‘Fixing’ wood stain under bunks

[dgadee]

When damp the brown wood stain on the plywood under the bunks marks sheets and covers. What can I do to fix this so that it becomes non soluble.

Varnish?

We fitted slats under ours which gives air space and has stopped all condensation damp.

Paint?

Yes, slats have been considered and may be investigated again.

Paint or varnish won't just lift? I suppose that was my concern.

Paint or varnish will stop your staining problem but will create a non breathable surface on which condensation will most likely form = damp mattress. Alternative to slats is the green stuff, like thick Scotch-brite pads.

Slats work best.
Easy to slide out of the way to access storage under the bunk.

You can seal stains with PVA but I don't know how durable that would be.

Thanks - think I will give the underbunk matting a go. Much easier to fit than slats and access to hatches seems possible. If it fails, then slats are option 2.

Fitted this to our forward berth in September last year to some effect. However the front 1/4 of the berth is painted GRP and there is still signs of wetness if it's been a cold night. However a lot better than it was without the webbing at all.
