Exterior sealant for wood ?

[gingerneil]

I am about done building a new shed/playhouse. Its clad using shiplap, with 19x38mm strips on the corners that the shiplap butts up to in order to cover up the sawn ends. I am looking into whether or not to run sealant down the edge of theese strips to seal the cladding, and also down the sides of the sawn edges before I secure the strips - any thoughts ? If it a reasonable idea, can anyone please recommend a good exterior sealant that will adhere well to wood.

Cheers.

It is prudent, end grain of course sooks in liquids, so you might want to apply a couple of times prior to fitting the 19 x 34 end covers...pinenot

Thanks. So..... treat the end grain, then a few beads of sealant followed by the trim and then more seal?
Any tips on type of seal?

You've got the procedure, as for the seal there are many to chose from, so just go for the colour that takes your fancy...pinenot

Ok, ta. I'll pick up some brown Dow corning from screwfix - looks just the job.
