Hi all. I have a 3 metre length of (B n Q) marley half round gutter with 2 end stops. I will be using it to treat 2.8m length door frame timbers. I have a solvent based preservative (cuprinol trade preserv.). The question is,will the solvent bugger up the rubber seals in the end stops?
If so, what type of sealant will be solvent resistant?
Thanks

Simple answer. None. Cuprinol is an acid based timber preserver and can eat its way through most petro-chemical materials with some ease.
Which is an interesting comment given that the sprayer that Cuprinol sell through B 'n Q for their Shed Preservative is no more than a standard garden insecticide sprayer.

And? If the sprayer is made from non-oil based material, then it's fine. Most sealants have a solvent that is oil based, and, as such, when they are exposed to a substance that enhances the softening of the sealant, even after initial curing by solvent evaporation, it will not be as resilient as it should be.
There is a difference between Thermo-Plastics and Oil Based Solvents.

some of the sprayable fence treatments though are water based not solvent
why not just line the gutter loosely with polythene sheet.
