How do I know if my slate floor is sealed already
Asked by... Andrew Newton from Liverpool

The Question

Hi, I have just moved into a new house and it has an old slate floor. How will I be able to tell if this slate floor is sealed
 

The Answer

Hello Andrew

You can very easily test natural stone surfaces for the presence of an effective sealer by following these 4 simple steps

1. Fill an egg cup with water
2. Pour this on to your slate floor
3. If it beads in to droplets like it would running down a glass window then there is sufficient sealer present.
4. Should the water spread and soak in after 10 mins, it is time to reapply your sealer.

It's always a good idea to clean over the slate tiles with LTP Grimex to remove old sealer/wax layers, clean with water, let dry and reapply your chosen sealer.

Your natural stone surface will look as good as new!
