Accidents, or just simple wear and tear, can stain, crack or chip even sturdy slate flooring. What is great with slate flooring, however, is that you can repair such damage with the help of tools and materials that can be bought easily at a hardware or home improvement store. When embarking in a repair project, consider these repair tips.

Tip 1 – Fill-in Cracks with Epoxy Glue
Small cracks on slate flooring tile should be filled in immediately, to prevent further damage to the tile. This repair tip, however, is not a guarantee that the tile has been put back to its damage-free state; this is just a temporary solution.
Epoxy glue comes in clear or opaque color. Color can be added to match the surface of the cracked slate tile.

Tip 2 – Repair Chips with Grout
Grout protects the tiles from chipping around the edges. Sand the jagged edge of the chipped tile. This is to create the illusion that the slate tile is naturally shaped as such, and the irregularity of its shape is just part of the stone’s unevenness in shape and texture. Buy a grout mix that matches the color of the old grout. Remove the old grout around the chipped slate (all four sides). Apply the mixed grout. The grout will fill-in the chip on the slate tile. With this procedure, you will not only repair the chip on the tile, you will also restore the grout to its pristine condition.

Tip 3 – Use Nail Polish to Color the Grout or Epoxy Glue
If you were unsatisfied with the color of the grout or epoxy glue, or that color did not blend well with the stone, you can use a nail polish to color the area. Nail polish works like a tinted varnish. It can give a glossy look, as though sealer has been applied the stone.
Select a color in tone and hue that is nearest to the stone’s natural color. Work on a small area to test if the color blends well with the slate’s color. If not, remove the nail polish with acetone. Remember to apply thin coats of nail polish to achieve good color consistency.

Tip 4 – Replace the Damaged Slab
There are times when the damage in the slate tile cannot be repaired by a simple epoxy glue or grout. When such is the case, you have to remove the damaged slab and replace it with a new one. This type of repair can also be done without the help of a professional. Careful attention, however, must be placed on the removal part: the damaged slab should not be forced off the floor, so as not to damage nearby tiles. Tip: chip the damaged tile on its center using a chisel and a hammer, to break away the slate tile into pieces.

Tip 5 – Prep the Area
Whether you plan to repair damage in your slate flooring with epoxy, grout or replace the damaged slab altogether, you have to prepare the surface for such repair activities. First, clean the area, specifically the damaged area with soap and water and allow it to dry completely. Second, strip it of sealer, paint and grease with acetone stripper. Lastly, sand the surface to ensure adhesion of epoxy, grout or mortar.




I worked on this beautiful Green Slate tiled floor just before Christmas but I’ve been so busy with other jobs I’ve only just go around to writing about it. The slate floor was installed in the hallway and kitchen of a property in the seaside town of Hastings and the owner was keen to have the

A client contacted me regarding their slate tiled floor which had only been down a few years and was now looking dull and uninviting. The slate tiles were laid in a herringbone pattern and Interestingly they had only been cleaned and sealed about a year ago by another company, but it has soon started to look dull again. Naturally my client was disappointed with the result, especially considering how new the floor was.

Slate Floor Before Cleaning Moseley

The property was in the Birmingham suburb of Moseley and as per usual I paid them a visit to survey the floor and conduct a test clean. From what I could see the sealer the previous company had used was already failing and wearing off, this left the stone vulnerable allowing dirt to become ingrained in the stone. We discussed the overall procedure and I completed a test clean on part of the floor which went well so the customer was happy to proceed. Whilst I was there, we also discussed the effects of different sealers I would recommend for the tiles so they could select one that would give them the look they wanted.

Cleaning a Slate Tiled Kitchen Floor

On the first day I applied a strong solution of Tile Doctor Pro-Clean combined with Tile Doctor Remove and Go, this was left to dwell on the slate while I cleaned up the grout with a stiff grout brush. I used this combination of products to ensure I stripped any coatings that may have been applied to the floor by the previous company and the original installer. With the grout scrubbed I turned my attention to the Slate tiles by scrubbing them with a black pad fitted to a weighted rotary buffer machine. The floor was then rinsed thoroughly, and the now soiled cleaning solution extracted with a wet vacuum.

The kitchen area was quite large, so I did the clearing in three section inspecting each section afterwards before moving onto the next. There were some areas where the existing sealer was proving stubborn to remove which were re-treated until clean. I discussed this with the customer who explained that the previous company had left a tin of sealer and advised them that they should clean the floor and then apply more sealer. This meant every time they did, they were adding another coat of seal and if the cleaning was not effective it would result in trapping dirt under the sealer! After spending most of the day cleaning, it was agreed to let the floor dry out and see how it looked next day.

When I returned on the second day, I could see there were still traces of sealer on some areas of stone and grout, so I decided to clean the floor again with more Pro-Clean but this time working in in with an abrasive 400-grit burnishing pad. This did the trick on the slate, but the grout needed a handheld diamond block to remove the seal. The whole floor was then rinsed and allowed to dry.

Sealing a Slate Tiled Kitchen Floor

Although previously we had discussed the different options for sealing the client wasn’t sure which one to choose. To help them decide I dried some of the tiles with a heat gun and applied different sealers to they could see the different between the matt and sheen finishes. The client decided on Tile Doctor Seal & Go Extra which helps bring the colour out in the tiles, it’s also breathable and has a nice sheen to it but slightly less so than Tile Doctor Seal & Go. I applied four coats as soon as the floor had dried.

I left the client with a bottle of Tile Doctor Neutral Tile Cleaner to help maintain the tiles appearance. The client was very happy with the results, thanked me for my hard work and commented that the floor looked better than the day it went down.
