Evening All, Hope all is well...I completed the grouting of my newly tiled bathroom wall at the weekend using Ardex FS - I heard this was avery good grout to use - and I have wondering if there's anything that the grout needs treating with afterwards before using the shower again. I've heard mixed stories about using special sealant or using a silicone based car wax on newly treated grout, but I just wondered what the experts think. I wouldn't want to to use anything that would discolour as the grout as it is brilliant white. Anyway thanks for taking the time to read Cheers
That looks like a good 'cement-based' grout - it sets chemically. I've never heard of the add-on finishes you've mentioned, and suspect the only thing it could do was discolour the grout slightly. I used a similar grout for my own tiles (I think it was a SF product) around 10 years ago, and it's still in very good condition. There are some areas of discolouration, but that's unavoidable in a shower that's used regularly. A good scrub - and sometimes the addition of bleach or similar - does the job on stubborn stains - but that was only needed after many years.
Ok guys, many thanks for taking the time to respond. I think I'll leave as is then. I assume all grouts discolour a little over time, especially that we live in a very hard water area, but I wouldn't want to exacerbate that by applying something that would prematurely discolour. Thanks again.
