No, Decorating with paint only make your wall beautiful and if your wall is not protected from water its beauty will soon be snatched away. The thickness of waterproofing coating protect surface from seepage or leakage.

Ans: The roof is the most affected part of a building, directly impacted by rains. It is often the leakage through the terrace that causes severe dampness in the ceilings, thus spoiling the look of expensive interior paints.  

Terrace waterproofing is very critical, as a roof is always exposed to harsh weather conditions, climatic changes, and rains. The terrace surface tends to accumulate rainwater, which in due course starts seeping inside the slab. Over time, the deterioration of the surface will increase; leading to more damage.

Ans:

Following areas need to be given special attention while implementing roof waterproofing solutions:

• Pipes running over the roof or parapet wall
• Electric wires or cables conduits
• Rainwater drain outlets with proper size and number
• The threshold at the staircase door
• Water tank, dish antenna, split AC unit bases
• During surface preparation, an important thing is the fitting of drain outlets

Ans: Moisture around your home naturally seeps through porous concrete, leaving any material in the room soggy and damaged. To stop water from seeping through your concrete floor and ruining your room, take a number of steps with a variety of products to cut off water flow.

Ans: There are many contractors who say themself as waterproofing experts but actually they don`t. Today, there are many workers who even don`t have better knowledge or experience but registered themself on different websites and got calls forwarded from the site. 

A good company must have skilled workers and an experienced supervisor They do have better knowledge about materials according to the requirement. A good company may guide and suggest the best solutions. A good company gives a warranty for their works.  Don`t go at a cheap rate, if there are quality and durable work then it may cost you more but you will be happy with the work.

NOTE– There are no waterproofing works directly from dr. Fixit, Asian Paint, Sika, Berger, etc.. These companies sell leads to local contractors to complete the works.

Recommendation: Call an expert for inquiry/inspection first and then offer the project. 

In general, waterproofing gives life of 10 to 15 years. However, it depends on method of applying and materials proportion used. 

Minor joint sealing can be done in a day, but the caulk should have at least 12 hours to dry or in some cases 3 to 4 days before being exposed to water. 

It depends on many things like New or old construction; Work area; Terrace, Basement, Bathroom, Roof, Water tank, Swimming pool, Terrace Garden, how much the site has been damaged, etc.
