What is grout sealer?

Grout sealer is a product applied to the joints between tiles to protect them from water damage and staining.

It is important to apply grout sealer before grouting your tile project, as it will provide an extra layer of protection against moisture.

Different ways to apply a grout sealer

Sealers can be applied using different tools like a brush or roller. No matter what sealer you use, it should be allowed to dry completely before grouting. Here are a few different tools that you can use for sealing.

i) Spray bottles

If you apply sealer using a spray bottle, it can get on everywhere, and also easily spreads in the air. Since this method is handier, most DIY people go with this.

But spray can cause a lot of chemicals to spread out in the air and in other materials around it, leading you to breathe the chemicals in it. So, if you are going with this method, make sure to use a respirator.

ii) Applicator

Applicators are easy to use and are the most recommended method. Buy an applicator with a nozzle that fits rightly the size of your grout lines.

Rub it along the grout lines. If the grout lines are prominent and a bit bigger, then the applicator makes the task much easier.

iii) Brushes

Brushes are handy but if not done properly they can be a bit messier as well. First, dip the brushes in the sealer and apply them along the grout lines.

But you can choose different brush sizes that would be suitable based on the size of your grout lines.

How to apply grout sealer

Things you’ll need

  • A grout sealer
  • A clean cloth, brush, spray, or an applicator
  • A damp sponge
  • A bucket of clean water

Grout sealer is an important part of maintaining your tile and grout. Applying grout sealer can be a simple process if you follow these steps.

Step 1. Clean the area to be sealed. Make sure all dirt, soap scum, and other debris is removed from the surface before applying the sealer.

Step 2. Next, mix your grout sealer according to the manufacturer’s instructions.

Step 3. Apply the sealer. Using a clean cloth, applicator, or brush apply the sealer to the grout lines, being careful not to get any on the tiles themselves.

Step 4. Once all of the grout lines have been sealed, use a sponge to wipe away any excess sealer.

Step 5. Allow the sealer to dry completely before using the area again. Depending on the type of grout sealer used, this could take anywhere from 24 hours to a few days.

This step will help protect your grout from staining and make it easier to clean in the future.

That’s it we are done!

Tips for applying grout sealer

a) When applying grout sealer, be sure to read the instructions on the label carefully. Some products require that you dilute the sealer with water, while others must be applied undiluted.

b) Before applying grout sealer, it’s a good idea to clean the grout with a mild detergent or household cleaner. This will remove any dirt or residue preventing the sealer from adhering properly.

c) To apply a grout sealer, simply dispense it onto a clean cloth or brush and spread it evenly over the surface of the grout. Be sure to work it into all of the nooks and crannies for full coverage.

d) Allow the grout sealer to dry completely before walking on or using the area. Most products will need to cure for 24 hours before they’re fully effective.

When to re-seal your grout

It’s essential to periodically re-seal your grout in order to keep it looking its best and prevent staining.

Depending on the type of grout you have, and the amount of traffic in your home, you may need to re-seal every few months to every few years.

To test if your grout needs to be re-sealed, sprinkle a few drops of water on the surface. If the water is quickly absorbed, it’s time to re-seal.

Alternatives to grout sealer

There are a few alternatives to grout sealer.

One is to mix a 50/50 solution of vinegar and water and apply it to the grout with a clean cloth.

Another is to make a paste out of baking soda and water and apply it to the grout with a toothbrush.
