Shed problems :-(

[PeterUK]

I have been steadily doing up the shed over the last few months, fitting a few hours here and there after work (usually I'm down the shed around 2am to 4am). As it snowed heavily on Monday here I didnt go to work and managed to do quite a lot and only had to lay and glue the lino before I start building the racking.

I noticed there were a few dark patches that have appeared over the last few days on the back wall. I have just removed the 6 coats of paint with a 1600w heat gun and when I stripped out the mastic along the wall/ceiling edge there was a small but steady trickle of water. :mad:

There are now two oil filled radiators (3KW and 2KW) turned on to the maximum to try and dry any damp wood before repainting and sealing.

The leaking wall is the back wall and I will have to completely remove the 18ft of back fencing before I can get anywhere near treating and or repairing it.
I do NOT care about what it looks like once treated as this is something that can only be done once and I dont want to remove the complete back fence every year or two to re-treat it.

Is there a product that can TOTALLY waterprood/seal a tongue and groove wooden shed wall ?

I am thinking of using one of these products and treating the entire outside of the shed (walls and roof, even though the roofing felt is only a few months old and has 3 layers) apart from the front as it faces the house (and the old dragon will start moaning )

I'll chime in for ya... Like you said if you are not worried about asthetics I don't see a problem with the product. Just be sure to double check that the product will adhere to whatever the wood has previously been treated/painted with.

Yes, there are quite a few products. I, personally, am not familiar with them, but my wife actually works for a company that makes these products. There are different ways to go and different aesthetics that can be acheived, depending on what you like and how much you're willing to spend. Most better systems involve the application of a wet applied waterproofing, a membrane, and another wet applied waterproofing. Over these, a number of things can be laid, tile, roofing sands (in conjuction with the last wet application, or a new adhering wet application), etc. Your local contractors who do mostly commercial work should be familiar with the better products and choices available in your area. Some products are not available nationwide.

Oops, just noticed you're in the UK... don't know what's available there. The company my wife works for is worldwide, but many are not.

Problem solved :D

I bought 8.5 litres of liquid rubber and sploshed it over the offending back wall; and roof, it has been raining here like Noah was coming back to build another ark:p
Not a drop of water has come through :D:D

Best way to dry something fast is with fans if you ever have this problem again.
