Application
Fillers:
Damaged surfaces may require filling and sanding to provide a
smooth, even surface.
Sanding:
The most common abrasive papers are:-
Glass paper - ideal for roughening smooth surfaces to achieve a
key.
Aluminum oxide paper - long lasting but more expensive.
Silicon carbide (wet and dry) paper - used with water or
turpentine. Best for dulling glossy surfaces where a smooth finish
is required.
Stirring:
Adequate stirring prior to use is essential for correct colour
consistency. Stir with alternating circular and lifting motions,
using a flat paddle until the contents are uniform. Continue
stirring at regular intervals during application. Where you have
more than one can of the same colour for a job, mix the contents of
the can together to ensure colour consistency.
Personal Protection:
Ensure the area is well ventilated. Wear old clothes, a painters
hat, gloves where necessary and a mask or respirator when sanding
or spray painting. A respirator is also recommended when applying
oil based coatings in confined spaces or if ventilation is
poor.
Sequence of Painting:
Painting should usually occur from the top down.
For interior surfaces
- Ceiling 1st coat.
- Walls 1st coat
- Ceiling 2nd coat
- Woodwork undercoat.
- Walls 2nd coat
- Woodwork finish coat.
For exterior surfaces
Roof, eaves and verandahs, walls, gutters and downpipes, windows
and doors.
Climate:
Warm, dry days with little dew or frost are the best conditions
for painting. Painting should never be carried out under damp
conditions. Inside heating and good ventilation assist the drying
of internal paintwork during cold weather or high humidity. Avoid
painting when temperature is below 10ºC or above 35ºC.
Moisture should not be present on the surface being painted unless
manufacturers printed instructions say otherwise.
Painting large areas:
Use a roller on a pole or extension handle to cover the full
height of the wall in a single stroke. Spread paint evenly until
the roller is almost dry. Go back over the area and roll lightly
down the surface to give a smooth even finish. Reload the roller
and paint the adjoining areas in the same way. Make sure when
joining the sections to roll from the dry area back into the wet to
avoid lap marks.
