Painting a home gives it a fresh new look. At the same time, it protects the building structure, prevents fungus development, keeps insects at bay, and above all improves your mood, says a doctor fixit dampguard Kolkata expert.

In general, a fresh coat of paint should last for 7 to 10 years. But, what if your paint fails within a couple of years, specially when the cost of painting has increased badly in last decade? It’s too painful and very still very obvious – if you don’t know the exact reason.

So, let’s gather some basic yet valuable information regarding the reasons that paint fails in a building.

Imcomplete Surface Preparation

Paints are designed to be applied on a particular type of surface for best result. So, whether it’s a new building or old, interior or exterior, you need to prepare it as per the type of paint. The process includes:

Removing Old Paint

If you are repainting an old structure, you need to scrub through every trace of previous paint layer. Depending upon the age and number of old paint layers you need to use proper tools and experienced staff to make it perfect, says our senior doctor fixit damp guard Kolkata Mr. Kaushik Sarker.


Pits and holes on old building walls are common. It increases the painting time and decreases the outcome quality. So, do some patchwork to fill the gaps, holes and uneven areas of the wall.

Cleaning Dust

Scrubing old paint produces lots of dust which will prevent the paint to attach on the surface. So, you have to clean the area properly by washing it or by vacuuming it.


One never should paint on a moist wall. It will vapour after some time and will cause blistering of the paint. So, let it dry properly.

Choosing Right Quality Paint

Raw material quality is one of the most important parts when it comes to successful painting. And high price isn’t the only parameter to be confirm about the quality. You need to choose the paint based on the following  factors:

  • Surface Type: Concrete, wood, plastic, metal etc.
  • Environment: Humid, extreme cold/hot, excessive dry etc.
  • Position: Interior or exterior.
  • Light Reflection Factor: High or Low.

Another factor that is little different from these is the finish of the paint. It can be matt finish or glossy finish based on your painting theme design or your preference. Do note that, whatever you finalise should be verified by a professional painter, says a asian paints roof waterproofing Kolkata expert.

Selecting Right Tools

Tools matter a lot to complete a painting work properly. It’s not as tempting work as it appears. It demands high precision, vast experience and perfect use of right tool. You never should try any shortcut just to complete a painting project within deadline.

A major number of paints fail because painters use roller to speedup the project, where brush is appropriate. Similarly, sprayer can’t be the right solution if you don’t have much knowledge about the dos and don’ts. So, it’s big chapter which we would discuss in another future blog.

Following Right Method

Painting projects aren’t as simple as a homeowner generally thinks. There are several steps and every step takes time. As per one of our waterproofing contarctors in Kolkata, you never should interfere in the process, unless you have selected a novice painter. There are several other factors that could be included in this blog. But, following these points properly is enough to get good result, if not best.
