Ambient Light Rejecting Projector Screen Paint

How to Use Ambient Light Rejecting Projector Screen Paint

Once applied to your wall, our Ambient Light Rejecting Projector Screen Paint is ready for use as a projection surface after 24 hours, once the surface is fully dry. Simply set up your projector as needed and aim towards the painted wall. We recommend ensuring your projector is calibrated correctly. Check the application guide for details.

What surfaces can Ambient Light Rejecting Projector Screen Paint be applied to?

Ambient Light Rejecting Projector Screen Paint is suitable for use on plaster, wallboards, wood, metal concrete and composites effectively any smooth surface. For interior use only; for exterior use, see our outdoor projection paint.

Do I need to prime the surface before applying Projector Paints?

We recommend applying ALR screen paint onto a previously primed or painted surface. Prime bare, untreated surfaces with one coat of White Primer.

How do I remove ALR projector paint from the skin?

In case of contact with skin, rinse skin with warm soapy water.

What do I do if I spill the ambient light rejecting paint?

Ambient Light Rejecting paint is water based so it can be cleaned using water.

How can I clean my ALR screen?

Ideally with compressed air which can be purchased in aerosol format or dab your surface slightly damp with a warm water cloth.

What is gain value?

Gain measures how well a screen reflects light back to the viewer, compared to a standard matte white screen with a gain of 1.0. A higher gain reflects more light for a brighter image but narrows the viewing angle, so viewers need to sit more directly in front of the screen. A lower gain gives a wider viewing angle but a dimmer picture. The right gain depends on your room, with factors like ambient light, screen size, projector brightness and seating all playing a part.

Why is gain important for projector screens?

Gain affects the brightness of the projected image and the quality of viewing angles. It determines how well the screen reflects light and impacts the clarity and width of the viewing angle.

Does a higher gain always mean a better image?

No, a higher gain projector screen doesn't automatically guarantee a better image quality. While it can provide a brighter image from certain angles, it may result in diminished brightness from other perspectives. Higher gain screens typically have a smaller viewing angle.

How do I determine the ideal gain for my projector screen?

The standard gain for a projector screen is 1.0, which ensures equal brightness from all sides and is visible from multiple angles. However, the ideal gain depends on the viewer's preferences and the specific environment. Other factors to consider are ambient light conditions, projector specifications and distance from the screen surface.

What are the pros and cons of high gain screens?

High gain screens offer clear and visible images in bright settings, enhance visibility in dark conditions, reflect minimal light from walls and ceiling, and are effective in eliminating light from fabric screens resistant to general lighting. On the downside, they have a reduced viewing angle for viewers not in the middle, require viewers to sit directly opposite the screen for optimal brightness, may not be bright enough for larger audiences due to restrictive viewing angles, and are not ideal for outdoor viewing.

What are the pros and cons of low gain screens?

Low gain screens provide a more expansive viewing angle for larger audiences, diffuse light evenly across a wider angle for an equal viewing experience, and reduce projector brightness for indoor settings. On the downside, they are not ideal for outdoor viewing due to reduced brightness, reject some light from the projector, and may not provide ample contrast to view all images clearly.

Does the Ambient Light Rejecting screen paint work with blended projections?

Yes. Our projection screen paint is designed for blending multiple projections onto a single surface, delivering the precise colour accuracy, uniform brightness and even light diffusion needed for smooth transitions between images. It also lets you cover large areas without the cost of physical screens, turning any wall into one continuous surface for blended displays.

Does the ALR screen paint work well with both 2D and 3D Projectors?

Our entire range of paints is compatible with both 2D and 3D projectors, ensuring optimal performance regardless of the projection mode. When projecting a 3D image onto our paint, it seamlessly delivers the intended effect, creating an immersive viewing experience when paired with 3D glasses.

How is ALR Screen Paint Polarity Preserving?

3D projectors work by projecting two slightly different images which overlap on the screen. These images are passed through special optical filters which results in the light being polarised in a different way for each of the projections. When you view the two images through special 3D glasses, each lens blocks one of the images, meaning that your left eye sees one image and your right eye the other image.

It's therefore really important that the projection screen you use does not change the polarity of the light if you are using a 3D projector. All of our paint products are "polarity preserving" which means that the image you see will be exactly the same polarity as is intended, preserving the full 3D effect.

Why are our Projection Paints Acoustically Transparent?

The Sound Absorption Coefficient (SAC) measures how much sound energy a material absorbs as sound passes through it, and it varies with the frequency of the sound waves. In our tests on a 12mm gypsum board, both the unpainted and painted board recorded the same range (α = 0.04 to 0.07). Because there is no difference between the two, our paints are acoustically transparent and do not affect how sound passes through the surface.

What type of projectors can be used with ALR screen paint?

ALR Screen is suitable for use with projectors above 2000 lumens.

What is the gain value of Smarter Surfaces ALR projection paint?

The gain value for Ambient Light Rejecting screen paint is 0.71 @ 90°.

Is ALR paint safe?

Yes, ALR paint is completely safe to use. It has very low-VOC, is solvent free, PFOA & PFOS free, and isocyanates free.

This paint meets the highest environmental standards and has been independently certified for Fire performance and VOC. As with any paint product we recommend wearing gloves during application.

Is ALR paint isocyanate free?

Smarter Surfaces Ambient Light Rejecting Paint is 100% free of Isocyanates and solvents. Unlike some poorer quality products on the market, we do not use isocyanates in our ALR paint or any of our products, which are hazardous to health. It should only be used by trained professionals who apply rigorous safety procedures.

What personal protective equipment should I use when applying ambient light rejecting screen paint?

Use the gloves supplied in the kit while applying ALR screen paint. In addition, safety glasses should be worn. As with any painting process, ensure the room is ventilated.

Is ALR screen paint flammable?

ALR screen paint is not flammable and is certified for fire performance making it certified for use in schools and offices. It has a very high flashpoint above 158 degrees fahrenheit.

Can ALR paint be applied around people?

Yes, it is completely safe to apply ALR paint around adults and children as it is certified as a low-VOCand low odour product. This paint does not contain any isocyanates which means it is extremely safe to use around people.
