How to Waterproof A Bathroom by Yourself

Bathrooms are our safe harbour for relaxation after an exhausting day at work. But we usually overlook its maintenance by giving more preference to other rooms such as kitchen and living room. When we talk about bathroom maintenance, we ignore its waterproofing.

Obviously, no homeowner would like water dripping out of the bathroom floors and through the ceilings on the living room floor. Most people, while renovating the bathroom simply tile or paint over the existing plaster work to reduce costs and completely forget about the waterproofing.

This idea of not considering bathroom proofing while renovating for saving money may just backfire and cost you double money by damaging the plaster work and tiling. In case you want to save money, then DIY bathroom proofing is the best option for you.

You can keep yourself occupied in the current uncertain scenario and do something useful in your free time.

The process is simple and requires few easy steps that don’t require any expertise. The following is the step-by-step approach for bathroom waterproofing:

Firstly, before starting with the DIY bathroom waterproofing project, make a note of all the points in the bathroom where there is a high probability of leakage.

Those points may include places like all the drainage line openings through the walls & floor, concealed water lines, and buried PVC or GI fittings, pipe joints, wall, and floor tile joints, etc. Focus more on these points while doing the job to make sure they are properly sealed.

Step-1: This is a step you need to do thoroughly. Clean the wall and the floor of the bathroom, removing all the dust and dirt. Also, make sure that the bathroom is completely dry and the walls and floors are devoid of moisture.

Step-2: Look out for a reliable DIY waterproofing kit. If you are clueless about which one to buy, then visit several hardware shops and look on the internet.

The following is a list of a perfect waterproofing kit:

  • Tanking membrane
  • Waterproofing Acrylic Primer
  • Tube of Neutral Core Silicone Sealer
  • Edging Tape
  • Gloves
  • Brush

Step-3: Take the tube of silicon sealer from the kit and apply it to all the corners of the walls and floor. Once applied, use your fingers to give it a final touch to make it smooth.

This will seal away all the pores if any. And the most important thing, wear gloves before doing this task.

Step-4: Be precise while applying the tanking membrane coat. Apply it liberally on all the internal corners using a paintbrush.

Make sure you paint on either side of the membrane and make the breadth of the patch approximately about 200mm.

Step-5: Place edging tapes along the length of each corner and smooth it down to bed it down into the wet membrane. Ensure that the tapes overlap bay at least 150mm.

Step-6: Now apply a second coat of membrane over the clog drains and around the taps and every other penetration through the wall or floor.

Step-7: Apply a coat of waterproofing acrylic primer all over the surface of the bathroom including the walls as well as the floor.

Step-8: Apply another coat of the acrylic primer in a direction that is at 90 degrees with the previous coat.

Step-9: The last step is to wait for at least 24 hours for the completion of the drying process. Once that period is passed, you can carry out any further work if needed.

After these steps, you can take some more precautions to avoid bathroom leakage. Apart from waterproofing, one should also make sure the slope of the bathroom floor is directed towards the drain to avoid water accumulation at one single point.

Also, select a waterproof paint for the ceiling and the walls if you plan to paint the bathroom and get a vent installed to get rid of the moist air in the bathroom. The moist air can result in moisture accumulating on the walls and can result in algae formation.

Keep all these factors in mind after your DIY bathroom waterproofing project and never worry about having leaking walls or ceilings ever again.
