Treating/Spraying Garden Fence?

[cambsno]

About 5 years ago I sprayed out garden fence with treatment - cant remember which one (either Cuprinol or the other make) which stains it a shade of colour and protects against weather. Thought about doing it again and planed to use a darker shade, any issues with that? Because it is supposed to repel water will the new one 'stick' or will i get a dodgy finish?

Can you buy a sample/small size first and try it on a section that isn't too noticeable?
There are normally 'helpline' numbers on the containers. The technical dept of the company should be able to tell you.

Afte 5 years, I would expect the old finish to be rather less efficient at repelling liquids than when first applied. If you can find out what solvent the new finish uses, try a little of that on an inconspicuous area to see if it beads up and runs off or is absorbed.

As an aside/add on, how do you "mask off" areas that you dont want the cuprinol on? Such as concrete posts and plinths etc. Cheers.

Have a look on the tin of anything you are thinking of using. They say what surfaces they can be used on.

Just had a look at a couple of tins in our shed. One says it can be used on previously treated timber that has been allowed to weather, the other(which is used for garden furniture rather than rough timber) says old paint or stain should be removed.

For masking off areas you could try a big bit of board held by a willing helper close to the post at about a right angle to the fence.

Newspaper stuffed into gaps and held there with wedges will mask concrete posts. We used to use old blankets to hold vegetation away from fences when I used to have to paint/stain/creosote panels some years go (helps keep any prickles out of hands too!) When it comes to walls at the end of the fence, we used to use a brush and cut in to the wall (carefully paint up to the line, not make a groove in the brickwork!)
