Slate is a wonderfully versatile stone that can be finished with a variety of finishes from rough texture, honed smooth or polished. We are very fortunate in the UK to have easy access to Welsh slate, recognised since roman times as the premium quality slate as it is harder wearing than most other slates.
However, Welsh slate also has a premium price and lower cost slate tiles are available from around the world. So if you are thinking of installing a slate floor, you need to research the source of the slate and check if it meets your needs.
Brazilian slate is quite hard, so it wears well. Chinese and Indian slates are softer, so they wears quickly and can flake from foot traffic. As with most things, you need to weigh up the cost against the characteristics of the stone.
Whilst slate has a low porosity, it will still absorb water and oil based spills, leaving annoying marks. So it is always better to apply a sealer on the tiles to help maintain their appearance
We are mostly called in to clean slate when it has layers of sealer with ingrained dirt, so the finish looks dull and dirty. So the cleaning starts with getting all the layers of old sealer off the floor.
We do this by using specialist strippers to break down the sealers and get them for rinsing off. We apply the stripper and leave it to do its work for up to two hours.
Most of the slate we clean is rough surface, and the sealer can be quite thick in the crevices of the stone.
So we use a rotary brushing machine and various brushes to make sure we have for all the sealer off the stone.
We may need to apply a second application if there are a lot of old sealer on the floor.
This is an important step as patches of old sealer will show up as dirty patches under the new sealer.
To make sure all the old sealer and slurry is removed from the surface of the slate we use pressurised hot water “rinse and capture” equipment.
The enclosed cleaning head sprays clean pressurised clean, hot water onto the stone to release the slurry. This means there is no overspray to mark your walls of other furnishings.
The equipment immediately vacuums the slurry away out of your home into a rinse tank in our truck.
After checking that all the sealer is removed, we use high speed air dryers to help fry the floor ready for sealing. If we find that lose grout has come away, we can re-grout the areas.
Once the floor is dry, we apply a sealer to help protect the stone from spills and make it easier to keep clean. Leaving a beautiful slate floor ready for years of use.

There are two issues to consider.
1. The location of the slate floor
The main reason a you should think about sealing slate floor tiles is the chance of oils and other liquids being spilled on them.
If the floor is in a kitchen or a bathroom, or anywhere in a home for that matter, there are lots of liquids that can stain a slate floor. Cooking oil, candle oil, soaps, coloured liquids.
While they are unlikely to soak through the slate, they can penetrate into the surface of the slate, leaving spots and marks. A stone sealer will help prevent the spill staining your slate.
2. The type of slate
Whilst the slate used on roof tiles has little porosity, slate can vary considerably in its porosity.
The highest quality slate, e.g. welsh slate can have a wide variation in the water absorbtion. There are also plenty of types of slate that are quite absorbent, e.g. Indian slate.
So to make sure you should always seal your slate floor.
Now you have to decide what type of sealer to use on your slate floor.
We offer 3 types of slate sealer, impregnating, Hybrid or Topical Surface Sealers.
Our tests have confirmed that our CeeTech Hybrid sealer outperforms any other sealer we have compared it against. The main reason is that CeeTech is a hybrid impregnating and film forming sealer. Also the product is a urethane sealer, which is much more hard wearing and longer lasting than impregnating or Surface sealers. However, the produce it significantly more costly to source and to apply. So we still offer these traditional sealing systems.

A topical or surface stone sealer sits on the surface of the stone, giving the slate tiles a slight sheen or high gloss. They are usually made from a blend of polymers called acrylics.
Many of these acrylic topical sealers are tough enough to act as a wear layer on the stone. Many people prefer a surface sealer on
A surface sealer on rough-surface or riven slate tiles will be easier to clean with a surface sealer.
Once your slate floor has been sealed, it is a simple job to maintain it.
First dry sweep to remove dust and grit. Then just clean it using a micro fibre flat mop and a mild solution of stone cleaner.
It is important to use a stone cleaner because standard household cleaners can damage a stone sealer.
Natural wax gives a stunning finish to a rough or riven slate floor. When the wax is laid onto a floor that has initially been sealed with an impregnating sealer, you have a beautiful, easy to maintain, long-lasting finish.
Wax is not necessarily harder-wearing than a modern acrylic surface sealer, but it does give a more natural sheen or polish to the stone
Wherever possible, we suggest finishing a slate floor with a natural wax. However, our recommendation will always be based on assessing your situation.
The right care and maintenance will keep it looking beautiful for years to come. Sealing your tiles may not be necessary, but you will only find out if you never spill anything on them. And then it may be too late. So it’s a safer bet to seal your slate floor with an appropriate stone sealer.
