07 19 00 | No. 8789-000 | Print Version | Safety Data Sheet

DESCRIPTION

RAIN-SHIELD STAIN OP WB is a waterborne, water repellent, penetrating stain, providing long-term protection against elements.  It provides colour uniformity and corrects colour imperfections of the substrate to beautify and significantly extend life of structures.

USES

RAIN-SHIELD STAIN OP WB is a liquid, non-flammable protective stain for sound walls, bridge structures, median barriers, retaining walls, and tilt-up panels. It also provides architectural finishes for vertical walls, such as concrete, stucco, block, and brick.

APPLICATION

Surface Preparation … Surface must be clean and free of dust, dirt, and other contaminants. The surface to be treated must be dry to allow good penetration of RAIN-SHIELD STAIN OP WB. All caulking, patching, and joint sealing must be installed prior to application of RAIN-SHIELD STAIN OP WB.

Mixing … Mix thoroughly (approximately five minutes) before application.  Do not thin.

Application Method … Use airless spray equipment capable of delivering 6980 KPa (1000 psi) & 1.9 L (1/2 gal.) per minute. Heavier equipment can be used on larger projects. A self-cleaning reversible tip with orifice 0.330-0.425 mm (0.013” – 0.017”) and minimum 40° fan angle is recommended. Roller or brush can also be used, but uniform application is essential for obtaining an even, blotch-free surface. Establish break lines confirming to surface design breaks where possible.

Curing … RAIN-SHIELD STAIN OP WB is air-dry cured. It will be tack-free within ½ hour and fully cured within 3 – 5 days, depending upon temperature and relative humidity.

Cleanup … Clean all spray equipment and hoses immediately after application with water. Dry material can be cleaned using polar solvents (e.g., acetone or other ketones.

LIMITATIONS/PRECAUTIONS

RAIN-SHIELD STAIN OP WB should not be used below-grade.  The product will not stop water penetration through hairline cracks under wind-driven rain conditions exceeding in size 0.025 mm (0.001”).

No maintenance is required. RAIN-SHIELD STAIN OP WB is self-cleaning.  The atmospheric dust collected on the surface can be easily cleaned with water and detergent. If repair is required, apply more of the same product.  Resealing of the wall may be required after some time to provide continuing water protection.

HEALTH AND SAFETY

RAIN-SHIELD STAIN OP WB is non-toxic and non-flammable. Do not take internally.  Keep out of reach of children. If contact with skin occurs, wash with soap and water. Harmful if digested.  FOR INDUSTRIAL USE ONLY. Consult SDS for additional information.
