Primer: Adding Life To Paint

Paint protects the surface of anything from various things like dust, grime, mold and mildew. It combats different environmental elements—snow, heat, direct sunlight, rain and others—those are responsible for damaging and destroying the surface especially, walls and ceiling of a home.


Painting is not that hard but getting the job done by self may not yield fruitful result because expertise matters a lot. The common mistake that DIY-ers make while painting is they do not consider priming.

Behind every successful man there is a woman, no doubt. Then what is there behind beautiful paint? Well, the answer is primer! Now you can imagine the importance of primer.

Priming is must before starting the painting job. Never skip it just because it adds bit to your total painting cost. Hence, I emphasize it. The life of paint is guaranteed by primer as a result it (paint) lasts longer.


Do you know what primer is?

It is liquid that is applied over the surface where you will be coating paint later. It prepares ground for color to stick. Primer contains 20 to 30 per cent of synthetic resin, 60 to 80 per cent solvent and 2 to 5 per cent additive agents.


Its importance

A coat over unprimed surface does not last long causing peeling and cracks because the surface is not in condition to hold the paint. It helps paint to stick on the surface. Any surface—dry walls, concrete, metal or wood—requires primer. Moreover, it is the feature of the primer that does not allow surface to soak paint which results less use of paint. Normally, new dry wall without primer soaks paint like sponge. Hence, primer saves your painting cost.

In addition, the interior and exterior of home definitely demands primer as it prevents different types of stains that are on the surface on the home. Water stains are easily hidden with primer. Also to block the boldness of previous dark color on the surface, we prime. Applying color over the primer will make the color glow further.


Preparation prior priming

First of all, sanding and scrapping prepares the surface where primer is applied. It is the property of primer that seals unfinished areas and reduces peeling chances. Furthermore, primer also hides minor defects on the surface like dents, marks, etc. If this is the second time you are going to paint, then priming is not required as it was done earlier. But if you are going to change the paint from oil to latex, then primer is necessary although it was primed earlier while oil painting.


Let’s talk about types of primer:

There are four types of primer—oil-based, water-based, metal primer and all purpose primer.

Oil-based primer Water-based primer Metal primer All-purpose primer
Used in such areas that is in everyone’s reach like door, windows, cabinets, etc. Applied in the area that does not come in constant touch Applied in metal prior to painting Ensures better adhesion of paints on the surface
Acts as barrier and prevents bleeding Best against grease and ink Creates protective film on the metal and reduce rusting chance Provide better protection of the surface where it is applied
Release strong odor Release least odor Release mild odor No odor and no VOCs
It is difficult to clean and requires paint thinner to clean Easily cleaned by water Cleaning metal primer is comparatively hard Easy to clean
