How to Grout

How to Grout

Step 1: Mixing the Grout
Read the instructions on the packet for exact instructions but in general mix the grout powder with water in a clean bucket. Add the grout a bit at a time and mix until you get a nice creamy consistency. Leave for 5 minutes before applying.

Step 2: Applying the Grout
Using your trowel, scoop some grout onto your squeegee. Apply this to the face of the tiles and work it into all of the joints (never use your fingers for this – use a grouting tool). Make sure you really push it into all of the joints so you don’t get any air pockets. Once you’ve covered an area, wipe off any excess. Continue until you’ve covered the whole wall. Leave for 10 – 15 minutes.

Step 3: Cleaning Up
Take your damp sponge and wipe over the tiles to take off any grout residue. Keep your sponge flat against the tiles so you don’t dig any grout out of the joints. Wash the sponge out regularly. Cover the whole wall and leave for 5 minutes. Repeat this process and leave for 30 minutes to an hour.

Step 4: Polishing Up
Take a dry, soft cloth and polish up the tiles to a clean shine.

Deep Cleaning Grout Black with Dirt in Wymondham, Norfolk

Earlier this year I was invited over to a property in the village of Silfield near Wymondham in Norfolk to inspect a Limestone tiled floor. Now I don’t usually quote my clients, but this is how the owner of the property had described the floor in the enquiry I received from Tile Doctor.

“Grout Black, where tiles have divots, dirt is encased,
plus no shine to floor, sealant non-existent.”

The problems listed were quite comprehensive and having had chance to survey the floor we found them to be quite accurate and really could not disagree with her comments! The Limestone tiles had been laid throughout the Kitchen diner and it was clear the sealer had worn off completely allowing dirt to become ingrained in the Limestone tiles and especially the grout which had turned black.

I understood from the owner that the grout lines should have been a pale cream colour rather than the black it was now, additionally the natural pitting in the Limestone was full of the same black contaminants. I ran a quick water test on the tiles to see if there was a seal present and it confirmed that if there had ever been one it was now completely compromised. The lack of sealer had allowed all liquid spills and dirt to soak straight into the tile making it dirty and exceedingly difficult to clean.

A large birthday celebration party had been planned and our client was desperate for the floor to be brought back to life beforehand. Although I couldn’t start immediately due to other commitments, it was able to return in time to get the floor clean for the party.

Deep Cleaning Limestone Tile and Grout

Our first job was to tackle the severe soiling trapped in the pits and grout lines. To do this a very strong dilution (2:1 ratio) of Tile Doctor Pro-Clean was applied to the floor and left to soak into the tile and grout for about 10 minutes. Then is was scrubbed into the tiles with help from a rotary buffer fitted with a soft/medium long-bristled nylon brush. The resulting slurry was then power rinsed with 60-degree hot water and extracted with our 400psi machine which jetted out all the black, oily contaminants from the grout and pits.

The floor was speed dried with the assistance of a large air mover. Once dry to the touch our attention was turned to filling the now exposed pitts in the Limestone tiles and two cracks with an appropriately coloured fast cure epoxy compound. Having allowed the filler time to reach full hardness, we ground down the excess material with 100 and 200 grit hand burnishing blocks in preparation for the next stage.

We find the best way to renovate the appearance of stone is to use a process called burnishing which hones the stone and beings up the polish. For this you need a set of 17-inch diamond encrusted burnishing pads. The pads fit the rotary buffer and are applied to the floor in sequence from 400, 800 and then 1500 grit using water to lubricate the process. The waster turns into a slurry as you work, and this is then rinsed off the floor with water after each pad and extracted using a wet vacuum. The floor was then left to dry thoroughly overnight with the assistance of our large capacity dehumidifier.

Sealing a Limestone Tiled Kitchen Diner Floor

Returning the following day, we thoroughly vacuumed the floor to remove any remaining powder and grit left from the previous day’s wet work before spray burnishing the surface with a Tile Doctor 3000-grit diamond pad. This last pad really beings up the polished appearance of the Limestone and gave the tiles a deep and rich shine.

This last pad is applied without water and so leaves the floor dry and ready to for a new sealer to be applied. Our sealer of choice was Tile Doctor Ultra Seal, it’s a premium penetrating sealer that soaks into the pores of the stone protecting it from within. Ultra-Seal doesn’t alter the natural appearance of the stone giving it undetectable protection from staining. Having allowed the sealed floor to dry with the assistance of our air mover, the whole area was buffed using a white buffing pad and a small amount of finely sprayed water to remove any light smearing before vacuuming once again to finish.

My client was delighted with the result and left the following feedback for us:

“Totally renewed two flooring areas in our house to what looks like a recently laid floor. I have already had so many compliments without even telling people it had been professionally cleaned! Nick and Sue are always very easy to have about, inconspicuous and hard working. Absolutely delighted with the outcome and would recommend without hesitation. Thank you so much!”

For aftercare cleaning I recommended Tile Doctor Stone Soap, its designed for cleaning polished stone floors and will help build-up the patina. It’s a neutral pH product so won’t prematurely erode the sealer like many tile cleaning products you find in supermarkets which are really sold for cleaning glazed ceramic tiles not sealed natural stone.
