Why again mold on the joints? Agonizing replacing sealant

Once sheathed in the familiar walls of the bathroom plastic. Now here's the second time in 2 years asking to replace the sealant at the junction of the pallet and the walls. The first time was a tape, she came off in six months, in the end everything zasilikonil. Sealant took normal brand-name, but a big name, apparently, "does not cure." Done on the conscience, with degreasing, so hardly I tore it and then not completely.

This is the case when doing too good - too bad. Picking trowel, screwdriver, chisel, pliers even twitched - all to no avail, since the silicone layer goes down well with the rim. Nothing worked properly remove until Construction took a knife and cut through neat silicone on both sides for all its depth.

An hour after the start of the cut silicone band still managed to extract. Below it is free from mold, and generally under the pan is dry, so the reason for its occurrence had to be sought above. Before applying a new layer of sealant carefully poprotiral tray and the wall at the joints solution of bleach and given time to dry.

Since the probability of the formation of mildew remains, a new layer is deposited on top of the two pass without pausingbut without fanaticism, so that in case of replacement did not have it again so long to tear off. Decided to look further, what about the bars in vents? And so...

It seems that part of the reason is unclear, and it can and basic. Net, as can be seen, packed well, it does not give moisture to leave the cabin, but the "flowers" and bloom. Here neither a silicone does not help if the normal ventilation is not provided. And the stall door should always be kept open. After cleaning the air grid began to go noticeably better.

The result after re-sealing so turned - 6 photos. I asked the hostess to once a week rubbing butt bleach and monitor his condition. I can only add that any silicone at a constant humidity, even the best health, for $ 10-15, over time, mold eatsEspecially on plastics. So, timely cleaning of ventilation grilles - the first case.
