ThermaCels - Insulating Paint Additive 1 Gallon Package

Therma cells work great for some applications but many people seem to miss-interpret the benefits of using it. I used it on my school bus conversion's interior walls and did some testing on it. I used Rust-Oleum bedliner and did a thick two-coat application for reference. I would highly recommend a thicker coating like a bedliner for use with this product. I found that my walls were noticeably cooler after applying the coating. My 1st control was an un painted area which was too hot to hold a hand to after sitting in the sun all day, 2nd control was bed liner with no Therma Cells and then I had the area I applied it to. The second area was about 4 degrees cooler than the first but still noticeably hot to the touch. The Therma Cell area was only another 2 degrees cooler than the second, but it was not warm to the touch. My conclusion is that it seems like Thermacells are very effective at lowering the HEAT CAPACITY of a coated material, but not necessarily it's actual temperature. This means that thermacells will make the coated area a poor condutor of heat to the air around it, but won't necessarily work wonders on the actual temperature of the material itself. I'd definitely purchase this again as it seemed to cut down radient heat and touch-surface's (perceived, not really actual) temperatures noticeably.

I researched the living daylights out of this product so I knew exactly what we were getting into. The only trouble that we had was trying to find a professional painter that would agree to mix it with the paint and apply it to our home. Big strike out. We found a handyman That took no issue. He mixed it with the paint that we purchased according to the directions. We did have to buy him a new nozzle because the product did wear his nozzle down significantly. It does not look any different than if we painted without the product however it reflects/rejects/bounces back heat that would normally come from our hot Arizona sun. We purchased enough to mix with the primer that was first applied, and then mixed again the recommended amount with the paint that went over the primer. It looks truly amazing and does not provide any indication that there is anything in the paint. That really mattered because I didn’t want our home to be sparkly or have some weird additive looking effect. It just simply looks professionally beautifully painted by the handyman that did the work. I helped him throughout much of the process. I highly recommend this product. It is like having a secret barrier or shield over your home.

This stuff does help. I have a block wall which faces west in phoenix az. I tested several areas one with white paint, one white with additive and one the medium brown of the original house color. Original house was 148 degrees plus the white alone dropped temp 20 degrees and finally the white with one coat of additive dropped temp by 30 degrees . at 10 to 15 extra dollars per gallon I figure here in the hottest city in the country its gonna be well worth the money even if its on 10 - 15 degrees. With our insane heat and an uninsulated block wall every bit helps!

This product is the game changer I was searching for. We live near a huge military airbase- with fly overs daily, along with near highway traffic. Just to make sure this product worked I took several decibel reading each day of week. After a full week after painting with Lowe’s interior Valspar reserve & mixing this product in with a concrete blender-the paint & mix expanded my paint supply. When I started to apply with a spray gun that product malfunction- I just used a 18” rough to smooth roller the mixture of this ceramic powder& paint was amazing it also dries quickly. After an hour the room was noticeably quieter. After the full week- my living room decibels was down 35-40 with the planes or traffic from highway. The kitchen/ dining room was 32-35 lower. The bathroom we did previously with door closed it was 40-45 quieter since it’s in the middle of the home. We did the walls & ceiling with this product. Also house was built in 2017 walls were a cheaper stucco plain Jane basic yellow. This product can be mixed with satins, gloss will show tiny dots like sand. We love this product with egg shell makes everything brighter too. Can’t wait to see difference with electric bill with AC & heat.

Worked great in basement. Much more comfortable and perfect for tv room sound. Did find texture on stairwell to ruff. So just painted over it without additive. Still works as published just doesn’t deaden sound as much in stairwell now. I would recommend.

I live in South Florida and have a Florida room with a flat roof. Over the years, we have attempted to make this room more efficient thermally and acoustically. We had a thick 3M heat reflective security film added to the windows, which wrap around the whole room. That helped a lot. We then added a new wall mounted AC unit and that helped cool the room more efficiently. A few years ago, we had the roof painted with Black Jack® ETERNA-KOTE® 100% Silicone Roof Coating. Again, that helped. But this room is still warmer than the main part of the house, so when we decided to paint the flat roof again with the Black Jack® ETERNA-KOTE, I had the 2 gallon size Hy-Tech ThermaCels paint additive and decided to add it to the paint even though it was 5 gallons of paint. The Hy-Tech additive still helped lower the heat coming through the flat roof, but what amazed me is the fact that we had a few major downpours and we can barely hear the rain through the roof. I am so impressed that I am tempted to get another 5 gallons of the Black Jack® ETERNA-KOTE and add the proper amount of Hy-Tech additive to it. We will be getting our home painted when rainy season is over and I will be adding Hy-Tech's product to all of my exterior paint. In fact, we decided to go ahead and paint the exterior of the Florida room, so I will be adding the Hy-Tech to that and after, I will add another review. Really impressed with Hy-Tech's product!

Ordered this to coat exposed ductwork to help insulate it to prevent condensation from forming. I coated the ductwork with 4 thick coats of paint with this additive and this product didn’t help at all insulating, to prevent condensation.

Ok... I have mixed feelings about this product. One the plus side, it works. We used it on the roof of our school bus to RV remodel and there is a noticeable difference in temperature inside. On the negative side, we sprayed it on like we spray painted the whole bus. The problem is that regular paint mist/over spray floats off into the air where is paint mixed this product goes all over your project. If it's the rest of your roof, fine. But in our case it was the hood and sides of our bus. I had asked a question about this product and was advised about it having a suede like texture (it doesn't, suede is soft. This is like sand paper. I'm not sure how we will wash our bus roof in the future, since everything snags on the texture) which is why we didn't use it on the whole body. Unfortunately, it is on the body of the vehicle, just not uniformly like the roof. It looks more like dirty areas in our paint job, or the gloss is missing from the texture. Another negative is paint gun clean up. It is impossible to get all the ceramic "micro beads" out of your paint gun. I ended up buying a new paint gun because I didn't want to risk adding any more texture to the finish areas the were supposed to have none. Ultimately, I would use the product again, but with a roller or cover the whole project and protect it from over spray. I think in this case it's less about the product itself and more about the developer/manufacturer not providing adequate/accurate application information.
