D/2 Biological Solution

D/2 Biological Solution is an effective cleaner for removing harmful biological and air pollutant staining from building materials including masonry, marble, granite, limestone, brownstone, travertine, terra Cotta, concrete, stucco, wood, canvas and vinyl & aluminium siding.

Effective for removing environmental pollution, dirt, and staining from biological soils such as mold, mildew, lichen, and algae from indoor and outdoor structures.

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.

No Scrub/No Rinse Method

1. Apply D/2 Biological Solution with a brush or pump sprayer to a dry surface. Do not prewet the surface.

2. Allow to dry. Repeat if there are heavy biological deposits.

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 growth dies and releases.
