White speks on my painted fence.

Don't know what other people do, but I usually cut the picture, then paste into word then cut and paste into the message, seems to work, otherwise the picture is too big to upload.

 

Use photobucket or similar.

 

If they're new fences could be the green preservative pressure treated which is having an effect with the paint.

forgotten the term now tannalith?

 

Thanks Jit, that name I couldn't remember, need photo's to confirm, but the white specks I supect are saltings, sometimes you also get green specks, which I presume is copper salts, you get them on the surface of a boards,treated with Tannalith & Tannalith E, quite normal, can brush off, will disappear after some weathering of the boards.

 

Does it brush off, the way it's on the crossrail as vertical lines, don't look like salt deposits, they are usually random specks, this is on the surface of the brown finish, it hasn't come up from underneath the finish.

 

Was the tanalized timber newly treated or has it been around for a while as it is recommended the treated timber is left to weather for 6 months prior to any decorative finish being applied.

 

Maybe the neighbor got jealous of your new fencing, and splashed something silly on it

 

Come again?

 

That stuff looks expensive

 

Or didn't like the color.

B&Q have cuprionl x 2 2.5l tubs = £30

 

Very comparable price to other opaque wood finishes Jit such as Bedec Barn Paint, Sadolin Superdec, Dulux Opaque Wood Finish etc!

 

Application remarks:

Coating on fire protected cladding may cause salt precipitation/flaking.

Doesn't mention anything about using it on pressure treated timber. Maybe an undercoat should have been used.

 

This what you see with salting on pressure treated timber, can be just a few specks or sometimes a heavy covering.
