First a bit of background, i really enjoy home cinema which i have been doing for about the last three years and particularly enjoy the diy aspect of it and learning about how it all works without being to techy. I have made the merlino and twisted snake power leads and then when i got my first projector Sanyo Z2 i made a screen out of black out material over a woden frame. When i first projected an image on the bo material i wasnt that impressed as it seemed to glow and looked washed out so i firstly painted it icestorm 6 but it still wasnt good enough so i painted it a mix of 5 and 6 to much better effect i.e the glowing had gone and the blacks were now quite dark. As this screen was my first effort and i had started to get the upgrade bug, i wanted to buy a fixed screen and had pretty much settled on a permawall hccv from da-lite which weighed in at about £600, then i came accross the Goo System and the diy in me just had to give it a go. I ordered 6mm mdf board 84inch x 48inch and 1inch x 1inch wood strip 84inch long from a wood merchant. Then i bought two paint rollers two paint trays and three smooth gloss roller heads. I then ordered the Goo, Digital Grey Base Coat with Digital Light Grey top coat both x 1Ltr, i also ordered the 2inch flock tape. The Goo base coat is quite thick with the top coat being very thin, but both are quite easy to roll imo. Painting the Board I rolled the mdf board with two coats of normal wood undercoat leaving an hour between each coat. I then thoroughly cleaned the roller tray and used a new roller head to roll three coats of the base coat, leaving an hour between each coat. I then left this for 24 hours to dry thoroughly, and so i could then do the top coat in normal light and with the lights on so i could see any potential roller marks. The top coat was rolled the next day again using a new roller and tray, the first coat still showed the base coat so i applied two other coats, again leaving just over an hour between each coat. Tips on painting would be to definitely have a very light environment so you can see any roller marks, be very careful when overlapping coats and dont over apply. Finishing I left the final top coat to dry for about another five hours before attempting to move the screen. I then no nails and screwed the 1.5inch x 1inch strip wood to the back top of the screen and screwed hooks into this wood for the picture rail wire. The next day, to ensure that the goo was thoroughly dry, i applied the flock tape as border, 2inch at each sides and 1.5inch for top and bottom giving a viewable screen of 80inch by 45inch. The flock tape has the advantage of giving a black border and also covering the screw holes, i then positioned the screen and set the pj back up. Conclusion/Recommendations The finished screen colour is lighter than my old screen i would say it is about the same lightness as icestorm 6, not same grey colour though just the same lightness. When i first projected onto my Goo screen i was amazed by how bright the colours were in relation to my old screen, i can even use the projector with ambient light which i couldnt do with bo material but could do with icestorm 5/6 mix. The only colour that is not any better is the black level, i could have probably got deeper blacks had i gone the digital grey top coat route as opposed to the light grey route but i have made my screen to last a few pj upgrades not just for the Z2. I was reasonably happy with the icestorm 5/6 mix but i have now realised that yes that infact does give a deepish black but it does also darken all of the other colours in the spectrum and by a considerable amount. Also with the Goo screen door is far less of an issue, scenes where i could just view screen door i can no longer see any or see far less and only if i go looking. The colours seem far more natural and the picture seems to have more depth to it or more of a distinct 3d effect. My room also has cream ceilings and with the Goo screen there just seems to be far less light shining on the ceiling and onto the walls than there was with the icestorm 5/6 mix? The only real downside at the moment is that i do have two roller streaks down one side that stand out during certain light scenes, even though i was very very careful when rolling. Searching avs a few people have had this problem but these do dissapear/reduce over a few weeks as Goo apparently can take several weeks/months to cure. Also for anybody thinking of doing this for a screen size similar to mine i would just buy 1ltr of base coat and 0.5litre of top coat. Notwithstanding the roller streaks i am really glad i opted for the Goo system as i now have a very professional looking fixed screen that gives a very nice picture and has cost me £170 as opposed to £600.
