What is grout sealer?

After you’ve had your tiles installed, you’ll want to protect the areas in between.  This porous surface area is known as grout.

Grout sealer protects this area from becoming damaged or discoloured.  Grout is porous, and over time it can absorb particles of dirt or other materials.  To protect grout from becoming discoloured, it helps to seal the grout.

Using grout sealer is about cosmetics.  Your grout surface will rarely be at risk of damage from acids or other corrosive substances.  However, cosmetic reasons alone are often a great motivation to seal your grout.

You have probably been into an old house or public facility where the areas between the tiles have become yellow and discoloured, or worse, stained with mildew.  This discoloration occurs because the grout has not been sealed.

When should you use grout sealer?

If you’ve just had an area of your home retiled, you can apply grout sealer once your grout has completely dried.  This will help you to keep your grout looking fresh and clean.

If you have applied grout sealer in the past, but it is beginning to wear off, you can reseal it so that your tiles stay clean.

Grout sealer is most important in areas which are moist or damp.  These areas can often accumulate mildew.  Bathroom and kitchen floors are other important areas where grout sealer could be applied.  These areas look best when clean and fresh, but often yellow over time.

Using grout sealer from the start will cut down on your maintenance work.  Without using sealer, it can be hard work to clean the areas between your tiles.

This can be done, but often requires the use of a scrubbing brush and harsh chemicals.  Once you’ve sealed your tiles, you’ll simply be able to wipe over them with a cloth.  This will help you to keep your newly laid tiles looking fresh from the very beginning.

If you’ve used an epoxy based grout, you won’t need to seal your grouted areas, however.  Epoxy based grout naturally resists liquids.

However, it is usually only commercial tillers who use epoxy based grout, and usually for spaces where there is high traffic or harsh cleaning chemicals.  Most tillers won’t use epoxy based grout in your home, but you could always check.

What types of grout sealers are available on the market?

There are two different types of grout sealers available on the market.  Once you know the difference, you shouldn’t have much difficulty finding the best grout sealer for your needs.

A penetrating grout sealer gets into the porous spaces within the grout, sealing them off.  This will prevent mildew or other fungus from getting into the surface of your grout.  When you use a penetrating sealer, it will darken your grout.

You will often only have to apply a penetrating sealer to your grout once in a very long time.  Penetrating sealers last up to 15 years before your grout will need to be resealed.

However, once your sealant has lost its effect, you will have to strip it in order to reseal your grout.  Grout sealers cannot simply be reapplied by painting over the old product.

Non penetrating sealers are simply painted over the grout.  They don’t penetrate the surface, but lie on top of it, forming a waterproof surface.

This will protect your grout.  Over time, they may discolour as well as chip or wear away, which will leave your grout vulnerable.  As a result, they need to be checked regularly, and particularly when used as a shower sealer.

Non penetrating grout sealer needs to be replaced every 3 to 5 years. You can simply strip off the old grout sealer and replace.  It may take time, but will once again offer up protection for years to come.

In between non-penetrating and penetrating grout sealers, there is a middle ground.  Acrylic grout sealers are non-penetrating and are painted onto the surface of your grout.  However, they are much stronger.  They are, however, harder to remove when needing to be replaced.

The best tile grout sealer for your home will depend on your needs.  If you are undecided, however, and have tiled your floors or showers, we recommend using a penetrating grout sealer.

This is the best grout sealer if you would like to create an excellent long term barrier against mould, mildew, dirt and fungus.

If you have chosen to use a grout waterproofer, you may be wondering how easy it is to apply.  Let it be known that applying grout sealer is a tedious job.

The smaller your tiles, the more time consuming it will be.  If you have installed large tiles, however, your grout water sealer will be easy to apply.

Spray sealant is often an easier choice if you have a great many small tiles. If you have installed a wall of mosaics in your shower floor, for example, and fear that it will take a whole weekend to seal your grout, you could always use a spray on shower floor sealant.

This easy grout sealer will save you a great deal of time and effort when compared to using a brush.

How long should you wait before using a grout sealer?

After your tiles have been installed, you will need to wait for your grout to dry completely before using grout sealer.

Moisture within your grout will prevent the sealant from soaking in.  Keep your room warm and dry to aid curing.  Then use a good grout sealer once your grout has completely dried.
