If you suspect that a product has frozen, contact your TBS Technical Representative or Territory Manager. ' If you inspect and determine that incoming material is frozen, do not accept delivery from the freight carrier. Safet � y Use the following safety instructions when handling TUFF-N-DRI membrane. Also review the Material ' Safety Data Sheet (MSDS), as well as the safety precautions provided by the spray equipment manufacturer. 1. Avoid direct contact with the material. Prolonged or repeated contact can cause skin irritation. ' If prolonged contact is anticipated, impervious gloves should be worn. 2. In a confined space at temperatures greater than 212°F (100°C), sufficient vapors can ' accumulate and flash if a source if ignition is present. TUFF-N-DRI Membrane will not support sustained combustion, and will not burn under normal circumstances. ' 3. Mist from spray application in a confined area can possibly cause a headache, nausea, and irritation of the nose, throat and lungs. To prevent this, a dust mask or cartridge respirator may ' be worn but is not required. 4. To protect the eyes from contact with high-pressure spray, wear chemical safety glasses with side shields. If contact with eyes occurs, flush with large amounts of cool water while holding � eyelids open. Get medical attention if irritation persists. Application Instructions � Preparation and Limitations ' 1. The block, parged block, poured concrete or pre-cast concrete must be clean, smooth, firm, free of dust, mud, ice, snow, loose mortar, wires, fins, metal projections, wall ties, or any other substance which might prevent placement and bonding of a continuous film. Take particular care , to ensure that the footing and/or cove area are clean. 2. On poured concrete walls, remove wall ties on the outside and inside of wall. This must be done , prior to the application of TUFF-N-DRI Membrane. 3. On poured concrete walls, the tie holes must be patched with hydraulic cement, vinyl concrete ' patch, or non-shrinking grout. Flat snap ties that break off cleanly without chipping the surrounding concrete, only require pre-spraying with a 10 to 15-mil wet coating of TUFF-N-DRI Membrane, but may be treated as above as well. Whichever method the applicator chooses, the ' tie holes must be prepared prior to the standard 60 mil wet application. Honeycombs or voids in the wall must be patched with hydraulic cement, vinyl concrete patch, or non-shrinking grout. ' 4. For bare block walls, all mortar�oints between the masonry units shall be compressed and tooled or struck smooth. All voids in the mortar joints between masonry units shall be patched , with hydraulic cement, vinyl concrete patch or non-shrinking grout. 5. For parged block walls, the parging must be firm and smooth. It must not crumble to the touch or , have too high of a sand content. Any patching of the parging must be done with hydraulic cement, vinyl concrete patch or non-shrinking grout. 6. For block or parged block walls, find out whether any or all of the cores of the block foundation ' are to be filled with concrete. If any of the cores are to be filled, the filling must be completed '
