What is primer & Why primer is important before painting?

A primer is a coat that is applied before paint to provide extra stability and ensure better adhesion of paint, the durability of the material. It is also known as a preparatory coating applied before a paint. keeping its qualities in mind it can only be used as an underneath coating not instead of paint. In practice, if we look, the porous materials like cement, and wood require primer coating before painting. A primer is composed of resins, solvent, and some additive agents. In some, it may also contain polyethylene.

Nobody would like to see paint peeling out in the next few months of applying paint. So why not give a dose which makes it stronger.

Role of primer on wood– wood a natural growing product is born to absorb a lot of moisture and also has a tendency to be subject to attacks by mildew, fungi, and bacteria. Primer is a saver, and protector for wood. It will protect the wood from the above detriments and give longevity to the material.

Concrete and masonry primer- concrete and masonry surfaces have a diverse range, which can vary from 150 to 250 microns. This size depends on the type of sand used. The edges are very sharp which can lead to failure of paint within a few months of application. Thus, puncturing the film of the finished paint. PVC coating will serve the purpose of longevity, with less proportion of binder. The result will be a smoother surface. One important point to follow is that your primer should be Alkali Resistant. The cement which we use in concrete has some salt dissolved in it.

Role of primer on steel- corrosion is the biggest hindrance in terms of steel. Thus, a protective layer is needed to protect it from corrosion. Primer can serve the purpose well. Apart from this specific function, it should also provide the function of filling profiles and give a mechanical key to finishing paints.
