Dr Bob Posted September 24, 2019 Report Share Posted September 24, 2019 I've also got piccies of penduline, marsh, willow, bearded and blue tits. The only one I am missing is the crested one but the only live in the frozen north so I'm not going up there. Link to comment Share on other sites More sharing options...

Hudds Lad Posted September 24, 2019 Report Share Posted September 24, 2019 you wont see too many Coal Tits soon, they’re all being replaced with Nuclear, Biomass & Solar Tits (Renewablidae to give them their latin family name) 3 Link to comment Share on other sites More sharing options...

We had our bote repainted last winter as the coal bags on the roof had wrinkled the paint. An air gap is the best thing. Link to comment Share on other sites More sharing options...

Flibbertigibbet Posted September 28, 2019 Author Report Share Posted September 28, 2019 Many thanks for all the responses. I am aware of the problems caused by damp, but this appears to be something much more vicious, as the bags have only been up there a matter of days, and it does look like spots of paint stripper have been dripped on the roof. I took a picture, I hope it appears here. The top coat was wrinkled and softened, it just rubbed off when touched. It's dried flaky now. Bit annoying as I touched up all the rough bits of the roof last year. Lucky I still have some paint left! Link to comment Share on other sites More sharing options...
blackrose Posted September 29, 2019 Report Share Posted September 29, 2019 (edited) The plastic sack is relatively inert compared to the coal inside the bags. When I was helping to restore a couple of 1890s steam boats on the Thames we had to pull out the coal bunkers to de-rust and epoxy the bilges underneath. The corrosive action of the coal that had fallen down the sides of the bunkers and ended up in the bilges was very clear to see compared to other parts of the bilges. Coal sacks are only thin and contrary to popular belief thin plastics aren't waterproof and do allow water to slowly permeate through. So in addition to direct exposure to water running in and out of those small holes you get in the sacks which has picked up coal dust, I suspect that there's some permeation through the bags of whatever the acidic and corrosive chemical solution that's created inside them when the coal gets wet. This is all in addition to the trapped moisture effect on the paint as described in other posts. I use these rubber mats with dimples underneath, which at least reduces the contact surface area and allows the water to run underneath rather than sitting there trapped.

blackrose Posted September 29, 2019 Report Share Posted September 29, 2019 (edited) The other thing to bear in mind is that unless one is extremely careful, chucking 25kg sacks full of rocks onto paintwork may have some mechanical impact or abrasive effect!

You can get the same stuff in doormat sizes for about £6 or £7 on ebay and cable tie them together but I doubt it works out any cheaper. Wilko also do a thinner doormat version for about £4 but the quality isn't as good. Edited September 29, 2019 by blackrose Link to comment Share on other sites More sharing options...
Richard10002 Posted September 29, 2019 Report Share Posted September 29, 2019 My boat had these types of mat on the cruiser stern when I bought it. Despite looking like the will avoid water collecting, they didnt work and, once removed, we found a pretty rusty old deck underneath. So I wouldn't rely on them on the roof with coal sacks, unless I was disciplined enough to remove it all every few weeks and give it a good wash and rinse.

Put rubber mats in thinking it would let water flow out from under kit stored and am now having rust problems. Do not know what the answer is.

Chewbacka Posted September 29, 2019 Report Share Posted September 29, 2019 Those mats tend to conform to the roof and hold water in each ‘well’. You would be better off with slats to let the air in. You could use an old pallet, though you may think that might detract from the beauty of your boat. Link to comment Share on other sites More sharing options...
