It took a good 3 hours of sanding and checking the level using 50 grit paper to get it as close to flat as I can. I'm still filling in the hollow above it.


Whatever is working for you! Glad you found a way to identify highs and lows across a large area.

I am reminded a public school teacher who posed to us the question: "If you take a number and divide it in half, do you ever get to 0."

I am also reminded of my kids favourite traveling phrase: "Are we there yet?"

Sigh.

I feel your pain. I put almost 100 hours in block sanding a '78 El Camino, though most of it was a steep learning curve for how much NOT to sand off before needing to reprime and (almost) start over. But the end result was worth it.

Lets hope I don't hit that 100 hour mark, but you are exactly right about learning what not to do.

At least I'm making progress. 70% of the screen is where I want it to be. Its that last bit of leveling out that seems to take the most effort.

Speaking of El Caminos, I saw on on a trailer on the way back from Wine tasting yesterday. It looked to be in really good shape, though I had no way of knowing if it was rebuilt or original.

As a further side note, you know you're getting old when the inbred bastard child of the automotive world of your youth becomes a classic.

Yes, I'm waiting for plaster to dry. Again.

So, while I'm waiting, here's how I would approach my wall now:

1. Use a level or other long straight object to mark all the high and low spots relative to each other. Whats high in one direction may not be in another. Its a three dimensional puzzle and there may be a whole section of wall to be sanded down to get close to level quickly.

2. Take down the extreme high spots as much as possible using the roughest grit paper possible. A grinder would be tempting, but probably not controllable. smile

3. Sand and TSP the screen area to prep for plaster adhesion.

4. Do the level exercise again and work on any high spots I can with 50 or 80 grit paper.

5. fill in the extreme low spots with a dryer than normal mix of mud (so you don't have to wait forever for the damned stuff to dry). For the really deep dips, it might actually be better to use a compound designed for plaster and lath walls that is meant to be put on in thick coats.

6. Measure, sand and fill where needed again.

7. NOW start the skim coat process.

I suspect that the first six steps could be done in a two days. From there, skim coating would be a far simpler process.

Things you can do with a laser level, while waiting for plaster to dry, to be really, really obsessive and drive yourself crazy...

This idea came to me while falling asleep last night.

My whole wall is out of level by 4mm from the top to the bottom of the screen. Its surprisingly uniform over the length of the screen.

I've found whole new low areas with the laser level with a little fiddling. They are only about 1mm low, but if you want to be really obsessive...

I just love to get my money's worth out of the toys tools I buy. grin

Chipity, chip, chip...

Hmm, I've got quite the ledge going on at the top left of the screen.

Still glad that you are just "painting" your screen or do you wish that you went with a regular screen? Cost wise I have about $350 (probably less) in my 138" Seymour AT screen. $250 of that was the screen material, which of course a non-AT screen would be a lot cheaper, and the other $100 was wood for the frame, brackets, staples, some paint for the frame... My frame was assembled in about 4 hours from start of the first cut of wood, to being hung on the wall.

Just wondering where the painted screen falls for price and effort?
