I'm not saying drywall isn't a great substrate, I'm saying I
can't do a good job with the stuff. BTW, you can find Sintra as big as 6' x 10'.
But not easily. I recently did a search through my Sintra supplier and there was only 3 locations in the US with such stock.
Drywall Screws or Nails don't back out unless they were put in improperly (no grab into lumber) or too shallow (...didn't get set deep enough to look "dimpled"...) and the "cap' of th Mud wasn't sealed properly. Those things happen when a Drywall hanger doesn't care much, expects the Drywall finisher to cover his crappy work, and the Drywall finisher doesn't care enough to notice / do anything to correct the situation. We DIY'ers are by nature more meticulous, and unlike Contractors, we have to "live' with our work. Kirnack
, I know you have it in you to do it right, you just have to know how to do it right and make sure no step is done....not right.
If someone is willing to be patient, and follow instructions to the letter, they can mud / Tape / Finish / and smooth Drywall to perfection. Or close enough so as to not matter. But as stated, you have to follow directions to the "T". Even the "Skimming" of a large area with Drywall Compound to create a completely even and identical surface overall isn't hard....just comes with the need for one to be exacting.
Choosing Drywall is a case where one sacrifices one's time and effort to save a goodly amount of cash...or more importantly, to have the size screen surface he really wants. If a existing "Flat" but inappropriate wall surface exists, overlaying 3/8" Drywall and attaching it with Screws can be a wondrously easy and affordable route to take.
This offer stands....anyone who cares to try can look to me for a "Step by Step" instructional via Email / Pm. The only requirement being that they document their effort and post up everything in entirety for others to benefit from.
ANOTHER option is using Sintra in the same manner as 6mm can also be joined in the same manner as Drywall. However the center of each sheet must be glued to the underlying wall. also, the adjoing edges must be "tapered" using a Utility knife so as to create a "valley" at the juncture of the two sheets, and (...as a important note...) one should absolutely always
use the adhesive Mesh-type Drywall tape, and never use "Quick Set" Drywall Compound. Lastly, just as with Drywall, one must lightly skim the entire surface of the Sintra with Compound and sand lightly. 2x in fact.
Do all that with either Sintra or Drywall and you can achieve a perfect, blemish free surface on with to paint.
