Marmoleum Floor Restoration St Andrews

When would we recommend restoring a marmoleum floor and only apply a sacrificial dressing rather than the more permanent solution, of a polyethylene wear layer by Dr Schutz?
This property is a case in point, 9 out of 10 times we would recommend cleaning the floors then apply a clear polyethylene wear layer to the floors (usually with a satin sheen, however mat and gloss are available).
This property will be up for sale in the next week and the owner wanted to revitalise the floors knowing that we would be applying a sacrificial dressing which would give the desired result in the short to medium term requiring periodic maintenance.

Our client was astounded at the results 
She said “ The floor looked amazing, I don’t know how you did it but they look brand new “
