paint over pressure treated wood

hello

a segment of my outdoor porch repair used pressure treated wood.
can this be painted over just like normal wood with an oil primer/latex top coat or is there something more involved?

thank you

 

What type of wood was being replaced? is the rest of the porch painted? or stained? is it decking? or something else?

Generally PT wood can be painted BUT it needs to dry out from the PT process first! Oil primer is top coated with latex normally works best..... but a solid stain might be a better option if it will go with the rest of the porch's finishes.

 

this is part of my "old wood porch" repair/repaint project. the porch is all regular wood but i needed to replace the wood base which one of the columns sits atop. i used 1.5" PT wood because it will be in direct contact with concrete. as per your prior recommendation i used Sherman Williams exterior oil primer with a duration latex top coat and am happy with the products. i would like to continue with the same products on the PT base if possible.

thanks

 

As long as the wood dries out from the PT process prior to applying the oil prime it will be fine. There are a few paints that say they shouldn't be used over PT but I think that it's mainly oil base floor enamels. The label will say if it shouldn't be applied over PT.

I remembered your previous thread ...... after I posted my first reply

 

i got the wood from home depot and it seems "normal" - meaning not noticeably damp or wet. so i will go ahead and try the oil primer?

BTW - thanks for your turn on to Sherman Williams, i like the products and ease of selection. its much easier for me to select the right product without having to sift through a dozen manufactures trying to make the best choice, the specialized advise and opinions dont hurt either.

 

Most PT wood sold is still wet from the PT process. If it was redried, you know it because of the increase in price. I know the big box stores tend to stock their lumber inside or under a shed and that helps the wood to dry but without inspecting the wood it's hard to say if it's dry enough for an oil primer. Dried PT wood will be lighter in weight [and possibly color] than it's wetter counterpart. If you oil prime the PT too soon - it will peel. Latex primer/paint gives a little more wiggle room but it's always better if the wood is dry before any coating is applied!
