Yes I did to begin with. The bloke from Topps when he visited used it neat. I think I need the stronger option now. Must have left it too long to clean the first tiles. It was very hot and tiles at that end were in direct sunlight. Will explore the Lithofin option. Thanks for your advice.Might be a silly question, but did you dilute the first wash?
Anybody else reading this, you must dilute this product with water. Water activates this product.
I would recommend mixing first wash with water and use a spray bottle to keep the walls damp.
You can get these white pads from B&M £2.99 for 2:View attachment 109751
I would also recommend Lithofin Cement Away or Cement Residue Remover available from CTD in store but not online.
