If it is linoleum and not vinyl take care.
Linoleum can be damaged by exposure to high alkaline strippers and the pigments can discolour.

If it's Lino try hot neutral or mild alkaline cleaner and the pads previously suggested rather than slapping stripper all over. Rinse well before applying top coat. Floor sealer coats first and a buff before applying polish should be done to give an even base. It can be mega porous if it has no factory finish.
