FAQ's
General Product Questions
What type of projectors can be used with ALR screen paint?
ALR Screen is suitable for use with projectors above 2000 lumens For attaining a cinema-quality experience, simply pair your ALR Screen with a projector of at least 2000 lumens. The brighter the projector, the more vibrant and crisp your visuals will be. So simply go for high lumens for obtaining the best results.
What is the gain value of Smarter Surfaces ALR projection paint?
Our ALR Projection Paint boasts a gain value of 0.71 at 90°, thus striking the perfect balance between contrast, brightness and wide-angle visibility.
Application & Usage
How to Use Ambient Light Rejection Projector Screen Paint?
Once applied, allow 24 hours for the paint to fully dry before use. Set up your projector as usual and direct it towards the painted wall. For attaining the best visual experience, ensure your projector is properly calibrated. Kindly refer to the product application guide for further guidance.
Does ALR screen paint work with both 2D and 3D Projectors?
Yes. So whether you’re watching a classic film in 2D or diving into an immersive 3D experience, Smarter Surfaces ALR screen paint delivers absolutely flawless performance. When used with 3D glasses, it ensures that depth, clarity, and vibrancy remain intact, thus bringing visuals to life exactly as intended.
Can I apply Ambient Light Rejection Projector Screen Paint to fabric?
Ambient Light Rejection Projector Screen Paint is suitable for application on fixed fabric surfaces and for refurbishing old screens. It is not advised for roll-up screens.
Surface Prep & Priming
What all surfaces can ALR Projector Screen Paint be applied to?
If it's a smooth surface, it's probably a great canvas for ALR Paint. This versatile formula works wonders on wallboards, wood, plaster, metal, concrete, and composites, essentially, any non-textured surface. However, it's designed for indoor use only. So for outdoor applications, check out Smarter Surfaces outdoor projection paint.
Do I need to prime the surface before applying the ALR Paint?
A good foundation makes all the difference. So we highly recommend applying the ALR Paint to a previously primed or painted surface. However, if you are working with a bare or untreated wall, then start with one coat of White Primer for attaining a flawless finish.
Cleaning & Maintenance
What is the easiest way to clean my ALR screen?
For a quick refresh, use compressed air ( that is available in handy aerosol cans) to blow away dust. However, if a deeper clean is needed, then just lightly dab the surface with a soft cloth dampened with warm water.
Functionality & Performance
Does Ambient Light Rejecting Screen Paint work well with blended projections?
Yes, Smarter Surfaces Ambient Light Rejecting Screen Paint works with blended projections. Also, we would like to mention that when merging multiple projectors onto a single surface, seamless blending is key. This is exactly where the ALR screen paint steps in.
Designed for precise colour accuracy, uniform brightness, and exceptional light diffusion, Smarter Surfaces paint ensures that blended projections appear smooth, without harsh edges or brightness inconsistencies.
So now get over those bulky and expensive physical screens. The paint can magically transform any surface into a stunning projection area, thus delivering a cost-effective and immersive visual experience for theatres, art installations, and large-scale displays.
How is ALR Screen Paint Polarity-Preserving?
3D projection works by displaying two slightly different images that overlap on the screen. Special optical filters polarise the light, thus allowing each eye to see only one image through 3D glasses, creating the illusion of depth.
However, if your screen alters light polarity, the 3D effect is lost. That’s why the polarity-preserving paint ensures the projected image maintains its original polarisation, delivering an accurate, crisp and fully immersive 3D experience.
Why are Projection Paints Acoustically Transparent?
Smarter Surfaces Projection Paints don’t interfere with sound, ensuring clear audio alongside great visuals. Testing on a 12mm gypsum board showed identical Sound Absorption Coefficient (0.04-0.07) before and after application, proving the paint doesn’t absorb or distort sound. Ideal for home theatres, auditoriums, and professional setups.
How does ambient light rejecting screen paint work?
This innovative Ambient Light Rejecting Projection Screen Paint uses unique pigment particle technology to scatter ambient light ingress from the horizontal plane which protects the projected light beam by reducing light interference.
