✅Asphalt pavement is dry and swept or blown clean of loose debris (broom, leaf blower, etc.)

✅Temperature is above 50°F (10°C)

✅PPE is available (gloves, safety glasses, high-visibility gear, close-toed shoes)

✅RePlay+ is shaken or mixed thoroughly before application

  • 30 minutes for 275-gallon totes
  • 15 minutes for 55-gallon drums
  • 5 minutes for 5-gallon pails and 1-gallon jugs
  • 1 minute for 1-quart bottles

✅Application rate is set at 1 gallon per 600 sq ft or up to 1 gallon per 450 sq ft

✅Traffic control plan in place (cones, flaggers, signage as needed) and caution is practiced around vehicles and pedestrians

Method 1: Backpack or Handpump Sprayer

What You Need:

  • Clean backpack or handpump sprayer with a fan-tip or cone-tip nozzle
  • RePlay+ product, measured volume appropriate for the project

Steps:

  1. Site Prep: Sweep or blow off all loose debris. Blot the surface using a towel to make sure the surface is dry.
  2. Pavement Temperature: Use a temperature gun to gauge the surface and make sure it is above 50°F
  3. Fill sprayer: Mix RePlay+ thoroughly in the product container. Use a high shear blending blade to properly mix RePlay+. Pour the mixed RePlay+ into the backpack or handpump sprayer tank. Prime the spray applicator as recommended by the manufacturer. 
  4. Spray Application: Walk at a steady pace, spraying side to side in smooth, even passes.
  5. Overlap: Slightly overlap the spray pattern to avoid streaking or missed sections. 
  6. Watch for puddling: Use a broom or roller to spread out excess product if needed. Do this immediately, since RePlay+ will begin penetrating and bonding immediately. 
  7. Return any unused product back to the manufacturer's container and seal tightly. 

💡 Use backpack or pump sprayer for tight spaces like curbs, corners, cul-de-sacs, seams and joints, or test strips. BioSpan's vehicle-mounted Spray System also includes a spray wand and hose to reach irregular areas.

Method 2: Spray System (Flatbed Truck or Compact Unit)

What You Need:

  • A clean BioSpan Spray System (flatbed or compact units), calibrated appropriately
  • RePlay+ product in 275-gallon totes (for the flatbed system) or 80-100 gallons (for the compact system)

Steps:

  1. Site Prep: Sweep or blow off all loose debris. Blot the surface using a towel to make sure the surface is dry.
  2. Pavement Temperature: Use a temperature gun to gauge the surface and make sure it is above 50°F
  3. Prepare the spray system: Ensure pump, hoses, and spray bars are clean and functioning. Make sure fittings and clamps are tight and sealed. Ensure that all appropriate valves are open/closed before running the system.
  4. Prep RePlay+: Mix RePlay+ thoroughly for 30 minutes within the tote using a high shear blending blade before use. 
  5. Calibrate flow rate: Target rate is between 1 gal per 600 sq ft (0.015 gallons per sq yd), or up to 1 gallon per 450 sq ft (0.02 gallons per sq yd). Adjust vehicle speed and pressure accordingly. May slowly close the product return / recirculation valve to adjust pressure.
  6. Application: Switch on the appropriate spray booms from the cab control system. Once the vehicle is in motion, switch on the Master control to start spraying. 
  7. Avoid stopping mid-pass to prevent streaking or over-application.
  8. Post-Application: Once the spray line has been switched off and the vehicle is parked, close off the valve to the RePlay+ product container and make sure the top is sealed tightly for storage.

💡 Use a cone truck or follow vehicle with arrow board for safety on roads or in lots.

Cleanup & Aftercare

  • Flush all spray equipment clean of RePlay+ residue. 
  • Flush BST Cleaner through the spray system to clear nozzles, hoses, pumps, and tanks. May want to flush a second time to efficiently clean the system of the RePlay+ pigment. 
  • After BST, flush the spray equipment using a more concentrated MG Degreaser solution by diluting with less water (within the recommended range).
  • Clean tools and equipment immediately after use. May use BST Cleaner or diluted MG Degreaser for exterior sprayer surface cleaning
  • Avoid rain or irrigation for at least 2 hours after RePlay+ cure. 
  • RePlay+ Cure: Wait 1 to 2 hours before foot traffic, 24 hours before heavy vehicle traffic.
