Product Review of the Grout Shield Grout Restoration System from Kilrock - How to Make Re-grouting Your Bathroom, Shower or Kitchen Super Easy
Product Review Summary: Re-grouting the wall or floor tiles in a shower, shower room, bathroom or kitchen was one of the worst jobs there is. The old grout had to be raked out to a certain depth, then the new grout had to be mixed and applied. Now the old grout stays exactly where it is, is cleaned down a little and the new Grout Shield Grout Restoration System from Kilrock does the rest. It is a unique product which will be very popular with both home-owners wanting to spruce up their bathroom or shower room and the trade tilers for whom regrouting bathrooms has been a nightmare.
On Site Test of the Grout Shield Restoration System
We took the Grout Shield Grout Restoration System into a couple of bathrooms to see just how it worked. The results were excellent and you can see how and why by reading the full review below and watching the Grout Shield video at the bottom of this page. Let’s have a look first at what happens in the shower or bathroom to make the tiles so dirty.
Shower and bathroom wall tiles get stained, over the course of time, with gallons of dirty water flowing over them day by day. The dirt itself, plus spores of mould get into the grout. The process starts with mild discolouration which starts by going a little beige, then a bit browner until, before we know it, they are full on black!
Removing old Tile Grout
Before Grout Shield, the only solution was to rake, or scrape out the old, dirty grout, and replace it with a new grout mix. Fortunately with the new Grout Shield Restoration System, this method is a thing of the past.
Raking out grout is a particularly difficult and horrible job. Usually a Grout Rake tool is used. This tool has a small, steel blade with fine carbon grit stuck to its edge. The carbon literally wears away the grout as you rub it up and down in the grout joint. You can see a video on how to use a grout rake here.
Grout Removing Tools and Blades
Of course, it was not long before people started to realise what a horrible job this was and their minds started to work on alternative solutions. It is possible to use a multi tool, with a carbon or diamond blade, to remove the grout from the wall and floor tile joints mechanically. However, one slip of the blade and the tile is ruined. It is then quite another job removing a tile from a bathroom or shower room wall!
Using a Grout Pen
Then the Grout Pen was invented. This was amazing as, after a quick scrub of the tile joints with bleach, you could simply draw nice new white grout lines on. However, as the “ink” within the grout pen was simply applied on the top of the existing grout it did not actually become part of the joint, it just sat on top. The result of this is, that after a few showers, the new grout covering just washes off. Back to square one!
Leave Grout in Place with Grout Shield
How Grout Shield Works
Unlike grout pens and other paint on grout restorers, Grout Shield actually chemically bonds with the existing grout to make sure it stays in place. It is not a colour sitting on top of existing grout lines, it is a colour which has actually bonded with the grout underneath. Grout Shield can last up to 10 years, regardless of how many showers and splashes the wall and floor take!
Instructions for Using Grout Shield
It is important these instructions are followed. Grout Shield relies on a chemical process to work properly and longevity will depend on how well these simple instructions are followed. You can see the process in action in the video below.
Give your tiles a general clean first. The job will be much harder if you are simply wiping dirt and grease back into the joints
Check all the gout joints finish below the level of the surface of the tile. If they don't, use a scraper or grout rake to remove everything that sticks up above the tile surface
Use the Grout Shield Pre Cleaner spray to spray a few grout lines at a time. Leave the Pre Cleaner on for 2 minutes, then scrub with a nail brush or similar. You will see the dirt and mold start to come off. The Pre Cleaner here is not just cleaning the grout. It is opening the pores of the grout to receive the colour seal. The dirt and grime just blocks these pores and for Grout Shield to be at its most effective, it needs to sink in a little
Dry the tiles off with a towel
Make sure the nozzle of the colour seal is clear and, doing one or two grout lines at a time, squeeze the colour seal out of the bottle into the joint in a long thin smooth line. Do not allow too much to come out, it should not “blob” and with a little bit of practice you will be able to get a nice thin line of colour seal into the joint.
Use the small brush supplied and brush (do not “scrub”) colour seal into the joint. When doing vertical lines, brush upwards
Brush in one direction if possible. This may not be possible when butting up against other walls and shower cubicles etc. so don't worry about going the other way for short sections
There will be some colour seal on the tiles. Where the joints are deep, use the orange cloth to brush across the tiles and joints. This should be done diagonally so you do not wipe the colour seal out of joints
Where the joint is shallow, use the red scraper to clean the tile. This ensures you have left all of the colour seal on the grout line
Leave for 20 minutes and grab a mild multi surface cleaner, with a soft, dry cloth to buff up the tiles
The treated area will be ready for full use in three hours
Grout Shield Coverage
Obviously the larger the tiles, the less number of joints there are. The following table shows you the coverage you can expect from a bottle of Grout Shield colour seal.

Docs Opinion of the Grout Shield Restoration System
It took me a while to get used to the idea, and to be honest I had to redo four of my grout lines, as I had got the grout everywhere, but after half an hour or so I had it cracked. Brilliant.
If you want to rake out grout and re-grout your bathroom or shower room after finding out about Grout Shield then, my friend, in my opinion, you are bonkers. Grout Shield will go on to be one of the best assets in a builders or plumbers portfolio, 5 stars all the way!
