97 Fibered Aluminum Roof Coating

97 Fibered Aluminum Roof Coating

Available in: 1 gallon cans,  5 gallon pails & 55 gallon drums

KARNAK #97 Fibered Aluminum Roof Coating is made of selected asphalts and pigment flakes of pure aluminum blended with refined solvents and reinforcing fibers for heavy duty service. When KARNAK #97 Fibered Aluminum Roof Coating is applied to the roof, the aluminum flakes leaf to the surface providing a reflective metallic shield over the base of the coating.

Preparation & Application

SURFACE PREPARATION:
Prepare all surfaces by sweeping clean of dust, dirt, oil and loose particles. Repair all cracks and blisters by spreading KARNAK #19 Ultra Rubberized Flashing Cement over the damaged area, then embed KARNAK Cotton, Glass or Poly-Mat reinforcement and apply another coat of KARNAK #19 Ultra Rubberized over the entire patch. New asphalt roof surfaces should weather a minimum of 90 days before being coated with KARNAK #97 Ultra Rubberized Fibered Aluminum Roof Coating. However, KARNAK #97 Fibered Aluminum Roof Coating can be coated onroofs 3 to 5 days after KARNAK asphalt emulsions have been applied. Badly weathered or alligatored asphalt surfaces should be primed with KARNAK 100 Non-Fibered Emulsion or 220 Fibered Emulsion prior to coating with 97 Fibered Aluminum Roof Coating. Allow emulsion primer to cure a minimum of 3-5 days before application of aluminum coating.

APPLICATION:
KARNAK #97 Fibered Aluminum Roof Coating should be spread uniformly over the roof surface. Care should be taken not to overwork the coating during application. This could have a damaging effect on the leafing of the aluminum. Pour the correct amount of aluminum coating to cover a given area and work it in one direction. Be sure to mechanically mix the aluminum coating thoroughly before using. KARNAK #97 Fibered Aluminum Roof Coating can be applied with a soft roof brush, roller or spray.

NOTE:
Discoloration will occur in areas where KARNAK #19 Ultra Rubberized Cement is not allowed to dry a mini mum of 60 days.coating. After 60 days,  recommended application temperatures are 50° Fahrenheit and rising. Must not come in contact with any type of moisture within 24-48 hours after  application.

Coating Modified Bitumen Membranes with Aluminum Coatings:
KARNAK recommends coating torch-applied modified bitumen membranes as soon as possible after the membrane is installed

KARNAK’s experience, laboratory and field tests, as well as NRCA, RCMA and ARMA reports, indicate that aluminum coating will reduce the combined effects of ultraviolet rays, heat and moisture, which, especially on APP modified bitumens, enhance exudation that can cause discoloring and delamination of any surface coating.
COLD-PROCESS SYSTEMS AND COATINGS, EITHER EMULSION OR SOLVENT BASED, SHOULD ONLY BE INSTALLED ON DECKS WITH POSITIVE DRAINAGE. PER NRCA, (NATIONAL ROOFING CONTRACTORS ASSOCIATION) “THE CRITERIA FOR JUDGING PROPER SLOPE FOR DRAINAGE IS THAT THERE BE NO EVIDENCE OF STANDING WATER ON THE DECK 48 HOURS AFTER IT STOPS RAINING.”

Caution/Care of Tools

CAUTION:
Do not use near open flame. Avoid breathing solvent fumes and prolonged contact with skin. Do not take internally. If swallowed, do not induce vomiting. Call a physician immediately. Keep out of reach of children. Keep container covered when not in use. Do not thin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying.
CARE OF TOOLS:
Equipment may be thoroughly cleaned after use with mineral spirits, taking the necessary precautions when handling combustible materials.
