Presure Treated Wood And Staining????

Sellncars

New deck built last fall, hasn't been stained yet. My question is this, does the PT need to be completly sanded before the primer and stain can be put on?

Thanks,
Sellncars

you should clean and sand... no need to use primer with stain...

Just wondering...why should he sand it?

JMGP

sanding will get rid of the dead wood cells, splinters, ruff edges, mill glaze (if any), allow the stain to provide a smooth uniform finish...

Couldn't you get good results using a wood brightner instead?

Me, I would just clean it with Simple Green and use Penofin for PT on it and sit back and admire the results as I drank a Mohito.

A good brightener will clean the wood, help with any grey or green discoloration, and remove dead wood fibers with a light (800-1000 psi) power wash. I'd hit it with some timberbright pro wash it down lightly, let it dry, and stain it. I would skip the penofin and go straight to ready seal though.....many pros in the wood care sector consider penofin good food for mold because of the rosewood oil.

sanding would actually make it stain more blotchy.....

Cleaner and brightener
Usually no sanding

Yeah, I've 'heard' those rumors too, it always amazes me how many 'pros' base their businesses on rumours instead of facts they could discover by testing.

Anyways, it matters little to us in Colorado with humidity about -20% mold is not an issue out here no matter even if you were feeding it intravenously with an IV.

I have seen the results here in the south, and it's ugly....my experience isn't based on rumor. Many in the wood care field agree with what I stated probably because they've seen it too. Within a year or two around here penofin turns black and might as well be a petri dish.

Yes, I agree cleaner and brightener but...

"For new decks" I still sand just to remove some ruffness... not a deep sanding...just a light (quick) orbital sanding with 80 or 100...

sanding is not a bad thing to do... its just an extra detailed step..

never had any blotchy issues... and my customers appreciate the extra step...

Sometimes it needs it

I wouldn't believe any of that until I tested it for myself. Ran a control with Penofin, nothing and other brands and set them out and let time show me. What people think they are seeing and circumstances they know nothing about can be two different things. But that's just me, I've always been that way. I don't believe anything anybody tells me other than the manufacturers who spend lots of time and money producing white papers.

Hi Guys,

When i went to the paint store, they told me that i needed the primer and the stain. Both are Benjamin Moore, which i always thought was a good name in paint anyways. It appears that alot of you don't ever primer a new deck before staining? The primer has color in it the same as the stain. If this is true why was i told i needed a primer? Good sales pitch by a decent looking chic?

You don't primer stain
The only exclusion I can think of is you might want to hit nail heads with a dab of oil primer before solid staining (rust bleed through)
As I use oil solid stain that's not an issue with me

I would look into another type of stain. There shouldn't be a primer for stain......stain soaks into the wood and, well, stains it to the proper color. Unless this is a film forming stain....there wouldn't be any need for a primer, and if it's a film former, you don't want it because it WILL fail.
