For many there is nothing that can beat the richness and texture of natural products like; granite, limestone, slate or features crafted from terracotta.
Whether these are used for internal floor tiles, external paving and wall cladding, windowsills or decorative pots; as natural products, they need protection to prevent staining, abrasion and to repel water and dirt.
The new Osmo Stone and Terracotta 620 Oil for exterior surfaces will do just this.
The new clear, satin stone sealer has been formulated from natural plant oils and water repellent additives. It is benzine free and well within the EU VOC limits; making it healthy for you and the item you are applying it too.
Osmo 620 Oil doesn’t contain the hard wax like the Osmo Concrete 610 Oil. The product uses different types of binders which excel in an external environment, compared to the interior Concrete Oil, and is highly water repellent.
Can I use it on all types of natural stone?
Recommended use is for microporous natural stone, as the oil impregnates and penetrates the surface enhancing the colour, leaving a permanent wet effect. However, it can be applied to artificial stone in outdoor areas; but whatever the material, a trial application is always essential. Any concerns, just ask one of our technical team before buying!
How easy is it to apply?
If you have recently had new tiles laid, worktop fitted or garden slabs set down, ensure that they have seven days to ‘settle’, allowing all the moisture from the adhesives to be released.
The stone must have a completely dry surface and it is advised that any existing sealant or oils are removed first. It is also essential that the stone is frost-free.
The stone and terracotta sealer comes ready for use, so simply open the can, stir well and away you go!
Cover and protect any substrates that are sensitive to solvents – such as plastic and plexiglass. Then working in small areas at a time, ensure the product is applied thinly and consistently, avoiding any pooling or streaks. If you do get any excess build up, remove it with a lint free cloth.
When treating large areas e.g. slate flooring or limestone paving, it’s best to remove all the excess oil and polish with a buffing machine.
Drying time is 8-10 hours, but this will depend on ventilation to the area and/or item; then apply a second thin coat following the process as before.
Stone is a natural product so will not always react to treatments in the same way, hence why trial applications are essential.
However, after extensive testing by the Osmo technical team they have found that some very light-coloured stone may yellow slightly from the oil. For most this is barely noticeable and not an issue, but something to bear in mind. Always trial apply.
In addition, the slip resistance of the original surfaces may alter after the oil has been applied and cured.
When laying a new slate, limestone or terracotta floor, it is possible to seal the tiles prior to grouting to prevent grout staining. This is not always the case with dark coloured grout and could still slightly stain.
Osmo Stone and Terracotta Oil is an easy to use product, with a breathable finish – not prone to cracking, peeling, flaking or blistering; keeping your natural stone looking fresh and new for years to come.
