Looking for equivalent concrete sealer

[OverflowIssues]

Looking to seal my concrete floor. I got recommended this based on the floor I have:

BMP366 (top left): https://www.dk-holdings.co.uk/pdf/flooring/index.html#p=36

They don't have the 5L in stock and I don't want to buy the 25L so I am looking for something equivalent that I can get from ScrewFix/B&Q/Amazon/Other online.

Description says this:
"Impregnates into concrete, pores are closed and surface hardened, reacts with Calcium particles to form insoluable Calcium Silicate. No dillution required, do not allow to pool".

Anyone know of anything equivalent?

Using a penetrating concrete sealer that works by reacting with the calcium in the concrete to form insoluble calcium silicate is a process often referred to as "densifying" the concrete.
