D/2 Biological Solution 1 quart ( 0.946 Litres) - Price Includes VAT & Shipping

Non-hazardous and biodegradable, D/2 Biological Solution is an easy to use cleaning solution for removing harmful and unsightly biological and air pollutant staining from building materials.

Used on buildings, monuments, sculptures and headstones, D/2 safely removes stains from mould, algae, including stubborn red algae, mildew, lichens and air pollutants. Developed by conservators, D/2 has helped keep prestigious properties such as The White House and The Alamo pristine.

Use and Application

No special handling or on-site mixing is required. There are two standard methods of application. For best results, use D/2 undiluted and when air and surface temperatures are 5°C or above.

Immediate Result Method

• Apply D/2 with a brush, roller, hand pump sprayer or low-pressure power sprayer.
• Allow undiluted D/2 to remain on the surface for 10-15 minutes.
• Apply additional D/2 as necessary to keep the surface wet.
• Scrub with a soft nylon or natural bristle brush, do not use a metal brush.
• Mist lightly with water and continue scrubbing the area.
• Rinse thoroughly with clean potable water.
• Reapply if rain occurs within 12 hours of application.

A contact time of 10 to 15 minutes followed by scrubbing with a soft brush will loosen most biological and air pollutant staining. D/2 works with the elements, so results may continue to develop over the course of 2-3 days.

No Scrub/No Rinse Method

• Using a sprayer (pump-up, low pressure or other), wet the entire surface with D/2.
• Allow the solution to air dry.

D/2 works with the elements, with results occurring within one week to one month, depending on the severity of the soil. Reapply if rain occurs within 12 hours of application.
