About the Product

NBDR-89 has been designed to assist manufactures, masons, architects and building owners to bond loose surface materials like sand or loose powdered pigments to the masonry walls. NBDR-89 becomes an integral part of the wall after application and is as permanent as the masonry itself. NBDR-89 will allow moisture vapours to escape and therefore, not promote spalling or similar failures due to moisture trapped in the wall.

Environmental and Safety Concerns

NBDR-89 is environmentally friendly, water based, non-flammable and complies with VOC and other appropriate Government safety standards, legislation and regulatory requirements.

Application Precautions

1. Verify that masonry, concrete, stucco, block - splitfaced/fluted and mortar have not been treated with any form of chemical/acid wash.
2. Verify that masonry, concrete, stucco, block - splitfaced/fluted and mortar units in existing building are structurally sound and fully intact.
3. Before application ascertain that the masonry walls have a neutral ph level or all warranties are void.
4. Alkali or efflorescence should be treated with proper neutralizing compounds as recommended by masonry supplier before application can begin.
5. Application of NBDR-89 is possible in temperatures of 30oF to 110oF . Masonry surfaces ideally should be dry before work begins.
6. The binding solution can be applied by way of a labour intensive process involving hand application, ensuring a precise application to each and every individual masonry wall, or can be sprayed.
