DESCRIPTION:

Roof X Tender™ 500 White Elastomeric Cool Roof Coating is a flexible, white elastomeric roof

coating designed to cool roof surfaces and extend roof life. Roof X Tender™ 500 White Elastomeric

Cool Roof Coating provides a reflective barrier that prevents the sun’s heat and destructive UV

rays from deteriorating roof surfaces. It also blocks heat build-up in roof membranes, which leads

to a reduction of roof temperatures and reduced cooling costs.

PREPARATION:

All surfaces must be dry and free of dust, dirt, oil, loose granules, gravel and peeling paint, and

all other foreign matter. Roofs must have proper ventilation and drainage. Rusty metal must be

cleaned with a wire brush and primed with Metal Primer before the application of this product. Pressure

washing the entire surface is recommended for best results (use only a wide fan spray tip). If unavailable,

use a garden hose with a spray nozzle to clean & rinse the roof surface. Repair all leaks, cracks, and seams

with an Elastomeric Rubber Patching Compound and polyester repair fabric in accordance with

product instructions. Surfaces previously coated with aluminum, asphalt or tar should be allowed to

cure for a minimum of one summer season prior to coating with this product. Surfaces with mildew

growth or stains must be cleaned with a bleach solution (2 parts water to one part bleach). Be certain

all surfaces are thoroughly rinsed and dried prior to applying the coating. The product can be spray applied

with a professional quality airless sprayer. DO NOT THIN.

When installing new BUR or modified

system, it is recommended to wait a minimum of 60 days prior to the application of acrylic coatings to

prevent asphalt bleed-through. The roof should be washed free of any foreign contaminants, oxidation,

dirt, etc. before proceeding.

APPLICATION:

Protective clothing and eyewear should be used during the application of these products. Surface and

air temperatures must be a minimum of 50°F. DO NOT apply if heavy dew or rain is expected

within 24-48 hours. Apply on a clear, sunny day in the morning hours with a long bristle brush, 3/4”

nap exterior paint roller or professional airless sprayer. First, treat all seams, joints, penetrations,

curbs, drains, flashings, and other repairs according to details using Roof X Tender Mastic, Polyester, and Repair Tapes. Then apply two (2) uniform coats over the entire surface, at the rate of 1.5 gallons

per square per coat for a total of 3 gallons per square. Two full coats are recommended for all

applications. Dries for recoat in 4 hours and fully cures in 24-36 hours at 70°F & 50% relative

humidity. Higher humidity, thicker films, poor airflow, and lower temperatures will increase dry

times. Apply the second coat perpendicular to the first coat.  The application should be completed a minimum

of 4 hours prior to sunset. Peeling or delamination may occur in areas where ponding water or poor

drainage exists. All roof surfaces should maintain proper drainage. DO NOT allow stored products

to freeze. Apply in accordance with NRCA Guidelines. For the most recent guide specifications visit

FOR BEST RESULTS: Apply Roof X Tender™ 300 Rubber Roof Seal WB prior to application or

white coatings. For worn surfaces, embed one or more layers of polyester into Roof X Tender™ 300

Rubber Roof Seal and then apply Roof X Tender™ 500 White Elastomeric Cool Roof Coating.

SUNLIGHT: Reflection of sunlight from light-colored or white roof coatings necessitates the use

of dark glasses to protect the eyes during application. Sunblock should also be used to prevent

sunburn and skin damage.

NOTE: Use of polyester in waterways, low areas and drain areas in conjunction with Roof X

Tender™ 700 Premium White Acrylic Cool Roof Coating will help the coating resist standing water

and last longer than without polyester reinforcement. See Roof X Tender™ 700 for instructions on

the application.

PRECAUTIONS:

Do not allow stored products to freeze. Protective clothing and eyewear should be used during

the application of these products. When transporting this product, ensure that lid is tight and the pail

secure and upright. Do not allow the pail to tumble as this may cause the lid to loosen and leakage to

occur. Do not transport on passenger seats or inside the passenger compartment of any vehicle.

Store products in the cargo area of the vehicle, and secure them overprotective cloths to prevent damage due

to accidental spills. Do not store at temperatures above 110°F. Seal the container when not in use. This

manufacturer also disclaims liability for flat surface application where poor drainage or ponding

may prevail. Do not reuse empty containers. For exterior use only. Not for use on EPDM or some

single-ply membranes.

CLEAN-UP: Warm water and soap immediately after use.

NOTE: If the roof becomes hot (over 100°F) during the application, lightly mist the roof surface with

water spray to prevent the coating from drying too fast. Remove any excess or puddling water prior

to coating. If roof surfaces become soiled as they age, due to the elements, elastomeric can be

cleaned with mild water and bleach solution. Excess scrubbing should be avoided. If coloring

is desired, a typical addition of 3-4 ounces per gallon of Universal colorant can be added, which

will result in light pastel colors. Note – Color tinting will disclaim a warranty. Yearly inspection and

maintenance will greatly enhance the life of the coating.
