No problem at all

Agreed avoid the blue/brown bottle sold at ntuc, it has a bleaching agent inside, cannot be used on glossy tiles, will make them matt

Maybe i think is to protect the stone

Synthetic rubber better avoid, seems to degrade fast also

Makes the contractor give good customer service by slapping him

Should be just living room, i think from the way TS described

what tiles are yours? mosaic, marble or etc?

From what you describe it seems to be ingrained dirt and hard water stains. You can use something called HCL89. to clean the tiles I usually get it from http://hcl89.byethost10.com or http://hcl89.atwebpages.com One thing i like about it is that is creates like a protection like on the tiles so that it prevents such hard water stains or dirt from becoming an issue for your tiles Hope this helps you out

Silicone is already water resistant so how can mould attach to it?

It stands for Home Improvement Programme, short form HIP

Ah ookay now i know what he means

Very true indeed

Too much humidity always causes problems like spots on shower screens or etc

Then where is the timber part? You mean its at the side?

No, it will danage your tiles

By glazed, you mean matt or glossy?

Ya thinner does that, avoid thinner at all costs not worth it

Correct the NTUC one is nonsense, just a waste of time, pui

I burst out laughing at that

Agreed thinner makes things worse, this is from personal experience

Not necessary, could be due to high humidity also

Well too late for that now

You should of slapped your contractor when he sighed

I never trust china product too scary like nightmare
