Restore existing asphalt substrates including BUR and Modified Bitumen
BUR (BUILT-UP ROOF)
1. Surface Prep
- Ensure that new BUR roofs have fully cured before attempting to coat. Curing may take 30-180 days, depending on type and manufacturer
- Wash with TSP substitute and water; rinse or power wash
- Remove loose granules
- Roof system must be clean and dry with surface temperature below 120°F at time of application
- All underlying materials must be fully cured
2. Repair & Seal
- Fill small ponding areas with Elastek® #505 Puddle Plaster or ERSystems® Quicket (Review TDS for cure times)
- Coat flashing seams with Elastek® 103 Crack & Joint Sealant and Polytek Fabric as needed
- Repair ply sheets, leaks, seams, and drains as needed
- Optional: For heavily worn roofs, apply Elastek® #500 Emulsion at 2 gallons per 100 sqft, allow emulsion to cure a minimum of 10 days. After cure rinse, allow to dry prior to priming
3. Prime
- Prime all exposed asphalt substrates with Elastek® #121 High-Tek Basecoat (Other asphalt substrates: Mod-Bit, Elastek® #500 Emulsion, Elastek® #505 Puddle Plaster, etc.)
4. Finish Coat
- Apply two coats of appropriate Elastek® finish coat
- Apply with 3/4″ or 1-1/4″ nap roller or airless spray
- Smooth Surfaces: Approximately 475 square feet per 5 gallon size pail per coat (approximately 100 square feet per gallon per coat). Apply two coats
- Rough Surfaces: Approximately 100 square feet per 1.5 gallons per coat depending on porosity and roughness of surface. Apply two coats
Modified Bitumen
1. Surface Prep
- Ensure that new modified bitumen roofs have fully cured before attempting to coat. Curing may take 30-180 days, depending on type and manufacturer
- Wash with TSP substitute and water; rinse or power wash
- Remove loose granules
- Roof system must be clean and dry with surface temperature below 120°F at time of application
- All underlying materials must be fully cured
2. Repair & Seal
- Fill small ponding areas with Elastek® #505 Puddle Plaster or ERSystems® Quicket (Review TDS for cure times)
- Coat flashing seams with Elastek® 103 Crack & Joint Sealant and Polytek Fabric as needed

- Optional: For heavily worn roofs, apply Elastek® #500 Emulsion at 2 gallons per 100 sqft, allow emulsion to cure a minimum of 10 days. After cure rinse, allow to dry prior to priming
3. Prime
- Prime all exposed asphalt substrates with Elastek® #121 High-Tek Basecoat (Other asphalt substrates: Mod-Bit, Elastek® #500 Emulsion, Elastek® #505 Puddle Plaster, etc.)
4. Finish Coat
- Apply 2-3 coats of appropriate Elastek® finish coat
- Apply with 3/4″ or 1-1/4″ nap roller or airless spray
- Smooth Surfaces: Approximately 475 square feet per 5 gallon size pail per coat (approximately 100 square feet per gallon per coat). Apply two coats
- Rough Surfaces: Approximately 100 square feet per 1.5 gallons per coat depending on porosity and roughness of surface. Apply two coats
