I need some help, advice...? Painted my OSB, and it's soooo sticky....?

Good evening,
I am having a very similar problem... I looked online for information on how to paint the floor in one of my spare bedrooms where we have the Cat Liter Box, and it is OSB Board. Your website said
that I needed to paint the OSB first with a Primer, and I did... It said to use a Acrylic latex stain blocking primer that will hide any stains on the OSB. This seals the paint and prevents any bleed-through, in which I did.
Then it said to use Apply a top coat of oil-based paint in the color of your choice and allow it to dry. Repeat the process. In the end, you will have a beautifully painted OSB wall, roof or floor that should last a long time.
I did all of this and my floor is soooooo sticky you cannot walk on it... what is the problem..? I used the Kiltz Primer, and it said that I could repaint it in 1 hour with another coat, and I did, and then I
waited until the next day, into the evening in fact to put the Oil based topcoat on it, and it is not drying...? It is sooooo very sticky...? Help....!

You neglected to say how long you've waited since painting it. Oil based paints can take a long time to dry, and that time can be delayed if the paint was put on too heavy.

I don't understand why the site would recommend a latex primer followed by an oil paint. That seems wrong to me, for a couple reasons... you don't usually apply oil over latex and secondly, latex primers aren't the best stain blockers in the first place.

Tell us how long it's been since you painted, and whether or not you stirred the can well (not just giving it a shake) before painting. IMO you just need to wait it out. It will eventually dry.

 

Thx for the response, it was in fact this site, here is the info

I painted the primer on 2 days ago, and the top coat yesterday, I didn't
think I used to much, about 1/3 of a gallon of top coat in a 10' x 10'
room...?
And yes, I brought the can straight home from Lowes and put it on,
they shook it up in their machine...
thank for your time and help

 

SWP states that it's ok to use their latex primer followed by an oil base top coat on either exterior or interior work .... but I've never totally bought into that especially for exterior or stain sealing jobs.

I suspect the biggest issue is the lack of air circulation in the room. Oil base enamels generally dry to the touch within 24 hrs and cure in 72 but low temps, high humidity and lack of air flow can slow down the drying process. Dark tints [or extra colorant added] tend to dry slower than lighter colors. I've run across a few times where the paint was defective and wouldn't dry properly but considering how many gallons of oil base paint I've applied over the last 40+ yrs - that's not likely to be the issue.
