Drywall finish examples.

Hey guys. I'm new here.
I have a question to drywallers.
I just start doing drywalls and I read a lot of information about finish level for drywall but I can't find any photos as examples for drywall finishing level. Main thing is what I'm interested in screws seams under side light. I understand that under level 5(skim coat) nothing should be visible. But what about level 2,3,4.
Sorry lads, English is not my first language, so if you didn't understand something from what I said, just let me know, I will try to explain better.
Thanks

Drywall Finishing Levels
Level 0: Level 0 implies that no finishing of any type has been done. At this level, drywall is simply fastened to the walls or ceiling.

Level 1: This level means that drywall joint tape has been embedded in joint compound, but nothing further has been done.

Level 2: This next level means that you have skimmed a thin coat of joint compound over the tape and covered the drywall screw holes. You can stop at this level if you intend to cover the wall surface with tile.

Level 3: At this stage, finishers apply a coat of joint compound to the tape and screws. Walls that will receive a heavy texture, such as knockdown texture, can end at this level. It would be pointless to progress beyond this level since texturing will produce a finish that is rougher than level 3.

Level 4: This is the classic drywall finish. Here, you apply another coat of joint compound to the tape and screws and sand the dried compound. This is the level that typically is used when a wall surface will be painted or covered with wallpaper.

Level 5: This highest possible level of drywall finishing involves applying a skim coat, if applicable.

 

My friend, I know what theory myself, I wanna see examples(photos) of that work under shallow angel light.

 

Sorry, but I don't think you will find that here. Sounds like you need an illustrated book on drywall.

 

Well it's too sad that no meisters can show example of their work. Thanks anyway

 

I don't know how well the difference between a level 4 and 5 would show up in pics anyway. Defects exist in a level 4 finish but should be hard to spot. It's pretty much the industry standard for residential construction. Level 5 is pretty much only done on high end homes ..... and not all of them.

I thought post #2 was a good explanation.

 

I think the problem is the inability of a photo to illustrate the difference. You would need to have two otherwise identical walls with identical light and perfect exposure and even then the difference will be subjective. Since you are new to the trade, just keep trying. When you think you have a perfect job it will probably be a level 3 1/2 - 4.
