Also if I read correctly is it 1/4 nap for primer, and 3/16 for RSM LL mix rolling on ?
Thanks in advance
So this is how you Roll, eh? Well Roll on Brother.
The mix should be just fine wit the amount of water that is initially prescribed within the mix. Only when spraying is additional dilution usually called for.
2 coats of Primer, both lightly sanded is correct. And you might have to sand between the 2nd and a 3rd coat of RS-MaxxMuss LL as well dependent on your rolling rechnique.
My 1st question is this: Will the amount of RS-MM LL generated by the recipe be adequate for a 130' diagonal screen, whose future owner is rolling on a absolute minimum of 2 coats, but most likely will require 3. Each vertical row almost demands a freshly loaded roller, because you absolutely have to keep a "Wet Edge" on the leading side (and the Top or Bottom) of each prior Row to come back onto when resuming. You do NOT try to ecck out the last vestige of paint in the roller onto the wall before reloading.
Yes...a 3/16" "Fabric" Roller is required for the Finish paint. A GOOD one...Lint Free. And the Paint Tray should be a metal or plastic one that does NOT have the Bumps or pronounced Channeling ridges that some do. When your using a low nap roller, the pattern of such things can transfer onto the painted surface, and there you go....having to work the paint more that desired.
The more your work the paint (...and the harder you seem to have to press on the roller to smooth thing out...) the more likely you are to get roller marks. Using very smooth, long, "wet" strokes will always help prevent such nastiness. Of course this does not mean you want to put up a dripping, heavily loaded roller....just a fully loaded, saturated one that doesn't have paint dripping or sliding off it.
Be sure your Roller Wand is also a good one, one that has ball bearings and spins very easily. That is essential as well so as to avoid "sliding".
In the end, rolling on any "High Contrast" paint (...all darker colors...) requires care in using proper rolling technique. RS-MaxxMudd LL isn't all that dark...actually it's very light in a White-ish Silvery hue, but it does enhance contrast, and it is going to be used to create a Screen that will be continually "stared at", so you simply cannot afford to have any vertical lines left from roller edges pop up during brightly lit content.
Lastly, roll with a light touch. Pressing down hard or unevenly at all is fraught with danger. Not only will it cause potential roller marks....but if you create too smooth (ie: Flattened Out) and condensed a surface, a enhanced Glossiness could occur that would allow the metallic particles to get arrayed in a Flattened manner, flat side to the projector.
I know I seem to be making a big issue about this rolling business, but ever since the metallic content went up precipitously, issues such as the above simply have to be addressed. Just use a careful "Eye" and correct any unevenness while the paint is still wet. Consider & take each row as being a finished piece of work, and build the next row right on top it's leading wet edge.
Good luck. Get'ter Dun !
