TYPE:
Shelby Concrete Plastic Sealer #19 is a clear liquid composed of synthetic resin dissolved in hydrocarbon solvents. It seals and protects concrete surfaces against water intrusion. It is a deep-penetrating and water-proofing reactive chemical containing no silicones, oils, paraffin waxes, urethanes or sodium silicates.
 
USE:
Best for concrete and masonry surfaces where water seepage is a problem. 
 
SURFACE PREPARATION & APPLICATION:
Surfaces should be clean, dry and free from grease and oils. Apply by brush or spray. Under average condition, a period of at least one (1) hour should be allowed between each coat, if two coats are necessary. Fresh concrete shall be allowed to cure for thirty (30) days prior to application of water-proofing to ensure satisfactory results. A minimum of 15% moisture content of the new masonry should be observed.
