The uploaded painting guide follows the practical sequence of protection, filling, smoothing, dust removal, degreasing, priming and successive coats. That sequence is retained here as an original technical workflow rather than copied wording or photography.

Painting & Decorative Coatings
A paint finish is only as durable as the substrate and preparation below it. Coating design therefore starts with substrate condition, moisture, contaminants, repair, primer compatibility, film build and curing environment before colour selection.

What this activity is
What this activity is
Painting systems protect and decorate gypsum, plaster, masonry, timber and metal. Performance depends on compatible layers, substrate moisture, surface preparation, film build and drying conditions.
What to expect
Expect most of the effort to happen before the final colour. Cracks, moisture, contamination, unevenness and previous coatings must be addressed; then primer and build coats are selected for the substrate. Final sheen should be reviewed under actual lighting.
01Protect adjacent work and establish safe access
02Repair cracks/voids and remove unsound material
03Sand, clean and de-dust/degrease as required
04Use the compatible primer for substrate and topcoat
05Apply build and finish coats within manufacturer recoat windows
06Inspect colour, sheen, coverage, defects and final protection under representative lighting
02 · ENGINEERING FUNDAMENTALS
Understand why the system behaves the way it does.
01
Ideal dry-film thickness DFT ≈ wet-film thickness WFT × volume-solids fraction
02
Theoretical spreading rate is governed by volume solids and target DFT; practical consumption increases with roughness, loss and application method
03
For condensation-sensitive coating, substrate temperature must remain safely above dew point according to the coating manufacturer
Primer is not a universal undercoat. Porous mineral surfaces, previously painted walls, timber and ferrous/non-ferrous metals can require different preparation and primer chemistry.
Uniform appearance depends on film continuity, wet-edge control, consistent roller/brush technique, lighting and batch/colour control. Touch-up can flash differently from the original coat if sheen, absorption or application method differs.
