Bottled Ship Builder

Recommended Posts

So ive just seen the sib i made for my dad back in may and much to my dismay discovered mould growing all over the ship, im thinking that maybe it was corked to quickly and still had too much moisture content, as this was built in very very short notice. 

So now i have brought it home to try and carry out emergency mould removal, hopefully i can cure it before its irreparable! 

So was wondering before i make a huge mistake, does anyone have any advice as to what to use to remove the mould without damaging the acrylic paint! Thanks. 😁

The black marks on the hull and the furry growth on mizzen and foremast, also the whale tail are most affected.

My experience with acrylic paints once they have dried is that they are very resistant to solvents, even acrylic paint thinners. I'd try a touch of cleaning agent such as that used for baby's bottles or the steriliser/cleaner used in home brew, which are designed not to damage the things they are cleaning, on an area on the 'off side' of the SIB first and see what happens. If that works OK, then move on to the rest.  I'd also give it a couple of hours in the sunlight afterwards - nothing like UV rays to kill fungal spores etc. This may also dry out any remaining moisture. I have heard of using an aquarium air pump to force air in to the bottle for a while to dry things out. Wish you luck.

Ive just tried a fungal/mould cleaner and it seems so far so good, i have also got an aquarium air pump set up and some packets of silica gel inside, so now its a waiting game! Will put it out in the sun later if it decides to come out today! Its been rather wet of late here in essex😢. Thanks for the great advice, i was very nervous as of what to do as its a first time for me and hopefully a last. I will update later, thanks exwafoo. 😊15988655102197385361381028200251.thumb.jpg.1e4dd8e5e896572aad803530f57403e4.jpg

You are welcome. Hope it all goes OK. Many, many moons ago, in the days of my youth in the Fleet Air Arm, one of the routine servicing operations on aircraft radios was to replace the desiccant crystals in the aircraft radios. The forced air cooling was blown through these to keep the inside of the radio dry. They were blue and turned pink when 'wet'.  They could be dried out in an oven and used again if need be. Later designs had single use disposable (more money to the radio manufacturer) desiccant cartridges with an indicator paper. I've looked on line, but can't find the reusable ones (they were poisonous), but they would be very useful in cases like this.
