Re: New Shackster needs a Painted Screen!

I should reiterate wbassett's first recommendation. Do as MM has advised you. Apply the two thicker coats with a roller and sand the surface smooth with a wet sanding sponge. That should remove any trace of roller texture. The two thick coats are to provide enough thickness for you to sand without going through the SF.

A sprayed top coat of SF should then be very smooth and have not texture. As wbassett suggested , let it cure for a week or so. Then if you are not happy you could consider alternatives.

I did roll the two thick coats as suggested. Although I have not tried to sand it yet, I cannot imagine that any amount of wet sanding is going to correct the amount of texture I currently see when I fire up the projector. Then there is the issue of supply -- after 6 sprayed coats of SF and 2 "thickly" rolled coats it is just about gone. Possibly enough for a thinly sprayed final coat but again, I just do not have much hope for the SF screen. Even after these steps plus time for curing. However, I am going to follow the recommendations to completion before going in another direction.

Dumb question....is wet sanding simply soaking something like this (below) in water? I have a few of these in medium grade. Does wet sanding accomplish that much more than dry sanding? I have used these on the wall (following Kilz2 coats) and it just doesn't seem like they would do anything to get rid of my texture.

Re: New Shackster needs a Painted Screen!

Wet sanding keeps the grit clean and helps paint from building up. When that happens you're no longer sanding where it's all clogged so you're not getting even sweeps.

Is it a dual 3M sanding block? I use the coarser side to knock the large areas down and then the fine side to smooth everything out.

If this doesn't eliminate it and you still have too much texture, I personally would go to liner paper and put a very thin skim coating of drywall mud along the seam between the two sheets of liner paper. You'll get an very smooth finish this way and once primed you're set to apply any paint application you want.

To answer your question - yes. You would soak it in a bucket of water. Keep the bucket around as you should dip it in and rinse it out occasionally. We definitely need to see a shot of this texture. It is drywall isn't it?
Yep, drywall with what I always considered a normal/medium texture. Here is a shot that I took from up close approx 2 feet away before I started the project. This is unedited except for a slight boost to brightness since lighting was not good.

A little extra work but this sounds like a good approach for whatever screen application I end up going with (as you said). So I've been reading up on liner paper and found some of your old posts on the old forum with good information. Is wallpaper paste the recommended way to get it on the wall? Then I would skim some drywall compound over the seams, sand and put a few layers of primer down? If the paper comes in rolls that are 26" wide I would need three rolls for my approx 62" tall screen.

How thick is the paper? Does the texture not come through the paper at all?

12th,

Apparently your google image thing didn't work. I downloaded it, saved it and re-uploaded to my photobucket account. I edited it in your post from there. You may want to try photobucket or webshots or something similar. I couldn't tell you why the google link doesn't work but it didn't.

That does not seem like much texture to me. Anyone else? Is that the SF on it now?

mech
I have PhotoBucket and will use that going forward. That is just my builder beige wall before I touched it with anything. Again, the photo is a little dark but I did not give any thought to lighting, camera settings or editing because, quite frankly, I didn't think I would be analyzing this particular photo 2 weeks after the project started.

Re: New Shackster needs a Painted Screen!

Next time you photograph texture, place something in the image for size reference. I find a pencil works well. It is difficult for me to judge the texture from that photo because I have no idea how much area is shown.

One more thing before I go . Wilsonart laminates have that much texture on them. I can't see how that'd be that big of a deal. But let's wait for the painters to chime in first.

Doesn't look bad to me either. But, if this particular paint application doesn't work, it'll be blamed on 12th Man because

"he ain't got a skreen as smoooth as a baby butt like he's s'posed to...how can he 'spect the light to fuze when his skreen looks like the fargin' Rocky Mountins?"
[/IMPERSONATION]

In all seriousness...from what I've read, that mix is tough to work with (I believe I've read somewhere that it's a b*tch to work with) and very sensitive to doing one of MANY things wrong. So much metallic...oh the shiny, metal woes.

I'm pulling for you 12th Man...hope you get it worked out. It sucks to put this much effort into something and have it not turn out the way you want it to. Like others have said, maybe it'll be OK if you finish the application and let it cure???

Re: New Shackster needs a Painted Screen!

Here are a few shots on the SF screen. Apologies for the bad photography but the sun was going down and I tend to think the pics make it look worse than it does in person. Just wanted to give you guys a better point of reference.

Re: New Shackster needs a Painted Screen!

There seems to be a lot of surface sheen. It is that surface sheen that will make the textured surface more visible.

What were the ingredients and quantities?
