Preventing water penetration on sheets of chipboard

[signalnorth]

How do you seal up sheets of Chipboard in order to prevent water / dampness penetration?

I using chipboard as a baseboard for my model railway and although I'm very confident that the workroom it will be in is now dry I just wanted to take an extra precaution by sealing the chipboard.

What possible harm could come to it? Is your railway in the bathroom? I'm sure any water would do a lot more damage to your expensive train set than an £8 sheet of chipboard.

agreed, but suppose he spilt a glass of water on it, have you seen what some railway sets look like when finsihesd? (they are not my cup of tea, but the can look really good)

dont worry i had a layout in my dads loft for around 10 years through the extremes of cold and hot no probs except the dust

peco nickel silver track and jacson scale wheels if you can still get them

i still have part of the origional baseboard in my attic and its starting to suffer mind you its now 35 years old now

for a cheap and easy water resistant treatment, you can use water-based Fence stain (available in browns and dull green). It leaves a waxy finish so e.g. spills and splashes will not soak in and you can mop them up.

being a baseboard "john d" it will need to take paint glues for all the scenery houses and copious amounts of paper mache
so a waxy finnish may cause "leaves on the line "
