PAINTING OF PLASTERED WALLS WITH PLASTIC EMULSION PAINT
Painted
walls and concrete surfaces in high-rise buildings are usually painted with
emulsion paints. The term broth refers to the pigment and medium dissolved into
small globules in water. Many emulsions are available, such as oil, synthetic
resin and bitumen emulsions. Thus emulsions can be ordinary emulsions or
plastic emulsions. Plastic emulsion paints contain plastic and can give
different types of coatings such as flat eggshells.
The
most popular is acrylic plastic emulsion paints, luxury flat finish paint for the interior and exterior of painted walls. They can also be applied after applying
a suitable primer on fiberboard, asbestos, wood, metal, etc. It dries quickly
(touches and dries in an hour) and can be washed off with water after a month
of self-healing (when stains, grease marks and fingerprints appear). It also
has a low odour level).
Surface preparation. The surface for these paints must be prepared very
carefully. Old wall surfaces previously treated with paint or oil paint
distemper should be cleaned and rubbed down with sandpaper to ensure adhesion,
and this does not require the additional application of primer. Where limestone
has been used for washing and dry distemper, it is necessary to wash the
surface with water to remove traces of alkali and lose the distemper and to apply
an alkali-resistant cement primer. For new surfaces such as plaster, brick,
asbestos, fiberboard, acrylic paint can be applied as the first primer coat,
diluted with an equal amount of water. For new surfaces of wood, we need to use
a wood primer, and for new iron and steel, we use chromate primer.
Preparation of emulsion paints for
painting. Depending on the nature of the
surface and the number of coatings to be applied, the first coat (priming coat)
is diluted 100% with water and the subsequent coatings are diluted with 75 to
35% water. For best results we usually use the undercoat and finish coat,
allowing at least 2 to 4 hours between successive coatings. The paint comes in
more than 100 different shades, so the right choice of readymade composition is
possible.
What is the covering capacity of emulsion
paints?
Plastic
emulsion paints have a covering capacity of about 20m2/litre per
coat.
