CONTRACTORS GUIDE Section 6 - PITCHED ROOFS
ROOF TYPE:
6-1 ROOF TYPE:
PITCHED ROOF (POSITIVE DRAINAGE)
90# MINERAL SURFACE COMPOSITION ROOF
SHINGLES OR ROLLED ROOFING.
PRODUCTS REQUIRED:

POLAR CAP STANDARD (PCS-108) or
POLAR CAP PREMIUM (PCP-108)
PLASTIC CEMENT (PC-107)
POLAR CAP RESATURANT (PC-103) is optional.

1. Power wash, broom and blower, or broom and water as required.

2. If loss of the mineral surface granules has resulted in a burn-out condition, apply a thin coat of POLAR CAP RESATURANT (PC-103) and allow for a sufficient cure time of 30 days minimum before proceeding.

3. Do not coat shingles which are not lying flat. If curling is evident, coating is not appropriate and will not deter additional curling. If damage is confined to an area less than 200 square feet, replace the shingles in question, then proceed. If damage is confined to an area of perhaps 25 square feet or less, the tabs may be nailed down with roofing nails, then use the 3 course repair (see section 3) across the nail heads.

4. Use the 3 course repair to secure vents, flashings, skylights, broken seams, etc. against leaks. Allow 24 hour cure time. Leave this on.

5. Shingles - Using a 1" nap 9" paint roller, apply POLAR CAP STANDARD (PCS-108) or POLAR CAP PREMIUM (PCP-108) roof coating rolling toward the ridge, pushing product against the shingle tabs. The first coat coverage rate should be at 1 1/2 gallons per 100 square feet. The second and third coats will be applied at 3/4 gallon per 100 square feet. Allow a minimum of 6 hours between coats; and 24 hours if possible.

5-A. Rolled roofing - Using a 3/4" nap 9" roller, apply the coatings at 1 1/2 gallons per 100 square feet. The second and third coats will be applied at 3/4 gallon per 100 square feet. Rotate direction of application each coat.

IMPORTANT - CURE TIME IS AFFECTED BY WEATHER CONDITIONS
(SEE SECTION 11-1)

6-2 ROOF TYPE:
PITCHED ROOF WITH POSITIVE DRAINAGE-BUR AND GRAVEL.
PRODUCTS REQUIRED:

POLAR CAP STANDARD (PCS-108) or
POLAR CAP PREMIUM (PCP-108)
PLASTIC CEMENT (PC-107)
POLAR CAP PRIMER/ROCK LOCK (PC-106)

1. Remove all loose gravel. Do not attempt to remove embedded gravel.

2. Power wash or broom and water. In areas where the roof is leaking, broom and blower.

3. Use the 3 course repair for broken seams, vents, flashings, skylights, etc.

4. Using a low pressure sprayer (garden type) apply a thin coat of POLAR CAP PRIMER/ROCK LOCK (PC-I06) diluted 1 part primer to 1 part water. Allow three hours cure time - surface will remain tacky. It will be milky in appearance when applied but will dry to clear. This procedure seals the partially embedded gravel to avoid problems when rolling out the roof coating.

5. Apply POLAR CAP STANDARD (PCS-108) or POLAR CAP PREMIUM (PCP-108) using a 1" nap roller. First coat application rate will be as much as 2 gal per 100 square feet depending on surface texture.

6. Second and third coats will be at approximately 1 to 1 1/2 gallons per 100 square feet.

7. Always allow for 3 1/2 to 5 gallons per l00 square feet for gravel roofs. Allow 6-24 hours cure time between coats (See Section 11-1)
