Create your own cosmic masterpiece on any plain white ceiling (flat or textured). Amazingly it remains discreet and ‘virtually’ invisible during the daytime (certainly on a textured ceiling) yet glows magically all night long. 

Breathtaking luminous artwork like this is enjoyed by everyone, grown-ups and children alike and best of all, its easy to do.

There can be few uses of Starglow paints that are more impressive than a Cosmic Ceiling.

Create Amazingly Cosmic Effects

Your questions answered

Yes. The items and designs we have included in our kits can be used many times. Replacement paints are available to buy on this web site.

The glow-in-the-dark technology used to create Starglow paints is the most advanced in the world which means a Starglow FX Cosmic Ceiling can last for over 20 years.

You may have seen glow-in-the-dark toys and gizmos that only glow for a few minutes. The technology used in Starglow paints is so good, that the best of the paints (green) can glow for over 20 hours. With a good charge of UV light (Black light), your Starglow FX Cosmic Ceiling should glow gently all night long gradually becoming dimmer as the hours pass.

Yes it can but please do not rely on it for use during the hours of darkness!
It does not really matter how many hours of daylight the paint is exposed to (indoors or outdoors) as during the time it takes daylight to become the dark of night (usually around 2 or 3 hours) most of the stored energy has been burned-off in glowing whilst it is still too light to see it! 

The reason is simply that Glow Paint (and other glow products) are actually glowing all the time and do not save-up all their energy waiting for it to become dark. 

We recommend at least one UV Blacklight unit in the room and turned on a good 20-30 minutes before bedtime in order to ‘charge-up’ the glow paint / stars etc so they will glow brightly and look their best when it matters most.

This depends on the individual doing the work. Typically your first ceiling will take you a few hours as you become familiar with the techniques involved. Once you are comfortable with doing them, a typical cosmic ceiling should take a few hours. We would recommend doing this over 2 nights; the first night allowing you to study the ceiling in the dark and decide if it needs more paint / effects adding etc.

There are sufficient paints included to create a medium – large cosmic ceiling. However if your ceilings are relatively small and you use the paint sparingly, you should get two small ceilings out of the kit. You can always order more paint to apply later if you wish to increase or alter the cosmic ceiling effect.

No. The underlying principle of a cosmic ceiling, is that it is created using special paints which are ‘off-white’ in daylight and therefore virtually invisible when applied to a white ceiling. At night with no light, the ceiling becomes a jet black background to a breathtaking cosmic vista.

Every cosmic ceiling will look different from the next. Like any piece of artwork, no two will ever be the same, also the ceiling in the photograph was fully charged before the picture was taken. This involves using a UV-rich blacklight to ‘energise’ the ceiling artwork. If you want your ceiling to look like the one in the photo you will need to use a mains powered blacklight to charge it up each night.

Without a full charge it takes on a dim more gentle ethereal effect, which whilst not as dramatic, is perhaps a better way to help encourage a good nights sleep. (See also next question / answer)

The paints used to create the ceiling charge-up on Ultraviolet (UV) light. LED bulbs do not give out much in the way of UV and the way to see the ceiling at its most dramatic would be to give it a good UV charge. Therefore we would recommend using a mains powered black light unit to properly charge up the ceiling.

We have included a basic mains black light bulb with each Cosmic Ceiling DIY kit to both help with its creation and afterwards to help ‘charging up’ the ceiling when you want your cosmic ceiling glowing at its best.

There are more powerful black light units available on the market if the basic bulb is insufficient.  Having said that, under low light (i.e. low UV) conditions and after a couple of hours, the ceiling takes on a more gentle, ethereal effect actually preferred by many. Whilst this ‘toned down’ version is less colourful, it is in many ways more realistic and soothing to the eye. So which ever version of your cosmic Ceiling your prefer; ‘soothing’ or ‘WoW’, your sure to be delighted.

If you can comb your hair while stood on a ladder, you have the ability to create a cosmic ceiling. They are really easy to do, are great fun and very rewarding.

Starglow paints represent many years of development to make a range of very high performance glow paints that are solvent-free, non-radioactive, non-toxic and virtually odorless.

As the Paints dry ‘off-white’ (or a very light green in some cases), when applied to a white ceiling, the finished cosmic ceiling should be ‘virtually’ unnoticeable under normal lighting. The Smart Paints used in the creation of Cosmic Ceilings are called Invisible, as they are made to be as daytime neutral as is possible and to blend into a white background. They are not ‘invisible’ in the literal sense of the word, and if applied to a smooth ‘matt’ ceiling would be far more apparent than if applied to a textured ceiling.

In many respects a textured ceiling is the ideal surface for a cosmic ceiling, as the pattern helps break up and hide the cosmic artwork unlike smooth flat ceilings which can reveal paint-on-paint in the daytime and in certain lighting conditions.

What are Glow-in-the-Dark paints?

Often referred to as glowing,  phosphorescent, illuminous, luminous or luminescent paint, these paints are essentially a clear polyurethane suspension containing microscopic photo-luminescent crystals, which absorb invisible UV energy from existing light sources and then re-emit most of that energy as visible light.  

This process happens in real-time so glow paints actually glow all the time, its just that in normal lighting conditions we cannot see this glow effect, but it does tend to give the paint a light greenish appearance. The energy the crystals do not re-emit immediately, is retained and slowly released as a gradually diminishing afterglow. Starglow paints can be recharged thousands of times and last many years.

Starglow Paints are made in the UK using the very latest in photo-luminescent technology, for a brighter, richer, longer-lasting glow.  

These high-performance, water-based paints are solvent-free and non-toxic.

Hi Glowtec,

Thank you for your products, they worked wonders & did the job perfectly.

I painted 3 ceilings to create stars & galaxies & my family were amazed!
My 2 boys are 7 & 10, there were bouncing on there beds with excitement that night & to see the reaction on their faces was amazing so thanks again.

I’ll try & sends pics if they come out alright.
