We have decided to sell our old flat. However, before doing that I had to do something with the bath, which looked quite tired.
Post image shows how the bath looked like after some time of removing old layers off – you do not need to be this diligent, it works well over simply sanded surface. For fixing the bath I was using this cheap (22.22 USD) bath renewal solution Penosil Premium BathCoating.
Few days of applying two layers (each application takes ca 30 minutes) and leaving them to dry and voila. Bath looks really rejuvenated.
P.S. I can tell that this will hold for at least 2 years of heavy usage – sharp nailed dog wash 3 times a day, since this is my second encounter of bath fixing :)
