Slate Tile Posts

I was recently asked to survey an unusual stone floor at a house in in Harrogate comprising of Slate inlaid with Granite. The client advised that it had not been cleaned properly for 20 years and wanted it renovating! It was now definitely overdue a deep clean and professional attention. Fortunately, having worked on these floors for many years I knew I could make a substantial impact and transform its appearance. Fossilized slate is a beautiful stone when cleaned and sealed correctly.

The owner confessed they had actually been sealing the floor every two years but without a deep clean first, so they were effectively sealing in the dirt each time. I discussed with them the process I would use to clean and re-seal the floor and we agreed a price to carry to out the work.

To remove the layers of old sealer and dirt used a set of Tile Doctor Diamond Burnishing pads. The pads are attached to a rotary floor machine starting with the coarse 400-grit pad which was lubricated with a dilution of Tile Doctor Remove and Go to help strip the floor of dirt and layers of sealer. After rinsing and extracting the soil I worked through the different grades of pads in sequence finishing with the 1500-grit and this time using just water for lubrication.

A set of diamond handheld burnishing blocks were then used to clean up the edges and corners where the large 17” pads struggle to reach. This ensures all areas are treated and free of dirt and old sealer.

The floor was then rinsed and extracted again to remove the remaining soil. I find a wet vacuum is an invaluable tool for this. The floor was then left to dry out overnight ready for sealing the next day.

I returned the next day to seal the floor, first checking with a damp meter that the floor was dry, and the moisture reading was below the acceptable level. These results were fine, so I had a green light to continue and seal the stone.

The customer wanted a shine on the floor so rather than apply a satin sealer which I felt wouldn’t adhere to the stone properly I decided to polish the floor further with a the last of the four burnishing pads which is a very fine 3000-grit pad. You don’t need to use a lot of water with this last pad just a small amount sprayed onto the floor using a technique we refer to as a ‘Spray Burnish’.

To seal the floor, two coats of Tile Doctor Colour Grow were applied. This is an impregnating matt sealer which intensifies the natural colours of this beautiful stone and provides long lasting durable protection.

Even I was impressed with the finished result but more importantly the client was over the moon. To keep the floor looking its best I recommended they use Tile Doctor Stone Soap which is pH neutral. You should always read the label in detail when choosing a floor cleaning product as many are too strong and not recommended for sealed stone surfaces as they will prematurely erode the sealer.

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.
