Hi,
I recently purchased a 1970s apartment and at some point during it’s life the original white bathroom tile has been resurfaced. That painted surface is now yellowed. In the shower there is mould visible beneath the resurfacing, as they also covered the grout.
The tiles are grouted to the walls with sand and cement without waterproofing behind, so I believe that this may have been done as a waterproofing measure at some point during it's life as a rental.
I am hoping to remove the old paint, remove the mould in the grout lines and re-seal the tile to ensure continued waterproofing of the wall within the shower.
I have purchased Bondall Waterbased Paint & Varnish Stripper, which worked ok on a tile test patch with two coats. I need to find a better scrubbing brush moving forward as it was a lot harder to get out of the grout.
I’m wondering if you have any further advice on what product would work best to re-seal the tile with a waterproof coating after this?
Thanks for your help and I look forward to hearing from you,
Nick
