How to Use D/2 Biological Solution

Application Procedures

Always do a spot test sample before proceeding with project. D/2 works best when air and surface temperatures are 45°F or above. Use D/2 undiluted for best results. In the event of excessive plant exposure, rinse all plants and water in all planted ground areas.

Immediate Result Method

  1. Apply D/2 Biological Solution with a brush, roller, hand pump sprayer (garden style pump sprayer) or low pressure power sprayer.
  2. Allow undiluted D/2 to remain on the surface 10-15 minutes.
  3. Apply additional D/2 as necessary to maintain a wet surface.
  4. Scrub with soft nylon or natural bristle brush.
    DO NOT USE METAL BRUSH.
  5. Lightly mist with water and continue scrubbing.
  6. Rinse thoroughly with clean, potable water.
  7. Allow surface to dry to the touch then mist the surface with D/2 and leave it.

No Scrub/No Rinse Method

  1. Apply D/2 Biological Solution with a brush or pump sprayer to a dry surface. Do not pre-wet the surface.
  2. Allow to dry. Repeat if there are heavy biological stains.

D/2 works with the elements and results occur within one week to one month depending on severity of growth and weather conditions. The surface will become cleaner over time as the subsurface biological stains release.
