hi there fella, my wooden garage is badly leaking and damp but im planing on spraying my bike with used engine oil for the winter months inorder to give it a bit of protection. works really well on the underside of cars. i'll have to make sure that the oil wont react to any rubber on the bike before i do though. all the best fella, chicago

Mine is also concrete base, pre cast concrete walls and asbestos roof. Wooden up and over door. I don't use it for the car and try not to park bikes in there when they are wet. I have a heater on most weekends when I'm out there in Winter. On the bikes I always keep the bright work wiped over with WD40.

The garage can be damp but mostly keeps the wet out, though you do get a rather splendid effect when it snows as that can flurry in through the ends of the corrugations on the roof.

you can get filler that is shaped to fit, might take a bit of digging around to find but it does exist

Aldi often sell large de-humidifiers ( the plastic box type with a bag type refill ), they also often sell the refills at a good price.
I have a few of these in various sheds and it's amazing the amount of moisture they collect.

If any knowledgeable members would like to tell me what the resultant liquid is that they produce I would love to know, I've been pouring it on weeds but it doesn't seem do them any harm

hi guys, ventilation is the answer, if you have a roof space that you could install a D.V.S. your problems would be solved,
  D.V.S.:- direct ventilation system,cheers

Hi All,
At the risk of starting a DIY building thread  *eek* , heres my 2cents worth !!!
insulation, insulation, insulation *ex* *ex* *ex*
If you can afford it get rid of the corrugated sheeting and replace it with insulated cladding
Insulated up and over doors are available, draught proof the edges
line the walls with high density building insulation, then sheet with ply

The 8mtr x 4 mtr shed I built a couple of years ago, has a steel frame, walls and roof are insulated cladding
I got secondhand double glazed doors and windows
Its extremely comfortable summer and winter, a small heater for a few minutes on a winters morning, and its goood to go for the day

My concrete built "garage" has a felted and tiled roof, I use a dehumidifier there during the winter

I would not use old oil as a protective coating, it can contain nasty combustion acids  *eek*
WD or even better ACF 50 will protect the bikes a lot better

(maybe that was more than 2 cents worth?? )


Regards
John

asbestos is the problem, it sweats and when it freezes outside asbestos is bad , it holds the water inside then freezes and drops down when it thaws.
you can actually get a vinyl, tar and grit covered roofing same shape as corrugated which is better. alternatively wander around industrial estates, you can pick up old pallets, some big ones , will make good roof beams.

I'd guess that for any re-roofing project the big cost will be disposing of the asbestos.

And I actually like the snow flurry effect, like being in one of those little globes - just me and the bikes; all shook up.

hi , i have a concrete garage and floor, i laid down 1" x 1/2" lengths of wood ( it  matters not the size of wood) every 3-4 ft apart , drop some insulation in between poly or fibreglass, i got some cheap interlock floorboards from a timber merchant (you can even get reclaimed floorboards)  and screw them down the floor is never cold now and it helps stop condensation (i dont get any now) all done very cheaply, it only raises the floor by about 1 x 1/2 ", i  hope this helps   *smiley4*

I found that locking a hedgehog in there with an open bowl of used engine oil soon had pretty much everything coated in rust proofing. Little varmint.

They are basically much like fridges and can suffer from similar problems like icing up of the water pathways. I have one and it works fine when the weather is not too cold but won't work if the shed temperature drops below about 5 deg. c.

Hi all. I have one of those metal sheds from Argos, condensation first couple of years was dreadful, the colder the weather the more icicles would be hanging from the roof, thousands of them. I have a timber floor so when they melted onto the floor the cycle started all over again, the answer insulation and i think most important ventilation around the bottom and top of the shed, the building has to breathe, problem solved.
