Sealant application

I'm worried that I have put too much sealer on my slate tiles.

The bottle says that it covers 10m2, which would be 100sqm My room is 13sqm which is 3.3mx4m.

Can you please let me know how much a 1 litre bottle of colour intensifier and stain block is meant to cover?

Is it 10m2 which is 100sqm?

Or is it 10sqm which would be eg 2mx5m?

Thank you Jillian

One litre of sealant is sufficient to cover an area of 10-13 m2 twice.

We recommend one coat prior to grouting & one further coat after grouting your new slate.
