Tar and Gravel Roof Application Pictures |
This Procedure and Picture Application is intended to Aid in the Application and Is Not Sufficient for Warranty Conformance, Inquire for a Detailed Application Procedure and a Warranty Registration & Conformance Certificate before Application of Any Coatings. |
GETTING STARTED All coatings must be stirred manually or mechanically before being used (except for PERMAPATCH). Do not let products freeze. Do not use any of these products at temperatures below 45 degrees Fahrenheit. Apply all products to dry surfaces only and do not apply products when they will be subjected to rain, high humidity or heavy dew before they have had enough time to dry (check Product Data Sheets). Do not thin any products unless specifically mentioned in this Application Procedure or Product Data Sheets. VISUAL INSPECTION and REPLACEMENT

| STEP#:2 PRESSURE CLEANING High Pressure Blast entire roof surface with at least 1500 P.S.I. of pressure using a water and chlorine solution (approximately 1 quart chlorine to 5 gallons of water). Thoroughly remove all dirt, oil, grease, residues, mold, mildew, algae and any other surface contaminants. Severe mildew requires a stronger concentration of chlorine. When roof is completely cleaned, rinse with water only. Let roof surface dry at least 12 hours before continuing. PERMAKOTE and PERMAKOTE PLUS has excellent mildew resistance, but this product WILL NOT kill mildew already on the surface. |

| STEP#:3 GRAVEL TREATMENT Use a push broom to level off the remaining gravel to achieve a roof surface even with the slope of the roof. Do not leave any piles of gravel or low spots. Remove all extraneous debris off entire roof surface. |

| STEP#:4 PRIME COAT Apply PRIMER (PERMABOND) using 1- brush, 2- at least a one inch nap roller, or 3- at least a 1 gallon per minute, 3,000 P.S.I. piston type airless sprayer with a minimum tip size of .025 tip. Remove tip and gun filters before starting. When Spraying or Rolling PRIMER, it must be applied perpendicular to the slope of the roof; example: If the slope of the roof runs from North to South then the coating will be applied spraying from East to West. This will be the start of a checkerboard application pattern. Apply the PRIMER at a rate of 75 -100 square feet per gallon covering the entire roof surface. Wet film thickness of 10-12 mils wet resulting in dry film thickness of 4-5 mils. Let PRIMER dry at least 12 hours before continuing. |
|
| STEP#:5 FIRST COAT of FINISH/TOP COAT Be sure entire surface is clean and free of all moisture. Be sure the entire area to be coated is primed, if not, then spot prime as needed. Apply PERMAKOTE® or PERMAKOTE PLUS® using 1- brush, 2- at least a one inch nap roller, or 3- at least a 1 gallon per minute, 3,000 P.S.I. piston type airless sprayer with a minimum tip size of .027 tip. Remove tip and gun filters before starting. When Spraying or Rolling PERMAKOTE® or PERMAKOTE PLUS®, the first coat of PERMAKOTE® or PERMAKOTE PLUS® must be applied perpendicular to the coat of PRIMER to achieve a checkerboard pattern. Apply the first coat of
PERMAKOTE® or PERMAKOTE PLUS® at a rate of 75-100 square feet per gallon per coat over
the entire roof surface. Wet film thickness of 12-15 mils resulting in dry film thickness
of 8-10 mils. Let dry at least 12 hours before continuing. |
|
| STEP#:6 SECOND COAT of FINISH/TOP COAT Be sure entire surface is clean and free of all moisture. Be sure the entire roof area is completely coated, if not then, spot coat. Apply PERMAKOTE® or PERMAKOTE PLUS® using 1- brush, 2- at least a one inch nap roller, or 3- at least a 1 gallon per minute, 3,000 P.S.I. piston type airless sprayer with a minimum tip size of .027 tip. Remove tip and gun filters before starting. When Spraying or Rolling PERMAKOTE® or PERMAKOTE PLUS®, the second coat of PERMAKOTE® or PERMAKOTE PLUS® must be applied perpendicular to the first coat of PERMAKOTE® or PERMAKOTE PLUS® completing the checkerboard pattern. Apply the second coat of PERMAKOTE® or PERMAKOTE PLUS® at a rate of 100-125 square feet per gallon per coat over the entire roof surface. Wet film thickness of 12-15 mils resulting in dry film thickness of 8-10 mils. Let dry at least 24 hours before your Final Evaluation. |
|
| STEP#:7 FINAL EVALUATION At this time a detailed evaluation of the completed job will determine the quality of the workmanship and whether strict application specifications have been met. The entire roof surface must be completely coated & sealed. Be sure to check that all roof areas are completely coated and sealed under permanently placed roof items such as roof top air conditioning units. Divide roof into 1,000 square feet sections and randomly check one spot in each section for a dry film thickness of at least 20 mils. Remember to touch up the penetration made by the dry film thickness gauge. If specifications have not been met, determine how much material will be required to meet specifications and recoat. Check dry film thickness again until specifications have been met. |
