Rustoleum hammered recoat time

[Rich P]

The label says recoat within 4 hours or after 7 (yes seven) days! This is on the quart size. The rattle can version says recoat within 1 hour or after 48 hours. I can just barely go along with the 48 hours but 7 days seems excessive to me.

Does anyone have any idea why they are calling for a 7 day drying period?

(Northern California is warm and dry right now so like I'm battling low temperatures and high humidity.)

My guess is that the solvents and solids skin over after the recommended 4 hour time and won't allow good adhesion after that happens. The 7 days seems excessive to me, too, but is probably overkill to allow complete curing under borderline conditions.

During the first four hours, the 2nd coat will "burn into" the first coat.

After four hours (but not waiting seven days), that first coat won't have cured and you'll be covering it with a barrier (the 2nd coat) that will prevent the 1st coat from properly curing.

If you've already missed your window, just suck it up and wait. Yeah, you could probably get away with four or five days, but safer to wait the seven.

I've found that the key with spray paint is several thin coats applied just a few minutes apart. It tacks pretty quickly. I can get four to seven coats on in pretty short order, and then I wait the full seven days for the final cure.

I'm going to place the already painted parts in full sun for the next day and then poke at the finish to see how soft it is. I sprayed the quart size product, thinned a bit with xylol as per their recommendation. Went on thinner than I expect the manufacturer would have wanted. This is Tuesday so I'll report back on Friday or Saturday on how things went.

Sounds like a call to the manufacturer may be in order. While many coatings won't dry fully for 30 days or more, 7 days for a recoat seems excessive.

Called the Customer Service number. The good news is the wait time was very short. The bad news is I got the "party line" on recoat. When I asked if there was a difference in the formulation between the quart and the rattle can, I didn't get an answer, other than that if I didn't wait it would cause the second to "wrinkle". I figure it's a CYA "worst case" position.

Since their two first application techniques for the quart are brush and roll, these would probably result in a thicker first coat with longer recoat times.

Guess I just have to figure out where I put my "patience pills" and take a handful.

I have used rustoleum paint in the past and neglected to abide by the recoat window.
The second coat did indeed wrinkle the first coat. It needs to cure completely before the second application...or you need to get the 2nd coat on quickly...like the directions say.

Pecker, what did you do after it wrinkled to correct it? Sand it and then paint again?

I neglected the warning and it doesn't look too bad but the hammered finish is definitely nice in some areas. Oops. My problem is that I let it dry over night and applied the second coat the next day (outside the window mentioned). Now I have a few patches on the table top that look somewhat flat and glossy where the rest looks textured. So now what? Do I sand the glossy areas or the entire thing before or after the 7 days and try again, this time with a roller and not a brush? Suggestions?

I have done the same as you and then tried most every thing I could think of to fix the problem. Non worked but to sand it down through the paint to whatever is underneath. I then started over and followed directions for a good result. I would wait the 7 or so days to sand. I started early and had the paper load up very fast with uncured paint, by the next weekend it sanded like it should and went down to bare metal very fast. Used Rustoleum primer and the hammered paint again, this time doing it fast on a warm day. I waited till the next weekend to use the table, perhaps not necessary but after screwing it up once I didn't want to take a chance.

good luck

Thanks Bill.

I unfortunately I had painted outside the window as I mentioned and I'm letting it sit hoping it does cure given time. I had put a light weight item on the table over night despite it being painted last on Thursday and today being Monday and well it left an impression. I wonder if the coat underneath will dry or if I have to strip it and go again.
