Sealing a concrete floor

[gigz]

I’ve got a 6ft X4ft concrete floor in the lobby that i want to put those sticky back lino tiles on. Its just an area that i clean the dogs on when wet/dirty. I’ve put them down but odd ones keep lifting. Whats the best/easiest way to seal it or the best glue to use on them ?

I suspect there's dust on the floor that stopping the glue sticking. You could try an acrylic primer, or a brick stabiliser like SBR.
