits on undulations on surface which you want to plaster.
If you want to make plaster in straight line without undulation.

You first need to make the surface on which plaster to be applied plain by applying backing coat.
the thickness of any plaster coat should not exceed more than 25mm.
if its more than 25 mm, you need to do 2 back coats/ chat coat before proceeding to plastering to avoid shrinkage / cracks, due to settlement by own weight of coat.

what is the maximum number of coats to be made

It depends on the

surface on which plaster is to be applied.
Cost incurred due to plastering.

Normally plaster done in 2 coats. back coat and finish coat.

Thickness of plaster should bot exceed more than 25mm during plastering.

We can have plaster of 75mm too, but its not a good idea to have such thickness as it will incur the cost of extra system and materials, which no one will pay so the thickness depends on the purpose for it is done.

Sir, What is the methodology to perform 50mm thickness Plaster?

do alternate to avoid 50mm plastering by chipping or something based on site condition, what it will be a good ,because more thickness of plastering will lead to crack in future and the workmanship should not be 100%.

Sir, What is the methodology to perform 50mm thickness Plaster?
if u need methodology refer IS 1661 (1972),ITS CLEARLY MENTIONED (QA AND QC )
rendering coat 10 -15mm u can do and its cured atleast 2 days ,maximum 7 days
then other each coat 3 mm to 8mm u can do then its cured atleast 2 days
follow the same 50mm thick plaster makes 5 coat.
So do alternate .


if u follow this same it will be big process and it will affect the progress ,it will be more expensive .

Sir, you can do fix granite skirting on stone surface directly by using C2 class tile adhesive.

Do remove the pointing mortar from skirting area and make surface dressing (removal of paint from stone) by hand grinder.

Good Evening Sir
Thanks for your replies.
I ve taken dubbing coat with chicken wire mesh for undulation and also as not to distrub existing pointing.After that chemical screed bed above plaster..
Is this will be better.

Regards.
