Using a Slate Sealer

Posted by Base Coatings on 10th Sep 2021

The natural beauty of slate makes it a popular choice for flooring applications both indoors and out. Slate is a very durable natural stone that is not only pleasing to the eye, but also has a great feel to touch and unique texture.

However, like all natural stone, Slate needs care and attention in order to maintain its good looks and protect it from stains. With a little bit of effort, care and maintenance, a slate tile floor can last for decades.

Slate is a foliated metamorphic rock derived from shale and consists mainly of grains of mica and quartz. While most slate is grey to black, the rock may also be red or purple, depending on its mineral content. The surface of slate is generally uneven with cleft planes which can spall or flake due to the cleaving of the stone along its layers.

Like most other natural stones, slate tile flooring requires sealing to protect it from moisture, spills and prevent staining.

A simple test you can perform to see if your slate tile needs sealing is to pour a small amount of water on the surface and leave it for a few minutes. Then, wipe away the water and see if there is a darker mark on the surface where the water was sitting. This will indicate that some of the moisture has penetrated into the slate, which means it would be a good idea to apply a sealer. 

Sealing your slate will protect it from stains by creating a barrier that prevents liquids from soaking into the stone.

The Base Coatings Slate Sealer 321 has been designed to enhance and protect slate and natural hard stone surfaces, making it an excellent choice for sealing slate.

Once applied, Slate Sealer 321 will give a beautiful high gloss, wet look, clear finish and provide a smooth washable surface which protects the slate from stains, spills and reduces the ability of moulds, algae and lichen to discolour the surface. 

Slate Sealer 321 is a UV stable solution acrylic with excellent optical clarity and is designed to provide many years of service for both indoor and outdoor natural stone surfaces.

Base Coatings 321 Slate Sealer is well suited to protecting new surfaces or restoring aged and faded surfaces. It provides a high gloss finish while enhancing the natural colours in the slate and seals porous grouts to resist staining.
