4 Simple Steps to Seal Bathroom Mirrors

That’s why I highly advise sealing your bathroom mirror edges using a quality bathroom mirror edge sealant, which will greatly prevent water from penetrating the underside mirror surface or the wood thus prolonging its life.

Let’s learn how to use it the right way!

How To Seal Bathroom Mirrors

Below are all the requirements, as well as a step-by-step process.

Requirements

• Painter’s tape
• A sandpaper
• Paper towel
• Silicone caulking
• Polyutherene

Step 1

Taping around the mirror’s perimeter is the first step of sealing your vanity mirror. The tape ensures that both the glass and wall are protected from damage.

If your mirror is framed with wood, add more tape on the outer parts of the frame perimeter.

Step 2

Use polyurethane to seal the wood frame with the foam brush. But first, you should stir it using a paint stick probably a wooden one then dip its tip into the mirror edge sealant.

After that, quickly apply a layer of polyurethane to the wooden frame.

Ensure it’s thin to avoid being too sticky then cover the framed mirror surface. The first time I tried it, I used too much. And trust me, you don’t want to deal with the mess this sealant can create.

Give the layer some six hours to settle then apply a second coat depending on your personal preference.

Step 3

Remove the tape from the wall and around the mirror surface after you are sure that the polyurethane has completely dried.

Step 4

This step is meant to take care of any creases that might have formed between the wall and mirror frame. You do this by applying a thin layer of silicone caulking. Make sure your finger is wet as you smoothen the caulking applied on the seams.

You may be wondering why you need to use a clear caulking silicone. It is because it is water-resistant and therefore you can be sure that water won’t penetrate under the mirror and cause mirror rot.

After this, use a wet paper towel to get rid of any extra caulking.

How Do I Protect My Bathroom Mirror from Moisture?

If you want your bathroom mirror to last and continue to show off your beautiful reflection, you must make sure that it is protected from moisture damage by cleaning regularly, sealing, and ventilating the bathrooms.

Below is how exactly you can do that.

Mirror cleaning 

A stained-glass mirror can be a major turn-off to a bathroom user. Mostly, it is caused by silver deterioration on the mirror surface. This is why you should ensure that your bathroom wall mirrors remain clean all the time.

The best way to go about mirror cleaning is by using a sponge, warm water, and a cleaning product that meets the safety standards.

As you do this, avoid spraying water on the mirror surface so that your fixture may not get drenched in water. This is why you should use a wet sponge and dry it with a dry and soft cloth.

Dry The Mirror and The Bathroom

I realized that if you dry the mirror and the bathroom every time you use it, you prevent moisture from building up close to the mirror.

At first, it may be difficult to always remember, but once you make it a habit, you’ll be surprised at how effective it can be.

Mirror edges sealing

I have discussed how to seal your bathroom mirror above. Sealing prevents water from settling between the mirror to wall space and causing damage.

If you use a quality mirror edge sealant, you will successfully prevent the formation of a black edge on it. This is because the sealing minimizes its exposure to water especially when cleaning it.

Ventilation

Lack of or poor bathroom ventilation is another disastrous cause of moisture formation. This is more so if you use hot water to shower. When the moisture builds on the surface of the mirror it condenses and causes damage [3].

However, you can get rid of the moisture by ensuring that the bathroom windows are opened for moisture exit. In case your bathroom is small, you can use a ventilation fan.
