1. Walls and ceilings first, floors last. Move all fittings to the centre of rooms, freeing access to walls and ceilings as necessary.
2. Delint before scrubbing, scrub before wiping.
2.1. Vacuum off all loose fibres and cobwebs, THEN
2.2. scrub down surfaces with a firm brush, THEN
2.3. scrub/wipe off water-soluble stains with a rough towel, AND
2.4 use NaOh to remove grease and protein, or thinner and acetone to remove polymers, as necessary.
3. Uncovering plaster damage. This will involve
3.2. scraping off paint bubbles,
3.3. digging under cracked surfaces, and
3.3. deedging the plaster where it has expanded to protrude from the wall by as little as 50 to 200 micrometers ( 0.05 to 0.2 mm ).
[ Identification and replacement of faulty pipes and wires would be around here. Future note. ]
4. Leveling plaster.
4.1. Any cavity deeper than 3 mm may be considered for a base-level of cement, perhaps made with latex plasticiser instead of water.
4.2. White plaster can be coarsely applied as a base for paint - this may take a few iterations of
4.2.1. laying with a scraper / trowel / screed / level of apprpriate width,
4.2.2. drying,
4.2.3. post-dry levelling, and
4.2.4. pre-painting with sealer / primer.
5. Painting.
5.1. If by mistake a paint of the wrong tone or sheen is obtained, supplies can be used on the undercoats.
5.2. Whichever layer of paint is final, should be examined from a slanting angle against bright light to check for the matching of sheen.

Operational Timings
A few hours of drying and setting time are required between certain steps. So work on a site may need to be spaced out in gaps of four to hours, for a tropical climate. This provides up to three work sessions per day.
