Sheetrock Burned-house Already Painted


I need some advice. After the painter put the first coat on the walls, (eggshell-s/r finish is orange peel), I noticed that the s/r had been oversanded and they must have used a machine to sand the walls because every 8" or so, it is streaked. It looks like a wave pattern.
Should I have more texture sprayed over the paint to get a uniform look?
I know the s/r is burned because in places it is fluffy underneath the paint. Help!!!!!!!

Sounds like two separate problems.
*The burned/fuzz was not addressed before the primer was applied.
*Uneven prime coat.

Or 3rd problem, painter did not sand the primer prior to laying on the color. Primer causes the "hair" of the paper to stand up and if not hit with sanding mop between primer and color will leave even a perfect drywall job looking ill.

I prefer to address this problem before texture and priming.
No need to have a GC getting his panties in a bundle.

Re: Sheetrock Burned-house Already Painted


Thanks boycer88, yes, the sheetrocker burned the rock by sanding it too much. I haven't received any constructive answer yet, though. So am thinking of lightly sanding over the eggshell paint, then trying an area of flat paint to see if the wave pattern continues to show. Hopefully this will correct the problem. If it doesn't, I am going to try re-texturing with a heavier finish.

Re: Sheetrock Burned-house Already Painted


Sounds like the wave pattern might be from the sander using a Porter Cable power 'Wand Sander'...if I named it right. He used too much pressure and too heavy a grit or not used successively finer grit paper. Either way he f'ed it up.

Re: Sheetrock Burned-house Already Painted


I am hearing eggshell paint and texture in the same sentence. Is the wall painted or textured and then painted. If you have paper fuzz from over sanding I would suggest sanding down fuzz priming sanding again and painting FLAT before introducing eggshell

You've nailed it, Scipio. I will let you know how the painting over with a flat paint works.
thanks

Re: Sheetrock Burned-house Already Painted


flat paint won't work, I would skim the whole area to a level 5 finish, then lightly resand, then retexture. I have done it on commercial jobs where the drywall man messed up, and found that this is the best fix

Re: Sheetrock Burned-house Already Painted


Are these lines you said you are seeing, are they only where your joints are or are they all over? I jsut can't believe some bonehead textured over marks like that! Sounds more like inconstant prime coat.
If these marks are from a power sander then I'd be pissed.

Re: Sheetrock Burned-house Already Painted


After replacing the ceiling - tearing down the sheetrock and starting over - the same thing happened; still have that wave pattern. I now realize it's either the painter or uneven ceiling joists. If it is uneven ceiling joists, it is too late since I will not tear down the ceiling again. I am going with the painter Monday to watch him ROLL the ceiling twice, rather than spray it. I pray this will work. Or at least be presentable.
By the way, I had several walls in the house that were oversanded with a machine, I suspect, and one wall was really noticeable since it was in a room with 8 windows. So I had the sheetrocker do a skim coat, sand and retexture and now it is beautiful. If the ceiling rolling doesn't help, I may have to do this on the ceiling. This house I will be most happy to say goodbye to. Thanks for everyone's help.

Re: Sheetrock Burned-house Already Painted


I would bet my soul (And I don't even own it) that the painter is simply spraying & not back rolling. I see it all the time here & they always point to the finisher. Not to say the P.C sander Isn't leaving ridges, swirl marks, etc because they will sometimes. Make the painter roll the holy out of it!

Re: Sheetrock Burned-house Already Painted


And be sure to see to it that he SANDS in between the primer and next coat. All it takes is a light brush-down. It makes all the difference. That and back-rolling primer are the two biggest things that can make a terrific drywall job look $#itty. Is the painter on this job got time in and skills? These two factors are basic and the painter ought to know it.

spray on painters that think they can paint sure can make a drywaller look like crap. no backroll and everything photographs through.
