Primer and its types

First impressions are greatly important to many of us and the very first impression that we get of a home or any property for that matter is through its paint job. A well-done paint job can enhance the aesthetics of your home, however, in order to do this, the walls of your home require a key element that's needed to enhance the paint life i.e. a primer. So what exactly is a Primer?

What is the use of a primer?

A primer is applied to the surface before the finishing paint coat. It acts as a foundation for the paint and its main job is to provide adhesion for top paint and make it stick to the wall. Ideally, if a primer is skipped and paint is applied directly on the surface, then the paint may not stick as well and the brush strokes might be visible on the final coat. A primer prevents the peeling and enhances durability of paint so your walls look beautiful for many years. 

Applying a primer on the surface provides it with protection and enables the surface to resist yellowing, blistering, flaking and more. Hence, a primer is crucial for the paint. Read about more details on influence of primer on walls and overall appearance at

Different kinds of primer

To get a complete understanding of primers, it's crucial to know the various kinds of primers available in the market. There are three types of primers in the market – oil-based primer, shellac primer and latex primer.

Oil-based primer

Oil-based primers can be utilised on various surfaces as they work well with both latex and oil paints. This kind of primer is ideal for the walls in order to resist ink stains, water stains and nicotine stains. Oil-based primers also make sure that no stains are visible after the paint coat is done. This is also why this kind of primer is ideal for use in places such as walls, doors etc which can be vulnerable to stains. However, one of the cons of oil-based primer is that it releases Volatile organic compounds, which if exposed in high concentration can cause harm to people. 

Latex primer

These are water-based primers that work well on concrete, softwood etc. In comparison to oil-based primers, latex primers are less brittle These types of primers also dry quickly and are not as likely to crack or peel. While not as efficient as oil-based primers in terms of covering stains, latex primers do cover minor smoke, crayon and other such stains. Such kinds of primers are good for prepping drywall and can also be cleaned easily. These primers also contain low or almost no Volatile organic compounds (VOCs)

Shellac Primer

Shellac primers are good for interior surfaces. These are the type of primers that are ideally used for sealing surfaces such as wood. Shellac primers have a dry time that is less than an hour and are extremely good at blocking stains. Such kinds of primers are good on surfaces such as plaster, wood, metal and more.

 

Which are the surfaces where a primer can be utilised?

1.    Wood is a surface where a primer can be used. As the wood absorbs moisture and can also suffer from fungi, bacteria etc, hence, applying a primer can be helpful. The application of oil-based primers on bare wood can be helpful in sealing its porous surface.



2.    Steel is another surface on which a primer can be used. As steel is subjected to corrosion, applying a primer can be helpful as it can act as a protection for the steel from the same.




3.    Similarly, in the case of concrete, it's best to use a primer before painting, as a primer can help cover up minor pores and can help resist efflorescence that is usually produced by concrete. Skipping on applying a primer can lead to your paint chipping away quickly.




In conclusion, it’s ideal to prime the surfaces before painting. Now that we know about primers, their types and their uses, it’s time to know which primer is the right one for you!

Modern White Concrete Architectures Across the World

  The term concrete is synonymous with strength, durability, and utility.

The colour white has been a source of inspiration from many Roman and Greek structures. In today’s date, white concrete is becoming increasingly popular with architects due to its pure look and uniform feel. It is created by combining lower iron and manganese oxide levels.
