The difference in bathtub refinishing from start to finish
The idea sounds good on paper but let us not forget we are refinishing materials like Factory porcelain, Fiberglass and cultured Marble Bathtubs. If you are using this fixture even 3 times a week those coatings will fail within 3 months in most cases.
When refinishing a Bathtub, Shower or Tile we must remember the old surface is a huge part of the new surface. For example if the old surface is fiberglass then you will know what I mean when I say it will flex and bend under pressure. It is very important to use a gelling agent so the synthetic porcelain does not dry brittle and chip away!
