What is Grout Colour Sealing & How Does It Work?

Here’s how grout colour sealing works and why you should get it

What is Grout Colour Sealing?

Over time, grouts can become dirty and wear out in colour due to wear and tear. Grout colour sealing acts as a protective layer that prevents the grout from being so easily affected by wear and tear over a long period of time, eliminating the need for frequent maintenance. Grout colour sealing can also help to preserve the new look of any surface.

How Does It Work?

After thoroughly cleaning and rinsing of both wall and floor grout, we administer our exclusive breathable Colourseal.

This exceptional sealer serves a few purposes:

1. To bring the grout back to it’s original uniform colour.
2. To change the colour of the grout (to give a different look to the tiled area).
3. To provide a water and oil resistant coating to the grout.

  • Can you repair a leaking shower?

    This depends on the leak and the construction of the shower.

    If a shower is leaking through a wall into an adjacent room, there is a failure with the waterproofing membrane behind the tiles. This cannot be repaired without a major deconstruction of the shower and can be very costly. Simply replacing failed grout and silicone, which may look like it is waterproofed the area, is not a solution that can be guaranteed.

  • What should I clean my grout with?

    Unless your grout has been sealed properly there is nothing that will keep it clean. Many people resort to bleach or even acids to try and remove stains which will, in fact, damage the grout. GroutPro specialises in sealing the grout so that mild eco-friendly cleaners are all that is needed to keep it looking in tip top condition. If your grout is already stained we can recolour it and seal it with our Colourseal sealer.

  • How long does silicone stay mould free in a shower?

    There is no easy answer to this question as it comes down to your daily maintenance process. Moisture, heat, and soap residue are what mould thrives on, so in order to minimise growth we recommend ensuring a good extractor fan is used during showering, and that you wipe your shower dry after each use. This removes the conditions that mould needs to grow.
    We have found that silicone in a shower typically requires replacement every couple of years.

  • What kind of grout is best for a wet area such as a shower?

    Epoxy grout is recommended in wet areas as it is waterproof and much more resistant to staining. We regrout shower bases with Epoxy to provide the longest lasting solution. Grout on shower walls can be protected using our Colourseal grout sealer, which provides similar protection to Epoxy grout.

  • Can you fix a broken tile?

    This really depends on the extent of the damage. Small chips and cracks can be disguised so they are much less noticeable, but larger damage requires us to replace the tile.

  • Why can’t I get the water marks off my shower glass?

    Water spotting is caused my minerals such as calcium, lime, and iron in the water supply fusing to the microscopic pores of the glass. This happens when the water droplets are left on the glass after showering – the water evaporates leaving the minerals. Over time these minerals block the clarity of the glass. Specialist abrasive products (and a lot of elbow grease) are required to remove these minerals without damaging the glass. In most cases we can restore 80%-90% of the clarity, but occasionally the glass is unable to be restored.
    The best way to minimise water marks is to dry the glass after each use.
