Does drying time apply to fresh cedar? Prime first?


Building new stairs up to a porch, posts are cedar but remainder is PT lumber. I know the PT needs to "dry out" before I can paint it but does the same apply to cedar? Prime now, paint later? Both now? Both later? Thanks!

no prime or paint immediately,actually back priming and priming all cuts is a good idea too

Can you clarify this for me a bit? I am not familiar with the term "back priming", and by cuts I assume you mean all end grain?

Thanks for your help!

back priming means just that applying a finish to the backside of the cedar
and ALL cuts should be primed before installation,you can get cedar pre primed

the most common reason for finish failure on cedar is letting the sun degrade the fibers and lignins on the surface of the wood,this can happen in as little as 2 weeks

i like to prime all sides and have 1 coat of finish on the wood before i install it,then 1 more coat of finish after installation

does that apply to fresh/wet PT wood? Or are you speaking just to cedar?

any type of wood for outside use should be protected imo

as far as the pt being wet,i would treat any cuts with at least a clear water repellent

a neat trick to try and figure out if pt is dry enough to take a finish is to sprinkle a few drops of water on it,if it readily absorbs it within 15 min its ready

Any type of wood should be dried out before applying a coating. If you coat the wood and it contains to much moisture you will have coating failure issues, you really should use a moisture meter first to determine the moisture content, usually for most coatings a moisture content of 15% or less is suitable to apply your coating.

very true house painting guy,but how it dries is more important,exposing unprotected wood to uv can damage the very wood fibers your trying to protect
