How to do waterproofing in the bathroom?

To make an exterior and interior of a surface secure from the damage caused by water leakage, rainwater, surface water, and damping or humidity – Waterproofing is a vital practice to be done after completion or in between the construction.

The bathroom is one of the main parts of any house and it must be given special care for keeping it safe, secure, and hygienic. Wet areas need to be properly waterproofed because walls, floors, and tiles can be easily influenced by running pressurized water of unsteady temperature.

Mainly, the cemetery areas where water runs the most demands proper care for leakage and humidity such as bathrooms, kitchens, gardens, and field houses. Every type of surface can be sealed at any time with the full faith of the respective company. Whether a bathroom is under construction or needs modification – sealing is a major necessity.

5 simple steps to waterproof a bathroom with ease

Step- 1: Prepare the surface

The very first step before applying the coat for the waterproof layer is preparation. Pick all the goods placed in the bathroom such as a bucket, soap, shampoos, tub, etc. This will open the surface and the process can be done smoothly and easily.

Step- 2: Clean the bathroom

In case you are modifying a bathroom dust off the dirt particle, grease, acid, or any unwanted mud stuck at the surface. Throw water over the floor with full pressure. Make use of brushes, wipers, and detergents for giving a deep cleansing to a bathroom. Give special attention to the corners and edges as most of the soapy layers gather at this particular point.

Step- 3: Measure the area

The Second and the most important step in fitting a waterproof layer is ‘measurements’. Examine the complete area to be coated and write it down in a notebook – this will help you in estimating buying material according to accurate dimensions. Suppose you want to coat the floor of the bathroom – calculate the length and breadth of the floor. Double-check the recordings if required.

Step- 4: Choose a suitable method to operate

Fix the waterproof sheets in the bathroom

  • You can go with any method of waterproofing as per the requirement. To fix sheets of any type in the bathroom just go through the following steps
  • Sheets are self-adhesive and can be applied simply to the walls and floors of a bathroom.
  • Apply the primer or grout for extra satisfaction or in case you feel they have low adhesive strength.
  • At the corners of the floor and walls, apply sealing tape. Also, seal plumbing pipes and every fitting.
  • It is the perfect time to start attaching sheets to walls- remembers to fix the membrane upside down. Carefully apply every layer of the sheet along with the tapes.

Apply cementitious waterproofing membrane in bathroom

This type of waterproofing is mainly done while constructing the apartments and multiple-story buildings to provide safety from water entrance through roofs and floors. Follow the given steps to understand the idea behind adding a waterproof coat of cement.

  • Deeply clean and chip the waste material attached to the required surface.
  • You can use a trowel and any grinding tool for cleaning purposes – do not settle for even a little dust.
  • Wash the area with cold water and dust off the excess with a broom.
  • Now, the portion is all set for making an incredible change.
  • Mix the sealant to the cement – stir the mixture until they are bonded strongly with each other.
  • Using a brush, apply the substance to walls and floor just like paint. Cover every corner with perfection.
  • Apply 2-3 coats and let them dry.

Step-5: Paint or tile the surface

Once the waterproof coatings are dried up properly, apply your favorite shade of paint on the walls and fix the tiles on the floor. Give a smooth finish to texture by applying lacquer.


Even though the bathroom itself relates to water and water running taps, shower, pipes, drainage, tubs, and sink – it still deserves to make excess moisture-proof. The tiles, walls, floors, and plumbing area must be properly shielded with a suitable membrane. The life span of the entire building will be enhanced.

How to do waterproofing of terrace?

Waterproofing is a procedure to make a structure unaffected by the presence of water. Regardless of what kind of structure you are talking about – take a special account of waterproofing in each case. A layer of protective compound is constructed between the surface and the exterior atmosphere to make it water bearable.

A flat base surface or roof is known as a terrace. Structural designs that are flat and have no curves require a secure membrane to make a shield from water more than any other kind of surface.

Today we will understand why a terrace need waterproofing does and how can you do it simply within few hours!

Why does a terrace need waterproofing?

Flat surfaces such as terrace and rooftops need extra attention and urgency for making them waterproof. When water runs on these types of plain constructed areas it goes rapidly within the material because of the absence of any curve and bumps. The water from the terrace can travel frequently even if the drainage system is fitted.

To protect the incoming possible damage from water – a protective layer of liquid or solid material is coated over the top of the terrace. The whole procedure is done by experts but can be performed voluntary if you understand the concept completely. Read the below guide to know how the terrace waterproofing is done within few hours.


Choosing the right method for applying a waterproof surface is an important part of construction because the rooftop protects the whole base and rooms that guards the whole building against exterior environmental conditions.

1. Clean the roof area properly

First thing first, if a building is already built and needs modification then cleaning and washing off the dirt is a must. Now go and clean the unwanted mess spread over the surface. You can make utilization of cleaning tools such as a shovel, trowel, scrappers and anything else you wish to make the process easier as per your need.

Properly clean the old settled particles so that they do not interrupt coating later.

2. Wash the terrace with water

In the Next step, clean the rest of the dust and dirt particles with a fine pressure of water. You can use a water pipe for making the procedure handy and quick. Remove old and damaged surface or paint present on the roof. At the end of cleansing, you may see various cracks and breaks on the upper portion of a surface.

3. Repair the cracked areas

Examine the rooftop carefully and look for the crack areas and points on the top. Quality sealant and crack filler fix the broken gap between the cemented materials. Moreover, the invisible gaps and cracks can be filled by evenly applying a layer of silicon liquid and grout on the required spot.

4. Re-plaster and Break the required cracks

After filling the minor cracks – move forward to the major gaps that can be either filled or make even with the help of a grinder. Using polymer and fibreglass materials, the re-plastering can be done easily.

5. Use damp proof liquid on the surface

Let the cracked area dry for 2-3 hours and also remove the extra coating. Now, take a damp proof liquid to make a base for the application of waterproofing layers. This element will ensure the safety of basic damp and humidity caused by atmospheric changes.

6. Apply the protective film or layers of coating

Decide what kind of method you prefer for making protective layers. An adhesive sheet, as well as liquid membrane, works best for huge and open terrace areas. They can be attached within a limited timing in simple ways. Moreover, your mason will suggest what suits the best for an entire terrace.


Among the numerous kind of structures, designs, architectures and buildings – flat surfaces such as terrace and rooftops demands much more focused waterproofing. Try to proceed with the same while construction works rather than following the waterproof plan after construction. It will save a lot of money, damage and will give you a peace of mind.

How to Do Waterproofing?

To make a coating or layer for making it protected from the water can be decided depending on the type of place, construction area, surface and structural design of a building, However, all kind of waterproofing methods can give valuable results when operated will proper planning and fitting.

Weather changes without stability and during rainy seasons –

people face issues of dripping roofs, walls and entering surface water to the floors. Such conditions can be aided by choosing an accurate combination of layers. An expert individual with a good knowledge of construction can transform a building from ordinary to incredible just by putting his efforts to make it waterproof.


The process of waterproofing is both simple as well as complicated depending on the method we are using for making layers on the surface.

Generally, multiple coats of quality materials are added which acts as a protective film.

The coating material can either be directly applied or mixed into the paint that regulates the temperature and surface tension to keep out the molecules of water.


Many advanced methods with high-end technology support structural designs from damping. Some techniques are simple while other is complicated. According to our team of experts, each method has its uniqueness that cannot be denied. Read below the top 5 types of waterproofing methods –


Sheet membranes are a thin and durable layer of watertight materials applied on the existing tiles, marble, bricks, and cement walls to make sure water does not cross the structure. The huge rolls unbind together to make a layer to avoid leakage.

  • The advanced and effective method for ensuring water resistance is the method of utilizing sheets.
  • Sheets are nearly self-adhesive and can be attached easily by heating the bottom part of a sheet.
  • It is the most trusted membrane used by manufacturers and referred by civil engineers.
  • Thermoplastics and vulcanized rubbers are important elements.

Various Applications of Sheet Waterproofing

Rooftops, industries, walls, water tanks, hilly- areas `


Cementitious plastering is the easiest and time-efficient method for waterproofing any area of a surface. The best thing about this method –

it is easy to operate with, anybody can apply coats of cement to make a wall or base waterproof.

  • Using cement as a water-resistant element is known as one of the cheapest ways to shield a home from unwanted humidity.
  • In this method, thick coats of cement are applied on the plaster of walls, roofs, and basements.
  • Applicable for both positive as well as the negative side of waterproofing systems.

Various Applications of Cementitious Waterproofing:

  • It is used in the construction of dams, sewage and water treatment plants.
  • Railways systems, government property and bridges popularly use cement to form a water protective layer.


Using a Liquid membrane for layer formation is my favourite method of shielding a surface because working with rollers, brushers, and paint boxes, spray bottles and trowel is a fun activity.

  • A liquid is mixed with paint and then applied to the necessary portions.
  • The rubber acts as the primary element in a liquid waterproofing membrane.

Various Applications of Liquid Waterproofing:

  • In construction, liquid waterproofing is a common and easy way to protect walls and roofs from damping.
  • Specially used in bedrooms, bathrooms and kitchens.
  • The calibre to maintain dryness between surfaces depends on the polymer used in liquid and paint for coating.


Sodium Bentonite is the main element that gives rise to the name bentonite membrane.

A grey coloured clay having the consistency of the powder is taken from the various parts of the earth surface. Thus it is a natural way of sealing the exterior of a building.

By this time, bentonite keeps on swelling by absorbing water until it reaches 15 times its original size.

The external walls and basements work best when coated with bentonite as it completely blocks the entrance of water.

Various Applications of Bentonite membrane

Irrigation canals, dams, bathrooms, toilets, gardens, advanced well systems and many more.


Polyurethane is the combination of functionality and beauty –

it is flexible, eco-friendly, easy to apply and does not create a mess around the surface. Leaving a smooth and stronger texture on the flat areas, it protects the various kind of material from getting wet and damp.

  • Typically done on flat roofs and the areas exposed to the outer environment to strongly resist the leakage.
  • Polyurethane liquid waterproofing is expensive but gives marvellous results.
  • Always remember to apply the layers of polyurethane only when the base surface is properly dried.

Various Applications of Polyurethane waterproofing

Plain floors, roofs, walls


Waterproofing can be done in any suitable way depending on the choice of a builder and the need of the time. The major thing that matter is the objective of the structure that needs to be covered. For interior and exterior of homes, polyurethane membrane and liquid membranes are considered as best while for huge and massive monuments bentonite clay and sheets work perfectly fine.
