New projection screen paint

I'm a real home-theater nut and when I built my new house on the lake last year, I built a small dedicated home-theater room on the lower level. I already had a Sony VPL-10HT front projector and a 108” 1.3 gain Da-Lite projection screen. In my new dedicated room I found the screen to be a little bit too large for viewing from the front row of seats (yes, I have three rows of tiered seating!), and I would also have had to mount my projector a little too far back in order to fill the screen.

So I decided to buy a new, smaller screen (90” or so). I was decided on a Stewart GrayHawk screen, which is slightly gray instead of white. This is said to improve both color rendition and black level for LCD projectors. However, that baby would cost around $1500, and that is for a fixed wall-mounted model (double or triple that for electrically operated!)

Just as I was about to plunk down my hard-earned cash on a Stewart, I discovered a new product that sounded too good to be true. This product is called Screen Goo, a special paint designed for creating projection screens. It comes in two tints of gray to help LCD and DLP projectors. They even have a version for REAR projection setups. Initially I was rather sceptical but after reading the rave reviews and seeing that the product is being used by Caesar's Palace in Las Vegas, I decided it was worth risking $160 to give it a try. To top it all off this is a Canadian product so having it shipped to me was going to be cheap and fast. I ordered from Goo System's website and had my two cans (base and finish) of light-gray goo 3 days later.

So last weekend I decided to give it a try. I removed my huge Da-Lite screen from the wall, turned on my projector, and used masking tape to mask-off the exact perimeter of my projector's picture. The stuff  is really easy to apply with a regular paint roller and it sure wears its name well as it has a much thicker goo-like consistency than regular paint. You first have to make sure your surface is clean and smooth, and they recommend using white primer first if the surface is dark-colored or not in excellent condition. You have to take some care in applying the goo as it dries very fast and you have to ensure that you do not create any “banding”. The simple tips and tricks provided in the instructions made that an easy job, even for me! I proceeded to apply two coats of base, followed by two coats of finish (a special acrylic paint). You only have to wait 1 hour in-between coats, so the whole process took about half a day.

Once the last coat had dried, I fired-up my home theater system, inserted the LOTR-II disk, and turned off the lights. Wow! I was pleasantly surprised: this $160 gooey stuff surpassed my $1400 Da-Lite screen in every way! The image is brighter, the viewing angle is VERY wide, the colors are richer, and the light gray tint definitely does help with the black level deficiencies of my LCD projector. Now all I have to do is finish the edges of the screen with a black fabric frame and some curtains, and I'm all set! Sorry Stewart Filmscreens!

This is the kind of product I love. Well designed, easy to use, affordable, and high-performance! Just the kind of thing we canucks need to keep ourselves warm and entertained on those long winter nights.

Highly recommended: ***** 5 out of 5 stars.

BTW, I have a 108” 16:9 Da-Lite screen for sale :)

This is neat - definetely bookmarking it. How does the wall look when the projector's off (just the paint there)?

Yes, it just looks like a white rectangle right now. Since it is just part of the wall and nothing sitcks out, you can do anything you want with it. I plan to put a black frame around it and then some motorized curtains that open when I turn on the projector.

The beauty of this all is that it is extremely flexible. You can make screens of virtually sizes and just about anywhere you have a flat surface! Goo Systems tells me that it actually keeps getting better for about 6 weeks as the acrylic cures. I'll be reporting on my findings again then!

Well let's see... I am an architect at Avanade Canada, does that leave me time to work for Goo Systems? I think not!

We have plaster walls that have rather high relief. Would we need to plaster over the texture prior to putting on the base coats? Is all this info on their website?

Good question, I'm not sure! I would ask the folks a GooSystems. My wall was in a brand new house and only had a bit of texture, so it wasn't a problem. The Goo itself does have some texture, which I think contributes to the wide viewing angle by dispersing the light a little bit more, but then that probably reduces gain a bit too.

Our company is expanding our home automation area into home theater applications. I was considering whether we should resell this product line. I want to get some in for myself to test it first, but your review is encouraging.

Thanks for Sharing!

What roller should be used? Or is it better to Spray Paint this Goo Paint? I heard if you roll it leaves roll marks....

There are lots of advantages to using a projection screen paint like Goo Systems. With that kind of screen material for your projector screen you have full control over the size. However, I do want to point out an alternative DIY home theater screen from DIY Theatre. It is a liquid polymer screen that uses non interference pigments which are exclusive to these screen and a formulation that will reflect a higher range of UV light. You can read more at this link: http://www.diytheatre.com/why_diy_movie_screens/index.htm .
Good luck with your DIY projection screen and your home theater project.

Thanks a lot for the information. I am currently considering doing precisely the same as you for monetary purposes so I was happy to hear that the picture quality is excellent. Would it be possible to see any images that you have with your previous da-lite versus the goo systems? I was hoping they would have some on the goo site, unfortunately their site appears to be down today.

I just received some my bottles of gray lite. Will do a 100" screen by roller applicaton in the next week. Will give my opinion after that. I am concerned that the web site is down, hopefully they are not out 0of business.

Hi! I am pleased to read all the valuable comments and tips since I will paint the Goo screen this week-end on my wall. It was a textured wall (in french we call it "Crepi") so I first had to ask the painter to smooth it out perfectly to ensure the best impact. On the plaster I set on layer of regular white wall paint, which I let dry for a day. Now I will start with the two base coat layers, and the two topcoat ones. I must admit I am a little afraid of the result since painting is not so much my prime talent, but your messages encourage me a lot! I will post the results of the experiment on Monday.

Hi, I have now laid down the four layers of the Goo Systems screen paint – and it initially seemed easier than thought. The base coat layer went smoothly on the white paint prep layer, and it dried well. Then came the interesting bit. I was rather anxious about the top coat layer, fearing that the roller I had was not the proper one and would not result in a smooth surface, even though it was a “short hair” one. After laying down the first layer, the result seemed fine, smooth, and even. I noticed though that when projecting white light on the screen there were some zones where some worm-like traces could be seem, like strips but very foggy. I imagined that could be solved in the second layer, and proceeded with that 2 hours thereafter. The end result was really nice, again, still I am unsure whether some of the remaining “traces” will remain after the six weeks complete drying period. Hopefully yes – otherwise the result would be mitigated in my own case.

The last issue I got is not linked to Goo, I suspect, but when I removed the protection tape around the screen area from the wall, it took away some of the underlying paint…

Some advise I would give based on this week end’s experience for those who will roll the paint are:
- Remove the protection tape while the last layer is still wet, otherwise risk of taring away part of the Goo layers
- Use strong light on the screen area when painting, it helps noticing the major unevennesses early on. Also move away from the screen to have another viewing angle.
- Change the roller on each layer – cleaning one for the four layers will probably result in some form of paint dilution

Happy rolls!

Sounds like you had a pretty good experience with a screen paint. You now realize one of the key benefits is that you can control your screen size. With diy projection screen material from www.diytheatre.com you will also find some other very important advantages. Most important is the non interference pigments that are exclusive to our projector screens. You can see more of the benefits at http://www.diytheatre.com/why_diy_movie_screens/performance.htm All of the screens from DIY Theatre come complete with the rollers which are made to exact specification. If you think about it all projection screens from any manufacturer start out as a liquid and then applied to cloth or cured into a vinyl. With a DIY Theatre screen we sell the polymer direct to you with no shipping or middle man and you are the one who saves. Good luck to all those who are building a home theater.
