Why Waterproofing In Bathroom Is Important?

Although water is an essential element of life, but it can also be incredibly destructive when left unchecked. Bathrooms are particularly susceptible to water damage due to their high moisture levels and frequent water usage. The moisture and dampness due to water are often the causes of various constructional mishaps; hence, without waterproofing, one could face many unlikely consequences. Along those lines, here are some of the major reasons why waterproofing a bathroom is crucial. 

Prevents any structural damage: As mentioned, the moisture caused due to water often leads to the deterioration of bathroom structures over time. It can weaken walls, floors, and ceilings, compromising their integrity and safety. Waterproofing prevents moisture from seeping into these spaces, thus preserving the structural strength of your bathroom.

Prevents from harmful microorganisms: Bathrooms are prime breeding grounds for various harmful microorganisms due to their damp environment. These microorganisms not only pose health risks but also contribute to the degradation of surfaces. With waterproofing, one can create a barrier against moisture and prevent harmful microorganism growth.

Cost-Efficient: Regular maintenance and repairs resulting from water damage can even put a hole in your pocket. Waterproofing works like an investment that can save you significant expenses in the long run by preventing the need for extensive repairs. And going as per the old saying, a penny saved is a penny earned, eventually making it cost-effective. 

Enhances longevity: Waterproofing extends the lifespan of bathroom fixtures and finishes. Tiles, grout, and other materials are less likely to deteriorate when shielded from constant moisture exposure.

Health and Hygiene: Last but not the least, and arguably the most important factor. Adequate waterproofing reduces the likelihood of water stagnation, which can lead to foul odors and bacterial growth. A dry bathroom environment contributes to better indoor air quality and overall hygiene.

Why Silicone Sealant Is Perfect For Waterproofing Bathrooms?

Using silicone sealant for bathroom0 is a smart move, and there are ample reasons behind it. But for your convenience, we have listed some of the major pointers that make silicone sealant for waterproofing the perfect choice.

Flexibility: Following the curing process, silicone sealant retains its flexibility, enabling it to accommodate the inherent shifts and vibrations within bathroom structures. This adaptability is particularly vital in settings where surfaces could undergo variations due to temperature fluctuations or settling.

Water Resistance: Silicone inherently possesses strong water-resistant properties. It efficiently repels water, preventing it from seeing it into joints, crevices, and corners. This attribute establishes it as an optimal material for effectively sealing regions surrounding sinks, bathtubs, showers, and other moisture-prone locations.

Prevention of Mold and Mildew: Silicone’s innate resistance to water also renders it unwelcoming to the growth of mold and mildew. Its sleek and non-porous surface acts as a deterrent, prevents these microorganisms from finding a foothold, contributing to a cleaner and healthier bathroom environment.

Strong Bond: Silicone sealant exhibits excellent adhesion to various surfaces commonly encountered in bathrooms, including tiles, glass, ceramics, and metal. This robust bonding capability results in a dependable seal that withstands exposure to water. And therefore, most commonly, you might notice people using silicone sealant for tiles.

Ease of Application: Silicone sealant is conveniently available in user-friendly tubes, facilitating precise application. It seamlessly fills gaps and joints, ensuring comprehensive coverage and efficient waterproofing.

How to Use Silicone Sealant for Waterproofing?

Gather Materials: You’ll need silicone sealant, a caulking gun, a utility knife, masking tape, and a cloth for clean-up.

Preparation: Ensure the surfaces are clean, dry, and debris-free. Remove old sealant using a utility knife, and clean the area with a suitable cleaner. Apply masking tape along the edges of the joint to create clean lines.

Cut the Nozzle: Cut the nozzle of the silicone sealant tube at a 45-degree angle. The size of the cut will determine the thickness of the bead of sealant.

Load the Caulking Gun: Load the silicone tube into the caulking gun and secure it in place. Press the trigger gently until the sealant begins to flow.

Application: Hold the gun at a 45-degree angle to the joint and apply an even bead of sealant, following the path you want to seal. Apply steady pressure on the trigger for consistent application.

Smoothing: Immediately after applying the sealant, use a moistened finger or a silicone tool to smooth the bead, ensuring it fills the joint completely and has a neat finish. You can even use soapy water to moisten the finger, dip your fingers in the soapy water, and smoothen the silicone sealant to ensure it does not stick on your fingers. 

Remove Masking Tape: Carefully remove the masking tape before the sealant cures to create clean edges.

Curing: Allow the sealant to cure according to the manufacturer’s instructions. Curing time can vary depending on the type of sealant, humidity, and temperature. Most of the sealant takes up to 24 hours to dry. 

Clean-up: Wipe away any excess sealant using a cloth dampened with a silicone-friendly solvent or soapy water.

Avoid Water Exposure: While the sealant cures, avoid water exposure to ensure the best results.

In Closing

Waterproofing your bathroom is an essential measure to protect your home from the damaging effects of water.
