Screen Help (Paint)

Need to know the throw distance, but at this conjjecture it's pretty obvious you need more than the 1.0 gain or less a UPW w/Gray would provide to achieve a truly dynamic image. Using a paint that will augment Contrast (...improving Black Levels without crushing Whites...) and provide at least 1.2 to 1.3 gain would be just the ticket. Ergo....RS-MaxxMudd LL

You "can" Roll that particular mix, but spraying is so much better and pretty much assures you that the 120" diagonal image as seen from just 12' away will look pristine.

A excellent Sprayer can be had for under $50.00, and in fact I know of at least one member with a slightly used one to sell.

Post up again if you want to proceed with a course of action that will result in more than you really thought you could expect for the effort and expense you outlay.

Are you going to use that paint? Or are you referring to the Screen's construction?

That particular formula is just a odd attempt to copy a older MMudd SE Mix that originated on this Forum, made darker still by adding extra Gray base and it's not as good a performer as you need in any case. RS-MaxxMudd LL will do a much better job. I did not feel the need to move you toward any really advanced formula....and I still don't. But you "DO" need gain as well as at least some modest degree of contrast enhancement.

Good luck on finding a Good Black Velvet locally at even 2x this price. http://www.syfabrics.com/View.aspx/Plush-Triple-Velvet/Black-Plush-Triple-Velvet/681/264

Natch! Good luck!

If your spraying, it should be almost the same consistency as thin Tomato soup. When strained through a nylon Sock Filter, it should just fill the bottom of the filter about 1/3rd up, then continue to drain at the same rate you pour the paint in. (...about the same rate you pour out Milk into a small glass....)

The 20 oz of water is almost too much....but not if it meets the aforementioned criteria. If it does seem to filter through too rapidly, simply leave the paint container open about 3-4 hours, stir, the re-check.

Water tends to evaporate out of such mixes pretty quickly.

I don't know what substrate your using, but if your mix is really all that thin, and your painting onto a "sheet' of some material, it may be advisable to Roll the screen on a horizontally flat surface. Keep the surface "wet", and don't overwork the paint (...spread it too thinly...) or you will get roller marks.

If the wall is the substrate, follow the same advice only be very careful to not "overload" the roller.

Guy....I know we state that RS-MaxxMudd LL is "roll-able"...and it is, but we are really talking about the lessor chance of the metallics being an issue, not that the paint itself is applicable for most to roll effectively. Unless the prepared surface is very smooth...almost glass-like, and you can use a high quality 9" Fabric (...not Foam) Roller that is specifically made for "Smooth Surfaces (3/16" Nap) (...and have the skill to use it correctly...) it's at best problematical that you'll make it through with no issues.

I'm not one to herald doom and despair, nor advocate that people spend more than necessary, be it time, effort, or money. But a 120" screen demands the best possible effort, and quire frankly, the cost of Rollers, a decent Tray (...they are NOT all the same...) works out to be about 1/2 the cost of a $50.00 Electric HVLP sprayer. That difference can mean the difference between virtual perfection and a real disappointment.

And....the amount of paint you have will barely be enough for three good "Rolled" coats. You don't have much fudge room going for you, and that always pains me to see happen with a member going into what can be and should be...a project with such great potential.. I worry about you guys like a Mother Hen.

A Sanding of the primed surface using a Large Fine Grit Sanding sponge (...in the Drywall Section @ HD...) until you have smoothed the surface down evenly is all that is required.

Spray instead of Roll? All I can say is that Spraying will always produce the smoothest, most consistent results. One has to really over-apply a "Duster Coat" onto semi-dry paint to get any Orange Peel.

When rolling even a paint that is meant to be rolled, the end result is always wholly dependent on technique (skill) as well as paint viscosity and drying conditions. Sprayed Dusters apply so little paint per coat, (...relying on a gradual layered build-up...) that the finish is almost "Car-like" smooth at close inspection.

With a sanding as described followed with a sprayed application (...5 Duster coats avg.) it's virtually assured that your end result will be as perfect as the Gods of DIY Screen Making will allow. So make a Burnt Offering of those damnable Rollers, genuflect to the No-Name found here ( http://www.ebay.com/itm/GRACO-HV2900-39-CFM-450W-HVLP-House-Paint-Spray-Station-Machine-System-Painter-/230791007590?pt=Paint_Paint_Supplies&hash=item35bc374d66 ) and all will bow to your glorious Screen's visage.
