Applications & Uses
- Applications
- Recommended Uses
PS102 was originally developed for commercial and industrial applications and is widely used throughout North America to this day for those applications. Concrete Sealers USA is now also making this professional grade sealer available to the residential market so small contractors, applicators, and do-it-yourselfers can enjoy the same superior benefits that architects, engineers, and large contractors have enjoyed for years. PS102 is recommended for curing new broom finished concrete and for sealing existing unsealed and uncolored broom finished concrete and porous concrete block.
- Surface Preparation
The surface must be clean and porous enough to allow penetration into the substrate. Surfaces should be clean and free of surface laitance, dust, dirt, debris, mildew, oil, grease, previous sealers, curing agents, paint or other surface coatings, and other contaminants. If acid or other cleaning compound is used for cleaning or etching the surface, neutralize the surface completely before application of PS102.
- Application
Always test porosity prior to application. Surface should be dry for proper penetration of the sealer. Should not apply to damp or wet surfaces or if rain is expected within 12 hours after application. Product is a one part system and requires no special mixing. Stir material thoroughly before and during application. Do not apply below 40°F or above 95°F during the application and drying period. Apply uniformly with a low pressure sprayer. When applying material, work in small, manageable areas at a time in order to maintain a wet edge. Product should be applied to the point of rejection and be fully absorbed within 10 minutes without puddles. Use a broom, roller, or brush to evenly distribute product as well as disperse any puddles as excessive application may result in white residue (especially on darker surfaces) which will not affect sealer performance and generally dissipates over time or by power washing. Generally, only one application is required. For curing new concrete, apply PS102 after all bleed water is gone, finishing is complete, and the concrete will withstand the weight of a person and not be marred. For new concrete where additional product can be absorbed, a light secondary application of PS102 may be able to be applied any time after 24 hours to enhance performance. Clean application materials with warm water.
- Limitations
PS102 is designed to work only on porous concrete and masonry substrates and is not intended for asphalt. This product may damage vegetation or may etch glass, vinyl, aluminum, plastic, and metal. Avoid contact with eyes and skin. Sealer may be damaged if frozen prior to use. Not intended to seal cracks. Will not remediate structurally unsound surfaces with defects. PS102 is not oleophobic and is not intended as an oil repellent.
