1. How do I clean up grouting that have black mould. Is there anything on the market please to do this or will I have to regrout. If so, please can you advise how to do this. I am a true amateur! Thank

2. Hi Girish I'll answer this for George, since he's away filming. To clarify, some tiles are porous - in other words, they'll absorb whatever hits them (whether water, tea, oil or grout - depending on where they are) unless they are sealed first with a tile sealant (sort of like a varnish, but for tiles). Once sealed, these tiles are then ready for tiling/grouting. If you don't seal them, they'll be left with marks that can't be removed. This applies to some natural, unsealed materials, not to ceramic tiles, for example. When you buy, you should ask then whether your tiles are sealed or not. Hope this helps!

3. Hello George, I am delighted to say that how helpful this site has been for someof the DIY work I am trying to carry out at home. I have never been that good with DIY but the guidance i got here to do jobs are very easy to understand and simple. However this is the first time I have come accross something that I don't quite understand in the tip and advice section, of how to grout Natrual stone tiles as it mentioned above and as it reads, "It's essential to seal some natural stone tiles before they are laid. Otherwise the grout and adhesive will be absorbed into the porous surface and is almost impossible to remove" I would appreciate it greatly if you can let me know what exactly means to seal the tiles before they are laid? Regards
