Painting over outdoor 'treated Timber'?

I wish to paint over a new 'Treated' picket fence which the suppliers state '' Can be painted ''


Can you please advise me the best type of Undercoat to use for weather protection?


The top coat will be in a Gloss paint..


Thank you for any help.

Exterior grade oil primer.





Make sure the lumber is completely dry before painting. The treating process puts a significant amount of water in the wood, it can take a few months to dry out. Also, it is common for manufacturers to put a water repellent sealer on this type of product at the treating plant. If present, it needs to come off before you paint.





After priming with oil primer, you may paint after completely dry with an oil paint. If you are using a latex based paint, you will need to wait at least 2 days for the primer to dry completely. There is no problem with latex over an oil primer other than this and it is much easier to deal with.





Also, make sure you cover all surfaces of the fence when painting for best results. Don't forget the bottom edge of the pickets.Painting over outdoor 'treated Timber'?
do not use any latex based primers on pressure treated lumber. USE OIL BASED. With latex the material used to treat the lumber will bleed through and caused yellowing. Use a high quality oiled based product. I use oil based exterior KILZ...it is cheap and fast drying...1 hour. Then use an good quality oiled based paint as topcoat. Do this and you will be happy with the results with smiles and grins as wide and bright as a rainbow,
the new latex based exterior primers are excellent. If they stick to the fence like they do to my skin and hair then they should do the trick. Oil is always good, but I think that these days the latex based are just as good if not better. For the average do it yourselfer the latex is probably less irritating to use also. Good luck and may you never have to paint your fence again. Remember 2 coats of finish is always best. Take your time and use top grade products(that is brushes, rollers and paint) They may be a little expensive but will make your job go easier and last longer.
