Features
DESCRIPTION: STOP HEAT is a water-borne high-performance coating solution that blocks the absorption of solar heat gain into any external surface. Normal paints heat up from exposure to the sun. STOP HEAT is specifically designed with ceramics to keep your surfaces cool. Once applied by brush, roller or spray, STOP HEAT significantly reduces surface temperatures resulting in substantial comfort through reflectivity and emissivity. STOP HEAT is both tough and flexible, with a low permeability to resists corrosion and surface deterioration. Used on buildings, RV’s, boats, equipment and more.
Characteristics:
- Easy to apply – brush, roll, spray
- Keeps surfaces cool – proprietary ceramics
- Fast cure – 2 hr. overcoat @ 70F (21C), 40% humidity & direct sunlight
- Low VOC – Tested 21 grams per liter
- Non-flammable – water based
- Easy to clean – soap and water
- Mold & mildew resistant
TYPICAL APPLICATIONS:
- Metal roofs & walls
- Mobile homes and RV roofs
- Shipping containers
- AC unit shell, exposed metal ducting

Recommended Primers:
- Non rusted galvanized roofs requires no primer
-
Rusted metal requires RUST BASE primer
(Minimum 2 coats, each coat applied at 200 ft2 per gallon) -
For concrete use RUST BASE as a primer to seal the surface
(Minimum 2 coats, each coat applied at 200 ft2 per gallon) - Tar, Plastic, TPO, PVC, Vinyl or EPDM requires AUTO PREP
SPREAD RATE: Proper thickness can be achieved in 1-2 coats, but STOPHEAT should always be applied to a wet mil thickness of 17 mils wet / 9.3 mils dry (431 micron wet / 236 micron dry). Each gallon covers 95 sq. ft./ 8.82 sq. m.
Technical Informations
SURFACE PREPARATION: Surfaces should be clean, dry and sound. Existing surface dirt, salts, oil, tar, grease and film must be removed prior to application of STOP HEAT. STOP HEAT may be applied to other surfaces: metal, masonry, and wood following preparation procedures recommended according to manufacturer’s specification sheet. Use RUST BASE as a primer when needed on metal and concrete surfaces. Refer to RUST BASE technical data sheet for overcoat window. Modified bitumen, asphalt roofing, PVC, TPO and single-ply membranes must be primed with AUTO PREP. Please note: If any existing paint or coating is not firmly bonded, the existing paint or coating may fail and the surface will require the removal of all existing paint by power wash or abrasive blasting before the application of STOP HEAT.
APPLICATION INSTRUCTIONS: STOP HEAT can be applied by brush, roller or airless spray equipment. Mix by hand/mechanical for three minutes, and then apply evenly using the cross hatch method, up-and-down, side-to-side motion to build up your thickness. If spray equipment is used, carbide steel tips (.031) are recommended. IMPORTANT: ALL filters must be removed to prevent sifting of ceramic particles (sprayer and gun). Temperatures must always be a minimum of 5 degrees F above the dew point during application. Surface must be completely dry before applying.
CLEAN UP: Remove any uncured coating or overspray by wiping with mild soap and water or solvent. Follow solvent manufacturer’s directions. Freshly cured product is removed with sandpaper or wire brush. Gloves and safety glasses are always required during set up, application, and clean up.
SPREAD RATE: Proper thickness can be achieved in 1-2 coats, but STOPHEAT should always be applied to a wet mil thickness of 17 mils wet / 9.3 mils dry (431 micron wet / 236 micron dry). Each gallon covers 95 sq. ft./ 8.82 sq. m.
Questions and Answers
-
Does STOP HEAT come in different colors?
Yes, but because they contain ceramics, light earth tone colors work best.
-
What color produces the best performance?
White, because all low density ceramics are naturally white in color.
-
How does STOP HEAT block solar heat load?
Block all three sources of radiational solar heat, by an average of 95%.
-
Can I apply STOP HEAT directly on new metal?
Yes, as long as the surface is clean and free of oil residue.
-
Can I apply STOP HEAT on rusted metal?
Not without Rust Base as your primer
-
Can I apply STOP HEAT on an RV roof?
If its plastic, TPO, PVC, EPDM or rubber roof, then you will need Auto Prep as your primer before applying STOP HEAT.
-
Can I apply STOP HEAT on a flat roof?
Yes, with an approved waterproof top coat and must have structural integrity with water drainage. No ponding water.
-
How do I calculate the spread rate for STOP HEAT?
For corrugation you will need to add minimum 25% or more depending on the height and width of the corrugation. Contact Coatable for more details.
-
How can I apply STOP HEAT?
Brush, Roller 3/4, 1/2 or 1/4 inch roller, or airless sprayer (1.5 gallon per minute). For a smoother appearance and more control during application, use 1/4 inch nap roller and apply in two even coats instead of 1 coat.
-
What is the maximum and minimum temperatures to apply STOP HEAT in?
50F to 170F.
-
What if I am applying in very high humidity?
If very high humidity above 65% AND limited sunlight or cloud cover, then must wait until direct sunlight cures the coating before you can topcoat with STOP HEAT or any other coating.
-
What if it rains after I apply STOP HEAT?
If bubbles are seen do not puncture, wait until direct sunlight to dry down the excess moisture on its own. If heavy rain is expected or experienced within 24 hours of application, there may be some loss of coating thickness as the coating has not yet firmed up and the coating will rehydrate and lose surface film.
-
Once cured, can I walk over a roof coated with STOP HEAT?
Yes
-
Can I apply STOP HEAT on concrete?
Yes, but you will need a base coat because concrete is porous and will absorb STOP HEAT and show shadows within the color
-
Is STOP HEAT Flammable?
No, Stop Heat is water borne and completely no flammable and low VOC.
-
What if I get STOP HEAT on my skin?
Clean with soap and hot water.
-
What type of personnel protection should I use when applying STOP HEAT?
Use a nose covering, gloves and safety googles.
-
Can I mix by hand or electric drill mixer.
If you mix by hand, use a strong stir stick for about 5 minutes, or drill mixer for about 1 minute.
-
Can I add my own tint to STOP HEAT?
You must use a water base tint, not other type of tint will work, and only in light colors.
-
Storage Life
3 years shelf life if its sealed. If unsealed, and over time the water within the coating has evaporated and the film is dry/thick then you may proceed to add up to one liter / quart of clean water per 5 gallon bucket. Do not add more than one liter/quart per 5 gallon bucket.
Customer Reviews
Disclaimer: The effectiveness of STOP HEAT will vary based on color, location, climate, and time of day.- CJC J.Verified BuyerRated 5 out of 5 stars1 week agoAmazing product - works as described
I live in a 1200 sq ft modern home built of metal, epay wood and glass. Located in central Texas it has become impossible to cool in July-September with temperatures reaching over 100 every day. The metal heats up and becomes a radiating “furnace” where it’s impossible for the AC to keep up or cool. This product was purchased to try and keep the roof from getting so hot and keep the metal beams from becoming the radiator furnace. It works great! Initially I got half painted with only one coat and curiously shot IR temps from the inside at the heat of the day. There was already a 10 degree difference between the side with only one coat and the unpainted side. Reading the reflective side of the roof there was a difference where the paint was thicker and the thinner coat, so 2 coats are a must for best results . (Instructions recommend 2 coats)
- JDjanell d a.Verified BuyerRated 5 out of 5 stars2 weeks agoWater Cistern
This product works amazing. We used their primer and stop heat on our above ground water storage cistern about a year ago. It has helped drop our water temps by 10-20 degrees in the summer. We live in AZ and our water cistern gets very hot with the summer sun beating in it. Great product, affordable and easy to use.
- ALAndy L.Rated 5 out of 5 stars3 weeks agoGreat paint
Great product. We used to coat the top of a 40' office container down here in South Florida. It lowered the inside temperature considerably.
We would definitely use it again.

- EPEric P.Verified BuyerRated 5 out of 5 stars1 month agoEven better than expected
It's not often that a product exceeds your expectations, but this coating certainly does. The (aluminum) roof of my van would get so hot that it was affecting adhesives and insulation touching it. This coating actually made the inside so cool that there is a substantially lower temperature. It also has a nice look to it. This product has been the best money spent so far on the project.
- EElliottVerified BuyerRated 5 out of 5 stars2 months agoWorked great
I used it on the corners of my custom rv box. Temps dropped a ton. I couldn't touch the interior aluminum before, now it's barely above the interior temp.
- PDPeter D.Verified BuyerRated 5 out of 5 stars4 months agoStop Heat worked extremely well
Living on the Gulf Coast on Corpus Christi Bay with high summer winds and extreme heat and humidity. We painted the entire side of our large house facing east with two coats of Stop Heat to lower heat penetration including sealing all fasteners and seams. We then top coated with a yellow Sherwin Williams paint to match the rest of the house. The temperature on the interior walls dropped by several degrees including sealing out humidity. Stop Heat worked extremely well and we are extremely satisfied with the results.
- JGJerry G.Verified BuyerRated 5 out of 5 stars6 days agoStop heat works
I believe the product is performing as advertised. Painted an east facing wall and the heat stopped radiating to our interior.
I painted a bare aluminum window frame as well and it had the greatest difference in heat, went from 127° to 95°, in the sun on a 95° day using an infrared heat gun.
- DWDavid W.Verified BuyerRated 5 out of 5 stars1 week agoWorks. Period.
Put it on a dark bronze colored aluminum sunroom where the metal would get so hot you couldn’t touch it (we live in SE Florida ). Two coats covered the wall framing and sheet metal bottom. Now it stays cool to the touch and when it’s not the 5 months of August here we can use the room comfortably. I plan on getting more and doing the roof sometime over the winter.
- RCRaymond C.Rated 5 out of 5 stars2 weeks agoA unique product !!
I wasn't aware of such a product; and was pleasantly surprised that it was available to meet my exact needs.
I used it to create a barrier between the inside & outside garage wall space; which was not insulated when the house was built.
Heat from the afternoon sun caused heat transfer to the inside wall; where sensitive electronic equipment was located. This created a potential for premature failure of said equipment.
The use of HEAT on the outside wall prevented this transfer.
- CICharlie I.Rated 4 out of 5 stars2 weeks agoCooling my evaporative cooler
I used Stop Heat on my rooftop evaporative cooler over a year ago. Seemed to improve cooling capability in last year's and this year's unsual heat. It is a durable finish so far.The rough surfaceof the coating attracts dirt especially when performing maintenance. A company rep, named Aaron, says I can apply a satin or gloss enamel on top of the Stop Heat to get a cleaner surface with no more than 10% loss in effectiveness.
