Slate Sealer

Slate Sealer can be applied to internal or external surfaces.

Yes, it will slightly deepen surface colour and create a satin sheen on slate which is in good condition.

Around 20m2 per litre. Please remember you will be applying 2 thin coats. As an idea we think you should be able to seal approximately 40m2 per 5 litre container. Please be aware some slates are more (or less) porous than others!

Yes, it is water based, low odour and dries quickly. Ideally apply with a flat microfibre mop or cloth making sure no pooling or puddling occurs. Apply a 2nd coat approximately 60-90 minutes later.

This product will deepen surface colours and leave a sheen. It does not produce a glossy finish or totally replicate the effect of wetting with water. Its purpose is to product a more natural subtle finish with a sheen. If your slate is in good condition and a darker grey/blue shade, or if its an Indian or Chinese slate this product will deepen its colour. Test before use to gauge the finish you will achieve.

It soaks into the surface with some product drying on the surface to produce a sheen. The sealer should be built-up in a minimum of 2 thin coats. Distribute evenly with a flat microfibre mop, cloth, roller or paint pad. The optimal finish is produced by applying this product in thin coats, do not allow the product to pool or puddle.

You can clean your floor with Floorseal Stone Floor Cleaner to remove general dirt, grime, wax, and certain old water-based sealers. You should use Floorseal Cement & Grout Haze Remover to remove cement-based grout hazes.

Always rinse the surface heavily with clean water after using any cleaning solution. Allow the floor to become totally dry before sealing.

It will capture some of that appearance, but be aware no sealer totally replicates the effect of wetting a natural stone with water. If the slate is in good condition this product will deepen the colour of the tile leaving a low sheen finish.

Yes, only apply this product to a totally dry floor. Do not apply to damp floors, you should never clean & seal a slate floor on the same day.

Apply in 2 thin coats 60-90 minutes apart. Do not apply in thick coats, it does not necessarily mean the stone will become a deeper colour or become super shiny! It usually leads to an overbuild of product and a sub-optimal finish. 3 thin coats are usually the maximum number of coats you will require.

This product is water-based so relatively low odour.

Usually within an hour – only walk on the surface with socks for the first 24 hours.

No, you cannot use this product in a wet room or shower cubicle. You would need to use an impregnating sealer such as Floorseal Premium Impregnating Sealer.
