    Great product. Did exactly what I wanted to the walk-in shower room.

  2. Tim Forster (verified owner)

    This is a great product. I wanted to use non-corrosive sealant for my kitchen floor grout. It didn’t change the colour of the grout and also hasn’t change the look of the tiles which in the past has been darkened by sealants. Follow the instructions as required.

    Works really well, recommend

  4. Sarah Fielding
