ROOF-KOTE‘s original biobased formula makes it easy to permanently seal and repair your roof!
A good choice for the environment
biobased ~ reduces energy usage ~ non-toxic
Roof-kote contains a proprietary blend of natural agricultural oils. Biobased products help reduce dependence on petroleum based products and provide markets for American farmers. Roof-kote White (an ENERGY STAR® qualified roof coating) reflects the sun's rays, reducing building temperatures and cooling costs. Roof-kote is biodegrable, non-toxic and VOC compliant...the best choice for your roof and the environment!
A good choice for your roof
instant waterproof protection ~ stops flat roof leaks ~ ponding water resistance
Roof-kote's natural oil formula forms an immediate watertight seal that locks out moisture. Roof-kote creates a vapor and moisture barrier that completely seals the roof surface. Unlike water-based coatings, Roof-kote can be applied when rain is forecast, humidity is high or when outside temperatures are as low as 40° F.
A good choice for your budget
one coat coverage ~ limited ongoing maintenance ~ save time & money
Roof-kote goes on in just one coat over most roof surfaces. Other coatings require multiple applications, at least two and up to five! Roof-kote seals and waterproofs in just one coat saving time, labor and money. Roof-kote is easy to apply and requires little yearly maintenance or recoating costs. Roof-kote can withstand attack by UV rays, mold & mildew and temperature extremes. For business property owners, roofing repair costs can be expensed immediately, unlike capital expenses, which have to be amortized over many years. Compare the real costs of keeping YOUR roof sealed and waterproofed and you’ll see why natural oil-based Roof-kote is the ONLY coating that makes real roofing dollars and sense!

Roof-kote can be used over many roof surfaces, including concrete, foam, well adhered water-based coatings, weathered tar and gravel, weathered asphalt, rolled roofing, compatible single-ply membranes, slate and tile. When used with Primer-kote, Roof-kote can be used on new concrete and new or unsealed asphalt. Do not use Roof-kote on rubber, EPDM or any questionable roof surface. Do not use Roof-kote on new concrete or new or unsealed asphalt unless surface is primed with Primer-kote. Before coating ANY roof, always do a test patch to check for compatibility, adhesion and soundness.

General Application Guidelines
Preparation: Surface should be sound, clean and dry. Remove flaking, peeling and loose material. If mold and mildew are present, they must be removed before coating with Roof-kote. Use a suitable fungicide cleaner or liquid bleach solution. Once the mold and mildew has been completely removed, rinse the surface with water and allow it to dry thoroughly before coating with Roof-kote. For proper maintenance, the roof can be power-washed with up to 3000 psi to remove mold and mildew as well as other dirt and air-borne contaminants.
Patching: Patch all seams, breaks, leaks and problem areas with Tuff-kote or Roof-kote and Tuffglass Fabric before coating.
Priming: Some substrates may require priming of the surface with Primer-kote prior to coating (including tar and asphalt and new concrete). Allow Primer-kote to cure for 24 hours before coating with Roof-kote. Contact factory for product specification sheet and more information.
Application: Mix product thoroughly before using. Do not thin. Product warranty is voided if product is altered in any way. Keep lid tightly sealed after opening to prevent skin formation, stir again before each use. If skin forms, remove completely prior to mixing. Apply one thick coat at 40 to 50 wet mils. Always use a wet film gauge to ensure the proper mil thickness has been applied. Temperature range for application: 40° F to 100° F for air, surface and material with a maximum humidity of 85%. Keep material at 72° F to 100° F for best spread rate. Forms immediate watertight barrier on all surfaces.
Cure time: Initial skin forms in six to eight hours; develops thicker set skin in 24 to 48 hours in good drying conditions (72° F and 50% humidity).
Final dry time will vary based on ambient temperature, weather conditions, relative humidity, application thickness, air movement and precipitation. Avoid all foot traffic until fully cured. Suitable for occasional/maintenance foot traffic only. Do not use on decks or high traffic areas. Roof-kote dries slowly, stays flexible and pliable under skin, never dries hard; cures to a tough, leathery finish.

Clean-up: Clean tools with mineral spirits. Dispose of containers properly.
Application Guidelines for Specific Roof Types
Concrete: New concrete surfaces should be tested for alkalinity prior to the application of Roof-kote. Treat alkaline concrete and concrete patches with a Muriatic acid and water solution or seal with Primer-kote. Apply one coat of Roof-kote at 40 wet mils.
Slate and Tile: Remove efflorescence. Treat alkaline stucco surfaces with a Muriatic acid and water solution or seal with Primer-kote. Apply one coat of Roof-kote at 40 wet mils. Make sure Roof-kote is applied evenly on all overlaps, with no voids or gaps in the coating.
Acrylic Elastomeric Coatings: Remove all failed coatings completely. Apply one coat of Roof-kote to secured surface at 40 wet mils.
Asphalt: Seal new asphalt with Primer-kote to prevent bleed-through. Apply one coat of Roof-kote at 40 wet mils. Allow extra material when coating granulated or rough surfaces.
Rolled Roofing: Check and repair blisters, patch all seams and joints. Remove all loose granules to ensure good adhesion, allow for extra material on rough or graveled surfaces. Seal with Primer-kote before applying Roof-kote.
