Now we just need to do it right.
Exactly. And what NOT to do is to continue trying to paint over the obvious defects.
While you have any degree of Contrast to use in locating all the defects, you should purchase a pre-mixed gallon tub of Dry Wall compound, and mix an appropriate amount of that @ 10:1 with water. Stir it up until you have a semi-thin paste, and using a 3" knife, ladle that onto a 10" Mud knife in the middle, in as wide a lump as that equals the defect to be covered.
This is called a Curry Finish coat. It fills minute depressions and scratches without adding excessive amounts of mud onto surrounding areas.
You apply such at a 45 degree "upward sloping" angle across the affected area, doing so no more than twice. Then if your pressure was correct, the thinness of the Mud will allow it to flow ahead of the knife, leaving only depressions filled and most excess wiped away.
You then leave it alone! Let it get "dusty" dry to the touch. Sand with a fine grit sponge using the lightest of pressure and a sweeping stroke, but focus on the outer edges where the mud stops. You only want to pass over the center just enough times to reduce any ridge or "nifkin" that is apparent. If that area looks completely filled under a BRIGHT direct light shown directly from the side across the area, your done. Otherwise, repeat. If they truly are small defects, this will eliminate them.
When you try to paint defects out, unless you apply an exceedingly heavy coat (Orange Peel City!!!
) with expectations of sanding laboriously, You stand the risk of only "coating" the problem.....and also the surrounding areas, but you still have the same discrepancies.
Either way...by Heavy coats and sanding, or apply several different coats, the risk of apparent issues after so much additional work is pretty much a risk not worth taking.
Little else in Dry Wall Mud work is easier than skim coating a pre-finished wall over a "spot" area. And once the areas are dealt with, a complete, ultra-light sweep sanding equalizes everything so very well, the Primer will go on just as if the wall was as smooth as glass. No need for heavy "Fill" coats that might require sanding. But if after two light primer coats you do choose to lightly sweep sand, your end resulting surface will be all the more ideal.
Now the dig,
This is a construction site. Why on Earth can't this FnEasy 6 instance benefit from the ultra quick, inexpensive, and "easy' application via a Wagner Control Spray? Realistically speaking, there is virtually NO instance where construction methods and proper materials results in more noticeable improvements in appearance and performance more so than what is compared to the difference between spraying with an electric Spray Gun like the Wagner Control Spray, and what one has to do/put up with when trying to roll "perfection"....or even close to it. I believe the tables have turned.....leastwise in a great many instances. All that remains is for the "Spray" application to get some degree of equal press and forbearance, and less discounting as a "hard" or "expensive" proposition..
Tiddler, as the Champion of Easy, you owe it to your Minions to get experience in this domain. Cost has been slashed. Skill level reduced to "walking and some degree of "Eye to Hand Coordination".
In this particular instance when something is being done from scratch....with what can be done with a Wagner, and for what cost and the time /skill involved, Spraying should not have been discounted or left unmentioned.
We all strive for the best. Rolling is an option....not an "End All", and if a superior method can be used, and is not, then one must question the processes and priorities leading up to such a project. To me, I see only good things for FnEasy coming from the realizations ahead for you should you take this prompt. As for Dr Doom. Well....he gets the best part of it all, no doubt.
