Hey all.  So I have a question about laying vinyl over existing vinyl in a home.

Background - I rent and have a really good relationship with the landlord - he has just done the insulation and is about to replace the kitchen bench, sink and taps, and he lets me paint the house how I like.  So a win-win for us both.  However the floors are really old and the vinyl is splitting in places and the joins are coming away.  We have discussed replacing it, but to do it properly would involve replacing the sub-floor, which is very not flat.  This would be in the bathroom / toilet, the kitchen and the dining area.  So we would have to move out.

So, back the original question.  I thought about laying new vinyl over the existing, for 2 reasons - aesthetics and hygiene (its hard to keep clean when the seems are splitting).

Is this possible?  I have done a floor replacement before in my own house, I bought heavy duty stuff that simply stayed in place due to its weight, but it wasn't cheap.  Are there other options?

Many thanks all!
