Acrylic paint is an instant drying paint that is made by appending colours in polymer emulsion, metal soaps, silicon oils, stabilizers, and plasticizers. The important characteristic of the acrylic paint is that it is water-soluble but after application, it becomes water-resistant. It is a water-based paint that means it needs to be dissolved in water for its use, but once it is applied to the surface it becomes water-resistant. The first acrylic paint was manufactured by a German chemical company in 1934. The acrylic resin was invented by Otto which was altered into acrylic paint in a short time. This paint is used for both household painting and also art paintings. The acrylic paints are available in different varieties and grades.
Apart from providing texture to the building and protecting it from the environment, these paints are designed to withstand hardcore challenges and provide protection. The qualities that are required in acrylic paint are thermal insulation and anti-condensation. Acrylic paint can be used on any surface except metal, ceramics, and wood. These are water-based, fast-drying paints which on drying give a strong paint layer. These are used in decorative painting to decorate a different object with various colours. The anti-condensation and thermal insulation properties of the paint make it invincible and the first choice by a lot of users. These properties are induced in the paint synthetically to achieve long-lasting paint. Condensation is one of the common problems in houses, the condensed water damps the surface and which results in stains on the ceiling and walls. It also promotes the growth of mould. Acrylic paint with good anti-condensation abilities can tackle this problem.
Difference between oil and acrylic paint
The basic difference between these two paints is the solvent the acrylic paints are water-based; they use water for the emulsion of the polymer that aids in binding. But the oil paints are oil soluble and use oil as thinning material. The drying time of oil and acrylic paints is significantly different. Oil-based paint takes more time to dry and gives more time to blend the colours. This aspect of oil paints can be used as an advantage for certain practices. The fast evaporation of the water-based acrylic paints can be lowered by using acrylic retarders. These retarders are the material that is added to increase the evaporating time of the paint. Oil paints require solvents like turpentine to clean up. Oil paint has higher pigment concentration as compared to acrylic paint. This is due to the small size of the oil molecules; oil paint can hold more pigment.
Components of acrylic paint
- Acrylic resin
Resin is the polymer from which the acrylic emulsion is formed. To ensure the good quality of the acrylic paint it is required that the resin used to make the paint should be of good quality.
The resin in the paint makes an acrylic polymer emulsion which acts as a binder. This holds the paint molecules together after the water evaporates. The binder present in the paint gives it long durability and handling characteristics.
The pigment is the dry powder material in the paint that does not get mixed but remains suspended in the paint and give colour to the paint. For every different colour, the pigment will be different. The pigment can organic, inorganic, natural, or synthetic. The final colour of the paint depends on the type of pigment used in it. Usually synthetic pigments are more durable and provides strong colours.
A good quality acrylic paint
To achieve maximum thermal insulation and resistance against condensation these following properties should exist in the acrylic paint. These properties make the paint distinct and strong.
The paint should be acrylic, for that a good quality acrylic resin should be present in the paint to make the acrylic polymer emulsion. This emulsion acts as a binder that holds the paint and pigments together after the evaporation of the water after application. A good quality resin is necessary for the acrylic paint.
Condensation of the water molecules makes the surface damp. This damp surface increases the chances of mould growth. The surface of the paint layer should be water-resistant and anti-condensation. Anti-condensation paint adds an extra thin layer of insulation that resists the condensation. This property of the paint prevents the formation of moisture and mold on the wall.
- Thermal insulation
The acrylic paint should be insulator that means it should prevent the flow of heat from one side of the layer to another side. For example, in summer the paint should resist the flow of heat to keep the room cool. This reduces the cooling load for the air conditioner. Similarly, the heating load of the heater is also reduced if the heat does not travel form the room to the outer atmosphere. This saves up to forty percent of the energy.
Other basic properties of the acrylic paint include; it should be permanent, insoluble in water after application, should take less time in drying, air dry by evaporation, washable with soap and water. After application hands, brush and plate should be washable with water. It should be odourless, inflammable, and fumeless. It should be easily available at a low price.
These properties of the paint are required for a good quality finish and long-lasting protection against humidity and temperature variations. Before applying the paint, you should read the instructions carefully. For example, stir the paint before use. The anti-condensation paint should be applied above the ten-degree centigrade temperature. For quick drying of the paint open the doors and windows for proper ventilation. Use protective sheets to cover the areas you do not wish to paint. One of the advantages of the acrylic paints is they are water-soluble so; they are safe to use in an enclosed environment.The colour selection of the paint is easy and depends on your judgment. Since the painting process is important and the beauty of the building after architectural design depends on the paint. You should choose the colour carefully that suits your building. You should test the colour of the paint before applying it on large scale. The paint selection process can be tricky, you can compare the available paint options in the market with each other or look for the above-mentioned qualities in the paint. But the website www.paintoutlet.co.uk gives you the best quality paint suitable for your need. There are a variety of paints available in good quality for your ease. All the paints are available in different colours so that you can choose per your desire.
