How does Koolcoat work?

Koolcoat blended in paint and applied as recommended becomes a reflective barrier to heat. Ordinary insulation resists the conduction of heat through a structure whereas Koolcoat reflects the sun’s energy away from a structure, thus avoiding heat absorption.

Will Koolcoat lower energy bills?

Based on studies and almost ten years of customer feedback about their results, radiant barrier paint coatings can save over 50% of heating and cooling energy usage. Results of course will vary depending upon the application of the coating and the daily routine through the structure.

How will Koolcoat save winter heating costs?

Heat travels to cold. With Koolcoat applied on interior walls and ceiling heated air is reflected away from the perimeter walls and the heat does not escape outside to the cold. Koolcoat on the interior results in uniformily heated rooms. Koolcoat all but eliminates “cold spots” and cold floors and warm ceilings, if applied correctly. Koolcoat helps maintain a comfortable temperature while using less heating energy.

What kind of paint should I blend with Koolcoat?

Koolcoat can be blended with all interior and exterior paints: Acrylic, latex, oil based, epoxy, urethane, etc. Depending upon the application a decision of paint quality must be made. For example, applying Koolcoat in the attic, an inexpensive paint could be used, however if you wanted to paint the exterior roof, a choice of a good long-lasting elastomeric paint would be in order.

Does it matter what color of paint I mix Koolcoat with?

Yes it does! After years of extensive informal research (customer feedback and personal experiences) we are beginning to believe that any paint color that requires a black pigment is going to affect the radiant barrier results of Koolcoat. The culprit as we see it is CARBON. Most if not all black pigments contain carbon. Carbon is a conductor.Radiant energy is an electromagnetic wave. Even with Koolcoat in the paint, the conducting effects of the carbon neutralize the barrier effects. The carbon attracts and conducts the radiant energy right through the coating as if the Koolcoat barrier wasn’t even present.

What surfaces of my structure should I paint with Koolcoat for maximum energy savings?

For maximum energy savings, Koolcoat should be applied both inside and outside. To get started conserving energy, try applying Koolcoat in an inexpensive paint to the underside of your roof decking. That application alone will lower summer temperatures in the attic, reducing the heat gain into the structure.

How much Koolcoat do I need?

Koolcoat is sold in pre-measured kits, designed for blending in one gallon, or as many five gallon buckets you may need to use. The exact amount of Koolcoat needed depends on how much paint your project will use. Coverage rates per gallon of paint vary depending on the type of paint and surface to be covered. On average figure 300 square feet of coverage per gallon of latex paint and 75 to 100 square feet for elastomeric roofing paints. So after calculating the square footage to be painted, figure the amount of paint required and purchase the correct kit of Koolcoat to match the gallons of paint.

How do I apply Koolcoat?

Koolcoat can be sprayed, rolled and for small areas, brushed. If spraying, an “airless” spray machine that develops 2000 to 3000 psi is required. You must remove all filters from the machine and use a large tip of .021″ or .030″. Make sure you have plenty of hose to reach all the areas you want to coat, and wear the necessary protective gear that you would normally use while spraying paint. To apply Koolcoat with a roller, once the Koolcoat is blended into the paint, simply pour into a roller tray and apply.

How many coats of paint are needed?

Depending upon the surface to be coated, two coats of paint with Koolcoat blended in are adequate for maximum energy savings. If the surface is quite porous, a primer coat may be necessary before the paint with Koolcoat is applied. Additional coats of Koolcoat add energy saving, and if later you cover the Koolcoat with plain paint, expect to lose some energy efficiency. A. The pre-measured kit of Koolcoat increases paint volume by at least 20%. By increasing the ratio of Koolcoat to paint, you will increase the reflectivity and thus energy efficiency, but first TEST a small amount of paint with the new ratio. Some paints can carry an added load of Koolcoat and still adhere well. Some paints may not carry the added material and won’t apply correctly.

But what if the color I really want has black in it and I can’t settle for anything else?

If your chosen color calls for black pigment in the tint recipe, there is a way to still get your color and eliminate the black pigment. Ask the paint guy if he will substitute Dark Brown for the Black pigment. Dark Brown is “burnt umber”, a clay and although it may take almost double the amount of dark brown compared to the black to develop the chosen color, the color will be very close.

Ok, I picked out a light-ish color, but how do I know if it requires black or not to get to my color?

Ask the paint tech to run the “recipe” for you. If your color requires black,drop down to the next lighter shade and run another recipe. Keep doing this until the black is not required, you move to another color, or the paint tech loses patience.

I want to spray my attic with Koolcoat, but the rental guy say’s his pump won’t support a .021″ tip. And besides his rental prices are high for the weekend. Do you have any solutions?

Let’s address rental price first. If you are going to be spraying your attic and you think it may take two weekends to get the job all done because it is too hot up there to do it all at once; here is one way to beat the rental prices and have your very own airless pump for future Koolcoat jobs. Go to gleempaint.com on the web and look for their factory reconditioned airless rigs. Most of the time they will have a rig you can buy for a price less than or equal to two weekend rentals. They ship fast and have wonderful support people. In fact their support people will also tell you that their 5/8 horse power pump will not support the .021″ tip necessary to spray Koolcoat. But here’s the reason they are telling you that. The factory matches a motor, pump and tip to optium sizes so when you are holding the gun a certain amount of inches away from what you are spraying, everything is correct to break the paint into the small droplets that will give you a beautiful finish. When you are shooting Koolcoat, all you really need is some kind of controlled paint-flow pointer. A car-wash wand would and has worked. Small tips will clog up and try your patience. When you are in your hot attic, all you want to do is shoot paint and Koolcoat as fast as you can. And then go back downstairs and cool off. So here’s my recommendation when talking to Gleem Paint, tell them you understand their concern about the “maximum tip size”, but you plan to shoot Koolcoat and would they please add a 421 or a 521 tip to your order? { What’s this 421? and 521? The “21″ designation is the tip size in “code”(.021″) and the “4″ or “5″ is code for the fan spray size by half. In other words, remember when the factory told you to hold the gun so many inches away from the substrate to get that beautiful finish? Well, the fan spray will either be 8″ wide (a code 4) or 10″ wide (a code 5)}

How do I reach those hard-to-get-to places in the attic with my spray?

Turn the tip around and “wash down” the far away areas. Yeah, you’re going to have paint dripping and running down rafters, and paint all over your nice painting clothes, but just remember you can actually get your attic down to the same temperature as outside air temperatures if you do everything Koolcoat recommends. And the first recommendation is to apply TWO COATS.

I did my attic, and now I want to spray my perimeter interior walls. How do I do that with the big tip? You said it was messy and it was in the attic, but I don’t want messy inside the house. What do I do?

Move or cover that you don’t want painted. And cover with the utmost care. Take your time. Prep is all important. Get a helper and a roller with a long handle. Mix your paint, get the pump primed then turn the pressure regulator down until your gun is shooting an adequate spray into an empty bucket. Start spraying with your helper right behind you “back-rolling” every square foot you just shot. The two of you can do a large bedroom in less than 20 minutes with ne coat, just in case you were thinking this was going to take forever. With the back-roller, all the drips, drapes and holidays will disappear and the finish will be as nice as if you were following factory rules for tip size.

How do I mix Koolcoat into paint?

Choose an area where no wind is going to disturb the blending process, Koolcoat is a microscopic powder and you don’t want it to become airborne. Wear protective eyewear and a dust mask. Begin by pouring the paint into a larger container (Koolcoat adds 20% volume), stir the paint thoroughly until it is well mixed and then slowly pour the Koolcoat into the paint. Stir until the blend is smooth with no clumps.

Are there any special preparations needed before applying Koolcoat?

Like with any other paint, a clean surface is necessary for good adhesion. Remove any dirt, scale, rust, oils, wax, etc. from the surface before painting.

Does Koolcoat change the finished texture?

The dried surface will have a slightly textured surface.

Can I apply Koolcoat to anything else?

Yes! Blended in high-temp paint Koolcoat can be applied to any hot surface (providing the paint is rated for the temperature in question). Steam pipes, boilers, hot water pipes, barbeque pits and engine compartments are just a few places Koolcoat can be used to insulate hot areas. Additionally Koolcoat blended with the correct type of paint can be applied to the exterior or interior of refrigerators, freezers, walk-in coolers and freezers, fish holds, ice merchandisers, or any other device that tries to maintain a temperature higher or lower than the ambient temperature.

What other properties does Koolcoat have?

Because Koolcoat is a ceramic based product, the finished surface will be harder and much more abrasion resistant than regular paint.
